NAT
Glossary
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
query or log transmission. To reduce the network impact, the MCP agent keeps
connection alive and open as much as possible. A subsequent request uses an existing
open connection. If the connection breaks, all SSL connections to the same host benefit
from session ID cache that drastically reduces re-connection time.
Patch
A patch is a group of hot fixes and security patches that solve multiple program issues.
Trend Micro makes patches available on a regular basis. Windows patches include a
Setup program, while non-Windows patches commonly have a setup script.
Phish Attack
Phish, or phishing, is a rapidly growing form of fraud that seeks to fool web users into
divulging private information by mimicking a legitimate website.
