    Abstract: A method for operating a source node includes receiving a data path validation request command requesting validation of a path associated with a traffic flow identified in the data path validation request command, and determining a first hop sequence in accordance with the path being validated, wherein the first hop sequence is identical to a second hop sequence associated with a non-validation request packet associated with the path being validated. The method also includes generating, by the source node, a validation request packet in accordance with the data path validation request command, the validation request packet comprises route information associated with the first hop sequence, an alert flag set to a specified value, and a path validation header specifying processing performed by nodes receiving the validation request packet, and transmitting, by the source node, the validation request packet in accordance with the route information.

    Abstract: The present disclosure is drawn to systems, methods, and computer-readable media for mitigating cookie-injection and cookie-replaying attacks using a VPN client. The VPN client receives a session request regarding access to a private intranet. In response to the request, the VPN client retrieves cookie deleting criteria, and deletes all cookies which satisfy the cookie deleting criteria. Once all cookies satisfying the cookie deleting criteria are deleted, the VPN client proceeds with the session request.
