RedAlert: Approach for Firewall Policies Update Mechanism

RedAlert is a system created with the integration of existing systems to create a dynamic and effective mechanism of tackling the problem of intrusion and security. The system is able to react automatically based on the information received from the stored database. Commencing with the information and data received from the system, RedAlert will react by producing a new network policy. This will block intruders who attempt to formulate a break-in by dynamically changing the firewall policy. The usage of multicast, unicast and other technologies from open source protocols such as iptables and Snort will be used to explain this new approach. This paper discusses the approach taken and the obtained research results. Key-words: Intrusion detection system, firewall policies update, multicast.
