Top 6 Advanced threat hunting techniques for OT and ICS networks
Advanced threat hunting involves proactively seeking out and identifying potential security threats within a network.The following are some of the techniques that can be used for advanced threat hunting in OT and ICS networks
Analyze network traffic to identify unusual or suspicious activity, such as excessive data transfers or communication with known malicious IP addresses
Network traffic analysis
Analyze endpoint devices for signs of malware or other malicious activity, such as altered system files, unauthorized software installations, or unexpected changes in configuration.
Analyze system logs and alerts to identify unusual or suspicious activity, such as failed login attempts, unexpected process launches, or unauthorized network connections
Analyze system memory to identify active malware and other malicious activity.
Utilize threat intelligence feeds to identify known threats and to develop a profile of the attacker's tactics, techniques, and procedures (TTPs).
Correlate data from multiple sources, including network activity logs, endpoint activity, and threat intelligence feeds, to identify patterns of behavior and identify potential threats.
Correlation of data
