DNS is a crucial yet underutilized asset for Chief Information Security Officers (CISOs) in combating cyberattacks. As the first point of detection, DNS can prevent attacks by blocking malicious queries, disrupting command-and-control communications, and stopping data exfiltration. Recent advancements in AI have enabled cybercriminals to adapt rapidly, creating polymorphic malware and sophisticated phishing campaigns. By leveraging protective DNS combined with threat intelligence, CISOs can proactively safeguard their networks from evolving threats, urging a strategic shift to utilize DNS as a frontline defense system in the cybersecurity landscape.
