HTTPS Support

The EMA GUI is available via TLS-secured (https) access either directly through port 443 or indirectly through port 80 to 443. ACL rules are not applicable to prevent unsecured (http) access.

A sample X.509 certificate, which is a copy of the BMC and the EMA Platform Mode certificate, is shipped along with the SBC shipment. The size of this certificate is 2,000 bytes.

The BMC is not applicable to SBC SWe.

The EMA uses the common Local Cert store of the SBC Core (used also for SIP/TLS) rather than having its own separate certificate store. The operator may replace that sample certificate at any time. The replacement mechanism is implemented with post installation/upgrade scripts.

Certificates with RSA keys up to 4,096 bits are supported.

Sonus recommends using only 2,048 bit certificates with release 3.1. Sonus discourages the use of 4,096 bit certificates in 3.1 due to anticipated upgrade issues with the current software.

Enter the following URL in the browser to access the SBC EMA:

https://<hostname>

where, the <host name> is one of the management IP addresses of the SBC, or the equivalent DNS name. For example, https://10.54.19.17

The EMA uses a self-signed certificate which may produce a warning message by Internet Explorer and Firefox. These messages may be ignored.

The SBC Core is delivered with sample self-signed X.509 certificates. Please be aware that even though these sample certificates will allow you to use HTTPS to access the SBC from EMA, BMC and EMA Platform Mode interfaces, using this protocol with the sample certificates is not a truly secure access method. If your organization requires a more secure access, refer to Generating PKI Certificates.

The SBC Core supports SHA-256 for certificate verification.
