Malicious email volume is rising at an alarming rate, both in terms of number and message size. Spam is now incorporated into the propagation strategies of blended malware attacks, and increasingly sophisticated techniques are outwitting first-generation email security solutions.

In simplest terms, deploying a reputation service at the network edge is analogous to having a peephole in the front door of your house. You let in people you know and trust, question the ones you don’t know, and shun the ones who look suspicious. Just by taking these simple measures you reduce your risk.

This paper will discuss the issues surrounding the protection of key corporate assets such as intellectual property, protected trade secrets, customer information, and regulated content. There are four major threat vectors:

This document outlines how hackers are exploiting vulnerabilities in email systems, and describes the widely available hacking tools they use.

In simplest terms, deploying a reputation service at the network edge is analogous to having a peephole in the front door of your house. You let in people you know and trust, question the ones you don’t know, and shun the ones who look suspicious.

Just by taking these simple measures you reduce your risk. Similarly, organisations can save a lot of money by filtering the bad traffic at the edge of the network using reputation based services.

After examining this document, the reader will not only understand the importance of securing the network edge with a global reputation service but will also appreciate the huge savings that can be realised.

The Storm worm, launched January 2007, was the first comprehensive solution for Internet fraud and attacks. Studying Storm helps us understand the current state-of-the-art hacking techniques and provides valuable lessons for the future. Storm’s authors have been able to:

• Perfect social engineering
• Abuse unsecured Web 2.0 technologies
• Defend itself from attacks and attempts to shut it down
• Create new types of exploits

This paper will dissect some of the techniques used by Storm, take a look at what this portents for the future, and discuss what technologies can be used to protect against these threats.
