Windows Server DNS DNSSEC Response Rate Limiting (RRL) Cache Locking Active Directory
Enterprise Active Directory DNS Security & Response Rate Limiting
Secured core domain name resolution infrastructure against cache poisoning, DNS amplification attacks, and unauthorized zone transfers.
Key Features & Implementation
- DNS Cache Locking: Enforced DNS cache locking at 100% to prevent overwriting cached records during active TTL periods.
- Restricted Zone Transfers: Configured DNS zone transfer permissions strictly to explicit, authorized secondary DNS server IP addresses.
- RRL & socket Pooling: Enabled Response Rate Limiting (RRL) and DNS socket pooling to neutralize DNS amplification attack vectors.
