Incident Response – Detecting and Analyzing Threats Through Malicious Behavior
One of the challenges in responding to cyber threats is monitoring and responding to attacks that continuously evolve in their methods and techniques. Relying solely on signature-based detection, which identifies specific characteristics of attack patterns, may not be sufficient. It’s necessary to also incorporate anomaly detection or abnormal behavior analysis for more comprehensive coverage. Although there are tools available today to assist in detecting such incidents, the ability of analysts to understand how these tools work or to identify abnormalities that the tools might miss can greatly enhance the accuracy of threat response. The incident response process, as recommended by NIST SP 800-61r2, is divided into four steps. This article focuses on step 2, Detection and Analysis. The aim is to help those involved in threat analysis understand how to detect and analyze malicious behavior.
