My Top Postings of 2010
Well, now that 2010 is over I would like to go back and look at my top 3 postings based on Google Analytics. I’m really not much of a writer as I’m sure you can tell from my postings, but I do want to be able to share whatever knowledge I have and I do hope this blog helps with that. I would love to hear from people that pop on to the site from a search and found some helpful info.
Stopping SSH Brute Force attacks with PF on FreeBSD
Most people know that port 22 is used for SSH communication and due to this common knowledge, you get people using scripts to test for weak passwords. If you look into your /var/log/auth.log and you see tons of fails/errors from users not on your system or from invalid passwords for root, it means you have people trying to break into your system. Truthfully, anyone that puts a system online with port 22 open will see this happen to them.
