INTRUSION DETECTION SYSTEM AND IT’S IMPORTANCE TO THE SOCIETY

Intrusion detection encompasses a range of security techniques designed to detect (and report) malicious system and network activity or to record evidence of intrusion. To understand intrusion detection one must fully understand what intrusion is. For the purpose of this seminar, i define intrusion as any unauthorized system or network activity on one (or more) computer(s) or network(s). This could be an instance of a legitimate user of a system trying to escalate his privileges so that he can gain greater access to the system that he is currently assigned, or a legitimate user trying to connect to a remote port of a server to which he is not authorized.
