Table 1-1 Definitions (continued)

Term Description

network user

An unauthenticated remote user or process sending information to the

workstation through a network protocol; this role only has the authority to send

information through the appliance from either the Internet or the internal

network.

packers

Compression tools that compress files and change the binary signature of the

ecutable. They can be used to compress Trojans and make them harder to

detect.

Perl DBI

Perl DBI (database interface) is a database interface for the Perl programming

language. It is used within the McAfee Email Gateway Appliance in the logging

subsystem for the purposes of accessing the database housing audit records.

phishing

This category includes sites that typically arrive in hoax email established only to

steal user account information. These sites falsely represent themselves as

legitimate company websites in order to deceive and obtain user account

information that can be used to perpetrate fraud or theft.

POP3 Post Office Protocol 3

potentially

unwanted

progr

ams (PUPs)

A program that performs some unauthorized (and often harmful or undesirable)

acts such as viruses, worms, and Trojan horses.

quarantine

Enforced isolation of a file or folder — for example, to prevent infection by a virus

or to isolate a spam email message — until action can be taken to clean or

remove the item.

scanning engine The mechanism that drives the scanning process.

signature The description of a virus, malware, or attack methodology.

SMTP 250

command

Requested mail action okay, completed.

spam score

A rating system used to indicate the likelihood that an email message contains

spam. The higher the score allocated to a message, the more likely it is to be

spam.

spyware

This category includes URLs that download software that covertly gathers user

information through the user's Internet connection, without his or her knowledge,

usually for advertising purposes. This might be considered a violation of privacy

and might have bandwidth and security implications.

transparent mode

In either transparent router mode or transparent bridge mode, the

communicating devices are unaware of the interv

ention of the appliance — the

appliance's operation is transparent to those devices.

Trojan

An application that either pretends to have, or is described as having, a set of

useful or desirable features, but actually contains a damaging payload. Trojan

horses are not technically viruses because they do not replicate.

virtual appliance A virtual machine image designed to run on a virtualization platform.

virus

An application that is capable of replicating with little or no user intervention, and

the replicated program(s) also replicate further.

whitelist

A list of email addresses or domains you created that the anti‑spam module

treats as non‑spam. When the anti‑spam module detects an incoming message

from an address or domain on the whitelist, it immediately assigns a high

negative score to that message.

worm A virus that spreads by creating duplicates of itself on other driv

es, systems, or

networks.
