Max Sessions

Max Sessions is a useful feature for organizations that need to limit the number
of concurrent sessions available to either a user or a group:

User Max Sessions—For example, an Internet service provider can limit
each account holder to a single session.

Group Max Sessions—For example, an enterprise administrator can allow
the remote access infrastructure to be shared equally among several
departments and limit the maximum number of concurrent sessions for all
users in any one department.

In addition to enabling simple User and Group Max Sessions control,
Cisco Secure ACS enables the administrator to specify a Group Max Sessions
value and a group-based User Max Sessions value; that is, a User Max Sessions
value based on the group membership of the user. For example, an administrator
can allocate a Group Max Sessions value of 50 to the group “Sales” and also limit
each member of the “Sales” group to 5 sessions each. This way no single member
of a group account would be able to use more than 5 sessions at any one time, but
the group could still have up to 50 active sessions.

Dynamic Usage Quotas

Cisco Secure ACS enables you to define network usage quotas for users. Using
quotas, you can limit the network access of each user in a group or of individual
users. You define quotas by duration of sessions or the total number of sessions.
