Setting up internal accounts
Note: This feature is available only in advanced‑security devices.
Administrators can configure one internal account building block per supported device. Each internal account building
block can include a maximum of 750 user accounts and 32 user groups.
You can use this building block by itself in a security template to provide authentication‑level security, or with other
groups to provide both authentication and authorization.
Defining user groups
Before you begin, do the following:
• Create a list of all the users in the group.
• Identify the device functions needed for all users and for specific users.
Note: When a security template is assigned to a group, a role is created. Users can be assigned to more than one
group or role.
