DEVELOPMENT OF AN INTRUSION DETECTION SYSTEM IN A COMPUTER NETWORK (original) (raw)
Related papers
The development of network technologies and application has promoted network attack both in number and severity. The last few years have seen a dramatic increase in the number of attacks, hence, intrusion detection has become the mainstream of information assurance. A computer network system should provide confidentiality, integrity and assurance against denial of service. While firewalls do provide some protection, they do not provide full protection. This is because not all access to the network occurs through the firewall. This is why firewalls need to be complemented by an intrusion detection system (IDS).An IDS does not usually take preventive measures when an attack is detected; it is a reactive rather than proactive agent. It plays the role of an informant rather than a police officer. In this research, an intrusion detection system that can be used to deny illegitimate access to some operations was developed. The IDS also controls the kind of operations performed by users (i.e. clients) on the network. However, unlike other methods, this requires no encryption or cryptographic processing on a per-packet basis. Instead, it scans the various messages sent on a network by the user. The system was developed using MicrosoftVisual Basic.
USE OF FIREWALL AND IDS TO DETECT AND PREVENT NETWORK ATTACKS
Due to tremendous growth of usage of computer and Internet, the human has entered into an era where there is huge amount of information which is valuable and this information enter into their life via internet. No doubt that this kind of information, makes people's life faster and more convenient; on the other hand, various kinds of harmful contents are flooding the Internet, such as viruses, junk mails and so on, which do great harm not only to the individual but also to the whole society. Firewalls and intrusion detection systems are two most famous and important tools that are used to provide security. Firewall acts as first line of Defense against network attacks .They monitor network traffic in order to prevent unauthorized access. Although firewall can control network traffic but they cannot be entirely depended to provide security. Intrusion detection system (IDS) reduces security gaps and strengthens security of a network by analyzing the network assets for anomalous behavior and misuse.. Real time detection with prevention by Intrusion Detection and Prevention Systems (IDPS) takes the network security to an advanced level by protecting the network against mischievous activities .In this Paper, we illustrate two important network security tools which includes firewalls and intrusion detection systems their classifications, shortcomings as well as their importance in network security.
IDS : Intrusion Detection System the Survey of Information Security
2012
With the increased use of computerized / online transactions it is very much of the importance to secure the information from intruders. Intrusion detection is the process of monitoring the activities or events occurring in the computer system or network and analyzing them to find out suspicious events intruding the system or network. Such events will be reported to the administrator of Intrusion Detection System(IDS) who will decide the further action. This Paper surveys different types of IDS and lists preventive methods.An intrusion detection system (IDS) is software that automates the intrusion detection process. An intrusion prevention system (IPS) is software that has all the capabilities of an intrusion detection system and can also attempt to stop possible incidents.

Analysis of intrusion detection and prevention systems
International Journal of Advanced Academic Studies
Recently, the security of an individual computer to large networks as a result of a dramatic growth of new devices connecting to the internet, has become one of the biggest challenges. Along with growing new types of security attacks, many protection mechanisms have taken to improve the privacy and security of sensitive information. Detection of abnormal behavior can help network administrators to identify intrusions but cannot prevent them from breaking into home network. Furthermore, using traditional methods which firewall and IDPS systems reside in different machines that results to low performance by filtering and checking traffic in multi points. This paper is providing an efficient and cost effective method of both detecting and preventing network threats. To achieve such goal, we are using a form Snort, Suricata, and Bro IDPS Systems.
INTRUSION DETECTION SYSTEM – A STUDY
Intrusion Detection System (IDS) is meant to be a software application which monitors the network or system activities and finds if any malicious operations occur. Tremendous growth and usage of internet raises concerns about how to protect and communicate the digital information in a safe manner. Nowadays, hackers use different types of attacks for getting the valuable information. Many intrusion detection techniques, methods and algorithms help to detect these attacks. This main objective of this paper is to provide a complete study about the definition of intrusion detection, history, life cycle, types of intrusion detection methods, types of attacks, different tools and techniques, research needs, challenges and applications.

Security is an important and serious issue for every type of network. Many network environments specially those where computers are used as nodes are prone to an increasing number of security threats in the form of Trojan worm attacks and viruses that can damage the computer systems, servers and communication channels. Though Firewalls are used as a necessary security measure in a network environment but still different types of security issues keep on arising. In order to further strengthen the network from intruders, the concept of intrusion detection system (IDS) and intrusion prevention system (IPS) is gaining popularity. IDS is a process of monitoring the events occurring in a computer system or network and analyzing them for sign of possible incident which are violations or imminent threats of violations of computer security policies or standard security policies. intrusion prevention system (IPS) is a process of performing intrusion detection and attempting to stop detected possible incidents. This study aims to identify different types of Intrusion Detection and Prevention techniques discussed in the literature.
Abstract— The main goal of IDS (Intrusion detection Systems) is attack detection whether the subject to attack was a single computer or an entire network. Despite the major effort to provide a more security to Information systems , and keeping it as safe as possible, it is not possible to provide fully secure These systems , in addition to the fact that even a truly secure system is vulnerable to abuse by insiders who abuse their privileges . Therefore, there is a massive need for the existence of intrusion detection systems performing constant monitoring to the system traffic and efficiently detect any apparition of intrusion attempts whether it came from inside or outside the network .

Intrusion Detection & Preventing Systems
The tremendous increase in cyber-attacks linked with the dependence of modern organization on the reliability and functionality of their IT structure has led to a change in mindset. Network security components like Firewalls, Anti-Virus programs and pure Intrusion Detection Systems (IDS) cannot handle wide range of malicious attacks and zero day exploits on computer networks and systems. Hackers, multi-exploit worms, Trojan horses, and polymorphic viruses are penetrating those traditional defenses, causing billions of financial loss to businesses as well as publishing very sensitive critical information to general public which is even worse than financial losses. Intrusion Detection and Prevention Systems (IDPS) have emerged as one of the most effective ways of providing reliable security to those connected to the networks. IDPS are mainly focused on identifying possible threats, logging information about them, attempting to stop them, and reporting them relevant parties. IDPSs can be used to other purposes, like identifying problems with organization's security policies, documenting existing threats, and deterring individuals from violating security policies. Now days having an IDPS have become priority to the security infrastructure of almost every organization.
A Comparative Study of Related Technologies of Intrusion Detection & Prevention Systems
Journal of information security, 2011
The rapid growth of computer networks has changed the prospect of network security. An easy accessibility condition causes computer networks to be vulnerable against numerous and potentially devastating threats from hackers. Up to the moment, researchers have developed Intrusion Detection Systems (IDS) capable of detecting attacks in several available environments. A boundlessness of methods for misuse detection as well as anomaly detection has been applied. Intrusion Prevention Systems (IPS) evolved after that to resolve ambiguities in passive network monitoring by placing detection systems on the line of attack. IPS in other words is IDS that are able to give prevention commands to firewalls and access control changes to routers. IPS can be seen as an improvement upon firewall technologies. It can make access control decisions based on application content, rather than IP address or ports as traditional firewalls do. The next innovation is the combination of IDS and IPS known as Intrusion Detection and Prevention Systems (IDPS) capable of detecting and preventing attacks from happening. This paper presents an overview of IDPS followed by their classifications and applications. A new signature based IDPS architecture named HawkEye Solutions has been proposed by the authors. Authors have presented the basic building blocks of the IDS, which include mechanisms for carrying out TCP port scans, Traceroute scan, ping scan and packet sniffing to monitor network health detect various types of attacks. Real time implementation results of the system have been presented. Finally a comparative analysis of various existing IDS/IPS solutions with HawkEye Solutions emphasizes its significance.
