Heartbleed: What You Need To Do

Most of us have heard the news about the "Heartbleed" vulnerability, which possibly allows hackers to retrieve your login password or other personal information from many popular web sites. So what's it all about?

"Heartbleed" refers to a vulnerability in an encryption library that's used by many different web servers. The library is called "OpenSSL," and it's what's used to make online commerce, banking and other activities secure. OpenSSL is not the only encryption library available, but it's one of the most popular.

SSL Vulnerability Closed in OS X Update

Apple released Security Update 2014-001 yesterday, which closes the vulnerability discussed in my last post. Mountain Lion and Mavericks users should install this update ASAP. Note, if you are a Mountain Lion user and do not wish to update to Mavericks at this time (completely understandable, but fixable), then do not install the OS X 10.9.2 update. Select just the Software Update that includes Security Update 2014-001 as shown in the screenshot below.

OSX Software Update

The vulnerability allows your secure traffic to services such as iCloud, Gmail, and others to be intercepted. For specific details of this vulnerability, please consult the excellent writeups in ArsTechnica, The Safe Mac and Threatpost. If you haven't updated your iPhone or iPad to iOS 7.0.6, please do so now to fix the same vulnerability in iOS.

What's the deal? A very serious vulnerability that exposes the secure communication link between your device and any services that you use (Gmail, Facebook, Dropbox, online banking, etc).

The exploit package is already being circulated on the Internet. This vulnerability affects not only iOS, but also OS X. Apple has not patched OS X yet, so stay tuned here. I'll post when Apple releases the update for your Mac.

If you'd like to read the technical details of this vulnerability, read this and this. But first, please update your devices!

Cloud for Small Business - Hot or Not? Redux (UPDATE 2/24/14)

Google Apps. Microsoft Office 365. What are they and why do we care?

Interesting questions. What does every modern office need? A productivity suite to create and edit documents, spreadsheets and presentations. A messaging system, for sending email and enabling chat. A calendaring system, to facilitate time management and shared scheduling. A collaboration system, to corral projects, tasks, data and team members.

The classic solutions consists of the Microsoft Office productivity suite, Exchange Server for email and calendaring, and Sharepoint Server for collaboration. Why would we consider anything else?
