Event Analysis Training – “Could you look at some odd IRC Connections?”
July 29, 2009<p>At one of the research sites that we monitor, an analyst noted that a few servers were consistently making a large number of IRC connections. These connections occurred in a periodic manner and appeared to be automated. This blog entry describes the various steps taken in analyzing the connections and historical data. We used Tenable’s log analysis, network monitoring and passive profiling solutions to perform this analysis, but the principals could be applied to various SIMs, NBADs and analytical tools.</p><p> </p>
