Improved Snort Intrusion Detection System Using Modified Pattern Matching Technique
As the number of network attacks rise, the need for security measures such as Intrusion Detection Systems (IDS) is essential. IDS's are considered useful especially when new community hacking tools are emerging. Intrusion detection system identifies problems with security policies, documenting existing threats and detects individuals that violate the security policy. Due to the limitations of the firewall and Intrusion Detection System in the information security domain Intrusion Prevention System (IPS) appeared. It is a new generation information security technology following the firewall and intrusion detection technique.
