Container Image Security (IMG)
Container Image Security is a critical aspect of modern application deployment, ensuring the containerized environments you rely on are free from vulnerabilities and security risks.
What is Container Image Security?
Container Image Security analyzes the container images used across your development and production environments to detect vulnerabilities, misconfigurations and security risks. Container images package everything needed to run an application — code, runtime, libraries and settings — making them a critical element of modern DevOps.
Rainforest's Container Image Security solution scans these images to ensure they are secure, compliant and ready for deployment.
Layer-by-layer image analysis
The process examines container images comprehensively — from the base image to every added dependency — to surface potential security threats.
- 1
Image Scanning
The solution scans the container image layer by layer, analyzing the base image and any additional software or dependencies against a comprehensive database such as the NVD.
- 2
Vulnerability Detection
It identifies vulnerabilities within the image, including outdated or insecure packages, libraries with known flaws and misconfigurations that could expose the container.
- 3
Compliance Checks
It verifies the image against security best practices and organizational policies, including industry standards such as CIS benchmarks.
- 4
Misconfiguration Analysis
Beyond vulnerabilities, it looks for misconfigurations that could compromise the container — improper settings, weak credentials and insecure network configurations.
- 5
Reporting & Remediation
A detailed report highlights the vulnerabilities, misconfigurations and compliance issues found, with actionable recommendations to address them quickly.
- 6
Continuous Security
Integrated into CI/CD pipelines, it continuously scans images as they are built and updated, so only secure images reach production.
Only ship secure, compliant images
Container Image Security is essential for organizations that use containerization to deploy applications, especially where high levels of security and compliance are required. A typical use case is during the build and deployment stages, where images are scanned before being pushed to production — preventing breaches caused by vulnerable or misconfigured containers. In finance, healthcare and government, it ensures every deployed container meets stringent standards, reducing the risk of non-compliance penalties.
Frequently asked questions
What does Container Image Security scan?
It analyzes container images layer by layer for known vulnerabilities, misconfigurations, insecure packages and compliance gaps — from the base image to every dependency.
Does it check for misconfigurations?
Yes. Beyond vulnerabilities, it flags misconfigurations such as improper settings, weak credentials and insecure network configurations.
Does it support compliance standards?
Yes. It verifies images against security best practices and standards such as CIS benchmarks, plus your own organizational policies.
When should images be scanned?
Ideally during the build and deployment stages, before images are pushed to production — and continuously as images are rebuilt.
Can it run in CI/CD?
Yes. It integrates into CI/CD pipelines to continuously scan images as they are built and updated.
Secure images from build to registry
Catch vulnerabilities and misconfigurations before your containers ever reach production.
