Network Access Control (NAC)
NAC is a service offered to departments that enable network services to assess the posture of an end system before allowing it to have full network access. This assessment can be done via a combination of external scans (authenticated and unauthenticated) and an installed assessment agent.
-Generally, but not always, networking can craft checks that suit the needs of the department.
-Generally, but not always, assessment of devices connecting to the wireless network is not included and considered out of scope.
-Assessment of VPN connections, or connections off of campus, is out of scope.
Students, faculty, and staff.
Once a department is configured for NAC, machines requiring assessment may be required to either download an agent through a web portal, or have that agent pushed to them via active directory. Those methods are up to the discretion of the requesting department IT staff.
Directly connected machines on the wired network. For agent based assessment: Most windows and Apple Operating systems. For external assessment: All operating systems.

SLA Response Times
For client submitted issues:
- Critical = 15 minutes, 24x7 *
- Important = 3 hour, 8-5 M-F (excluding holidays)
- General = 24 hours business hours, 8-5 M-F (excluding holidays)
- Our services are monitored 24x7x365.
* Critical tickets require that the client be reachable via phone and that the phone number is documented in the ticket. Any client that does not respond to phone queries will have their ticket downgraded to important. If the issue requires networking to rely on an outside vendor for assistance, we may be unable to meet the posted response times.
For service related issues:
We are notified upon most service failures, and treat service outages as critical events require the service managers / process owners to begin working on the problem within 15 minutes of notification unless we deem the problem to be low impact (little to no client impact)

Upgrades to the service require a change notice and approval through the CAB. Upgrades normally happen twice a year, and we do our best to schedule this changes during periods of inactivity (between semesters, for example). Periodically agents will need to be updated, and we will work with the departments to schedule an appropriate time to publish the updates. Policy changes (changes to requirements for end system posture) do not require a change notice and can be done at any time.
In addition, this service is governed under the ITS Change Plan process. Please see this site for details:
