# Audit DNS Security

DNS misconfigurations are a common attack vector. Missing SPF records let anyone spoof your email. Dangling CNAME records pointing to decommissioned services can be hijacked. Wildcard records can expose internal subdomains. These issues are easy to miss and expensive to exploit.

Using lookup_dns and check_ssl together, you can audit your domain for common security issues. Check for missing or misconfigured records, verify that SSL certificates are valid and properly chained, and identify entries that could be exploited by attackers.

**Tool:** [DNS Domain](https://toolrouter.com/tools/dns-domain)
**Skills:** lookup_dns, check_ssl
