The security of network connections on a computing device is protected by detecting and preventing compromise of the network connections, including man-in-the-middle (MITM) attacks. Active probing and other methods are used to detect the attacks. Responses to detection include one or more of displaying a warning to a user of the computing device, providing an option to disconnect the network connection, blocking the network connection, switching to a different network connection, applying a policy, and sending anomaly information to a security server.

Methods and systems for detecting and preventing network connection compromise

A method and device to manage addresses in a network includes receiving a request for a network address from a client computer at a proxy computer, relaying the request to an address server, receiving an address offer message from the address server at the proxy computer, storing an server identifier of the address server from the offer message, replacing the server identifier of the address server in the offer message with an address identifier of the proxy computer to produce an altered offer message, and sending the altered offer message to the client computer.
