- Identification of abnormal patterns
- Detection of known and unknown intrusion signatures
Solutions like Darktrace use machine learning to autonomously understand network behavior and flag threats such as lateral movement, data exfiltration, or brute-force login attempts.
Behavioral Analytics to Spot Insider Threats
Not all threats come from outside. In fact, insider threats — whether malicious or negligent — pose significant risks. Here, AI in cybersecurity shines by using User and Entity Behavior Analytics (UEBA).
AI-driven UEBA tools monitor:
- User access patterns
- File movements and downloads
- Login activity and system commands
When a deviation from typical behavior is detected, the system flags or blocks the suspicious activity. Platforms like Exabeam and Splunk leverage AI to detect and prevent insider threats before damage occurs.
Automating Security Operations with AI
Manual cybersecurity operations often struggle to keep up with today’s attack volumes. AI brings automation to Security Operations Centers (SOCs), enhancing both speed and accuracy.
