SDP Anonymization
In order to provide an added measure of security, the Oracle® Enterprise Session Border Controller’s topology-hiding capabilities include SDP anonymization. Enabling this feature gives the Oracle® Enterprise Session Border Controller the ability to change or modify certain values in the SDP so that malicious parties will be unable to learn information about your network topology.
To do this, the Oracle® Enterprise Session Border Controller hides the product-specific information that can appear in SDP o= lines and s= lines. This information can include usernames, session names, and version fields. To resolve this issues, the Oracle® Enterprise Session Border Controller makes the following changes when you enable SDP anonymization:
- Sets the session name (or the s= line in the SDP) to s=-
- Sets the username in the origin field to -SBC
- Sets the session ID in the origin field to an integer of incrementing value
Note that for mid-call media changes, the session identifier is not incremented.
To enable this feature, you set a parameter in the media manager configuration.
