What is a significant challenge in Computer Network Defense?

The constantly evolving nature of cyber threats is a significant challenge in Computer Network Defense because cyber adversaries consistently develop more sophisticated tactics, techniques, and procedures. As technologies advance, attackers become more adept at exploiting vulnerabilities, which requires defenders to remain vigilant and continuously adapt their strategies. This dynamic environment means that what may have been an effective defense yesterday might not be effective today, necessitating ongoing updates to security protocols, threat intelligence, and response strategies.

This evolution also complicates the task of training personnel, as they must stay current with the latest threats and defense mechanisms, and ensure that systems are secure against new and emerging vulnerabilities. Consequently, organizations must foster a culture of adaptability and resilience to keep pace with the constantly changing cyber landscape.
