One-Way and Two-Way Communication Support
MCP supports one-way and two-way communication.
One-Way Communication
NAT traversal has become an increasingly more significant issue in the current
real-world network environment. In order to address this issue, MCP uses one-way
communication. One-way communication has the Control Manager agent initiating
the connection to and polling of commands from the server. Each request is a
CGI-like command query or log transmission. In order to reduce the network impact,
the connection is kept alive and open as much as possible. A subsequent request uses
an existing open connection. Even if the connection is dropped, all connections
involving SSL to the same host benefit from session ID cache that drastically reduces
re-connection time.
Two-Way Communication
Two-way communication is an alternative to one-way communication. It is still
based on one-way communication, but has an extra channel to receive server
notifications. This extra channel is also based on HTTP protocol. Two-way
communication can improve real time dispatching and processing of commands from
the server by the Control Manager agent. The Control Manager agent side needs a
Web server or CGI compatible program that can process CGI-like requests to receive
notifications from Control Manager server.
Single Sign-on (SSO) Support
Through MCP, Control Manager 3.5 now supports single sign-on (SSO) functionality
for Trend Micro products. This feature allows users to sign in to Control Manager
and access the resources of other Trend Micro products without having to sign in to
those products as well.
The following products support SSO with Control Manager 3.5:
•
SeverProtect for Linux version 2.5
