AI and the New Age of Cyber Defense
Artificial intelligence is quickly changing how we protect digital systems. For years cybersecurity meant reacting to threats after they happened. Now AI is making it possible to predict, detect, and stop attacks before they spread. Modern AI models are trained on enormous datasets of network logs, malware signatures, and behavioral patterns. They can learn what normal activity looks like and instantly spot deviations that signal an attack. Some systems even simulate hacker behavior to test defenses and patch vulnerabilities before real attackers find them. https://www.ibm.com/security/artificial-intelligence A recent study in Nature Machine Intelligence showed how generative AI can automatically craft realistic phishing campaigns to train employees and strengthen awareness programs. Instead of static exercises, organizations can now use adaptive simulations that evolve just like real-world threats. https://www.nature.com/articles/s42256-025-00824-2 The biggest change, th...
