Cybersecurity (Defensive AI)

AI has become an essential component of modern cybersecurity, and for good reason: the volume and sophistication of attacks have grown beyond what human analysts can monitor manually. AI-powered security tools analyse network traffic patterns to detect anomalies, identify malware using behavioural analysis rather than signature matching, correlate alerts across systems to identify coordinated attacks, and automate incident response for known threat types. These tools can process the millions of security events that a large organisation generates daily, filtering out noise and surfacing the genuine threats that need human attention. AI also helps with vulnerability management - scanning code and systems for potential weaknesses before attackers find them. The effectiveness of defensive AI depends heavily on the quality of its training data and the expertise of the team using it. False positives remain a significant problem - too many false alarms lead to alert fatigue, where genuine threats get buried in noise. AI security tools are powerful force multipliers for skilled security teams, but they are not a substitute for security expertise, sound architecture, and basic hygiene like patching and access control.
