Trivy
Why this is correct
Trivy is an open-source vulnerability scanner specifically designed for containers, Kubernetes, and IaC templates. It excels at detecting vulnerabilities in OS packages and application dependencies within container images, making it ideal for integration into CI/CD pipelines.
- ✗
OpenVAS
Why it's wrong here
OpenVAS is a comprehensive network vulnerability scanner that identifies security issues in active hosts, operating systems, and network services. It relies on network-based probes and authenticated scans rather than analyzing static container image layers or filesystem manifests.
- ✗
Nessus
Why it's wrong here
Nessus is a widely used, general-purpose vulnerability assessment tool designed to scan enterprise infrastructure, endpoints, and cloud configurations. While it can assess host operating systems running container runtimes, it is not the primary tool for parsing and scanning static container image registries.
- ✗
Burp Suite
Why it's wrong here
Burp Suite is an integrated platform designed for performing security testing of web applications, focusing on HTTP/S traffic interception, manipulation, and dynamic analysis. It does not possess the capability to unpack container image layers, inspect base OS packages, or analyze containerized application dependencies.
