Touchdown Task for November- Network Segmentation Review

Whether it is budget preparation or annual project planning, the end of the year always leads us to think of the “big picture”. The touchdown task for this month is to review your network architecture maps and diagrams. First of all, make sure they are up-to-date. But secondly, look for indications that your network might be too flat. That is, do you have proper network segmentation between all of your information resources? Are your firewalls placed properly throughout your environment? 


A “flat” network architecture allows attackers who have gained a foothold on the internal (and sometimes even the external — you do have a layered DMZ, right?) network full visibility to internal systems and to move freely through workstation and server space. 


If you see some re-architecting that should be done, make note of it now. Depending on the complexity of the work, either schedule the re-architecture for a slow period at the end of this year or create a work plan for 2014. 

As always, thanks for reading and keep your eyes on the goal!
