Hi folks, more often than not I see people deploying new network equipment or servers without firmware updates. What’s up with that?

As a good best practice it only makes sense to update the firmware on devices. These firmware updates usually patch lots of security holes and other bugs. People tend to be quite religious about doing windows updates but then forget about doing firmware updates to their network hardware.

Believe it or not, doing firmware updates to your firewall or switch can save you in the long run from some sort of crazy exploit. You should always keep up to date on the latest updates in firmware available for your equipment and adopt a policy to keep these devices up to date.

If you have devices that can’t go down due to firmware updates then it’s important to architect your network so it’s redundant so these firmware updates can still happen regularly.
