Abstract
Conventional anti-virus software relies on a staff of researchers to isolate and analyze
viruses, identify them with a fingerprint, and then write and test code and rules to block
them. This process takes up to 24 hours and often blindly blocks many legitimate messages
with attached executable code. In contrast, Cloudmark’s Global Threat Network.
uses a fingerprinting algorithm to identify each incoming message, combined with a
reputation-based, trusted community of real-time users to identify malicious viruses. Using
the Cloudmark Trust Evaluation System. (TES), Cloudmark is able to let trustworthy,
credible users identify viruses. Cloudmark’s virus fingerprinting algorithm automates the
time-intensive “reverse engineering” analysis of conventional technologies allowing its
system to identify and squelch new worms and virus strains in real time. The Cloudmark
technology is language-agnostic, format-agnostic, representation-agnostic, and protocol-
agnostic - making it particularly suited to combat all forms of malicious content.
