Quarantine Status The quarantine status depends on the health condition of the client computer. Three states are provided for
policy based network access, these include:
• Not Restricted
Full network access is granted when the health evaluation result returns the health state Healthy .
• Probation
When the client computer does not meet the configured health requirements, it will enter probation
state. In this state he is not restricted in order to contact network resources necessary to meet all health
requirements. If the following health evaluation does not return a
Healthy state he will enter restricted
network access mode.
• Restricted
If restricted network access is active, the Client will activate the quarantine rule set assigned by the
Access Control Server.
Note:
It is possible to configure two quarantine rule sets, one for when the client computer does not meet the
health requirements and is unhealthy. The other for when the client computer is untrusted because no rule
is defined for it.
