Docker Rolls Out Tool to Scan Containers for Vulnerabilities
Among the big pieces of news that Docker Inc. announced at its DockerCon EU conference in November 2015 was its Project Nautilus effort to scan Docker repositories for security vulnerabilities. Now six months later, the company is making Nautilus generally available under the product name Docker Security Scanning. And Docker is complementing the new security product with an update to Docker Bench, a container best practices security tool, further improving the overall security tooling for Docker.
"What was announced at DockerCon was the use of Nautilus for Docker Official Repos [repositories] only and did not have a workflow that ties to the end-to-end software supply chain," Nathan McCauley, director of security at Docker, told eWEEK.
Docker Security Scanning is available to Docker Cloud private repository customers for a limited time free trial, eventually expanding to include all Docker Cloud repository users, according to McCauley. Pricing starts at $2 per repository as an add-on service for private repository plans. Docker Security Scanning will also be available as an integrated feature in Docker Datacenter, which is Docker Inc.'s premier commercial product that officially debuted in February.
Docker Security Scanning's goal is to help developers and enterprises find and identify known vulnerabilities in Docker container images. It is being applied to all the official images on the Docker Hub repository for container images, McCauley said. The general availability adds the ability for Docker Cloud subscribers to scan their private repositories.
The Project Nautilus effort first announced in 2015 and now named Docker Security Scanning is now generally available as container security ramps up.
"Previously, IT operations would have to rely on the information published by each ISV on the state of their content and have to actively monitor the CVEs [Common Vulnerability and Exposures] for each one," he said. "Docker Security Scanning looks for known CVEs by generating a bill of materials for Docker images using a static analysis scan of the image itself."
