# Configuring Snort IDS for Intrusion Detection

## When to Use

- Deploying a network-based intrusion detection system to monitor traffic at key network boundaries
- Writing custom Snort rules to detect organization-specific threats, attack patterns, or policy violations
- Tuning existing rulesets to reduce false positives while maintaining detection coverage
- Integrating Snort alerts with SIEM platforms for centralized security monitoring
- Validating network security controls by generating test traffic and confirming detection

**Do not use** as a replacement for endpoint detection, for monitoring encrypted traffic without TLS inspection, or as the sole security control without complementary defenses.

## Common Misconfigurations & Verification

- **HOME_NET wrong or too narrow:** if `HOME_NET` doesn't cover your real subnets (or is left at a sample like `10.10.0.0/16` when you're `192.168.x`), every `$HOME_NET`/`$EXTERNAL_NET` rule misfires and east-west traffic is unscored. Verify with `snort -c snort.lua -T` and grep the resolved value; test a rule that should fire on internal traffic.
