Abstract
When a network element attempts to establish a session with another network element, a security verification agent may be activated in one or both network elements. The security verification agents, such as front-end processors, virtual network functions, or other software agents, may reside in each of the network elements.
Claims20
A method comprising:
- responsive to a control plane request associated with a first core network element:
- pausing processing of the control plane request by a second core network element while performing a security verification;
- and
- activating, by the second core network element, a security agent to generate a query for the security verification;
- and
- determining, by the second core network element, a validation status of the first core network element via a security verification device according to the query for the security verification, wherein the query includes a current value associated with the first core network element, and wherein the security verification device compares the current value with a second value representing an unmodified state of the first core network element.

A non-transitory computer readable storage medium storing computer executable instructions that when executed by a processing system including a processor cause the processing system to perform operations comprising:
- responsive to a control plane request associated with a first core network element:
- pausing processing of the control plane request by a second core network element while performing a security verification;
- and
- activating a security agent of the second core network element to generate a query for the security verification;
- and
- determining a validation status of the first core network element via a security verification device according to the query for the security verification, wherein the security verification device compares a current value associated with the first core network element with a second value representing an unmodified state of the first core network element.
3 more elements
A device, comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- responsive to a control plane request associated with a first core network element:
- pausing processing of the control plane request by a second core network element while performing a security verification;
- and
- activating a security agent of the second core network element to generate a query for the security verification;
- and
- determining a validation status of the first core network element from a security verification device according to the query for the security verification, a current value associated with the first core network element, and a second value representing an unmodified state of the first core network element.
