What Is Posture Validation?
Posture refers to credentials or attributes associated with an endpoint device, such as a smartphone or a computer. Posture validation is a network process that determines whether an endpoint has the required security to access a network.
-
Function
-
An endpoint communicates its posture attributes to the security control, which initiates a secure connection between the two. It then evaluates the attributes by applying a set of network rules to determine if the endpoint can safely access the network.
Features
-
The network assigns a posture token to an endpoint to represent the state of its security. For example, a posture token may describe an endpoint as "healthy," "infected" or "unknown." Posture tokens combine with traditional user authentication to provide a complete assessment of the security level of the endpoint and user.
-
Considerations
-
A network administrator can set up posture validation policies within the access control server or he can set up policies on an external network access control or posture validation server. He can also choose a combination of the two, where an external server will take precedent in validation and must approve a validation request before an internal server will perform posture validation.
