For my very first article for Canada Computes I reviewed Port Sentry and I felt it was worth touching on again since I would consider it essential for any Linux machine with an Internet connection, particularly after reading about the above mentioned 280% increase in probes. The program effectively stands guard over your system and logs any attempted intrusions. This includes things like attempted connections, portscans perpetrated by programs which are designed to sniff around to see if you have any "open doors" on your machine, and what that door is. Portsentry, in the event of finding this activity, drops the connection so the system at the other end can't connect again. It's a simple little program but it works exceptionally well and every friend I've pointed to it has thanked me.
