XP End of an Era or... Deja Vu All Over Again!

   Unless you just came back from time traveling, you know that Microsoft is ending support for the XP
operating system on April 8.  To be clear... April 8 is Patch Tuesday, so that will be the last set of updates for XP.  Sort of.

   XP has been one of Microsoft's most popular desktop operating systems and many organizations are dependent upon it.  Many organizations have not yet updated to Windows 7 or 8 and the clock is ticking.  I'd like to look at what that means and share a few ideas of what we can do to protect ourselves and our organizations.

   Microsoft will be stopping all patches, hotfixes and enhancements to XP after April 8.  Anti-virus signatures will continue to be made available.  This means that any vulnerabilities that are discovered or disclosed might not be fixed.  Organizations will need to figure out if they are vulnerable to any new threats and then weigh the risks associated with their options.

   There has been some speculation that online criminal organizations may be stocking up on new vulnerabilities so these can be released after the last patch date.  We can't know if this is true, but it is possible.

   So... if you are still running XP, and need to continue to run XP, what can you do?  Let's do a high-level threat analysis:

Online Self Defense - Your Computer

   It's Cyber Security Month!  And the more things change, the more they stay the same.  The key advice for online self-defense I've given in the past is just as true now.  So to help us all celebrate, I'm "re-featuring" a few articles I've run in the past.



   Happy US Cyber Security Month!  This partnership between Homeland Security, NCSA and MS-ISAC is an opportunity to recognize the importance of information security.  How are you celebrating?

   Last week I ran a couple of sessions at work on awareness and security.  Over the next few posts I will be reviewing some of the 3 themes I covered in a talk entitled "Online Self-Defense". You can view the slides on my slideshare page. (actually, the talk focuses on just 2 of the themes but that's OK!). Since everything comes in threes (omne trium perfectum), I will give 3 easy tips for each theme (and some bonus tips as well).

   The first theme is protecting your computer or device.
