Security

To ensure protection of your data, Double-Take Availability offers multi-level security using native operating system security features. Privileges are granted through membership in user groups. The groups can be local or LDAP (Lightweight Directory Access Protocol). To gain access to a particular Double-Take Availability source or target, the user must provide a valid local user account that is a member of one of the Double-Take Availability security groups. Once a valid user name and password have been provided and the Double-Take Availability source or target has verified membership in one of the Double-Take Availability security groups, the user is granted appropriate access to the source or target and the corresponding features are enabled in the client. Access to Double-Take Availability is granted on one of the following three levels.

Administrator Access—All Double-Take Availability features are available for that machine. This security group name is dtamin, and the default group ID is 501.
Monitor Access—Servers and statistics can be viewed, but functionality is not available. This security group name is dtmon, and the default group ID is 502.
No Access—Servers appear in the clients, but no access to view the server details is available.

Although Double-Take Availability passwords are encrypted when they are stored, Double-Take Availabilitysecurity design does assume that any machine running the Double-Take Availability client application is protected from unauthorized access. If you are running the Double-Take Availability client and step away from your machine, you must protect your machine from unauthorized access.
