Logging Into EMA

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 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.

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

https://<hostname>

where <host name> is one of the management IP addresses of the SBC, or the equivalent DNS name. For example, https://10.54.41.8.

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

Security Enhancement to Allow Only One Concurrent EMA Session

This enhancement enables the EMA application (including EMA in platform mode) to disable concurrent user sessions. Once a new session is established, any existing session is terminated immediately. When an EMA user attempts to log in, the system checks for any open sessions with the same username. If any existing user session is identified, that user is immediately logged out from the application and allows the new user to log in to the system.
