Working with more than 1000 organizations across the globe allows us to gain some interesting perspectives from customers when it comes to network security tips. There has been plenty of discussion on the status of the firewall in today’s network environment, but the fact remains that firewalls continue to serve as a primary layer of defense for preventing malicious traffic. But as firewall capabilities have evolved, so too have other network security technologies, processes, frameworks, architectures, etc. that all play a role in the success/failure of your security program. With that said, I’d like to introduce our “Network Security Tip of the Week”. We’ll share a new tip once a week collected from security professionals from our customers and partners, as well as our own employees. Only first names will be used for confidentiality purposes.
I hope you enjoy these and if you have your own tip to share, please either comment on this blog or Direct Message us the tip on Twitter via @AlgoSec. And now for the first Network Security Tip of the Week…
“One of the things people like to do the least is also one of the most useful things they can do and that is to DOCUMENT the changes they make to a system. With firewalls, it is especially critical for people to document the rules they add or change so that other administrators know the purpose of each rule and who to contact about them. Trying to troubleshoot an issue with a firewall that has scores of undocumented rules can be very frustrating. Good documentation can make troubleshooting easy and reduces the risk of service disruptions that can be caused when an administrator deletes or changes a rule they do not understand.”
