We’ve mentioned sysdig several times before, but we haven’t published anything in our English-language blog about the program itself. Today, we’ll be pulling an article out of our archives and looking at our original review of sysdig. Read more
In May 2016, the developers of Sysdig released Falco, a tool for detecting anomalous system behavior.
Falco consists of two main components: the sysdig_probe kernel module (which Sysdig also runs on) and the daemon for writing the information it collects to the disk.
Falco tracks applications according to user-defined rules, and if any anomalies are detected, it writes the information to a standard output, syslog, or user-defined file. in their blog, the developers jokingly call Falco “…a hybrid of snort, ossec and strace,” and position it as a simple IDS that puts almost no additional load on the system.
