Container scanning is a comprehensive process that involves tools, techniques, tips, and tricks to detect and uncover all the hidden vulnerabilities within the containers and all their components. It is a key step, or the most important step to be precise, towards Container security. Both developers and the security teams get a fair idea of where things could go wrong. Moreover, it gives the cybersecurity teams room to fix the security loopholes and prepare a response plan as well, in case of any incident.
of organizations are planning to include containerized apps in their infrastructure over the next year.
has been the growth rate of containerization among businesses through the last year.
of respondents during a study in 2019 said that their container strategy wasn’t detailed enough.
of container users had to deal with at least one security incident over the last 12 months.
As we have already established that there are several ways through which vulnerabilities infiltrate your container environment. So, you need to scan every potential gateway and aspect of your containers. The software inside the container, the interaction mechanism between the container and host OS as well as between adjacent containers, and the network configurations also need to be checked.
There are automated container scanner tools for analyzing all aspects of the container environment and detecting security vulnerabilities. Whether it is a vulnerability introduced by code, or through images, these tools can scan and uncover them effectively. Even if you get your images from trusted sources, there are still slight chances that they might contain vulnerabilities. When you detect a bunch of vulnerabilities together, it allows you to fix them all at once.
You can easily integrate security scanners during various stages of development. A few tools come with IDE plugins that enable you to scan Docker files and indicate alternative images having fewer vulnerabilities or are slimmer in size. Integrating vulnerability scanning to continuous delivery (CI/CD) pipelines is also an approach that a lot of organizations adopt to make things smoother.
The following are a few different types of container security scanning technologies:
Even with the most full-proof vulnerability scanning service, you need to make sure that all your steps are in line with security. The following are the best practices you can adopt for scanning vulnerabilities efficiently within containers:
