Implementation of Genetic Algorithm on Intrusion Detection System to Enhance Result

An Intruder is a hacker or cracker which always tries to get access to secure, system Intrusion occurs when an unauthorized person try to gain access or interrupt the normal operations of an information system. Even when such attacks ar e self-propagating, as in the case o f worms, Trojan Horses and denial-of service attacks, they are almost always initiated by an individual whose purpose is to harm an organizational data. Intrusion detection consists of procedures for detection of illeg al activity of system that identify the intruders. Some important Intrusion Prevention activities are writing and implementing good activity information security rule, planning and performing effective information security instructions, implementing and testing information security system for counting intruders activities like firewalls and IDS and IPS. In Information security Intrusion Detection Systems (IDS) works like a burglar alarm in that it detects destruction and activates an alarm. Recently new technology for IDS systems is the Intrusion Prevention System (IPS), which can detect an intrusion and also prevent that intrusion from attacking the organization. There is a system called Intrusion Detection/Prevention System (IDPS).Recently SNORT is a very useful tool for Network Based Intrusion Detection. A SNORT is tool which can give alert/alarm to the authentic user or Network Administrator by sending email or giving alarm for illegal network activities .
