Why You Need Software Composition Analysis (SCA) Along With Container Security Scanner

Learn why software composition analysis (SCA) is essential for identifying and managing vulnerabilities in your containerized applications, and how it complements container security scanner.

Container security scanner is a tool that scans the base OS and the libraries and application binaries that are included in the container image. It helps to detect and prevent vulnerabilities in the container environment. However, container security scanner alone is not enough to ensure the security of your containerized applications. You also need software composition analysis (SCA) to identify and manage the vulnerabilities in the open source components and dependencies that your application uses.

What is Software Composition Analysis (SCA)?

SCA is a process that analyzes the software components and dependencies that are used in an application. It helps to identify the open source licenses, security risks, and quality issues associated with the components and dependencies. SCA also provides remediation guidance and automated fixes for the identified vulnerabilities.

SCA is especially important for containerized applications, as they often rely on multiple layers of open source components and dependencies. According to a report by Snyk, 70% of the vulnerabilities in container images are found in the application layer, not the base OS layer. Therefore, scanning the container image alone is not sufficient to detect all the vulnerabilities in the application layer.

How Does SCA Complement Container Security Scanner?

Container security scanner and SCA are complementary tools that provide different perspectives and capabilities for securing your containerized applications. Here are some of the benefits of using both tools together:

  • Container security scanner helps to detect and prevent vulnerabilities in the container environment, such as the base OS, the container runtime, the orchestration platform, and the network. It also scans the container image for vulnerabilities in the libraries and application binaries that are included in the image.
  • SCA helps to detect and manage vulnerabilities in the open source components and dependencies that are used by the application. It also provides information about the open source licenses, security risks, and quality issues associated with the components and dependencies. SCA also helps to track and update the components and dependencies throughout the software development lifecycle (SDLC).
  • By using both tools together, you can get a comprehensive view of the vulnerabilities in your containerized applications, and prioritize and remediate them accordingly. You can also ensure compliance with the open source licenses and policies, and improve the quality and performance of your applications.

Frequently Asked Questions (FAQs)

Question: What are some of the common vulnerabilities in containerized applications?

Answer: Some of the common vulnerabilities in containerized applications are:

  • Misconfigured or outdated container runtime, orchestration platform, or network
  • Insecure or untrusted container images or registries
  • Vulnerabilities in the base OS, libraries, or application binaries that are included in the container image
  • Vulnerabilities in the open source components or dependencies that are used by the application
  • Excessive or unnecessary privileges or permissions for the containers or the applications

Question: How can I scan my container images for vulnerabilities?

Answer: You can use a container security scanner tool to scan your container images for vulnerabilities. Some of the popular container security scanner tools are:

  • Aqua Security
  • Snyk
  • Anchore
  • Clair
  • Trivy

Question: How can I scan my open source components and dependencies for vulnerabilities?

Answer: You can use a software composition analysis (SCA) tool to scan your open source components and dependencies for vulnerabilities. Some of the popular SCA tools are:

  • Snyk
  • WhiteSource
  • Black Duck
  • JFrog Xray
  • Sonatype Nexus

Summary

Container security scanner and SCA are complementary tools that provide different perspectives and capabilities for securing your containerized applications. Container security scanner helps to detect and prevent vulnerabilities in the container environment, while SCA helps to identify and manage vulnerabilities in the open source components and dependencies. By using both tools together, you can get a comprehensive view of the vulnerabilities in your containerized applications, and prioritize and remediate them accordingly.
