What is an SO rule in the context of Snort?

SO (Shared Object) rules are dynamic plugin modules, typically written in C and compiled as shared libraries, that provide Snort with advanced detection capabilities beyond what standard text-based rules can offer.

SO rules are generally developed in C and compiled into shared libraries, not written in the Perl programming language.

''Simple object'' is not a recognized term or classification for rule types within the Snort intrusion detection system.

''Snort overflow'' is not a type of rule; it might refer to an attack that Snort can detect, but not a rule classification itself.
