Abstract: A system for generating virtual private network (VPN) sessions from VPN server log messages uses and displays a VPN sessions table in which each row contains attributes of a corresponding VPN session. Processing of a log message causes a session to be generated when there is no ACTIVE session in the table for a username extracted from a log message. A time extracted from the log message is stored as the session start time and as a temporary end time associated with the session. If a gap between a temporary end time and a time extracted from a log message for the associated ACTIVE session is less than a threshold amount, the temporary end time is set to the extracted time. If the gap is equal to or exceeds the threshold, the status of the session is changed from ACTIVE to CLOSED, and a new ACTIVE session is generated.

Abstract: A private overlay network is introduced into an existing core network infrastructure to control information flow between private secure environments. Such a scheme can be used to connect a factory automation network linking operations devices to a corporate network linking various business units, with enhanced network security. Such a connection can be facilitated by introducing into the existing infrastructure a set of industrial security appliances (ISAs) that work together to create an encrypted tunnel between the two networks. The set of ISAs can be scalable to overlay differently sized core networks, to create the private overlay network. Connections to the private overlay network can be managed by the ISAs in a distributed fashion, implementing a peer-to-peer dynamic mesh policy. The industrial security system disclosed may be particularly advantageous in environments such as public utility systems, medical facilities, and energy delivery systems.

In this manner, the origin leverages the content distributor distributed platform architecture to shield itself from attack. Based on the origin signaling, the content distributor rate limits, blocks, redirects, or performs other attack protections to reduce the load on the origin server.
