True or False: Each group has a default permission level, but an administrator can modify any user group's permissions.

The statement is accurate because, in SonicWall's management system, each user group indeed comes with a default permission level that dictates what activities or resources members of that group can access or control. This default setting provides a baseline for security and administrative efficiency.

Moreover, the flexibility afforded to administrators to modify these permissions is crucial for tailored access control. Administrators can assess the needs of their organization and adjust permissions accordingly, ensuring that users have the appropriate access needed to perform their roles while maintaining the overall security posture of the network. This ability to customize user group permissions helps mitigate risks and adhere to policies regarding the principle of least privilege. Thus, the primary understanding behind the statement is that it reflects the fundamental capabilities provided to administrators in managing permissions within user groups.
