How often should a WPA2-Enterprise PMK be rekeyed in a high security, large corporate network?
The Pairwise-Master-Key (PMK) is the foundation key of encrypted communication on nearly all WPA WiFi networks, including WPA2-Enterprise networks.
Typically, the PMK rekey interval for personal networks is around 2-3 hours.
But how often should the PMK be rekeyed in a large corporate WPA2-Enterprise network, where security is a priority?
Does the 2-3 hour rule apply here, too?
