# Suricata Rules Basics

This skill covers the core building blocks of Suricata signatures and how to express multi-condition DPI logic.

## Rule anatomy
A typical alert rule looks like:

```
alert <proto> <src> <sport> -> <dst> <dport> (
  msg:"...";
  flow:...;
  content:"..."; <buffer/modifier>;
  pcre:"/.../"; <buffer/modifier>;
  sid:1000001;
