Security
To ensure protection of your data, Storage Mirroring offers
multi-level security using native operating system security features.
Privileges are granted through membership in user groups defined
on each machine running Storage Mirroring. To gain access to a particular Storage Mirroring source
or target, the user must provide a valid operating system user name and password and the specified
user name must be a member of one of the Storage Mirroring security groups. Once a valid user name
and password have been provided and the Storage Mirroring source or target has verified
membership in one of the Storage Mirroring security groups, the user is granted appropriate access
to the source or target and the corresponding features are enabled in the client. Access to Storage
Mirroring is granted on one of the following three levels:

Administrator Access—All Storage Mirroring features are available for that machine. For
example, this access level includes creating replication sets and establishing Storage Mirroring
connections.

Monitor Access—Statistics can be viewed on that machine, but Storage Mirroring features are
not available. For example, this access level does not allow the user to create or modify
replication sets or create or modify Storage Mirroring connections.

No Access—The machine appears in the Storage Mirroring Management Console and can be
pinged using a scripting command, but no other access is available.
Security access levels
The following table identifies which key Storage Mirroring features are available depending on the
security access granted.
Security advantages and considerations
Storage Mirroring security provides machine-based protection allowing the network administrator to
specify the individuals that can access all of the Storage Mirroring features as well as those that only
have access to the Storage Mirroring statistics. This security prevents unauthorized users from
modifying critical Storage Mirroring configurations like the data included or excluded from a
replication set, changing a one-to-one configuration to a one-to-many configuration by adding
another connection, or initiating a mirror or stopping replication.

NOTE: Although Storage Mirroring passwords are encrypted when they are stored, Storage
Mirroring security design does assume that any machine running the Storage Mirroring
client application is protected from unauthorized access. If you are running the Storage
Mirroring client and step away from your machine, you must protect your machine from
unauthorized access.
