What logs and metrics are most useful for Image scanning?

When implementing image scanning in a DevOps pipeline, monitoring and logging play a crucial role in ensuring that vulnerabilities are detected and addressed promptly. Here are some of the most useful logs and metrics for image scanning:

  • Vulnerability Scanning Results: Logs that detail found vulnerabilities, their severity level, and the affected packages.
  • Scan Duration: Metrics indicating how long the scanning process takes, which can help optimize pipeline performance.
  • Scan Frequency: Track how often scans are performed to ensure consistent monitoring of images.
  • False Positives Rate: Metrics identifying the rate at which vulnerabilities are incorrectly reported.
  • Deployment Success Rates: Logs showing the success or failure rate of deployments following image scans.

By collecting and analyzing these logs and metrics, DevOps teams can enhance their security posture, improve scanning processes, and maintain the integrity of their applications.

<?php // Example of logging vulnerability scan results $scanResults = [ 'vulnerabilities' => [ ['id' => 'CVE-2023-12345', 'severity' => 'high', 'package' => 'example-package'], ['id' => 'CVE-2023-67890', 'severity' => 'medium', 'package' => 'another-package'], ], 'scan_duration' => '30 seconds', 'scan_timestamp' => date('Y-m-d H:i:s'), ]; // Logging to a file file_put_contents('scan_log.json', json_encode($scanResults)); ?>
