Using outdated systems
The single easiest way for a hacker to get into a system is to slip in through a hole in your security. The way holes get there is when you use outdated software.
Several hacks in recent years have started when hackers found one computer at a company running old software and were able to break in. Once one computer falls, the rest go like dominoes.
That means keeping Windows, Office and Internet Explorer updated with the latest security fixes. Click here to learn how.
Then it goes without saying - but I'm going to say it anyway - that if you're using computers with Windows XP or Office XP, stop right away. It has too many security holes to be safe in a business environment. It's time to upgrade to Windows 7 or 8, and newer versions of Office.

Be sure to designate either yourself or someone else in your company to man the security threat "crow's nest." Keep an eye out for security updates, reports of email viruses and any other number of threats to your company. My Daily News newsletter is a good place to check.
