This profile specifies the type and behavior of security mechanism to apply to the Access Solution acting as P-CSCF.

Note

When configuring Sip Security Profile on a particular SIP Trunk Group, ensure Authcode Headers transparency flag (see Common Ip Attributes - Transparency Flags) is not enabled on the same Trunk Group.

Note

When configuring a SIP Security Profile in P-CSCF mode, a Sip Security Mechanism is required.


IMPORTANT

Ribbon recommends using the Transparency Profile to configure transparency on the SBC Core for new deployments, as well as applying additional transparency configurations to existing deployments. Do not use IP Signaling Profile flags in these scenarios because the flags will be retired in upcoming releases.

Refer to the SBC SIP Transparency Implementation Guide for additional information.

SIP Security Profile

Parameter

Description

Name

Specifies the user name of this Security Profile.

Sbx Sec Mode

Use this parameter to define the SBC security mode for this SIP Security Profile. The options are:

  • Sbc-pcscf: SBC acts as integrated SBC+PCSCF mode.
  • Sbc-only: SBC-only mode. SBC disregards the configured security mechanism (ipsec-3gpp or tls) in the profile, if any.

When Sbx Sec Mode is configured as sbc-only, you must configure a Transparency Profile for following headers in an egress trunk group.

Refer to SIP Security Profile - CLI, Command Examples section to know more on how to configure a Transparency Profile.

Refer to P-CSCF Security Mechanisms to know the functionality of this feature.

Force Client
Security

If Enabled, while selecting the Security Mechanism, the precedence is given to the order of occurrence of mechanism-name values in the Security-Client header.

The options are:

  • Disabled (default)
  • Enabled

Reject Sec Unsupported Request

Enable this flag to reject the incoming REGISTER when it does not contain "sec-agree" header value (in Require or Proxy-Require headers) or does not contain any supported mechanism-name (ipsec-3gpp) in "Security-Client" header.
Use default setting "Disabled" to process messages using "Digest without TLS" security mechanism.

  • Disabled (default)
  • Enabled
Encryption Preference

Provides encryption preference for SIP Security Profile.

The available options are:

  • Always-encrypt—Use this option to reject REGISTER requests if the UE offers a NULL encryption algorithm. 
  • None (default)—If this option is configured the SBC compares the UE's offer of encryption algorithms with the list of supported encryption algorithms, and selects the first matched entry in the 401 response for the REGISTER request. The SBC accepts the NULL encryption algorithm if it is the first one in the UE's offer.
  • Null-forced— Use this option to enforce NULL encryption irrespective of what encryption algorithm offered by the UE. The SBC acting as a Proxy For Call Session Control Function (P-CSCF) always disables encryption.
