Security management guarantees the security of the DNS by means of user classification and privilege management.

Security management includes the user management, command group management, and password management functions:

• User
  management: The system supports addition, deletion, and modification of
  a user. The account, password, operation time limit, and operation
  rights can be set and modified. The operation time limit is the
  lifecycle of a user account. Operation
  rights are defined by assigning command groups for users.
• Command
  group management: The system divides commands into groups according to
  certain rules, G_0 to G_11 are default command groups in the system.
  Users can define a command group to meet requirements. For example,
  users can set the name of a command
  group and define a new command group.
• Password management: The
  system supports the setting of password policies, which can increase the
  complexity of the password and enhance the system security.
