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. Communications are intercepted by a client-side proxy before being sent to a recipient designated by an application. The intercepted communication is inspected, and a first connection is determined to be used to send the communication based on the inspection. Finally, before the communication is sent via the first connection, an action is performed by the client-side proxy resulting in an indication that the first connection is compromised. The action may include comparing data associated with the first connection to data associated with known compromised connections. In various embodiments, additional security responses may subsequently be performed by the client-side proxy based on the indication that the first connection is compromised.

Methods and systems for detecting and preventing compromised network connections

Methods and systems provide for preventing a false report of a compromised connection even though a security component receives an indication a connection is compromised, and the security component, by default, would report a compromised connection. In the method, the security component determines that captive portal authentication is enabled for a computing device. The security component requests a response from a server over a connection, with the response indicating that the connection is compromised. However, because captive portal authentication is enabled, the security component does not report the connection as being compromised.
