DEPLOYMENT OF INTRUSION PREVENTION SYSTEM ON MULTI-CORE PROCESSOR BASED SECURITY HARDWARE

With invent of new technologies and devices, Intrusion has become an area of concern because of security issues, in the ever growing area of cyber-attack. An intrusion detection system (IDS) is defined as a device or software application which monitors system or network activities for malicious activities or policy violations. It produces reports to a management station [1]. In this paper we are mainly focused on different IDS concepts based on Host and Network systems.

The nature of wireless networks itself created new vulnerabilities that in the classical wired networks do not exist. This results in an evolutional requirement to implement new sophisticated security mechanism in form of Intrusion Detection and Prevention Systems. This paper deals with security issues of small office and home office wireless networks. The goal of our work is to design and evaluate wireless IDPS with use of packet injection method. Decrease of attacker’s traffic by 95% was observed when compared to attacker’s traffic without deployment of proposed IDPS system.

In emerging technology of Internet, security issues are becoming more challenging. In case of wired LAN it is somewhat in control, but in case of wireless networks due to exponential growth in attacks, it has made difficult to detect such security loopholes. Wireless network security is being addressed using firewalls, encryption techniques and wired IDS (Intrusion Detection System) methods. But the approaches which were used in wired network were not successful in producing effective results for wireless networks. It is so because of features of wireless network such as open medium, dynamic changing topology, cooperative algorithms, lack of centralized monitoring and management point, and lack of a clear line of defense etc. So, there is need for new approach which will efficiently detect intrusion in wireless network. Efficiency can be achieved by implementing distributive, co-operative based, multi-agent IDS. The proposed system supports all these three features. It includes mobile agents for intrusion detection which uses SNMP (Simple network Management Protocol) and MIB (Management Information Base) variables for mobile wireless networks.

This document discusses building an intrusion detection system that combines network-based and log-based detection. It proposes using the Security Onion distribution and its included tools like Snort, Sguil, Squert and OSSEC. It describes configuring Security Onion sensors to monitor network traffic and logs, storing alerts in databases, and using the management consoles to analyze alerts. The goal is to create a comprehensive security monitoring platform through centralized log management and correlation of network and host-based events.

This document discusses network intrusion detection systems (NIDS) and their ability to handle high-speed traffic. It introduces NIDS and their role in monitoring network traffic. The document presents an experiment that tests the open-source NIDS Snort under high-volume traffic. The experiment shows that Snort drops more packets as traffic speed and volume increases, demonstrating a weakness of NIDS in high-speed environments. It suggests using a parallel NIDS technique to help NIDS better handle high-speed network traffic and reduce packet dropping.

This document describes a honeynet framework to promote enterprise network security. The framework consists of two high-interaction honeypot servers connected by a switch to a monitoring station. The honeypots provide real operating systems and services to attract attackers. When an attacker attempts to access a honeypot, its data is captured by a packet sniffer and stored in a database. This data is then sent securely to the monitoring station using web services. The monitoring station analyzes the data, generates an alert report, and provides a GUI to monitor extracted information. The goal is to identify attack traffic and profile attackers to improve network defense.

Whenyour computer isconnected to the Internet, you expose your computer to a variety of potentialthreats. The Internet isdesigned in such a waythat if you have access to the Internet, all other computers on the Internet canconnect to yourcomputer.Thisleavesyouvulnerable to variouscommonattacks. This isespeciallytroubling as severalpopular programs open services on your computer thatallowothers to view files on your computer!

To protectyour computer fromsuchattacksyouneed to "teach" your computer to ignore or resistexternaltestingattempts. The commonname for such a program is Firewall. A firewall is software thatcreates a secureenvironmentwhosefunctionis to block or restrictincoming and outgoing information over a network. These firewalls actually do not work and are not suitable for business premises to maintain information securitywhilesupporting free exchange of ideas. Firewall are becoming more and more sophisticated in the day, and new features are beingadded all the time, sothat, despitecriticism and intimidatingdevelopmentmethods, they are still a powerfuldefense. In thispaper, weread a network firewall thathelps the corporateenvironment and other networks thatwant to exchange information over the network. The firewall protects the flow of trafficthrough the internet and limits the amount of external and internal information and provides the internal user with the illusion of anonymous FTP and www online communications.

Modern information security management best practices dictate that an enterprise assumes full configuration control of end user computer systems (laptops, deskside computers, etc.). The benefit of this explicit control yields lower support costs since there are less variation of machines, operating systems, and applications to provide support on, but more importantly today, dictating specifically what software, hardware, and security configurations exist on an end user's machine can help reduce the occurrence of infection by malicious software significantly. If the data pertaining to end user systems is organized and catalogued as part of normal information security logging activities, an extended picture of what the end system actually is may be available to the investigator at a moment's notice to enhance incident response and mitigation. The purpose of this research is to provide a way of cataloguing this data by using and augmenting existing tools and open source software deployed in an enterprise network.
