Im not saying this is a bad thing persay. It might not be for your corporate network, but it should be fine at home. Im not talking about the security of the application, im talking about the security of the BOINC servers. The same code is used on all of them, one worm could bring them all down, one bug, etc. etc. etc. I dont think the DOS vuln makes it insecure, im just wondering why they picked seti and not microsoft, or other sites, because they usually have a purpose. Yes, it is supposively more private and secure. They can also have you process a lot more data with the new client. , thats like saying linux is more secure, its very suggesttive, most viruses attack microsoft because most ppl use windows, if everybody used linux, it would be hell. Linux is open source like boinc and since you can mod the kernel, system hijacking would be a HUGE problem. The fact that its open source enables everybody and their mother to find holes. Im not saying linux is insecure, but it would be if we all ran it. In this way, boinc secuity may end up bieng a huge problem, however, i think boinc is a great idea, i wish dnet, fightaids, grid etc. would switch to it, DNET is hogging my processor,grrrr.... thanks for the response. Any other opinions?
