mex here, inital creator of http://spike.nginx-goodies.com/rules/
and maintainer of Doxi-Rules
(this us where the rules live we create with spike :)
the doxi-rules in its current state are inspired by emerging threats rules,
and not by the CRS-System because:
- mod_security can hook into any phase of a request, while naxsi only works
- naxsi has a very slim but yet powerfull core-ruleset
- naxsi doesnt hold state of an actor
thus, it would not be possible to re-create the CRS onto naxsi, instead, we
have a very slim but very fast core-ruleset that does not change very often,
and ontop of this, if wanted a wider ruleset that protect against common
classes of attacks like XXE or generel Object-Injections
i learned from my gurus @emerging threats ti write signatures
against vulnerabilities, not exploits
before naxsi i used mod_security with CRS as well and it was
more tha just PITA becaause of False Positives and performance-issues
as well. with naxsdi, learning mode and whitelist-creation
using a WAF is fun again.
