OOAC, LLC implemented linux firewall for one of its clients to provide perimeter security. Shorewall was used as the firewall to check on traffic in and out. This ensured quality of service and involved multiple security zones. Delimiter zones with access control was used. Snort, an open source NIPS(Network Intrusion Prevention System) and NIDS(Network Intrusion Detection System) was used for real time traffic analysis and packet logging on the IP networks. It inspects malicious users and contains built in signatures. To complement this HID was installed on all servers. Agent was installed to monitor all activities, deletion, installation, registers and OS in order to track any breakdown and take proactive actions.
