Hey everyone,
I’ve been working on securing our network infrastructure and the concept of network firewall protection keeps coming up as a critical piece. I understand the basics — filtering traffic, blocking malicious IPs, segmenting internal versus external access — but I’m trying to figure out what makes a firewall setup truly effective in the real world.
I’d really like to hear about your experiences. How have you chosen which firewall hardware or software to use? What has worked for you when it comes to rule configuration so that you don’t accidentally block legitimate traffic while still keeping threats out? Also, how do you maintain and audit firewall rules over time so they don’t become outdated, overly permissive, or contradictory?
If you’ve had to respond to a security incident, how did your firewall protection hold up, and what changes did you make afterward? Any tools, logs, or monitoring techniques you’ve found useful would be great to know.
Looking forward to learning what works (and what doesn’t).
