[BALUG-Talk] Servers and security

[Kim Davalos]

Curious about what folks due to harden/secure their servers. 
Specifically I am NOT asking to be told what to do/how to do it.

More interested in hearing about different practices and approaches, 
e.g., firewall management - iptables/nftables vs something like Check 
Point, limiting installed packages to what is necessary, closing unused 
ports, access restrictions, etc.

Best would be vigorous debate and disagreement.
