How does the Cacti system handle user permission management and access control?

The Cacti system offers basic user permission management and access control functions, which can be configured by following these steps:

1. Creating users: In the Cacti system, administrators can establish new user accounts and assign different permissions and roles to each user.
2. Assigning roles: Administrators can assign different roles to each user, such as administrator, operator, or regular user, with each role having different permissions.
3. Permission settings: Administrators can define access levels for different users or roles, such as accessing devices, viewing charts, editing charts, etc.
4. Access control: administrators can establish access control rules to restrict users to only access specific devices or data sources, ensuring the security of the system data.
5. Logging: The Cacti system also offers logging functionality, allowing administrators to view user operations records and monitor user behavior.

Setting up user permission management and access control through the above steps can protect the security of system data and prevent unauthorized users from accessing and operating the system.
