+# **Naxsi Rules**
+
+A Naxsi rule is a search pattern which is applied to a request to detect malicious behaviour.
+
+A rule is defined by `MainRule` or `BasicRule` directive, an **id**, a **search parameter** (i.e. case-insensitive string or regex), a **matchzone**, a **score** and an **optional description**.
+
+Example of rule:
+
+```bash
+MainRule id:12345 "s:$FOO:8,$BAR:4" "str:malicious" "mz:URL" "msg:string rule description";
+BasicRule id:67890 "s:$TOO:4" "rx:[a-z]{5}" "mz:ARGS" "msg:regex rule description";
+```
+
+## **Internal Rules**
+
+Naxsi has some internal rules that are hardcoded within the WAF; these rules are defined by **ids** lower than **1000**.
+
+> ⚠️ Warning
+>
+> No rules shall be defined with **ids** lower than 1000.
+
+You can read more about them here: [Internal Rules](internal_rules.md).
+
+## **`MainRule` and `BasicRule` directives**
+
+As explained in the directives chapter we can have 2 kinds of rules:
+
+- [A **global** rule defined by the `MainRule` directive](directives.md#mainrule)
+- [A **location-specific** rule defined by the `BasicRule` directive](directives.md#basicrule)
+
+These two directives are mandatory to define rule.
