You can have multiple
preauthentication policies that are bound to different levels. For example, you
have a policy that checks for a specific antivirus application bound to AAA
Global and a firewall policy bound to the virtual server. When users log on,
the policy that is bound to the virtual server is applied first. The policy
that is bound at AAA Global is applied second.
You can change the
order in which the preauthentication scans occur. To make NetScaler Gateway
apply the global policy first, change the priority number of the policy bound
to the virtual server, giving it a higher priority number
than the policy bound globally. For example, set the
priority number for the global policy to one and the virtual server policy to
two. When users log on, NetScaler Gateway runs the global policy scan first and
the virtual server policy scan second.
