Installation of software on operational systems

Software under development, testing and production is run in differentiated technical environments in order to ensure the quality of development work in an environment that adapts to the production environment and, on the other hand, the production environment is not disturbed by unfinished development.

Sensitive or personal data of users is not copied and used in a development environment.

Only pre-defined, authorized users are allowed to post changes to the code.

Unmanaged installations of software on computers can lead to vulnerabilities and security breaches.

The organization should determine what types of software or updates each user can install. The instructions may include e.g. the following guidelines:

• only specially designated persons may install new software on the devices
• programs previously designated as secure may be installed by anyone
• use of certain software may be impossible for everyone
• existing software updates and security patches are allowed to be installed by anyone

An event log should be kept for all updates to production or customer software or in-house IT services.
