Threat Detection in AWS with Prowler

Prowler enables threat detection in AWS by analyzing CloudTrail log records. To execute threat detection checks, use the following command:

prowler aws --category threat-detection

This command runs checks to detect:

• cloudtrail_threat_detection_privilege_escalation: Privilege escalation attacks
• cloudtrail_threat_detection_enumeration: Enumeration attacks
• cloudtrail_threat_detection_llm_jacking: LLM Jacking attacks

???+ note Threat detection checks are executed only when the --category threat-detection flag is used, due to performance considerations.

Config File for Threat Detection

To manage the behavior of threat detection checks, edit the configuration file located in config.yaml file from /prowler/config. The following attributes can be modified, all related to threat detection:

• threat_detection_privilege_escalation_threshold: Defines the percentage of actions required to classify an event as a privilege escalation attack. Default: 0.2 (20%)
• threat_detection_privilege_escalation_minutes: Specifies the time window (in minutes) to search for privilege escalation attack patterns. Default: 1440 minutes (24 hours).
• threat_detection_privilege_escalation_actions: Lists the default actions associated with privilege escalation attacks.
• threat_detection_enumeration_threshold: Defines the percentage of actions required to classify an event as an enumeration attack. Default: 0.3 (30%)
• threat_detection_enumeration_minutes: Specifies the time window (in minutes) to search for enumeration attack patterns. Default: 1440 minutes (24 hours).
• threat_detection_enumeration_actions: Lists the default actions associated with enumeration attacks.
• threat_detection_llm_jacking_threshold: Defines the percentage of actions required to classify an event as LLM jacking attack. Default: 0.4 (40%)
• threat_detection_llm_jacking_minutes: Specifies the time window (in minutes) to search for LLM jacking attack patterns. Default: 1440 minutes (24 hours).
• threat_detection_llm_jacking_actions: Lists the default actions associated with LLM jacking attacks.

Modify these attributes in the configuration file to fine-tune threat detection checks based on your security requirements.
