Your handy PC security checklist

If you're in charge of securing end-user systems at your organization, print out this security checklist and put it on standby

In this emerging age of cloud computing, it's easy to remain focused on the server side of the security equation. However, with crafty cyber criminals running rampant and the continued rise of APTs (advanced peristent threats), securing end-user systems remains critical. Hackers and other troublemakers have a variety of ways by which to turn a PC a perfect access point for wreaking havoc, be it via an outsider exploiting an unpatched vulnerability or an insider taking advantage of unncecessarily elevated privileges to swipe valuable information.

For an IT admin, it can be easy to overlook a critical step in making PCs, workstations, and laptops safe. Using this checklist as a guide should prove helpful in tackling the task.
