MCP Agent
Trend Micro Management Communication Protocol (MCP) is Trend Micro's next 
generation agent for managed products. MCP replaces Trend Micro Management 
Infrastructure (TMI) as the way Control Manager communicates with OfficeScan. MCP 
has several new features:
• Reduced network loading and package size
• NAT and firewall traversal support
• HTTPS support
• One-way and Two-way communication support
• Single sign-on (SSO) support
• Cluster node support
Mixed Threat Attack
Mixed threat attacks take advantage of multiple entry points and vulnerabilities in 
enterprise networks, such as the “Nimda” or “Code Red” threats.
NAT
Network Address Translation (NAT) is a standard for translating secure IP addresses to 
temporary, external, registered IP address from the address pool. This allows trusted 
networks with privately assigned IP addresses to have access to the Internet. This also 
means that you do not have to get a registered IP address for every machine in the 
network.
NetBIOS
Network Basic Input Output System (NetBIOS) is an application program interface 
(API) that adds functionality such as network capabilities to disk operating system 
(DOS) basic input/output system (BIOS).
One-way Communication
NAT traversal has become an increasingly more significant issue in the current 
real-world network environment. To address this issue, MCP uses one-way 
communication. One-way communication has the MCP agent initiating the connection 
to, and polling of commands from, the server. Each request is a CGI-like command
