Your company has a main office and a branch office. Each office has an IT staff. Each office contains an ISA Server Enterprise Edition array that provides firewall and proxy services. You create two security groups named MainIT and BranchIT. You add the user accounts for the IT staff from the main office to the MainIT group. You add the user accounts for the IT staff from the branch office to the BranchIT group.
You need to configure the security of your ISA Server environment to meet the following requirements:
Give the IT staff in the main office full administrative access to both ISA Server arrays. Allow IT staff in the branch office to view firewall rules for the branch office ISA Server array. Prevent IT staff in the branch office from changing the configuration of the branch office ISA Server array.
Prevent IT staff in the branch office from accessing the configuration of the main office ISA Server array.
