Securing DNS Configurations
Without proper DNS hygiene, organizations are susceptible to traffic hijacking, subdomain takeovers, and email spoofing. Routine auditing of DNS zones is critical for maintaining corporate security postures.
Defensive Configurations
- Prevent Subdomain Takeovers: Ensure all CNAME records point to active resources. Dangling CNAMEs can be hijacked by unauthorized actors to host malicious content.
- Harden Email Infrastructure: Enforce strict SPF, DKIM, and DMARC policies in TXT records to cryptographically verify email senders and eliminate phishing.
- Protect Zone Transfers: Ensure authoritative nameservers do not permit anonymous AXFR zone transfers.
