security-logging

Security logging captures structured records of security-relevant events—authentication attempts, input validation failures, credential access—enabling detection and forensic tracing. Implement standardized log patterns at service startup to ensure consistent event capture across your infrastructure.

Input validation detects and sanitizes unsafe patterns at system boundaries: SQL injection attempts, cross-site scripting payloads, and malformed requests. Apply validation rules to API requests, filename inputs, and credential fields to block known attack vectors before processing.

Structured logging formats events with consistent fields—timestamps, user identity, action, result—making logs machine-parseable for automated monitoring and incident investigation. Log authentication, authorization decisions, and validation failures to trace security incidents end-to-end.

Credential security involves detecting secrets in logs, rotating credentials, and auditing access without exposing sensitive values. Implement secret-detection and remediation practices to prevent credential leakage while maintaining audit trails for compliance.

Yes. API request validation checks payload structure, enforces size limits, and detects malicious patterns; rate-limiting scaffolding prevents abuse. Combine validation with security logging to track rejected requests and limit-exceeded events for incident readiness.

Yes. Filename sanitization removes path traversal sequences and unsafe characters; request-size checks prevent resource exhaustion. These edge-case protections, combined with structured logging, ensure comprehensive security coverage at all system boundaries.
