Modular MCU Security Aspects
The MMCU model ensures security is preserved on several levels:
● Salt and Soft Blade APIs - For information on ports see
Summary.
● SIP signaling connections - Both between the Collaboration Server and the Soft Blade, and between
the Soft Blade and the DMA.
● Media - Both between the Collaboration Server and the Soft Blade, and between the Soft Blade and
the endpoint.
When the Administrator wants to accept a Soft Blade currently in Pend Authentication state, it is required
to install a self-signed certificate with the properties:
● Common Name - The host name for which the certificate was generated. Since this is a self signed
certificate, this name is the Soft Blade name as it appears in the Soft Blade monitoring.
● Certificate expiration period - 10 years.
The Administrator then enters the Soft Blade password.
Modular MCU Logger
The Logger aggregates and standardizes the logging at the Soft Blades, or as they are sometimes related
to, Translator Machines. It also allows the Main MCU to gather the Translators/Soft Blades logs from a
centralized gathering point.
Logger Guidelines
● The Main MCU writes logs into the regular Main MCU log file, including API messages sent to the
Soft Blades.
