Indicators of compromise (IOCs) are useful for?

Indicators of Compromise (IOCs) are key components in the cybersecurity field that help in identifying potentially harmful activities or breaches within a system. These indicators can include patterns such as unusual network traffic, specific file hashes that are known to be malicious, or IP addresses associated with known threats.

When a security team monitors for these IOCs, they can quickly recognize when something unusual occurs that deviates from the norm, which may indicate a security breach or an ongoing attack. As a result, IOCs are instrumental in the early detection of intrusions, enabling timely response and mitigation efforts. This proactive approach helps organizations protect their data, systems, and networks from potential threats.

The other choices, while important in their own domains, do not accurately relate to IOCs. Detecting software bugs involves debugging processes rather than identifying security threats. Improving system performance pertains to optimizing the functionality and speed of applications, which is unrelated to breach identification. Measuring user satisfaction focuses on gauging user experiences and feedback, another area distinct from cybersecurity concerns.
