DNS Security Assessment: Protecting Your Most Critical Infrastructure for Malaysian Enterprises

DNS is the foundation of internet connectivity — compromise DNS and you redirect all traffic. DNS security assessment covers: DNS infrastructure configuration (redundancy, access controls, update mechanisms), DNSSEC implementation (is response authenticity verified?), DNS hijacking prevention (registrar security, domain lock), DNS tunneling detection (can attackers exfiltrate data through DNS queries?), DNS cache poisoning resilience, and monitoring for DNS-based command and control communication. Many organisations invest heavily in application security while leaving DNS infrastructure with default configurations.
