Advanced Evasion Techniques for Dummies
Information technology (IT) evolves and transforms the entire world. Since, time immemorial race of human civilizations practices various methods to reduce the distance between places. Mode of communication enables all of us to reduce distance between faraway places and increase constant touch among known persons even if they are a long way away. It is the sheer human analogy to find out what has not been seen and this enables many new voyages in the past from west towards mysterious eastern side of the earth. Most of voyages had been through oceans which many courageous voyagers have taken the upper hand in facing imminent dangers and unknown tidal heights. They discovered many new places and repeal the phobia that the earth is a place and somewhere one can fall from there to alien space called universe. Slowly, realization comes to earth is a sphere and in no ways we can fall to empty space of the universe.
Human is a rational animal and cannot live without relationships. He cannot stay alone. He wants to create associations and collaborations and this creates urge to connect with others that have enabled multiple ways for humans to ponder upon newer reaches towards unknown entities. With the advent of computers more and more form of collaboration and coordination among different spheres of the world through different physical servers has become a reality. Many multinational companies (MNCs) are now interconnected in providing non-stop access to clients at different locations of the world due to installation of industrial servers at different locations. It empowers companies to manage information with a single click of a computer button and most orders, tenders, and catalogues of logistic management are now possible through industry servers.
Security protection model:
Clients publicly give out some private information to industrial server for identification and authentication of real persons. It is done to create a seamless relationship between client and industry. On the other hand, it is evident that these informations are vital and companies must ensure strict vigilance in order to obtain this information in a well-guarded manner. Many competitors of companies always want to lurk into such information of clients in order to steal business. Most times, market leader has to face the brunt of difficulties of stealing these data from industrial server. Database of market leader is always prone to attack from its competitors in two senses. In the first sense, the mode of attack is made to create more and more server downtime, in order to bring down percentages of time capture on similar services. In the second sense, industrial servers of market leaders are always attacked in order to steal information about clients and entangled market leaders in the legal battle over spreading of private informations of individuals.
In Europe it is legally binding for industries to protect the privacy of clients and individuals in the highest manner and this in modern times, security of industrial server has become a major preoccupation among in-house security specialists. Hackers and attackers employ advance evasion techniques (AETs) to simulate attacks on industrial servers through disguise of packet network correspondence. Security protection model of industrial server is an extremely important tool for attacks from different hackers. They know in order to gain administrator rights; they have to pass through different development evasion techniques through the process of invisible modules that has been ignored by in-house security specialists of industrial servers.
Threat landscape on traditional security models are potentially on rise:
Advance evasion techniques (AETs) break security protection model of most organizations. There are not any clear-cut formulae to stop such attacks and anticipate such attacks beforehand. Attacks of AETs are mostly towards traditional security models and gain the upper hand and completely stay invisible within the same set of network operations inside industrial servers. Given this rising of advance evasion techniques, threat landscape on traditional security models is potentially on the rise. More and more industrial servers who are employing traditional security model as their correspondence server have been under relentless attack from AETs. Traditional security models are facing threats from development evasion techniques because of heavy server side limitations of their functions.
Cybercriminals use AETs to employ covert and undetectable methods to penetrate deep into protected network systems. Legacy industrial servers run with traditional security model which is handicapped over attacks from advance evasion techniques which bypass traditional network models to invade deeper system configuration and overtake administrative control of industrial servers. Traditional security models of industrial server run with the practice of common network solutions. Common network solutions run with security devices, network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). Many industrial houses do not possess sufficient knowledge about what kind of risks AETs represent to their business. Security professionals must update their knowledge and adapt to changing security dynamics. This writes up arms to observe the Internet from the point of view of cybercriminals to understand natural security situations from around the world. Traditional security systems run with layered security that constitutes of network router, hardware firewall and intrusion prevention system (IPS).
The internet is a wild world having no policing. Attackers and hackers have open and field to search for server vulnerabilities which are interconnected all over the world. Due to nature of business and other specifications, server of most of multinational companies (MNCs) is always online and there are many such public to private transactions going on from within their server. Even if an attacker and hacker are caught red-handed, there is no such aggressive international criminal justice system which can try to handle cyber criminals in a court of justice. Internationally, criminal actions performed by cybercriminals performed in internet perceived as a low-risk environment. Most of sentencing of cybercriminals in the international justice system are very low in character. Huge scales of potential rewards for hackers are still there.
Infamous conficker worm:
Most times, victims who have lost fewer amounts of money resulting out of hacking of bank account have less bothered to report to cyber police. They remain silent. Cyber criminals, try to steal few amounts from a large number of personal bank accounts which always gets unnoticed and unreported. Security professionals of industrial servers have a tendency to ignore such small attacks from hackers. Hackers try to initiate such progress evasion techniques to hide behind small attacks to manage and set for bigger attacks in future. Modern cybercriminals have become more industrialized, organized, sophisticated and enterprise. More and more black-hat professionals enter these businesses which are very well supported by numerous countries and big business houses. Big business houses take the help from hackers to look into classified informations of immediate competitors from the same business segment. Hackers initiate two kinds of attacks. One is network-based and the other is host-based. Advanced evasion techniques (AETs) concentrate on network-based attacks.
Attackers send targeted attack to industrial network server and try to intrude into targeted device and then remotely control it. Network security device is placed between attackers and industrial server which aim to provide security to industrial server from invading advance evasion techniques. For AETs targeted devices with compromise of laptop or enterprise servers. This is then proved that AET attacks are not limited to enterprise and industrial servers only. Most of modern attacks on AETs target specific enterprise resource planning servers (ERPS). Attackers target specific industrial servers through scanning of multiple network zones. The configure worm first detected in 2008, was a glaring example of how a simple evasion technique attacks renowned industrial servers worldwide and stays inside their server for so long invisibly sending vital information to rival camps. More old Windows server computer runs with the principle of remote procedure call request (RPC) which creates collaboration management remotely to different location servers.
Target device of attackers:
Conficker worm uses a specially crafted RPC, to force buffer overflow on network servers, to inject infected shell code on industrial servers. Buffer overflow condition is a condition related to exceed limits of network capacity within specified time limits. Infected shell injection controls the entire network of industrial server and stops inward as well as outward movement of network transactions. Conficker worm mute intrusion detection system (IDS) completely for some period, gives additional time to attackers for a completely vulnerable unmatched system in order to initiate attacks advance evasions techniques (AETs). According to Microsoft’s Security Intelligence Report from April 2012 at one time during 2012, 220 million computers worldwide were infected with conficker work for more than two years. Surprisingly, most of these systems were well secured with highly trusted security software from famous security software vendors were installed on them still all these systems were not well protected from imminent attacks of advance evasion technique (AETs). The preliminary task of hackers is tantamount to collect comprehensive collective information from information technology (IT) department from insiders. In this way, they garner the geographic location of a physical server which is the target device for hackers to attacks with advance evasion techniques. They get information from people who are working with inside company. There are a number of sources of information and hackers go for trial and error method to utilize all such gatherings of information.
The internet is a vast resource for gatherings of all sources of knowledge. Every company has internet presence and plenty of information regarding such companies can be collected from simple internet searches. Hackers dig up for more information about the target device from different sources. Hackers are very meticulous in their approach to this. They search for vulnerabilities within the targeted device. Hackers have sufficient knowledge about ongoing internet vulnerabilities cropping out from different unmatched operating systems and applications. Security experts in bigger organizations should use constant security audit of unsecured ports and susceptibilities in application architecture. Hacker collects most information about the target device and then decides which type of attack to be initiated in order to have complete control over administrative rights of targeted computer. Attackers then create their own code and send to target device through a reliable remote connection through simple command prompt from the computer. Security updates and patches are meant to protect industrial server from imminent attacks. In practice security patches create additional vulnerabilities.
Creating totally bug free software takes time:
Are there any methods to make totally bug-free software? Many developers feel creating totally bug-free software is still a myth. Making such server or huge software takes huge time. Generally, for every thousand of lines of codes you can have at least three bugs. Creating a totally bug free software takes huge time and there is not any such guarantee and there is no such full proof plan for this. Operating systems have million lines of code. An industrial server has unbelievable lines of codes that are out of human comprehension. Internal quality testing is not automated but done by some other professional as they are required to make mistakes. Microsoft releases service packs for updates to fix many bugs and security holes in codes of operating systems. In 2005, Toyota recalled 160,000 Prius hybrid cars following reports of unwanted and unwarranted warnings lights illuminating automatically for no reason stalling moving engine unexpectedly. From complete research, it was found that there is a bug in the operating system of smart car which was embedded to create greater smart environment from inside car. This illustrates how a perceived smart car which runs with some computing goes totally wrong to stop engines of cars completely. This proves that when a software code goes completely mistaken the corresponding hardware server also behaved in different manners. Bugs in codes of software can open the floodgates for hackers to intrude into the target system by means of attacks of AETs.
Daylight saving time:
There has been a misconception about the relation of hardware in consonant with the software environment. It is not the case at all. Every hardware works accordingly to the software environment and this environment is called as smart environment. Software controls hardware and entire hardware can be controlled with software environment. The problem arises when software has bugs or security holes. Bugs and security holes inside software architecture can allow back door entry through sophisticated advanced evasion techniques (AETs). Fixing of bugs by software vendors does not constitute an automated process. A team of developers always scans through vulnerabilities of software environment and then through process re engineering methods patch these critical security holes. Till to date, there is no single process and method to create an automated patching of security vulnerabilities in the software environment. A time window that exists between discovering a bug and coming up with solutions in deploying the fix on the server is known as daylight saving time. During this time, industrial server remains completely untouched and unattended. Hackers wait anxiously for this time and then initiate attacks on target servers. That is why many industrial servers run with different time zones, specifically time zones for US in order to minimize vulnerability time of servers.
Attackers invade codes for injections into industrial and productivity server to completely gain the upper hand in their functions. In simple term, daylight saving time is the time window that exists between discovering of bug, security holes in the software environment and reaching a solution and then installing that fix in the software environment. Security patches fixes immediately certain parts of industrial servers, but it also open several vulnerabilities which require constant patches and security updates. Patches fixes some part and in future breaks some other part and makes a continuous process of patching and updating industrial server. Security analysts must ponder upon different methods to look for such vulnerabilities at the earliest so that they can reduce daylightsaving time and create a completely secure operating system. In short, patches may introduce a new problem for the business software. Patches of business software is essential, but it does have side effects.
It is always difficult to patch critical production server:
Business software on productivity servers poses difficulty in installing scheduled patches. It is not easy to restart productivity servers at one go as it can cause a huge loss to the exchequer in terms of time, money and reputations. Big industries cannot be out of action for long as it can hamper brand values and remove loyal customers who have taken the status of companies so far due to constant backings from their side. This increases the time interval and gives ample time to attackers to initiate a series of attacks to production servers. It is always difficult to patch critical productions server such as industrial machine controller or nuclear reactor controller as one second of disturbance of such servers can result in some mighty technical faults. Advance intrusion prevention system (IPS) can temporarily fridge advance evasions techniques (AETs) initiated by attackers. IPS does not constitute a complete solution to wipe out AET attacks. IPS techniques adjust time interval of day light saving times thus gives security professional additional leverage to create a security patch and install those patches on vulnerable productivity and industrial servers.
Advance intrusion prevention system is a modern tool used by network security specialists to create virtual patching and layered patching. It minimizes daylight saving time in order to reduce buffer overflow resulting out of continuous attacks from development evasions techniques. Advance intrusion prevention system continues to scan the entire network and treat the entire industry and productivity server as a single unit in order to completely scan each factor of network movements. Advance intrusion prevention system also fails many times against imminent attacks originate from AETs. For this, it has become a serious issue concerning security of industrial server and productivity servers of large organizations. It is like, you are staying in a conflict zone and you have looked everywhere but failed to lock up the back door of where criminals enter into your house. AET is an invisible threat. It is developed by intelligent hackers.
Most of security invasions come out from dim internet protocol designing which originates from connectivity of network servers throughout the world. For better security, a robust internet protocol designing is needed. Internet protocols are often complicated process, creating out of hearty designing of internet security which stops evading advance evasion techniques. Internet protocols are important network connectivity solutions which are a gateway to different network connections to clients. There are some internet protocols which are difficult to manage and some are very rarely used by network servers.
Abstract and distracts methods of code injection:
Some system administrators use a moderate approach to even activities of unused network ports. Sometimes, concealment techniques implemented by attackers through attacks of development evasions techniques many a times go unnoticed due to careless attitude of system administrators. Advanced evasion techniques (AETs) successfully carry malicious codes to deliver deep into industrial server without detection. It creates new technology to hack into productivity servers at larger organizations. Sometimes, it combines so many techniques to create a hybrid technique to bypass several layers of network security. AET has ability to change the mode of attack during attacks on industrial servers thus creating a different dynamic evasion techniques which can change with nature of defense imposed on secure servers. Configuration of AETs depends upon such abstract and distracts methods of code injection that many a time’s secure servers are unable to detect and consider them as normal network flow within ports of internet protocols. Principle of advance evasion techniques (AETs) consists of three simple techniques such as insertion, evasion and denial of service (DoS). There are three simple techniques used to bypass devices for network security. AET provide sufficient space for attackers to change the detection techniques in case of apprehension of detection of attacks in midway from devices to network security.
It is evident that there are no such research papers for them to rely on it and for this they have to deal with these threats from their own intelligence. This creates an easier situation for attacks of AETs as they are now facing with network security which is still at its nascent stage. Even most of security vendors are now handicapped with this technology and they are creating own research and development (R & D) team to create an automated development evasion testing tool to protect network security products. Due to dynamic nature of AETs most of network security products cannot detect it while the attack remains in. Researchers have found about in understanding the mode and nature of advance evasions techniques (AETs), and more and more hidden evasions comes to light. It gives to show that for every protocol the nature of AET is different. That is why; it is always challenging to prepare a network defense against attacks of AETs as the mode of operations changes in every case. There is no standardizing AETs formula so that security professionals create an established defense system on it.
Automated advance evasion testing tool is still in its nascent stage:
In recent times, there are many development security firewalls as well as intrusion prevention system (IPS) to defend attacks on networks. This is an alarming situation and definitely doomsday for entire network security servers. This goes on show the response time of productivity server is too less to act. Two seconds to defend system and create and install a patch is difficult and for this many security farms decide to create a stealth method in order to fridge such imminent attacks for some time in order to get suitable day light saving time to install security updates within productivity servers. This situation is similar to the situation which existed 15 years ago to antivirus industries, where they knew about existence of large number of viruses but no one in the industry could spell out how extensive the problem was then. The scope of AETs is vast and it is important for security experts and network administrators to clearly understand what this is about and how this works.
Just imagine the number of different types of attacks of AETs can be with the principle of the binary number that has 147 digits to two, a truly humongous variety of potential combinations which is always difficult to guess for security professionals. AET work just like nanotechnology which constitutes on the principle of multiplication in order to create massive objects with numerous similar small instances. Latest research has shown that some of these AETs are so deadly and dangerous that they create their own defense system and work like a tiny industrial server while carrying out attacks on large industrial servers of big enterprises. It seems the only solution to this ever increasing network security problem is the automated advance evasion testing tool which can change its course of defense in accordance with nature of attacks originating from different unknown sources. Automated advance evasion testing tool is still in its preliminary stage and it requires huge research and development team with superior expertise to develop such tools.
Application processing information:
AET target traditional security devices. It does not purely depend upon protocol properties. Most security software runs with the principle of scanning networks and AETs work in a different manner. It can be invisibly open closed ports and there is no way security software is going to find such open ports. All these create worrying trends and it is a challenge for security professionals to learn and understand how AETs work. It is high time to think of some unusual combination of network attacks. AETs do not depend upon the usual combinations; it works with different unusual trends and protocol formations which security professional has to understand it better to know the nature of attacks on industrial productivity servers. AETs constantly attacks productivity servers through some unusual combinations. It exploits technical and inspection limitations of security devices through exploitations of memory capacity, performance optimization, and design flaws. Traditional network security is completely ineffective against attacks from advance evasion techniques in similar manner traditional radar are ineffectual against modern stealth fighter attacks. AET take advantages of weak protocol anomalies and violations. These vulnerabilities appear due to flawed implementation of commonly used internet applications and browsers. Network traffic works in layer principles and most protocol irregularities occur owing to flaws in these layers. Security professionals need to analyze discrete layers of network traffic layer by layer and manual detection and scanning of log files is a good option to detect signs of concealment of AETs from within network infrastructure.
This process of scanning entire network security is called as network traffic normalization and proper and intimate analysis of every fitting layer can produce revelations of any conceal malicious codes of AETs. The infamous Conficker worm is a simple code injection which stays invisibly inside Windows server computer by bypassing legitimate security software. When it is initially detected, it comes out openly that it stays invisible undetected creating more havoc all over. That is why Microsoft creates Windows 8 by completely overhauling security environments and connecting authentication processes to hardware application processing interfaces (APIs). Windows 8 depends so much upon hardware security than software security. Two factor authentication of Gmail are stronger and securer more with hardware authentication. Android phone is used as two factor authentication, mechanisms in order to give greater security to the gmail account.
A simple experiment of creating AETs worm:
There is some work around with some applications which can bring about 90 percentages of Gmail account open. This is worrying trend considering it is the primary email account for most users. Awaited to flexible and always on availability, it has slowly become ubiquitous email account for all of us. It is evident that hardware security is impossible to crack even by dynamic advance evasion techniques (AETs). Transmission control protocol or internet protocol (TCP/IP) network is built on sending and receiving of informations through packets. It is common to use lesser packets in order to increase the speed of transmission. As a result of this, fewer ports are utilized and rests of ports are remaining unused for most of the time. These unused network ports remain constant and most times security experts do not believe that about it as they perceive as no traffic communication is there and for this there should be no breach of security from these ports. Let us consider a small experiment where collect some conficker worm from a legitimate security web portals. In Internet, there are some sites which offer virus samples for testing and creating antivirus updates. You can get those samples for free for testing purposes.
Test it on an older or legacy desktop computer and do not test it on your innovative laptops as there are chances of getting infected while performing this experimentation. Now make two fragments of this conficker worm. Then send it to two separate networks meant exclusively for testing. Install updated security software on both network servers and do not forget to update its operating system with the latest security updates. What is reason for this not detection of these worms? Conficker is a form of advance evasion technique which works differently when introduced in the form of two separate identities and it goes on to show, how a known malwares changes its characteristics completely when it is divided completely. It is a smaller example how a single AET worm can change its characteristics when it is separated into two segments. Sadly, when it is changed this approach, network security devices will not detect this which results into completely hacking of productivity and industrial servers. From this example it is evident that, when advance evasion techniques segments worms into many different segments and then while in the process of attacks it also combines some segments to becomes some other form of malwares, is obviously the single most dangerous viruses attacks to server computers which many information technology (IT) specialists would never ever think about it.
Why are such robust network security devices always fail to predict and intercept these attacks?
Network security devices or server need to handle million of connections in a single second in some ports. It restricts connection to some ports due to security and speed. They can hold network traffics in memory for fewer seconds. The normal amount of memory allocated for the inspected traffic is about seven seconds per each connection. Then, that connection goes into a phase of time out and then it is deleted from server’s memory. In the above conficker example, two fragments are sent each to two different network servers within the space of ten seconds. Deliberately the time interval between two servers is being kept longer considering default amount of memory allocated for the inspected traffic is about seven seconds per connections. In the first seven seconds the network device will partially match two fragments and then it will leave the inspection on those connections. As both worms are releasing in ten seconds apart, then it cannot match the entire configuration of the network and are able to complete a positive match to the detection fingerprint inside network security devices. Within time frame of seven seconds the conficker worm will reach in some parts and in scanning those parts, network security will find nothing as it cannot wait for ten seconds, and it will pass this worm as legitimate traffic to network in legacy server systems.
Network security packets inspect many packets coming out from different networks from different internet protocols coming out from different servers throughout the world, and after a few seconds it stops detecting longer traffic and that is why rise of such vulnerability exists in legacy servers. That is the reason why the introduction of hardware firewall and hardware intrusion detection system can work tirelessly scanning innumerable network communications without any disturbances. Windows 8, Android and Apple are built-in consonant with distinctive hardware vendors to stop attacks of advanced evasion techniques (AETs). Hardware Intrusion prevention system (IPS) works differently. It can store a huge flow of traffic information and the trend of buffer overflow does not impact on it as this can create multitasking in its supreme form to scan different network traffics through TCP/IP. It constantly scans for stored internet protocol for longer time to detect any sign of attacks of AETs. When, fragmented-conficker worm comes near to hardware security, it slowly keeps that information and then scans it in the first part and then bridge it in the second part in order to make a complete safer network security. It creates an event log of the server, and early warning which ensures automatic conversions of administrative rights of the server to standard rights where such attacks of advanced evasions techniques will simply evade from the scenes.
Enhanced mitigation experience toolkit from Microsoft:
In its latest version of Windows, Microsoft introduces, new incarnation of enhanced mitigation experience toolkit (EMET), which anticipates the most common form of invisible attacks from advance evasion techniques (AETs) by stopping additional vulnerabilities in computer systems, and diverts and block indicating those techniques. Virtually, every product has to deal with software vulnerabilities and exploits. Results of attacks from AETs can be catastrophic malware infections or loss of personal identification information (PII). There are heavy chances of the loss of business data which can incur heavy losses to overhaul financial health of an organization. EMET performs continuous through scanning of entire network traffic searching for any signs of vulnerabilities. Most of intrusion prevention system (IPS) and data execution prevention (DEP) require separate installation of application to implement the program. If that application is hacked then entire purpose of IPS and DEP has gone into astray. EMET from Microsoft which is free for Windows server is especially useful for software where patches and security updates are not available. It is also handy for obsolete software where the source code is not available. It works on dynamic principle just like attacks of AETs do.
It works in reverse-reengineering manner to eliminate any trace of invisible attacks. EMET provides security specialists a horde of choices to work on with such as divide each process with a different level of mitigations. In information technology, mitigations are expected paths of attacks from AETs where, achievable frame rate of network transmission is considerably reduced. Numerous productivity servers are reluctant to remove legacy applications because; they pose easiness to clients while dealing with front end databases. Legacy applications are those applications which are no longer supported by their developers. In some cases, developers die then that application is otherwise known as legacy applications. In some case, companies disown those applications after a certain period of development. Windows XP is currently a legacy operating system. It is no longer supported by Microsoft. Legacy applications cannot be rewritten and it is required to phase out from the scheme of things slowly. Big organizations cannot instantly retire legacy applications as there are certain pecuniary as well as other issues are attached to it. Unfortunately, such applications can pose heavier security risks by showing software vulnerabilities. EMET can help to harden such application and makes it difficult for hackers to find attack point in industrial server. EMET helps security specialists to help and verify fraudulent SSL certificates to stop recurring attacks of AETs. EMET enforces stringent sort of SSL certificates for specific domains to allow configurable certificate pinning. EMET works differently from further intrusion prevention systems. It does not require a third party installation. It does not prescribe constant updates. Installation file of EMET is small and it is fast and works silently in the background helping system administrators immensely. It provides cutting edge mitigations technologies against modern cyber attacks. It comes from Microsoft and it mixes well with a Windows server. The release cycle of EMET is not associated with any product. It can work seamlessly with legacy windows server such as Windows media editions as well as it can work brilliantly with the latest version of Windows server which works diligently with hardware security measures. EMET is a set of toolkit to protect server and individual networked computers by creating a set of several pseudo mitigation technologies to counter attacks on development evasion techniques (AETs). EMET give security professionals a free hand to construct the system policy of mitigation on a per executable basis.
EMET employs hardware logic of signature matching:
EMET supports mitigation for system processes, per executable processes, configured applications, and provides a certificate of trust constantly updated and synchronized with the cloud of Microsoft servers. SSl certificates are designed to bind specific rules with root certificates of servers to observe and report any discrepancies in server activities. EMET does use light system resources, and does not function as a process. It runs behind the scene through application compatibility framework of Microsoft. There are absolutely no compatibility issues attach with EMET but sometimes some exceptions here and there. High voluminous network traffic with too less memory is always vulnerable to network attacks from AETs. Modern network security devices are running with 64-bit architecture in order to distribute more memory to server while dealing with network transmissions. It gives additional room to security experts in dealing with continuous attacks from network servers. Many industrial networks sacrificed speed over network security. All four layers of TCP/IP protocols of devices are not inspected properly and it poses additional vulnerabilities and creates target point for attackers. All traditional network security servers work on the principle of signature-based inspection of virtual packets known as pseudo-packets. When all four layers of TCP/IP are enabled, it makes network communications slower but it considerably improves network security and the entire productivity server of organizations.
It is difficult to redesign older security devices into newer ones as it is unique for every organisation and the entire process of redesigning take a huge chunk of time. Most organizations have their unique identity and redesigning of each organization is different and it requires huge investment of financial resources for research and development (R & D) in order to build a superior infrastructure. Normally, research and development (R & D) takes time and it requires massive investment. That is for this reason that still to date most organizations have been unwillingly to update their legacy systems. In an industrialized business environment, proper combination of newer hardware requirement compatible with modern security software takes lesser central processing unit usages (CPU) and a lesser strain on the entire server. This results and empowers server to watch out for the entire network infrastructure without lack of any such extra memory usages. In this way, it closes on exploits and locking patterns and then moves towards a seamless security environment. Due to high-end CPU capacity, industrial server can work with data stream based information mechanisms, each network packets of the entire network infrastructure can be thoroughly verified and inspected. Due to introduction of hybrid software and newer software-offload technologies lesser load on CPU provides an environment to reduce stress of entire processing units. In this way, most of these attacks on AET which aim to destroy outdated security installations fail to exploit signature based inspection mechanisms. It implements hardware logic of signature matching and it connects to enterprise cloud security in order to stay updates all the times. Owing to presence of cloud security, latest updates are received by the server and then they utilize those updates to stop exploits from attacks of AETs.
Programmable logic controller (PLC) for automated detection of attacks of advance evasions techniques (AETs):
Cybercriminals like to utilize minimal methods and fewer seconds to execute attacks on advance evasions techniques (AETs). They prefer cut-down approach as they are not certain of which industrial server they will be hacked into and they constantly try to hack server day in and out in order to locate security vulnerabilities. They knew, to have lesser time as these vulnerabilities are about me be patched sooner and for this they attempt to execute their attacks through buffer overflow and dynamic evasion techniques. AET is a difficult technique and for cyber industries, it is always a challenging to hire such black hat professionals as they demand huge money and people with big brains and time usually goes with this in order to create such massive attacks of advance evasions techniques on industrial and productivity servers of large organizations. Cyber industries expect to incur huge benefits from attacks of AETs and that is how they invest huge money on cyber professionals. Owing to the advent of entire information technology (IT) network infrastructure, the role of industrial control system is always important and it has more significance as it categorizes administrative responsibilities.That is the reason why industrial control systems are always been potential target zones for an attacker as they knew if they succeed in overpowering this system then simply they can control the entire productivity server of an organization. In simple, attacks of AETs employ conventional attack system and does not rely too much on complicated hacking methods. Organizations that are sincere in maintaining their server of installing security updates and scanning entire networks zones are far more secure and attack of AETs can need to be done to their servers.
Most of time such attacks are possible due to limited exposure of cyber security professionals and for this it is relevant for these professionals to gain more knowledge about basic end to end point security and try to implement such security measures from within infrastructure of industrial security set up. Every organization is at risk of attacks from hackers. No organization is risk free. Organizations such as government, banking, and critical infrastructure are at higher risks from attacks of hackers. Non-profit, local and service industries are at lower risk of attacks from cybercriminals. However, when these services go for financial, commercial and political value offerings to organizations, then they face the most serious brunt of attacks of AETs. In modern times, numerous such attacks are meant to satisfy ideological ambitions of some organizations. For this, many countries have invisible support to such hackers and have been spending a huge sum of money in order to develop newer technologies associated with AETs. Hi-tech, media and retail industries have an intermediate probability of onslaught of advancing threats. Many security software vendors have tried hard to develop programmable logic controller (PLC) for automated detection of attacks on advance evasions techniques (AETs). Modern industrial servers go for hardware PLC. Hardware PLC is secure than software PLC. Software PLC can be hacked if attacks of advance evasion techniques performed from a remotely located hardware dashboard.
Server overload and denial of service (DoS) attacks:
It is difficult to have fully automated detection of attacks on advanced evasion techniques as there is no standard rule set of how malwares work in a certain way before executing and injecting attacks. Many industrial as well as productivity servers are now protecting themselves with hardware security coupled with extensive scale all round layered security cover. If the system administrator goes on with signature based approach, it would be awkward for him to detect the sheer amount of different combined attacks of AETs. This is where the problem increases and due to non recognition of signatures, network infrastructure of industrial server simply by passes all these informations and then attacks of AETs become successful. Human mind has limitations and it cannot perform beyond certain levels and for this it is essential to devise some other forms of detection mechanisms to counter such massive floods of informations within the fewest possible of time. That is why traditional signature based approach would be unimaginable to think owing to massive buffer overflow of informations causing server overload and denial of service attacks. Modern security professionals use network normalization techniques which encrypt entire network traffic and decrypts on user’s recommendations. There is no need for signature based approach as entire data is unreadable even after hacking. Modern security professionals use network normalization techniques which encrypt entire network processes and turns them into a single homogenous network units thus it creates a stronger server presence in front of imminent attacks on advance evasion techniques (AETs). Attacks of AETs come to advance persistent threat (APT) to hide their original intentions to perform successful attacks on targeted devices. It is the duty of security experts to identify and trace routes of advance persistent threat and foils such attacks before they are totally encapsulated.
By identifying APT, security experts can encrypt access of critical system paths completely. In layman’s language, AET is nothing but a simple set of identification tools for cyber criminals to hide their attacks. More and more industries are being digitized and due to rapid growth of industrialization and digitalization of data, attacks of AETs pose serious challenges and threats to industrial servers which always aim at creating always on connectivity options for clients. Traffic normalization techniques reveal actual traffic and detect bots and AETs and send malicious traffics to spam zones. It keeps real traffic and sends and encrypts them and sends clients decrypt key in order to protect data all over through transfer zones. It needs extreme technical proficiency and expertise on the part of security professional to detect and destroy attacks of AETs completely by employing robust rules of traffic normalizations. Security experts’ deal with traffic normalization techniques on industrial server gives full administrator rights to deal with entire network infrastructure of industrial servers. Network administrators should always stay agile and alert and should constantly scan network traffics and from time to time should provide a suitable security environment for industrial server. It reduces the chances of attacks of advanced evasion techniques by limiting generation of a number of multiple signatures based authentication systems.
