Evolution of Email

Email becoming important

Volumes growing

A desktop experience

Virus/Spam annoyance

Plaintext email

Basic archiving

Downtime common

More important than phone

Volumes growing faster

Desktop + mobile

Viruses can shut down businesses

Rich email, large attachments

Policy & regulatory compliance

High availability expected but operations are complex & costly

Cornerstone of collaboration

Volumes growing exponentially

Any networked device

Viruses impacting devices beyond server & PC

Integrated communications

Ubiquitous privacy, security & compliance requirements

High availability with simplified operations & reduced costs

Mid to Late 90’s TomorrowToday

Growth of Spam

Still the No1 driver for Content Security From 8 % of all Email in 2001 to 60%+ of all

Email in 2004 Average of 60% of all company Email is Spam Some companies as high as 95.8% NetiQ receives up to 9.2 Million Email per 24hrs

69% Spam, 4% Virus infected

Today 40% of all Spam sent by Zombie PC’s SoBig, MyDoom, Bagle all contained code

Other Internet Attacks…

What is Spy-ware? Hacker Tools

defined as programs that are intentionally run by a hacker, usually in the hacker's machine. All such tools have interfaces through which the hacker interacts with the program

Key Loggers Application running in the background recording all the keystrokes

Remote Administration Tools A Remote Administration Tool, or RAT, is a Trojan that when run, provides an attacker with the

capability of remotely controlling a machine via a "client" in the attacker's machine, and a "server" in the victim's machine

Spy-ware Any product that employs a user's Internet connection in the background without their

knowledge, and gathers/transmits info on the user or their behavior Spy-ware Cookies

Any cookie that is shared among two or more unrelated sites for the purpose of tracking a user's browsing and/or gathering and/or sharing information which many users regard as "private.

Trojans Unwanted software which runs in a user's machine, as an agent of the attacker, without user

awareness Worms

A program that propagates by attacking other machines and copying itself to them

Denial of Service

NETIQ bought two new companies to complement the Web Trends business - Web Position and First Place software in May.

IT migrated from an old Unix based system (that did include Marshal - but all mail was handle by Unix mail gateways 1st) to 3 dual proc Windows 2003 servers running Marshal 6.0

The "business" was anxious that both these companies were integrated into the NETIQ mail system before the start of the next calendar month (June). This migration would involve changing their MX records to point to NETIQ.

Denial of Service

Our mail volume increased immediately after integration but just before month end First Place got hit by email "storm".

In 24hrs we processed over 11 million messages, stayed up(!) and got through month end. If email had gone deals could not have been closed !!! (the process in SAP is reliant on an automated email process - no rev rec otherwise).

Denial of Service

When we had previously been targeted by email "storm" (prior to the installation of Marshal) we had to ask our ISPs to stop sending us mail while we rebuilt out trashed systems. Don't have a financial impact of that episode but our CIO did change a few months later ;-).

Viruses, viruses, viruses!!!

The virus problem remains
