Elastic Security Malicious Behavior Protection Rules

Prebuilt high signal EQL rules that runs on the endpoint to disrupt malicious behavior, this layer of prevention equips Elastic Agent to protect Linux, Windows, and macOS hosts from a broad range of attack techniques with a major focus on the following tactics :

• Initial Access
• Execution
• Privilege Escalation
• Defense Evasion
• Credential Access
• Impact

Prevention is achieved by pairing post-execution analytics with response actions to kill a specific process or a full process tree tailored to stop the adversary at the initial stages of the attack. Each protection rule is mapped to the most relevant MITRE ATT&CK tactic, technique and subtechnique.

The true positive rate that we aim to maintain is at least 70%, thus we prioritize analytics logic precision to reduce detection scope via prevention.

Another example of our commitment to openness in security is our existing public Detection Rules repository where we share EQL rules that run on the SIEM side, and that have a broader detection logic which make them more suitable for detection and hunting.
