Addressing security in an asymmetrical network. At a centralized database, a handshake message is received from a security element that received the message on a first path. A second handshake message is received from a second security element that received the second message on a second path, where the centralized database tracks handshake messages and associations between the messages and communication sessions. A determination is made that the first message is associated with a session. Another determination is made that the second message is associated with the same session. An association between the second message and the first message is stored in the centralized database, based on the associations of the first message and the second message with the same communication session. A determination that the communication session is allowed is stored in the centralized database, based on the association of the second handshake message to the first handshake message.
