The project has a vibrant community that provides frequent updates. As stated on the project’s website: “Sigma is for log files what Snort is for network traffic and YARA is for files.” Moreover, the Sigma repository comes with about 500 built-in rules for several target log sources, including Windows, Linux, web, network, cloud and more. It enables the development of shareable detection methods across various SIEMs. Sigma is a generic and open signature format for log events. We begin by describing the use of an event log rule format that’s an open-source standard and is applicable to any type of log file. This blog describes how IBM is contributing to this community effort. With this challenging reality, pulling together the wisdom of the security community and sharing open-source tools, techniques and best practices is a powerful approach for protecting enterprises against cyber threats. Additionally, attackers are using sophisticated techniques to avoid existing detection mechanisms by altering their behaviors. New attacks arise daily and most of their damage is achieved in the first few hours before organizations know they have been breached. The detection rules/analytics of today must therefore dynamically adapt to the threat landscape over time. Threat detection is a growing challenge, and one that demands constant attention since attackers continuously gain expertise and sophistication and threats are ever-changing. Once a potential threat is detected, the staff of the security operations center (SOC) investigates it and, if it is found to be a real risk, responds, contains and mitigates it. Common means to achieve this goal are rules or analytics that track network and system behaviors and raise alerts when potentially malicious attacks are identified. Detecting cyber threats is usually the first critical step in the mitigation of cyber attacks.
