1. A method for adaptive online system access control, the method comprising:
obtaining, by a system access control monitor of a client system, from a network interface unit of the client system, a protocol data unit sent to the client system by an external device, wherein the protocol data unit is associated with a communication context, and wherein obtaining the protocol data unit includes:
prior to other components of the client system accessing the protocol data unit:
identifying, as a current access score for the protocol data unit, a sum of a previous access score associated with the communication context and a modifier value determined for the protocol data unit; and
responsive to determining that the current access score is less than an access threshold value, preventing the other components of the client system from accessing the protocol data unit.
