The Cost of E-Mail Security Breaches

“In 2001, e-mail viruses, worms and trojans caused worldwide damages worth $13.2 billion”

Computer Economics, January 2002

What Are Businesses Doing About It?

“According to Forrester Research, an average of .0024% of revenue is being spent on IT security. That’s a little bit less than what most companies spend on coffee.”

-Richard A. ClarkeChair of the President’s criticalInfrastructure Protection Board

and Special Advisor to thePresident for CyberSpace Security

Put GWAVA on the Case

GWAVA scrutinizes every message that passes through your GroupWise MTAs…

• Providing eSecurity Policy Management for Virus protection Spam prevention Content control Bandwidth control

How GroupWise Works

Traditional file scanning is useless because GroupWise stores all messages in an encrypted database

A virus can move freely around your GroupWise system because it cannot be scanned

Other products that claim to protect GroupWise are really designed generically for SMTP—It’s like posting a guard outside your front door, but who’s watching the interior and your back door and your windows?

This image depicts a virus (green line) successfully traveling from “LA 2” to “NY 2”;It is never scanned because it never passes through GWIA—This system is not fully protected because scanning only occurs at the edge of your network

Urban Myth…

“Wait a second, we don’t use Outlook. Aren’t we immune to viruses?”

—What many of you are thinking

Security Backdoors—MAPI

Outlook and Office can access the GW address book via MAPI

Example:Badtrans was one of the most successful viruses in 2001—It spread using MAPI

Security Backdoors—MAPI Top 50

Here’s a short list of MAPI-capable viruses:

Security Backdoors— Web Mail




How many people check their personal web mail from work?

Security Backdoors— Blended Viruses




NIMDA was a blended virus that also attacked web servers and penetrated networks through browsers




MS Outlook is embedded in recent versions of Windows and may be in use on your network… whether you allow it or not

Security Backdoors— (un)Authorized Outlook Usage

Since GWAVA was designed from the ground up for GroupWise, it can run as a NetWare Loadable Module™ on all of your Message Transfer Agent servers. Both Internet AND inter-office traffic must pass through your MTAs. It’s like having a guard in every hallway of your building. GWAVA can prevent a virus from spreading beyond a single post office.

In this image viruses cannot travel to other post offices because they are scanned by GWAVA when they pass through the MTA

How GWAVA Works

VirusVirusblockeblockedd

As messages pass through the MTA, GWAVA temporarily moves the message (and attachments) to a quarantine zone, where they can be scanned for policy violations

Since GWAVA essentially exposes attachments in the quarantine zone, GWAVA makes it possible for you to use your existing AV NLM to scan the attachment
