1.5. Post-Admission NAC

Post-Admission NAC differs from Pre-Admission as it relates to the point at which assessment takes place. Post-Admission takes place as it is described, after admission to the network has been granted.

This functionality is important because a device's security posture can change from the time it was first granted access to the network. In addition, the behavior of that device once it is on the network can be cause for restriction.

Figure 1-2 shows a graphical representation of Post-Admission NAC.
