Overview
address of the Media Gateway as the desired gateway, or they may rely on the VoIP Address
Translator to address the Media Gateway using the gateway prefix configured on the Media
Gateway.
1.4 Security
The Media Gateway supports two kinds of security:
• Access Security
• Data Security
1.4.1 Access Security
Access to the Media Gateway is secured by requiring a user name and password to login to the
gateway. The user name and password are required for all interfaces of the Media Gateway (Web
interface, serial interface, and telnet interface).
1.4.2 Data Security
Data security for the Media Gateway includes the use of various secure protocols when
transmitting and receiving data. The Media Gateway supports security for three types of data:
• HTTP security - Data transmitted between the Media Gateway and a Web browser. To secure
HTTP, the Media Gateway uses HTTPS protocol.
• Call Control security - Data used to setup and tear down a call. To secure Call Control, the
Media Gateway uses Transport Layer Security (TLS) on top of SIP.
• Voice security - The actual conversation once a call is connected. To secure voice, the Media
Gateway uses SRTP.
Because, for security, the HTTPS and TLS protocols also require digital identity certificates (e.g.
public key certificates), Certificate Configuration and Management is also provided by the Media
Gateway.
For additional information about how the Media Gateway supports security, see Chapter 7, “Data
Security”.
1.5 Web Interface
The Web interface is accessed from a workstation on the Ethernet connected to the LAN connector
on the rear panel of the Media Gateway. Communication is established by starting a Web browser
at the workstation and entering the IP address of the Media Gateway. The unit's Web interface is
password protected and the password can be changed by the system administrator. Figure 5 shows
a typical Web interface page for a DMG1000 unit and Figure 6 shows a typical Web interface page
for a DMG2000 unit.
