Which log type would be crucial for investigating potential malware breaches?

Threat logs are crucial for investigating potential malware breaches because they specifically track malicious activities, security incidents, and indicators of compromise. These logs provide detailed records of attempts to exploit vulnerabilities, the types of threats detected, and any malware signatures that have been identified. By analyzing threat logs, security professionals can pinpoint unauthorized access attempts, understand the attack vectors used by malware, and formulate an appropriate response to mitigate the risk further.

In contrast, access logs primarily record user activities and access attempts to systems, which can help in terms of monitoring user behavior but do not directly indicate malware behavior. System logs document system events, including performance metrics and operations, while configuration logs focus on changes in system configurations. Although these logs can indirectly aid in security investigations, they do not provide the targeted insights into threats that threat logs offer.
