We hear and read about the necessity of keeping law firm computers (and the confidential client information they contain) secure from malicious software and hackers, but not all of these efforts are created equal. The number one way to keep your computers secure is to keep all the software in those computers patched.
By patched, I don’t mean just Windows and other Microsoft products. In fact, those account for just a tiny fraction of security problems today. The biggest culprits—and this surprised me as well—Java and Adobe Acrobat Reader. Those two account for 78% of the malicious intrusions by hackers today according to InfoWorld.
So it is important to make sure you are allowing automatic security patches into your computers for Windows and your web browsers, and that you check for updates for your other software including Adobe Reader and Flash Player. or that you have software like Secunia PSI (or Small Business version) to help you keep all software on your computers promptly patched when security holes are discovered.
This does not mean you have to forget about your other regular security precautions, but making sure your computers a patched will help you sleep better at night.
