Securing the Supply Chain with Nutanix and Docker #dockercon2016

I was watching the below video from DockerCon 2016 and there was lots of striking similarities between what Nutanix and Docker is doing secure working environment for the Enterprise Cloud. There is no sense turning the alarm on for your house and then not locking the doors. You need to close all the gaps for your infrastructure and the applications that live on top of it.

The most interesting part of the session for me was the section on security scanning and gating. Docker has Security Scanning which is available as an add-on to Docker hosted private repositories on both Docker Cloud and Docker Hub. Scans run each time a build pushes a new image to your private repository. They also run when you add a new image or tag. Most scans complete within an hour, however large repositories may take up to 24 hours to scan. The scan traverses each layer of the image, identifies the software components in each layer, and indexes the SHA of each component.

The scan compares the SHA of each component against the Common Vulnerabilities and Exposures (CVE) database. The CVE is a “dictionary” of known information security vulnerabilities. When the CVE database is updated, the service reviews the indexed components for any that match the new vulnerability. If the new vulnerability is detected in an image, the service sends an email alert to the maintainers of the image.

A single component can contain multiple vulnerabilities or exposures and Docker Security Scanning reports on each one. You can click an individual vulnerability report from the scan results and navigate to the specific CVE report data to learn more about it.

On the Nutanix side of the fence all code is scanned with 2 different vulnerability scanners at every step of the development life-cycle. To top that off Nutanix already apply s an intrinsic baseline, and we already monitor and self-heal that baseline with SCMA the Security Configuration Management Automation and leverage the SaltStack framework so that your production systems can Self-Heal from any deviation and are always in compliance. Features like two factor authentication (2FA) and cluster lockdown further enhance the security posture. The cluster-wide setting can forward all logs to a central host as well. All CVEs related to the product are tracked and provide an internal turn around time of 72 hours for critical patches! There is some added time on getting a release cut but it fast and everything is tested as whole instead of a one off change that could have a domino a effect.

When evaluating infrastructure and development environments for a security-conscious environment, it’s imperative to choose one that is built with a security-first approach that continually iterate on patching new threats thereby reducing the attack surface. Docker is doing some great work on this front.
