A centralized Software Bill of Materials (SBoM) is the best solution for identifying vulnerabilities in container images in a private repository. An SBoM provides a comprehensive inventory of all components, dependencies, and their versions within a container image, facilitating quick evaluation and response to vulnerabilities.
Why Centralized SBoM?
Comprehensive Inventory: An SBoM lists all software components, including their versions and dependencies, allowing for thorough vulnerability assessments.
Quick Identification: Centralizing SBoM data enables rapid identification of affected containers when a vulnerability is disclosed.
Automation: SBoMs can be integrated into automated tools for continuous monitoring and alerting of vulnerabilities.
Regulatory Compliance: Helps in meeting compliance requirements by providing a clear and auditable record of all software components used.
Other options, while useful, do not provide the same level of comprehensive and efficient vulnerability management:
A: SAST scan reports: Focuses on static analysis of code but may not cover all components in container images.
C: CIS benchmark compliance reports: Ensures compliance with security benchmarks but does not provide detailed component inventory.
D: Credentialed vulnerability scan: Useful for in-depth scans but may not be as efficient for quick vulnerability evaluation.
