mod-evasive

Good day,

I'm running an Apache2 server in front of a Tomcat and I need to implement a DDOS protection mechanism on the Apache2 layer. I have two candidates: mod_evasive and mod_security2 with the OWASP core rule set.

Mod_security is already installed for overall protection, but the question is: is it worth adding mod_evasive besides mod_security just for the DDOS (does it have any major advantages) or the OWASP crs rules in the /experimental_rules/ directory (modsecurity_crs_11_dos_protection.conf) provide the same protection? Or it's just a matter of preference? The sites are not very high traffic normally.

Thank you for your answers, Martynas
