1. INTRODUCTION
In the 1950’s era, Computer Networking became the focus for communication in military radar system and it evolved in such a way that currently approximately 9 billion devices are connected over the internet. Computer networking is currently used for business and personal use. But, this connections among devices are being misused by malicious users in the form of internet attacks. These attacks pose threat on continuously growing internet which must be defended by a security defense system. The factors that a security system should provide is integrity, confidentiality and availability. Intrusion detection system is one of them, which monitors the network traffic for possible attacks and reacts to them by either alarming security officer or by performing any of the customized action. Currently, lots of research is being conducted in this area and it is seen that artificial intelligence plays a major role and works effectively in developing this kind of system. Hence, the objective of this paper is to portray methods and areas of artificial intelligence being used in different types of Intrusion Detection System. We will elaborate artificial intelligence algorithms and detection principle commonly used.
2. OVERVIEW OF INTRUSION DETECTION SYSTEM
2.1 Networking Attacks
There are four major categories of attacks:
Denial of Service(DOS) : It is an attack which makes the attacked machine busy such that it is not able to serve legitimate client (eg apache, smurf, neptune, ping to death etc).
Remote to user attacks(R2L) : Is an attack, in which attacker sends packets to a host machine, which does not have access by exploiting vulnerability and have control on that host system by having access host user privileges. (e.g...

...a flood of packets. Therefore, the victim node or sometimes the whole network can get easily paralyzed [24].
In the past few years, cyber-attacks have grown dramatically and it is up to Information security analysts to come up with solutions to prevent hackers from stealing vital information making issues for computer networks. Information security analyst’s main priority is to protect a company’s computer system from getting attacked by hackers. It takes a couple of things to become an ISA, but it’s a well worth and well-paying job.
The Aim Higher College’s system administrators and network engineers have described seeing some strange behaviors such as high levels of traffic from many hosts that are causing system outages. The web servers of the college have been shutting down frequently by this traffic, it must be from a hacker group trying to attack the school with malicious software. I will review the network traffic from the college’s intrusion detection system and use an intrusion prevention system to block off these threats from the hackers.
It seems that DOS attacks and other forms of cyber attacks are not under Computer misuse Act legislation ( misinformation and ignorance from many sources such as some webs of IT security specialists) but after consultation with an international law firm that doubt was resolved,and Compuer Misuse Act encompasses a wide range of activities including DOS attacks.
Unauthorised acts with intent to impair, or with recklessness as to impairing, operation of computer, etc.
There are many types of intrusion detection systems, network intrusion detection, host based, protocol based, application protocol bas...
Neural Networks A neural network also known as an artificial neural network provides a unique computing architecture whose potential has only begun to be tapped. They are used to address problems that are intractable or cumbersome with traditional methods. These new computing architectures are radically different from the computers that are widely used today. ANN's are massively parallel systems that rely on dense arrangements of interconnections and surprisingly simple processors (Cr95, Ga93).
A DDoS attack, also known as a denial of service, is a prevalent cyber threat for businesses that rely on web application servers for online services. There have been many high profile cases over the years of DDoS attacks on different online networks. The black hat hacker group known as Lizard Squad attacked Sony PlayStation and Microsoft Xbox videogame networks in 2015. A hacker group known as “Anonymous” launched a DDoS attack in retaliation of the Federal government’s decision to indict the executives of Megaupload and forced the shut down of the file hosting website. Cyber-criminals are also known to use DDoS attacks for cyber extortion of money by threatening a business with DDoS attacks unless a ransom is paid.
attempt to force a network offline and unavailable to its intended users. This process is typically performed by flooding a network with communication requests until the server cannot respond to the traffic, thus making the server go offline and become available. This process is relatively simple to perform to the average person through online programs. Since it is so easy perform, it has become a rising issue simply because anyone has the ability to hack into various servers. One example in recent news of DDoS attacks comes from Riot Games, developer of the popular online multiplayer video game League of Legends. After a month of inconsistency with their server stability and frequent shut downs, Riot Games reported that within the l...
Although Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) have been grouped together here (IDPS), there are distinctions between them. On the most basic level, both will monitor the network...
When someone suspects that an unauthorized, unacceptable, or unlawful event has occurred involving an organization’s computer networks or data-processing equipment Computer security incidents are normally identified. Initially, the incident may be reported by an ultimate user, detected by a system administrator, identified by IDS alerts, or discovered

“ Prevention is better than cure ”, if computer users are aware of Malware attacks, they may prevent those attacks . So, in this research paper i am going to focus on Malware and Protecting Against Malware.
Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors. In fact, according to several studies, more than half of all network attacks are waged internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, an...
Artificial neural networks are systems implemented on computer systems as specialized hardware or sophisticated software that loosely model the learning and remembering functions of the human brain. They are an attempt to simulate the multiple layers of processing elements in the brain, called neurons. These elements are implemented in such a way so that the layers can learn from prior experience and remember their outputs. In this way, the system can learn to recognize certain patterns and situations and apply these to certain priorities and output appropriate results. These types of neural networks can be used in many important situations such as priority in an emergency room, for financial assistance, and any type of pattern recognition such as handwritten or text-to-speech recognition.
