In my last post, we covered the basic concepts of cloud computing. This time, we’ll be diving down a little deeper into the cloud to cover the actual structure that most cloud environments use to operate. There are a lot of differences between cloud providers, but they all use very similar hardware and network designs to get things done.…

How to solve problems with Exchange Autodiscover. Certificate Error issues in particular.

Based on my experience with organizations of all sizes I can say with a good bit of authority that almost every Exchange organization out there is probably vulnerable to this attack.…
As I mentioned in an earlier post, email encryption is a sticky thing. In a perfect world, everyone would have Opportunistic TLS enabled and all mail traffic would be automatically encrypted with STARTTLS encryption, which is a fantastic method of ensuring security of messages “in transit”. But some messages need to be encrypted “at rest” due to security policies or regulations.…
I’ve decided to start a short series of posts on data encryption, which is becoming an increasingly important subject in IT as government regulations and privacy concerns demand ever increasing levels of privacy and security.
In this series, I’ll try to cover the more confusing concepts in encryption, including the three main types of encryption systems used today; Private Key encryption, Public Key Encryption, and SSL/TLS encryption.…
IT people, for some reason, seem to have an affinity towards designing solutions that use “cool” features, even when those features aren’t really necessary. This tendency sometimes leads to good solutions, but a lot of times it ends up creating solutions that fall short of requirements or leave IT infrastructure with significant short-comings in any number of areas.…
