Should ISPs Cut Off Bot-infected Users?
richi writes "There's no doubt that botnets are a major threat to the safety and stability of the internet — not to mention the cleanliness of your inbox. After years of failure to act, could we finally be seeing ISPs waking up to their responsibilities? While ISPs can't prevent users getting infected with bots, they are in a superb position to detect the signs of infection. Contractually, the ISP would be reasonably justified in cutting off a user from the internet, as bot infection would be contrary to the terms of the ISP's acceptable-use policy."
Should ISPs Cut Off Bot-infected Users?
Yes. Some ISPs already cut off P2P users. By comparison botnets are a real threat.
Trolling is a art,
Yes, yes! A million times YES!
A doctor would quarantine a contagious patient. An ISP should quarantinean infected PC.
If I were God, wouldn't I protect my churches from acts of me?
>"Should ISPs Cut Off Bot-infected Users?"
After a suitable warning to the customer/administrator, yes. Absolutely. But it should be made very easy for the customer/administrator to reactivate their service, too.
Sure it's fair.
Once you're infected the rest of the Internet with crap, you're costing them more money in tech support calls from people complaining about you. Why would they pay to keep launching your crap packets into the core? Be your own ISP if that's your agenda. If you take care of your network, you won't run into this.

Because you've apparently never been blacklisted because one of your members sent comcast.net 250,000 spam emails in a 24-hour period. Because you've never had your SMTP server so overloaded with botnetted messages that delays of up to an hour were occurring for legit traffic. Because you've never had to block port 25 for out-of-area SMTP traffic because of complaints from other local partner ISPs. Yes, we disable access for identified botnet members and spammers. The infections of a handful of our members' PCs aren't going to ruin the experience for our other 6500 members.
ISPs should be responsible for filtering out bot activity, but it's not really fair to anyone to cut them off entirely. After all, it's not entirely their fault they got infected... hell even if they're responsible with updates and activity they could have been compromised by some new vulnerability.
Has firewall technology not been able to keep up with bulk ISP traffic or something?
I understand that users ought to control their own home firewall, but ISPs should have firewalls / filters they control further upstream, where they can add rules to block certain types of traffic only when necessary. But I guess if they have it, then that means they're kinda liable for configuring it effectively and can thus be held responsible for attack traffic that does get through.
Anyway, I don't like the idea of being cut off from network access without at least a few weeks' advance notice and time to respond. Which is virtually an eternity in botnet time... which makes that whole approach somewhat pointless.
They could just redirect them to a portal, where they get informed that their computer is sending out viruses.
The portal would offer a free virus scanner and the option to have several ports closed by the ISP (checked by default) ;)
- ports that could later be reopened by going to the "experts"-page
If the user insists, they of course can go on and use the internet anyway. But only after clicking "ok" to a sentence declaring that they are now informed and
"solely liable to any damage they might do to the internet"
ISPs should hand out routers which utilize Network Access Protection by default.
The router should verify if the endpoint is clear for internet access, and if it's not, it should limit user access to antivirus vendors, known OS upgrade services etc and requesting user to follow this link to repair their computer(or have it cleaned by someone skilled enough).
There are (or should be!) multi-platform NAP/NAC solutions to do this.
Of course, users should have opt-out option, which allows them to disable the NAP, and take responsibility of maintaining their systems themselves without "middle-maintenance".
Opted out systems would receive direct disconnect until user verifies by phone to the operator that their misbehaving system has been fixed. (for example, spam zombie)
There are no atheists when recovering from tape backup.
No. You have a DOCTOR cut it out. The question here is whether or not most ISP's are competent in determining what really is bot activity. A bunch of false positives will be miserable -- as will having to prove to some first-tier customer support person that your system is not infected (as in never was) or that it is actually cleaned and should be allowed back online.
And pity the person that has their ISP connection blocked that uses voice over IP to call customer support. If the ISP blocks the MODEM life is going to be interesting.
Oh, and you won't need to look up that phone number, will you?
Overall, getting infected systems of the net is a wonderful idea, but one that could be a complete mess if done poorly.
Life is short: void the warranty.
They're Internet SERVICE Providers. Not Internet Police, nor Internet Guardians. They exist to provide people with access to the Internet for a fee. Now a lot of ISPs already do plenty that is contrary to the best Interests of the customers. Bad behaviour ranges from price gouging and using misleading advertising, to draconian terms of service (usually because they're able to due to a monopoly or collusion), to playing fast and loose with customer's private data (often in the name of anti-piracy). Do you really want to give these same ISPs the power to take a customer's money and provide them with nothing based on nothing other than their own conclusion that a customer is infected? That's madness. An ISP should be providing a customer with help to remove the infection, not removing their access to the Internet.

So on one hand, ISPs should not regulate the type of traffic and should not sniff, etc...
On the other hand, ISPs should cut off virus-infected computers. Apparently, they ARE sniffing or monitoring in some way in order to cut you off.
Just wait for a company to decide that being a torrent feeder is being part of a botnet and thus torrent feeders must be cut off. Good luck getting back on again.
If it is really botnet activity, why not just block the botnet activity but not the non-botnet activity? If you can't determine if it's botnet activity well enough, then how are you going to choose who gets cut off?
(I am not necessarily decidedly against this, but at the moment, it seems to be somewhat hypocritical to be against ISP filtering and for ISP cutting off [on their own]. Enlighten me. :) )
What is it about spam and malware that causes people to completely lose their minds? What are you worried about botnets anyway? Either your system is secure and it won't be a problem for you, or your system is not secure and you are, by your own admission, "part of the problem." This isn't like quarantining carriers of a deadly disease. It's not exactly difficult to secure your own system against the nasties on the internet. But people are here supporting the idea of severing a person's internet connectivity because they've been a victim of some asshole on the internet. I think we can all agree that the internet is culturally revolutionizing, and has already proven itself to be an extremely important tool in the promulgation of free speech. But once you throw this crap in the mix we have people asserting these authoritarian opinions which, quite honestly, scare the shit out of me.
At the very least, if there is some set of criteria for disconnecting somebody from the internet, there must also be criteria for how to get reconnected and a very clear and doable set of instructions how to get back online. Otherwise you will end up permanently silencing people.
This has happened to me once. I got a virus and a couple hours later, my internet was off. I called the service desk and I was told that my computer was infected and get this, I need to download a patch to fix it. "How do I download a patch when my internet is off, I asked." "Bring your computer to the service center when we open on Monday." I instantly canceled my service. I was a college student at that time. Some tasks required the internet. In fact the only way to turn in my physics homework was to upload it to the server by 2am on Tuesdays and Thursdays. I don't need to be worrying about my internet shutting off at random times and having to make a midnight dash to campus to use the library computer.
I try to keep my computer clean. I run firewalls and I have virus scanners, but if you haven't been infected with a virus before then you haven't been on the internet long enough. Sooner or later you'll get infected and god forbid if you rely on the internet. IE VoIP or server hosting. Why do I get punished for what other people do? Should car manufacturers be able to remotely turn off your car when your car starts to leak oil or freon?
Wait, your big plan is to:
1. Cut off their access (presumably also to e-mail)
2. Send them an e-mail that they must reply to if they want to be able to read email.
And where exactly are they supposed to read this email?
Exactly. Whats from stopping an ISP from simply cutting you off because you were using too much bandwidth, stating that you are infected?
Nothing. Just like nothing is stopping them from doing it now.
The first time, we take the member's word that they've cleaned or replaced the computer. After that, if it recurs, we need to see either an invoice from a repair shop or retail shop for repair of purchase of a computer. We provide CDs here in our office with removal tools, and we do provide removal and cleanup services.
We also provide download links for security software right from our tech support portal, and a complimentary CD with the same software with every new subscriber. 3 times a year we offer a class on intro to pc and internet security. If someone's still getting infected after all the resources we've made available, then tough love may be just what's needed.
Being able to connect to any port and to receive connections on any port is the definition of Internet access. I absolutely should be able to run a mail server on my home machine.
Now, if the ISP were to block incoming port 25 by default, and people who wanted it could fill out a quick form or something, maybe that would be okay.
When the latest Ubuntu ships I often leave my torrent client seeding for a couple weeks.
This is a great thing! Within 3 days of this becoming standard practice, there won't be any windows users with an internet connection!
"People don't want to learn linux" hasn't been a valid excuse since '03.
