Software packages included with the installation of JS7 components products can be enabled and disabled by use of the Package Management Script.

...

• Rollout of JS7 products is considered critical as the software allows jobs to be executed on a larger number of servers.
  • Vulnerabilities in 3rd-party libraries components of JS7 products deserve attention.

• The solution provided for software package management is based on shell scripting by design:
  • to provide readability and to rely on OS commands only,
  • to deny the use of 3rd-party components and additional dependencies that require code to be executed.
• The Software Package Management Script can be integrated in a number of ways:
  • by running the script directly on the related server.
  • by running one's own SSH scripts ,for use with remote servers.
  • by use with tools such as Ansible®, Puppet® that make use of an SSH Client,
  • by use of JS7 workflow automation.
