Setting up Tripwire

Written by

tripwire --check

I was doing some research for my firewall project that I wrote about the other day and wanted to add some system monitoring.

Last week was the 6th annual Army Cyber Skills Challenge (ACSC) hosted by my home unit, 780th MI Brigade.  If you don’t recall, I first wrote about ACSC about this time last year.  This was the 2nd year in a row that I served as the OIC for the event, and it was truly bigger »
