How insecure is your PC?

Frequent readers of Red Gecko have seen my posts about keeping your home PCs secure so they don't become zombies as part of some huge botnet. With the threat landscape constantly evolving, it's tough to keep up with all the insecure software that might reside on your home box.

You've also read my recommendations for a free tool called Secunia PSI that runs in the background and reminds you of things like missing patches, insecure programs, and end-of-life products that probably no longer have security support at all, so running them is a bad idea.

Secunia has posted a nice little survey based on results they've noted from loaded machines reporting back their scanning results. Not sure I like that, but it's a trade off to consider...having a program keep you current while recording users issues for analysis and publication.

Anyway, here's a snippet from their results:

Number of insecure programs per PC/user:
0 Insecure Programs:	1.91% of PCs
1-5 Insecure Programs:	30.27% of PCs
6-10 Insecure Programs:	25.07% of PCs
11+ Insecure Programs:	45.76% of PCs

98% of PCs surveyed had at least one outdated program. If you keep in mind that each insecure or end of life piece of software increases your risk, you can see that having 11+ instances of this is a lot like leaving your doors and windows open and trusting the bad guys to either not notice or pass you by for the house down the street. Eventually, your number will come up.

Just some info for you to chew on.
