Writing Your Own Preprocessor

Table of contents:


None of these preprocessors do what I want. How do I write my own?


Actually, this really depends on what you are trying to accomplish with your new preprocessor. Are you trying to create an application decoder to pass plain text data back the rules engine for analysis? Are you trying to create an anomaly detection tool out of nonstandard rules?


For a really long, hard look at how to create your own preprocessor, see Jay Beale's entire chapter on the subject in the Snort 2.1 book from Syngress Publishing.
