Anti spam solutions generally fall under two categories, client-based and server-based. Client-based tools allow each user to configure the software so that it can perform according to individual needs with it’s decentralized approach. Server-based solutions perform spam identification and filtering before legitimate emails are distributed to the intended recipients throughout the network thus reducing the impact that spam has on end-user productivity and on network resources. |

Anti-virus does much more than reactively detect known viruses; it proactively scans for unknown ones too. So, how do scanners really work? The aim of this paper is to reduce some of the confusion around the workings of AV technology, and to clarify what is realistic to expect from AV protection, particularly heuristic analysis.

Spam generates an enormous amount of traffic that is both time-consuming to handle and resource intensive. Apart from that, a large number of organizations have been victims of NDR spam that has an effect similar to a Distributed Denial of Service on the email system. In this paper we provide a technical explanation of NDR Spam and recommend solutions that can prevent or limit exposure to this kind of unsolicited email.

Spammers have now fired a new barrage of image spam using randomized images that appear identical to the human eye, yet appear to be entirely unique to most anti-spam software. Many of the changes to the images contained within spam messages are so subtle that they require a pixel-by-pixel examination of the image in order to detect the differences. Read how Secure Computing effectively addresses this problem.

Mounting an effective defense against spam requires detection techniques that can evolve as quickly as the attacks themselves. Without the ability to automatically adapt to detect new types of threats, an anti-spam solution will always be a step behind the spammers. Proofpoint MLX™ technology leverages the latest machine learning techniques to provide a revolutionary spam detection system.

For most organizations, inbound message volumes (composed primarily of spam email) have increased dramatically, presenting new challenges. How can they most effectively manage this increased message volume and reduce the impact of massive spam storms without “breaking the bank?” Reputation services are a natural component of any email security solution because they can shed large amounts of mail traffic at the connection level.

This white paper explains what makes spam such an unbearable problem and how spamming tactics are evolving daily to beat anti-spam software. The latest tactic is to use the common PDF file format to send image spam. By using PDF attachments to send images instead of embedding them in the body of the email message, spammers have taken the cat-and-mouse game with anti-spam software developers to a new level.

The current risk to computers running non-Windows platforms is small but growing. As Macs and Linux computers become more prevalent within organizations, they are likely to become more of a target for hackers as a way in to the rest of the network and a means of infecting websites. This paper investigates the real threat from non-Windows platforms. It discusses the dangers of them distributing Windows viruses, examines the implications of their growing popularity, and highlights regulatory pressure to protect them.

Reputation systems add a critical first line of advanced protection to help organizations accurately detect and block all types of threats to their messaging, web, and network environments. 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.
