How do you handle server security/intrusion monitoring?
aschobel: FreeBSD handbook goes over some practices, treat security like layers of an onion peel.http://www.freebsd.org/doc/en/books/handbook/security-intro....Some things we found useful* don't have ssh bind to a public interface on. You need to VPN in first and then ssh to the private IP. we only have 80 and 443 open on public interfaces* portaudit is awesome. it keeps you up to date if there is an exploit for software that you run, not just "is there an update". portaudit will tell you if there is an unpatched vulnerability out there so you can make a decision on what to do.* paranoia - don't trust anything. we run WP on a DMZed box that doesn't have access to anything. we mod_proxy all requests to this box from our edge servers. jails are also great for this, give everything the least amount of permissions necessary to run* monitor your servers, any weird cpu usage or bw. cacti is quite niceYou can also block all outbound traffic on your serves that isn't responding to a requests.
