Security software on Microsoft Windows 8.1

With the explosion of zero-day exploits, vendors are rushing to patch critical vulnerabilities.  In my opinion, this does not allow time for complete regression testing against the wide variety of applications and hardware.  Since broken and non-booting machines can be difficult to fix in a reasonable time frame, I now recommend installation of Microsoft patches not on patch Tuesday but a day or two later - after the patches have been tested by other users. 

For home use, I run the following free security products on Microsoft Windows 8.1:

BlackBerry Smartphone - One Month Impressions

While this model is a couple years old, I am thoroughly enjoying the BlackBerry Z10.

The BlackBerry Hub integrates all forms of communication onto one page.   This is surprisingly useful, and I won't go back to previous checking of this and that ... calls and  voicemails and texts and emails.  Multiple email accounts + text + calls + voicemail + notifications all on one page, and I can specify the order of priority.  This one feature makes the BlackBerry a real business communicator.

BlackBerry native apps allow the user to control app permissions such as access to files, camera, contacts, etc.  This level of permission control greatly enhances user privacy - no longer do we have to accept apps that pick every possible permission.

Android apps run fine.  I am currently using the Amazon app store, and have not tried sideloading apps.

Battery performance seems reasonable.

There are a few annoyances:
Mini-USB plugs in to the left side of the phone.  The swipe to see the BlackBerry Hub swipes in from the left side, so when plugged in the cord can interfere with the swipe.

The built-in camera app has no ability to disable shutter sound.  Supposedly this has something to do with Canadian law.  A 3rd party camera app could be installed.

For Android apps, it does not allow user to over-ride the app permissions, as it does with BlackBerry apps.  Permission control on Android apps is a much-desired feature.

Microsoft Enhanced Mitigation Experience Toolkit

Earlier this year I installed Microsoft's Enhanced Mitigation Experience Toolkit (EMET) version 3.  The Microsoft blog describes EMT as... "a free utility that helps prevent vulnerabilities in software from being successfully exploited for code execution. It does so by opt-ing in software to the latest security mitigation technologies. The result is that a wide variety of software is made significantly more resistant to exploitation – even against zero day vulnerabilities and vulnerabilities for which an update has not yet been applied."

I'm not sure why "Experience" is in the name of the product.  EMET helps prevent bug exploits by forcing application address space layout randomization and data execution prevention in addition.

With the recent Microsoft zero-day patches, I learned that EMET is up to version 5.  The latest versions add compatibility fixes and additional security protections.

Download the Enhanced Mitigation Experience Toolkit 5.  For those uninstalling a previous version, go to the Programs page in Control Panel and look for "EMET".
