Glossary
The Internet Protocol is not designed to be absolutely reliable. The purpose of these
control messages is to provide feedback about problems in the communication
environment, not to make IP reliable.
IntelliScan
IntelliScan is a method of identifying files to scan. For executable files (for example,
.exe), the true file type is determined based on the file content. For non-executable files
(for example, .txt), the true file type is determined based on the file header.
Using IntelliScan provides the following benefits:
• Performance optimization: IntelliScan does not affect applications on the client
because it uses minimal system resources.
• Shorter scanning period: Because IntelliScan uses true file type identification, it
only scans files that are vulnerable to infection. The scan time is therefore
significantly shorter than when you scan all files.
IntelliTrap
Virus writers often attempt to circumvent virus filtering by using real-time compression
algorithms. IntelliTrap helps reduce the risk of such viruses entering the network by
blocking real-time compressed executable files and pairing them with other malware
characteristics. Because IntelliTrap identifies such files as security risks and may
incorrectly block safe files, consider quarantining (not deleting or cleaning) files when
you enable IntelliTrap. If users regularly exchange real-time compressed executable files,
disable IntelliTrap.
IntelliTrap uses the following components:
• Virus Scan Engine
• IntelliTrap Pattern
• IntelliTrap Exception Pattern
IP
"The internet protocol (IP) provides for transmitting blocks of data called datagrams
from sources to destinations, where sources and destinations are hosts identified by
fixed length addresses." (RFC 791)
