Abstract
Systems and methods for verifying a certificate authority are provided. According to one embodiment, a network security device intercepts a session between a client and a server, wherein a secure channel is requested to be established between the client and the server in the session. The network security device captures a digital certificate that is being sent from the server to the client, wherein the digital certificate is used for authenticating the server in connection with establishing the secure channel. The network security device verifies whether a certificate authority (CA) that signs the captured digital certificate is a trusted CA. An action is performed with respect to the session based on a result of the verifying.
