Security; Registration And Authentication - Avaya 1600 Series Administrator's Manual

Network Requirements

Security

For information about toll fraud, see the DEFINITY
documents on the Avaya support Web site. The 1600 Series IP Telephones cannot guarantee
resistance to all Denial of Service attacks. However, there are checks and protections to resist
such attacks while maintaining appropriate service to legitimate users.
All 1600 Series IP Telephones that have WML Web applications support Transport Layer
Security (TLS). This standard allows the telephone to establish a secure connection to a HTTPS
server, in which the upgrade and settings file can reside. This setup adds security over another
alternative.
You also have a variety of optional capabilities to restrict or remove how crucial network
information is displayed or used. These capabilities are covered in more detail in
Chapter 5: Server
