Description

Notes

1.

Use Enhanced Access Security Gateway to log in to Communication Manager, and secure both system administration and maintenance ports. Customers with maintenance contracts have access to the optional password authentication interface program.

-

2.

While attempting to gain access to the system, activate Security Violations Notification (SVN) to report unsuccessful attempts.

Following a security violation, SVN automatically disables:

  • A valid login ID

  • Remote access for a barrier code or an authorization code

-

3.

Use the following to secure trunks:

  • Automatic Route Selection (ARS)

  • Class of Restriction (COR)

  • Facility Restriction Levels (FRL)

  • Alternate Facility Restriction Levels (AFRLs)

  • Authorization Codes

  • Automatic Circuit Assurance (ACA)

  • Forced Entry of Account Codes

For more information about Call Detail Recording, see Avaya Aura® Communication Manager Feature Description and Implementation.

4.

For remote access, use Secure Shell (SSH) as a secure protocol. The SSH capability provides a high level of security during remote access.

-

5.

Activate Enhanced Call Transfer for your voice messaging system, if available. This call facility limits transfers to valid extensions. But you must restrict transfers to extensions that can offer dial tone to the caller, such as screen extensions.
