DNSSEC (Domain Name System Security Extensions) adds cryptographic signatures to DNS records to ensure authenticity and integrity. It prevents attacks such as DNS spoofing and cache poisoning.

DNSSEC allows clients to verify that DNS responses have not been altered. It is the industry-standard solution recommended by security frameworks for protecting DNS infrastructure.

An Advanced Persistent Threat (APT) involves stealthy, long-term access to systems for espionage, data theft, or sabotage.

Clear roles ensure fast, coordinated response, reduce confusion, and prevent duplicated or missed actions during incidents.

Simulations provide realistic testing by executing scenarios that closely mirror real disruptions, revealing gaps and readiness levels better than discussions or reviews.
