One of the secrets of the security industry is that a lot of great tools don't cost money. It's a secret because nobody pays for advertising for free tools.

via Watchguard, Tech Republic lists ten free security tools. They must have put in some real research, since they came up with some I hadn't heard of.

They list the NoScript extension for Firefox, which just gets more necessary every day. Another highlight is Secunia's Personal Software Inspector, which does an inventory and tells you what needs updating.
