Since layers can be shared between many containers, introspection is vital to build an inventory of packages and match that against known CVEs.Ĭlair has also introduced support for programming language package managers, starting with Python, and a new image-oriented API.Īutomatic detection of vulnerabilities will help increase awareness and best security practices across development and operations teams, and encourage action to patch and address the vulnerabilities. Clair scans each container layer and provides a notification of vulnerabilities that may be a threat, based on the Common Vulnerabilities and Exposures database (CVE) and similar databases from Red Hat ®, Ubuntu, and Debian.
