For now lets get started: Step 1: Installing on Ubuntu (tested on 14.04) but will likely work on any version:Įnsure you are getting logs from your IPTables. More information is available at the source. Getting Started with PSAD on Ubuntu Linuxīasically psad is a perl based daemon that monitors the output of iptables logging. You could also send PSAD logs to OSSEC and create some rules to generate alerts, but the native PSAD email alerting and configuration is simple and straightforward to get up and running quickly. The PSAD scripts parse the logs to find relevant information and creates simple reports.Īnother alternative tool for defenders is the OSSEC, this host based tool could also be configured to read the firewall logs and parse out results into alerts. The syslog messages are generated by IPTables firewall logging. This is the method used for many Intrusion Detection Systems. How PSAD detects attacks?ĭetecting port scans can accomplished by sniffing packets off the wire. As is often the case a simple open source tool can provide a great deal of detail about attackers. In this short tutorial I will show you how to quickly get a port scan monitoring system in place.
