"Protector on-line" - free for volunteer testers.

This is the soon-to-be-launched service that allows you to take advantage of "protector's" features (see the desciption later on this page) without the need of installing it on a server of your own. For a small consideration you will be able to have your e-mails filtered by the "protector" software running on our servers - simply by changing the POP server you connect to. Most people wont even have to change their e-mail address.

I will shortly be starting beta-test trials of this version of the software and am looking for a number of interested volunteers to subscribe to the service free of charge for a few months, If you are interested in joining the growing army of beta-testers of this service, then send an e-mail to chris@lowth.com. Please note that I am allocating a limited number of free subscriptions on a first-come-first-served basis.

Would you like to help?
I have been developing 'protector' as a hobby (with contributions from others) over a period of three or four years. The level of interest in the software has escalated far beyond my original expectations, and it is currently being installed in about 130 sites per month (and growing). I am now looking for opportunities to take it further - to provide support for a wider range of operating systems and file formats, and develop it into a "carrier grade" service. In order to achieve this objective I am actively seeking assistance - in terms of financial sponsorship and development effort. If you would like to help with the development or funding of the project, please e-mail the project at protector@lowth.com - thanks.

Overview

Protector is a free, open source (GPL), low maintenance e-mail virus blockade system, used mainly to protect MicroSoft windows e-mail client systems from attack, but useful for other client types as well.

Protector lives on e-mail servers that handle in-bound messages. It checks incoming e-mail for attachments that could contain viruses, worms etc - and replaces the offending attachments with standard warning messages (or modifies them to remove the dangerous parts) before passing them on to their intended recipients. The original "dangerous" attachment is saved in a directory that only the system administrator can access.

Protector is NOT a virus scanner in the traditional sense: It does NOT scan attachments for virus signatures, but blocks or edits attachments that could contain viruses. So *.exe, *.vba etc attachments don't get through. This means that you don't have to keep protector up to date to stay protected against the growing tide of new viruses and worms.

Protector does not work by blocking listed types, but by blocking ALL BUT a listed set of types.

The logic employed by protector to determine the file types contained in attachments is based on a modified version of the "file" command, and a number of type-specific validation programs - it does not rely on the actual name of the file, or the "content-type" declared in the attachment header. It also looks inside ZIP, TAR and other archive formats, and checks the files contained in them.

Some types of files are allowed through only under certain conditions. The main example being that MS Word documents are blocked if they contain ANY macros, but allowed through otherwise.

Protector grew out of a need to protect a small network that I manage in my spare time from the dangers of e-mail borne viruses and trojans. A number of installations exist round the world and feed back from users has allowed me to improve the system - in terms of reliability, performance, ease of use and the breadth of file types "allowed through". Development is still underway, and a new release will be available shortly that allows a far larger set of file types through, allows scripts to be removed from attachments (eg: JavaScript can be removed from HTML files), and is significantly easier to tailor.

Constructive critisism is warmly invited
