Ensure images are scanned and rebuilt to include security patches

MoyenneNiveau 1Revue manuelledocker

Description

Images should be scanned frequently for any vulnerabilities. You should rebuild all images to include these patches and then instantiate new containers from them. Vulnerabilities are loopholes or bugs that can be exploited by hackers or malicious users, and security patches are updates to resolve these vulnerabilities. Reported as a manual review item: the audit needs a site-specific judgement.

Méthode de vérification

Méthode d'audit: Revue manuelle

Cette recommandation ne peut pas être vérifiée automatiquement. Une analyse la liste avec ces instructions lorsque vous passez --include-manual.

List all the running instances of containers by executing the command below: docker ps --quiet For each container instance, use the package manager within the container (assuming there is one available) to check for the availability of security patches. Alternatively, run image vulnerability assessment tools to scan all the images in your environment.

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Images should be re-built ensuring that the latest version of the base images are used, to keep the operating system patch level at an appropriate level. Once the images have been re-built, containers should be re-started making use of the updated images.
