CWE-778 (不充分的日志记录) — Vulnerability Class 21

CWE-778 represents a critical logging weakness where security-critical events are either omitted or recorded with insufficient detail, severely impairing an organization’s ability to detect and respond to threats. Attackers typically exploit this gap by conducting stealthy malicious activities, such as brute-force login attempts or privilege escalation, without leaving a traceable audit trail. This lack of visibility hinders forensic analysis, allowing intruders to maintain persistence and evade detection for extended periods. To mitigate this risk, developers must implement comprehensive logging strategies that capture essential context for all security-relevant actions, including user authentication, authorization checks, and system configuration changes. By ensuring logs contain adequate timestamps, source IPs, and user identifiers, organizations can enhance their monitoring capabilities and facilitate rapid incident response when anomalies occur.
