Which of the following is NOT a typical aspect of domain security policy management?

In the context of domain security policy management, the activities typically involve the governance and access control mechanisms that protect data and resources within a system. Assigning user roles, defining security groups, and controlling feature opt-in are all critical aspects of ensuring that users have appropriate access rights and that sensitive information is properly protected.

Assigning user roles is essential as it determines what actions users are allowed to perform within the system based on their responsibilities and organizational roles. Similarly, defining security groups allows for the organization of users into various categories, making it easier to manage permissions efficiently on a broader scale.

Controlling feature opt-in is also a significant part of domain security. This involves managing which features are available to users based on their roles or security groups, ensuring that users have access only to the functionalities that they need for their work.

On the other hand, testing integration performance does not fall under the umbrella of domain security policy management. This process typically relates more to assessing how well different systems work together rather than managing user access or data security. Therefore, while performance testing is crucial for overall system health, it does not pertain to the specific goal of securing data or managing access policies.
