Understanding Amazon Inspector¶
Amazon Inspector is a fully managed vulnerability management service that automates the process of identifying security vulnerabilities in your AWS infrastructure. This service covers various components, including:
- Amazon EC2 Instances: Scans to find potential security issues and misconfigurations.
- Container Images: Scans stored images in ECR for known vulnerabilities.
- AWS Lambda Functions: Evaluates functions for their security configurations.
By continually monitoring these components, Amazon Inspector aims to highlight potential risks before they can be exploited, enabling organizations to mitigate threats effectively.
Container Vulnerabilities: The Need for Scanning¶
Containerization has revolutionized application deployment, providing benefits like scalability and isolation. However, vulnerabilities within container images, especially in third-party libraries or dependencies, can lead to significant security risks.
Common types of vulnerabilities in container images include:
- Known Vulnerabilities: Issues with libraries and packages that are known and logged within vulnerability databases like CVE (Common Vulnerabilities and Exposures).
- Configuration Weaknesses: Poor configurations that can lead to unnecessary exposure of services.
- Exposure of Sensitive Data: Unintended inclusion of sensitive data within images.
With a majority of modern applications relying on third-party code, it is vital to keep scans current and comprehensive to avoid potential exploitation.
The Upgrade: What’s New in Amazon Inspector¶
The recent upgrade to Amazon Inspector’s security engine for container image scanning introduces several key features:
Enhanced Dependency Collection: The engine now excels in collecting more comprehensive dependency trees to identify vulnerabilities within all layers of a container image.
Automatic Re-evaluation: The service automatically reassesses existing resources as it identifies newly discovered vulnerabilities, which can close previously opened findings while highlighting others.
Broader Vulnerability Coverage: With refined data sources and improved heuristic scanning techniques, users can expect better detection rates for both known and newly surfaced vulnerabilities.
Less Disruption: These upgrades occur automatically with no required action from the user, ensuring ongoing security without workflow disruption.
How Amazon Inspector Scans Container Images¶
Amazon Inspector uses a systematic approach to scan container images housed in Amazon Elastic Container Registry. Here’s how the scanning process generally works:
Image Retrieval: The scan begins with retrieving images from the specified ECR repository.
Layer Analysis: Each layer of the container image is analyzed, focusing on both application code and the libraries included in the image.
Vulnerability Identification: The scanning engine utilizes a range of data feeds, including industry-standard vulnerability databases, to identify known vulnerabilities associated with the libraries in use.
Findings Generation: Throughout the scanning process, Amazon Inspector generates findings that indicate vulnerabilities, categorized by their severity and the impacted dependencies.
Recommendations Provided: Following the findings, the system may also provide remediation guidance to help users address vulnerabilities effectively.
Benefits of Enhanced Scanning¶
With the upgrade to Amazon Inspector’s security engine, organizations stand to gain several advantages:
Comprehensive Vulnerability Management: Enhanced dependency mapping and automatic re-evaluation mean that organizations can continuously assess the security of their container images.
