The Sonus Lawful Intercept (LI) solution supports the following:

  • Encrypts media transferred from Session Border Controller (SBC) to the collection device to avoid security issues.
  • Supports Internet Protocol Security (IPsec) encapsulation of Call Data interface (X3).
  • Enables IPsec encapsulation on the Call Content (media) interface for LI security.
  • Associates IPsec to the IP interface group configured in the CDC.
  • Manages IPsec at the application level.

IPsec - Peer

The object specifies the name of the Internet Key Exchange (IKE) peer database entry that identifies an entry in the IKE Peer Database (IPD). The IPD is a list of remote devices that may become IPsec peers. The IPD establishes the authentication and other phase 1 criteria for the peer-to-peer negotiation to eventually reach an IKE Security Association (SA) between this specific peer and the SBC.

Creating a Peer

  1. On the SBC Configuration Manager page, click All.
  2. On the navigation pane, choose Address Context > IPsec > Peer. Click New Peer.

    The Create New Peer window is displayed.

    Table : Creating New Peer Parameters

     
     Parameter

    Description

    Name

    Specifies the name of the peer you are configuring.

    IP Address V4 or V6

    Specifies the 32-bit IP address of the Peer.

    Protocol

    The SPD traffic selector IP PROTOCOL. Valid values for this parameter are:

    • Ikev1: Indicates the version of IKE protocol. Internet Key Exchange Version 1.
    • Ikev2: Indicates the enhanced version of IKE protocol. Internet Key Exchange Version 2.
    • Any: Indicates either IKEv1 is used or IKEv2 version is used.

    Pre Shared Key

    Specifies the Pre-shared secret with this peer. The Pre Shared Key can be one of the following:

    • A string ranging from 32 to 128 case-sensitive, alphanumeric characters. These characters may only be in the range 0-9, a-z, space, and A-Z
    • A hexadecimal value introduced by "0x" and followed by 16 to 64 hexadecimal digits (0-9, a-f, A-F)

    In either case the given value represents a pre-shared secret between the SBC and the IKE peer. This value is used for mutual authentication for phase 1 negotiation to set up an IKE Security association.

    Sonus recommends using unpredictable (difficult to guess) values. Use a unique value for each IKE peer. This string is never displayed in plain text when using the show commands.
