Let’s find out!

Hackers have gone very active in the past few years. Even big organizations like Facebook, Google, and Yahoo have been victims to attacks losing millions of dollars. That is why an application’s security is the utmost important thing in every organization today.

Many of these applications today run inside containers as they are easily scalable, cost-effective, faster deployable, takes lesser storage, and uses resources far better than virtual machines. So, the security factor of these containers is very crucial. A container image is made up of layers, and to get a real understanding of an image’s vulnerability stance, you need to access each layer. The smaller container images have a lesser chance to get exposed to potential vulnerabilities.

Containerization is one of the core stages in the DevOps process where security must be looked on a serious note. A container image can have many bugs and security vulnerabilities, which gives a good opportunity for hackers to get access to the application or data present on the container costing millions to the company.

Hence, it is crucial to scan and audit the images and containers regularly. DevSecOps plays an important role in adding security to the DevOps processes, including scanning images and containers for bugs and vulnerabilities.

A container security scanner will help you find all the vulnerabilities inside your containers and monitor them regularly against any attack, issue, or a new bug.

Let’s explore the available options.

Clair

Clair is an open-source project which offers static security and vulnerability scanning for docker and application (appc) containers.

It is an API driven analysis engine which checks for security flaws in the containers layer by layer. You can build services using Clair, which can monitor your containers continuously for any container vulnerabilities. It notifies you about a potential threat in the container. It notifies you about a potential threat in the container based on the Common Vulnerabilities and Exposures database (CVE) and similar databases.

If any threat or issue identifies which is already there in the National Vulnerability Database (NVD), it will retrieve the details and provide the details in the report.
