Abstract:
Now day’s security is the primary concerned in
the field of computer science.With quickly growing
unauthorized activities in network Intrusion Detection
as a part of defense is extremely necessary because
traditional firewall techniques cannot provide
complete protection against intrusion.The primary
goal of an Intrusion Detection System (IDS) is to
identify intruders and differentiate anomalous
network activity from normal one. Intrusion detection
has become a significant component of network
security administration due to the enormous number
of attacks persistently threaten our computer networks
and systems.This paper illustrates the benefit of
hybrid intrusion detection system that can detect both
known and unknown attacks. The system includes two
phases: (1) If the attack is known attack then signature
intrusion detection handles and performs appropriate
action. (2)If the attack is unknown attack then
anomaly intrusion detection use frequent pattern
matching process and generate the signature that can
handle the next attack. Our proposed system may be
more accurate and better performance than traditional
intrusion detection system.
