I am working on setting up new networking for datacenter hosting a web site.
We have following topology
Internet -> Firewall1 -> ReverseProxy(for security) -> Web Server -> firewall2 -> databse
Firewall is linux iptables hardened
We do not have any IPS or IDS in here.
Question is Is ips/ids required for web server hosting? does it gain anything? only ports that are open is 80 and 443
