The debate on encryption has heated up significantly in the last couple of months. Most of the recent discussion has revolved around a particular device in a specific case but encryption is older than that. Modern encryption systems represent the culmination of centuries of development of making sure things aren’t seen.
Did you know that twenty years ago the U.S. Government classified encryption as a munition? Data encryption was classified as a military asset and placed on the U.S. Munitions List as an auxiliary asset. The control of encryption as a military asset meant that exporting strong encryption to foreign countries was against the law. For a number of years the only thing that could be exported without fear of legal impact was regular old Data Encryption Standard (DES) methods. Even 3DES, which is theoretically much stronger but practically not much better than it’s older counterpart, was restricted for export to foreign countries.
While the rules around encryption export have been relaxed since the early 2000s, there are still some restrictions in place. Those rules are for countries that are on U.S. Government watch lists for terror states or governments deemed “rogue” states. Continue reading

As more parts of IT become "software-defined," be sure you're asking the right questions.

Usman asked a few questions in his comment on my blog, including:
At the moment, local RIB gets downloaded to FIB and we get packet forwarding on a router. If we start evaluating too many fields (PBR) and (assume) are able to push these policies to the FIB - what would become of the FIB table size?
Short answer: It would explode ;)
Read more ...Building a strong network of people is very important in creating a successful career in IT. In these posts we will start first look at why building a network is important and in the other posts we will look at how to actually build the network and how to make sure that you are also contributing to the network and not only exploiting it.
If you came here to read about connecting cables or routing protocols, sorry, this is not that kind of post. This post is about how to build a network of people.
People often understimate the power of having a big reach in the industry through a network of people. I often hear in my role that I’m almost too effective sometimes. Part of that is because I have a very good network of people that I trust and rely on. In this blog we will look at WHY you want to build a network of people.

I was recently asked to automate the way a client handles Cisco IOS upgrades. As I’ve been using Ansible a lot lately I decided to start there. Basically the steps required to do the upgrade can be broken down into parts which map quite nicely to tasks in an Ansible playbook. Even if you aren’t using IOS you might find it interesting to see how different Ansible modules can be combined in order to complete a set of tasks.
