AUTONOMOUS PILICY ENFORCEMENT POINT CONFIGURATION FOR ROLE BASED ACCESS CONTROL
An example profiler device includes one or more processors implemented in circuitry and configured to monitor network traffic entering and exiting the protected network zone; identify one or more endpoints that interface with the protected network zone; compare network traffic characteristics of network traffic associated with the endpoints to network traffic characteristics of known device types to determine device types corresponding to the endpoints; assign one or more network policies to the identified endpoints according to the determined device types; and distribute data representing the assigned network policies to a policy enforcement point (PEP) device to cause the PEP device to enforce the network policies on network traffic, associated with the identified endpoints, entering and exiting the protected network zone.
1 . A method of providing network security, the method comprising:
monitoring, by a profiler unit that determines policies for protecting a protected network zone, network traffic entering and exiting the protected network zone;
identifying, by the profiler unit, one or more endpoints that interface with the protected network zone;
comparing, by the profiler unit, network traffic characteristics of network traffic associated with the endpoints to network traffic characteristics of known device types to determine device types corresponding to the endpoints;
assigning, by the profiler unit, one or more network policies to the identified endpoints according to the determined device types; and
distributing, by the profiler unit, data representing the assigned network policies to a policy enforcement point (PEP) device to cause the PEP device to enforce the network policies on network traffic, associated with the identified endpoints, entering and exiting the protected network zone.
2 . The method of claim 1 , further comprising:
assigning one or more user role policy elements to the endpoints; and
distributing the user role policy elements to the PEP device.
3 . The method of claim 1 , wherein identifying the one or more endpoints comprises determining, for the network traffic associated with each of the endpoints, one or more of a source media access control (MAC) address, a destination MAC, a communication protocol, an authentication protocol, or a Network Basic Input/output System (NetBIOS) address.
4 . The method of claim 1 , wherein distributing the data representing the assigned network policies comprises distributing data associating identifiers of the identified endpoints with the network policies assigned to the identified endpoints.
5 . A profiler device comprising one or more processors implemented in circuitry and configured to:
monitor network traffic entering and exiting the protected network zone;
identify one or more endpoints that interface with the protected network zone;
compare network traffic characteristics of network traffic associated with the endpoints to network traffic characteristics of known device types to determine device types corresponding to the endpoints;
assign one or more network policies to the identified endpoints according to the determined device types; and
distribute data representing the assigned network policies to a policy enforcement point (PEP) device to cause the PEP device to enforce the network policies on network traffic, associated with the identified endpoints, entering and exiting the protected network zone.
6 . The profiler device of claim 5 , wherein the one or more processors are further configured to:
assign one or more user role policy elements to the endpoints; and
distribute the user role policy elements to the PEP device.
7 . The profiler device of claim 5 , wherein to identify the one or more endpoints, the one or more processors are configured to determine, for the network traffic associated with each of the endpoints, one or more of a source media access control (MAC) address, a destination MAC, a communication protocol, an authentication protocol, or a Network Basic Input/output System (NetBIOS) address.
8 . The profiler device of claim 5 , wherein to distribute the data representing the assigned network policies, the one or more processors are configured to distribute data associating identifiers of the identified endpoints with the network policies assigned to the identified endpoints.
9 . A computer-readable storage medium comprising instructions that, when executed, cause a processor to:
monitor network traffic entering and exiting the protected network zone;
identify one or more endpoints that interface with the protected network zone;
compare network traffic characteristics of network traffic associated with the endpoints to network traffic characteristics of known device types to determine device types corresponding to the endpoints;
assign one or more network policies to the identified endpoints according to the determined device types; and
distribute data representing the assigned network policies to a policy enforcement point (PEP) device to cause the PEP device to enforce the network policies on network traffic, associated with the identified endpoints, entering and exiting the protected network zone.
10 . The computer-readable storage medium of claim 9 , further comprising instructions that cause the processor to:
assign one or more user role policy elements to the endpoints; and
distribute the user role policy elements to the PEP device.
11 . The computer-readable storage medium of claim 9 , wherein the instructions that cause the processor to identify the one or more endpoints comprise instructions that cause the processor to determine, for the network traffic associated with each of the endpoints, one or more of a source media access control (MAC) address, a destination MAC, a communication protocol, an authentication protocol, or a Network Basic Input/output System (NetBIOS) address.
12 . The computer-readable storage medium of claim 9 , wherein the instructions that cause the processor to distribute the data representing the assigned network policies comprise instructions that cause the processor to distribute data associating identifiers of the identified endpoints with the network policies assigned to the identified endpoints.
