Container image security

By proactively securing container images, security teams can prevent vulnerabilities from reaching production, mitigate risks, and support a strong security posture.

This section outlines key practices for container image security, essential to building a resilient cloud infrastructure. 

• Image Trust: Image trust policies scan for vulnerabilities, misconfigurations, and embedded secrets, reducing the risk of compromised components. Establishing image trust is a fundamental step in securing your container pipeline. By implementing policies that enforce image signing, security scans, and misconfiguration checks, organizations ensure only verified images are deployed.

• SBOM (Software Bill of Materials): An SBOM is a detailed inventory of all components within a container image, promoting transparency and traceability across the supply chain. With an SBOM, teams can identify dependencies and track any vulnerabilities within container images, making it easier to respond to emerging threats and ensure compliance with security standards. 

• Best Practices: Always build images from trusted sources, regularly update components, and scan images before deployment. Automate these processes to maintain a consistent, reliable approach to image security. 

By prioritizing container image security, cloud security practitioners can protect critical assets, reduce the attack surface, and confidently support their organization’s security goals across the cloud environment.
