Cybersecurity and Counterintelligence are two vital areas of modern defense that protect sensitive information and national security from cyber threats and espionage. Cybersecurity focuses on safeguarding digital systems, networks, and data from attacks, while counterintelligence aims to detect and neutralize foreign espionage activities. In an increasingly connected world, the intersection of these two disciplines is crucial in defending against cyber attacks, preventing unauthorized access, and identifying attempts to steal national secrets or sabotage operations. With rising global threats, organizations and governments are prioritizing robust cybersecurity measures and counterintelligence strategies to safeguard their integrity and security.
