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 

Spacevars
0 product

shipment. The size of this certificate is 2,000 bytes.

Info
title Note
The BMC is not applicable to Spacevars 0 product2 .

The EMA uses the common Local Cert store of the 

Spacevars
0 series4

(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.

Info
title Note
Spacevars 0 company recommends using only 2,048 bit certificates with release 3.1 and 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

EMA:

https://<hostname>

where, the <host name> is one of the management IP addresses of the

Spacevars
0 product

, or the equivalent DNS name. For example, https://10.54.41.8.

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

Info
title Note
The Spacevars 0 series4 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 Spacevars 0 product 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.

Info
title Note
The Spacevars 0 series4 supports SHA-256 for certificate verification.

Security Enhancement to Allow Only One Concurrent EMA Session

Info
This security enhancement is available beginning with SBC Core version 06.02.00R000.

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

Info
title Note
This feature is applicable to all EMA users (local users, radius users, PKI Certificate based users, and CAC users).
