Why nobody cares about Network Neutrality.

In the circles I run in, you can’t go 15 minutes into a conversation without someone bring up Network Neutrality. In my world, it’s a huge deal. And, in my world, there are people on both sides of the issue. If you don’t know what Network Neutrality is, then just pop open your favorite search engine, and type in ‘network neutrality’. You’ll find tons of articles and videos about the subject. All of them asking you to write your elected official, or sign a digital petition. The problem is, for the most part, no one really cares. Sure, there’s a small group of technology people that consider Network Neutrality as one of the most pressing issues of our age, but for the most part, regular folks aren’t getting the message. With so much info available about Network Neutrality from both sides of the issue, you would think people would be all over it.

Signs of a failing Hard Drive.

Do you know what piece of computer hardware is the most likely component to fail? If you answered the hard drive, you’re absolutely correct! Why? It’s one of the few moving parts left in a computer. With a hard drive, it’s not if it will fail, it’s when!

So, we know it’s going to fail. What can we do to:

• Protect our data from loss.
• Predict when a hard drive will fail.

Heartbleed – What is it? (for non geeks)

The Heartbleed bug was caused by a programming error in a software package called OpenSSL. This error had the potential of allowing bad people to attach to secure web and email servers, as well as services that rely on the TLS/SSL protocol, and steal the private encryption key off the servers. The TLS/SSL protocol is what puts the pretty little lock in the address bar in your browser. The private key is what the owners of the sites you go to are suppose to keep secret, and not share with anyone because if someone has it, they can decrypt the encrypted data traveling between your system and the server. THIS IS BAD…

Heartbleed – What is it? (for geeks)

The Heartbleed bug was caused by a programming error in the OpenSSL library that deals with TLS handshakes. A couple years back, a new RFC (rfc 6520) proposed a new extension to the TLS protocol that would allow a heartbeat to be exchanged between the client and server to reduce the number of re-negotiations during a TLS session. This all sounds good, and actually is a very beneficial to the protocol in general, but when it was implemented in OpenSSL, an error in the way the code was written allowed a request to grab a bunch of data without checking the boundaries of the data itself. This could allow someone to make a request crafted in a certain way that would cause OpenSSL to return 64k of protected memory data possibly containing the SSL private key of the server.

We have received reports that the CryptoLocker ransom-ware is becoming more prolific every day.

CryptoLocker ransom-ware is a malware program that when ran, will search all connected drives on your Windows PC, and then using strong public/private key encryption, proceeds to encrypt all of your data files it can find.

What it does:

Once it is done encrypting all the data files it can find, it will delete the private portion of the encryption key, and present the user with a popup. This popup informs the user that they have been infected and must pay $300 dollars via Bitcoin to receive the key to regain access to the data.

Samba 4 as an Active Directory Server – Can it dance the dance?

Two weeks ago I thought to myself ‘Gee, now that Samba 4 has a real release out, wouldn’t it be fun to test it out and see how it holds up?‘ And so my adventure began. Now mind you, I’m not a novice to Samba, or to Active Directory, so I figured this would be a simple setup and test. How hard could it be?
