About GroupShield for Exchange

This section introduces McAfee® GroupShield™ 7.0 and describes how it protects your
Microsoft

®

Exchange Server 2003 and Microsoft® Exchange Server 2007 from

potentially harmful, unwanted, and undesirable content.

Topics covered are:

What is GroupShield?

McAfee® GroupShield™ 7.0 software protects Microsoft

®

Exchange Server 2003 and

Microsoft

®

Exchange Server 2007 from virus, phish, spam, unwanted content,

potentially unwanted programs, and banned file types/messages. It also supports
content filtering within the email messages.

How does GroupShield work?

The GroupShield software integrates with Microsoft

®

Exchange Server 2003/2007 to

scan email messages for detections.

8

McAfee® GroupShield™ 7.0 User Guide Introduction

About GroupShield for Exchange

1

Each time, an email message is sent to or received from a source, GroupShield scans
it comparing it with a list of known viruses and suspected virus-like behavior.
GroupShield can also scan for content within the email message using rules and
policies defined within the GroupShield software.

How GroupShield protects Exchange?

GroupShield uses McAfee® Transport Scanner and Microsoft® Virus Scanning API
(VSAPI) to scan all email messages.

The anti-spam, anti-virus, and the content management engine scan the messages and
provide the result to GroupShield 7.0 before being written to the file system or being
read by the Microsoft

®

Exchange 2003/2007 users.

The anti-virus scanning engine and the anti-spam scanning engine compare the email
message with all the known signatures stored within the currently installed virus
definition (

DAT) files and anti-spam rules. The anti-virus engine also checks the message

using the selected heuristic detection methods.

The content management engine searches the email message for banned content as
specified in the content management policies running within the GroupShield
software.

If there are no viruses, banned/unwanted content in the email message, GroupShield
passes the information back to Microsoft

®

Exchange 2003/2007.

In case of a detection, GroupShield takes actions that are defined within its
configuration settings.

Email server protection — McAfee GroupShield

McAfee GroupShield 7.0 integrates with Microsoft

®

Exchange Server 2003/2007 to

protect against viruses that may be transmitted using your corporate email system.

Due to the close integration between your email server and GroupShield anti-virus
solution, GroupShield can do more than just protecting your email server from viruses.
It can:

Note

For Microsoft® Exchange Server 2003 (used as a Bridgehead Server) and Microsoft®
Exchange Server 2007 (with Edge Transport or Hub Transport-only role), GroupShield
uses McAfee

®

Transport Scanner (and not Microsoft® Transport Scanner) to protect the
server. However, for Exchange Server 2003 Mailbox Server and Exchange 2007
MailBox Role, GroupShield provides additional scanning option using Microsoft VSAPI.

Note

The default actions may differ, depending on the installed version of Microsoft

®

Exchange and, where applicable, the chosen scanning method.

 protect the email server from harmful scripts sent within the email system.

 block messages with specific attachments.

 block messages based on words that appear either within the subject line/body of

the message.

 block messages from specific addresses.

How does scanning work?

Central to your GroupShield software is the McAfee® Security scanning engine and the
virus definition (DAT) files. The engine is a complex data analyzer. The DAT files contain
a great deal of information including thousands of different drivers, each of which
contains detailed instructions on how to identify a virus or a type of virus.

The McAfee

®

Security scanning engine works with the DAT files. It identifies the type
of the item being scanned and decodes the contents of that object, so that it
understands what the item is. It then uses the information in the DAT files to search
and locate known viruses. Many viruses have a distinctive signature. There is a
sequence of characters unique to a virus and the engine searches for that signature.

The engine uses a technique called heuristic analysis to search for unknown viruses.
This involves analysis of the object’s program code and searching for distinctive
features typically found in viruses.

Once the engine has confirmed the identity of a virus, it cleans the object as far as
possible. For example, by removing an infected macro from the attachment in which it
is found or by deleting the virus code in an executable file. In some instances, if the
virus has destroyed data, the file cannot be fixed and the engine must make the file
safe so that it cannot be activated and infect other files.

Other areas to protect

The following key areas of your network can be protected by McAfee® Security
products as a part of your integrated virus defense solution:

 Internet gateway protection — Secure Content Management Appliances

The major source of threats to your corporate network comes from Internet traffic,
either through email or by connecting to websites that might contain potentially
harmful code. Secure Content Management Appliances protects the gateway
between your internal networks and the Internet. It prevents infected items from
entering your network through the Internet by scanning all inbound and outbound
traffic between your network and the Internet.

 Document repository protection — McAfee PortalShield

Using computers within corporate environment has made it easy to create
documents that might contain mission-critical information. Several software
vendors produce portal servers to store, index and control your critical documents
in a way that enables them to be easily located when needed. Because these portal
servers are set up to store your critical information, it is important that this
information is also protected. McAfee

®

PortalShield™ integrates with the stores of
these products to provide scanning of such documents each time they are accessed
from, or saved to the store.

 Desktop and file server protection — McAfee VirusScan Enterprise

Not all viruses are transmitted via email. Many can be spread by reading from
physical media, such as diskettes or CDs. Others can spread by using network
shares to copy themselves from one computer to another across your network.

From the viewpoint of somebody trying to attack your corporate network, your file
servers are a good target because many other computers connect to the file
servers. Infecting the file server is more likely to have serious consequences than
infecting a single desktop computer.

The McAfee

®

VirusScan products protect desktop computers and file servers within
your network. As part of your integrated response to virus threats, VirusScan can be
viewed as your last line of defense, protecting each desktop computer and file
server from viruses that might spread using network shares or physical media.

VirusScan is available in versions to protect Microsoft

®

Windows, Unix, Apple
Macintosh computers, as well as all the leading wireless devices that might connect
to your PCs and network.

 Management solution — McAfee

®

ePolicy Orchestrator

With ePolicy Orchestrator, you can manage and update all your McAfee anti-virus
solutions across your network from a single point, ensuring that the engines and the
virus definition (DAT) files are up-to-date and that the suitable policies are in place
to deal with any attacks to your network.

GroupShield Features

GroupShield includes these major features on Exchange Server 2003 and 2007:

 Anti-virus scanning — GroupShield provides the ability to scan for viruses contained

in email messages that are transmitted over Microsoft

®

Exchange SMTP or held

within the Microsoft

®

Exchange Server store.

 Anti-spam scanning — Spam is increasingly becoming an issue within the

workplace. Spam consumes system resources by taking up bandwidth and storage
within your corporate systems and distracts staff from their key job functions
because they have to deal with the unwanted email within their mailboxes.
GroupShield helps you save bandwidth and the storage required by your Microsoft

®

Exchange servers by assigning spam scores to each email messages while
scanning them and by taking the configured action on those messages.

 Anti-phishing — GroupShield is capable of detecting email messages containing

phish that fraudulently tries to obtain personal information. Typically such email
messages request the recipients to click on a link in the email to verify or update
contact details, credit card details or other personal information.

 Content filtering — GroupShield provides the ability to scan for content/text in an:

 email message subject line

 email message body

 email attachment

 File filtering — GroupShield scans an email attachment depending on the file name,

file type, and the file size of that attachment.

 Enterprise rollout, administration, updating and reporting using McAfee

®

ePolicy

Orchestrator and McAfee

®

ProtectionPilot — GroupShield integrates with McAfee®

ePolicy Orchestrator and McAfee

®

ProtectionPilot to provide a centralized method
for rolling out, administering and updating the GroupShield software across your
Microsoft

®

Exchange system. The ability to centrally manage an organization-wide
implementation of the GroupShield software reduces the time required to
administer and update the system.

 Policy Management — The Policy Manager menu option lists different policies that

you can set up/manage in GroupShield. You can specify various policies/actions that
determine how different types of threats are treated when detected. For detailed
information on the policy management, refer to the chapter Policy Manager on

page 105.

 Anti-Phishing Capability — GroupShield for Exchange is capable of detecting email

messages containing phish that fraudulently tries to obtain personal information.

 Capability to detect Packers and Potentially Unwanted Programs — GroupShield for

Exchange is capable of detecting packers that compresses and encrypts the original
code of an executable file.
It also detects Potentially Unwanted Programs that are software programs written
by legitimate companies which may alter the security state or the privacy posture
of a computer on which they are installed.

 Enhanced Anti-Spam Capability — GroupShield for Exchange is capable of detecting

spam or unsolicited bulk email messages sent to multiple recipients, who did not
ask to receive it. It assigns a “spam score” to every email message. You can then
choose to block those messages if they are above a certain score.

 Enhanced Background Scanning options — For Exchange Server 2007, GroupShield

provides enhanced background scanning options. During this type of scanning, not
all the email messages are scanned when accessed. This reduces the workload of
the scanner. For more information, refer to the sub topic For Exchange Server 2007

on page 165.

 Centralized Scanner, Filter Rules and Enhanced Alert Settings — Using Scanners,

you can configure the scanner-related settings that a policy can apply when
scanning items.
In File Filtering Rules, you can set up rules that apply to file name, file type, and file
size. You can use the alert editor to customize the text of an alert message using
the Style, Font, Size, and Token menus.

 Time based scanning and actions — GroupShield for Exchange enables scanning

emails at convenient times or at regular intervals. You can schedule regular scan
operations when the server activities are comparatively low and when they do not
interfere with your work.

 Enhanced MIME Scanning — MIME (Multipurpose Internet Mail Extensions) is a

communications standard that enables the transfer of non-ASCII formats over
protocols (like SMTP) that supports only 7-bit ASCII characters. GroupShield enables
you to specify how such MIME messages are handled.

 Buffer Overflow protection using VirusScan Enterprise version 8.5i — A buffer

overflow is an anomalous condition where a process attempts to store data beyond
the boundaries of a fixed-length buffer. This results in extra data, overwriting the
adjacent memory locations. Enabling Buffer Overflow Protection prevents this
condition. GroupShield has the provision of buffer overflow protection. For more
information, refer to Buffer Overflow Protection on page 30.

 Enhanced Quarantine Management

 Local Quarantine Management — Detected Items can be quarantined. You can

specify the local database to be used as a repository for quarantining email
messages. You can also configure maintenance settings for the local quarantine
database.

majority of permissions should be applied to groups, rather than individual users. This

 Buffer Overflow Protection

 McAfee Anti-Spam for GroupShield

Buffer Overflow Protection

Buffer overflow is an attack technique that exploits a software design defect in an
application or process to force it to execute code on the computer. Applications have
fixed-size buffers that hold data. If an attacker sends too much data or code into one of
these buffers, the buffer overflows. The computer then executes the code that
overflowed as a program. As the code execution occurs in the security content of the
application (which is often at a highly-privileged or administrative level), intruders gain
access to execute commands not usually accessible to them. An attacker can use this
vulnerability to execute custom hacking code on the computer and compromise its
security and data integrity.
