Whalescan

Whalescan is a vulnerability scanner for Windows containers, which performs several benchmark checks, as well as checking for CVEs/vulnerable packages on the container. It also checks the config and Docker files for misconfigurations. This tool can be used as part of a Windows container review on local copies of the containers, and on the host itself to enhance security.

Whalescan performs the following checks on containers:

• Container checks
  • Checks if containers are stored under C: drive – this could raise issues if there is a DoS attack, filling up the C: drive and making the host unresponsive
  • Checks if the container is running as a process or hyper-v. Hyper-v isolation offers enhanced security of containers
  • Checks if there are any pending updates in the containers, and if so, how to update.

  

• Image checks
  • Checks for unsafe commands being used in the dockerfile, for example, docker ADD instead of docker COPY.
  • Checks if hash verification is being performed on any files downloaded.
  • Checks if any vulnerable packages are on the container, and pulls relevant CVE information
  • Checks if .NET version being used is End Of Life
  • Checks if Docker Engine is updated, and if not, gathers a list of CVEs for the version being used

  

• Checks permissions of docker configuration files
• Checks if additional devices have been mapped to containers
