    IDP SSL Overview

    Secure Sockets Layer (SSL), also called Transport Layer Security (TLS), is a protocol suite for Web security that provides authentication, confidentiality and message integrity. Authentication guards against fraudulent transmissions by enabling a Web browser to validate the identity of a webserver. Confidentiality mechanisms ensure that communications are private. SSL enforces confidentiality by encrypting data to prevent unauthorized users from eavesdropping on electronic communications. Finally, message integrity ensures that the contents of a communication have not been tampered with.

    Each SSL session begins with a handshake during which the client and server agree on the specific security key and the encryption algorithms to use for that session. At this time, the client also authenticates the server. Optionally, the server can authenticate the client. Once the handshake is complete, transfer of encrypted data can begin.

    Juniper Networks provides Intrusion Detection and Prevention (IDP) SSL inspection that uses the SSL protocol suite consisting of different SSL versions, ciphers, and key exchange methods. Combined with the Application Identification feature, the SSL Inspection feature enables SRX Series devices to inspect HTTP traffic encrypted in SSL on any port. The following SSL protocols are supported:

    • SSLv2
    • SSLv3
    • TLS
