Hello Enhance & Community,
An intrusion detection and protection suite would help a lot since my own web server became an attack source out of nowhere (it was not on Enhance), it wasn't in use as well.
We can take a inspiration from Plesk's Juggernaut Security and Firewall addon.
A Intrusion detection and protection software is necessary in this modern time to mitigate threats, Enhance currently has ModSecurity for WAF and Bruteforce protection for DDoS and rate limiting, an IDS and IPS system would cover the protection on Web Server side.
Cordially,
Oryon
