Cork LUG: Security for the dial-up user [Portsentry review]

"I've been online for years now starting with Windows clients and now Linux runs on my box at home. I never took much notice of security beyond the obvious: install updated software, don't run things as root, and turn off extra services."

"A few weeks ago I chanced upon Portsentry [homepage] which I had looked at about a year previously but never got around to using. To put it simply, Portsentry keeps an eye on who's connecting to your machine. It will take action whenever someone tries to do something they're not allowed do."

"As an example, I installed Portsentry on a Friday night. My machine is online all during the weekend and I went shopping on Saturday for a few hours. When I came back I was greeted with a warning in my log files and an email saying that someone had attempted to telnet to my machine! I was amazed! Since then I've averaged about 2 attacks every weekend. My home machine isn't on some cable network, or hosting a major web site. It's a dial-up connection through a 56k modem."
