CA Warns Of Massive Botnet Attack
m4dm4n wrote to mention a story running on The Register which describes a coordinated malware attack designed to establish a massive botnet. From the article: "The attack involves three different Trojans - Glieder, Fantibag and Mitglieder - in a co-ordinated assault designed to establish a huge botnet under the control of hackers. Computer Associates reckons that access to the compromised PCs is for sale on a black market, at prices as low as five cents per PC."
I would suggest using user levels.
regular customers would get level 1 or level 0. (Web and mail access, no incoming ports, etc.)
Then it would be a customer's decision to apply for a higher level. maybe pass a test, portscan, etc. sign something that gives them responsability for the services running on their box.
They could even make higher levels cheaper, as an incentive for customers to educate themselves. like level 4's get 15% off their monthly bill.
