GCHQ Planning UK-Wide DNS Firewall (thestack.com) 194

Posted by msmash from the big-brother-and-his-van dept.
An anonymous reader writes: UK surveillance agency GCHQ is exploring the use of a national 'firewall' in its fight against cybercrime, according to the organisation's head of cybersecurity. Alongside BT, Talk Talk and Virgin Media, GCHQ will work to filter out websites and email campaigns which are known to contain malicious content. The intelligence organisation believes that the best to way to set up such a blockade would be to build a national domain name system (DNS). In a speech delivered at the Billington Cyber Security Summit in Washington DC, director general for cyber security at GCHQ, Ciaran Martin, said: 'We're exploring a flagship project on scaling up DNS filtering: what better way of providing automated defences at scale than by the major private providers effectively blocking their customers from coming into contact with known malware and bad addresses?'

      Not much good in this at all. There are already alternative DNS providers that will block most of this stuff selectively by each user. I use OpenDNS myself for this purpose. This is effectively censoring by the government, and nothing less.

      Yes, it will eventually used to block torrent sites, the Pirate Bay, etc. It will be used to block any of the other downloading sites that are available whether they are torrent trackers or straight downloads or streaming sites.

      Even more, if riots break out, or dissension protests start up, all of a sudden Twitter and FB will be temporarily blocked to prevent coordination by participants. The US has already done similar to this, for instance in bay area BART stations where they shutdown the cell phone repeaters to prevent communication in the stations when Oakland had riots/protests going on. If UK can do it by simply blocking DNS to these sites, the same results will happen.

      Who decides what is considered "MalWare"? What are the criteria? Malware could be the typical kind, but could also include hacking software, keygen apps, apps that the RIAA/MPAA and big-media doesn't like? Everyones idea of what is malware, is probably slightly different. Viruses yes, but not all the others are malware. I know most virus scanners pick up keygen's and other cracking software as a virus even if it's not, but because want to scare away people from using them.

      • OpenDNS is owned by Cisco, talk about having your tongue up the ass of the kind of corporate fascist scum who have governments in their pocket.....

If you don't like OpenDNS, then pick another provider, or run your own DNS server.

    • Well, with name based virtual hosts you certainly need some sort of name to send the request to, whether provided by DNS or /etc/hosts or whatever.

This file is traditionally editable only by root, and root access is often impractical to gain on any type of device other than a desktop or traditional laptop PC, especially a smartphone or a tablet computer running a smartphone operating system.

When the government realizes that people are circumventing their firewall then I'd fully expect them to do what they can to block that traffic as well.

    What better way of allowing the UK government to censor what British people can see and hear on the Internet, without the huge majority of them having any idea that their Internet access is being censored?

    And for those who have suggested this is no big deal, just wait. This is a case of "First they came for the communists", with a vengeance. Quite apart from the fact that this is exactly what the Chinese government has been doing with its "Great Firewall of China" - and getting it in the neck for alleged tyranny, totalitarianism and censorship.

    Of course, how this policy would work out in practice does depend very much on who decides what constitutes "known malware and bad addresses [sic]". Previous draconian laws passed by the British Parliament were, we were solemnly promised, to be used only in the most serious of terrorist cases. A couple of years later, the powers were in fact being used by town councils to spy on what people put into their rubbish, how they kept their gardens, and other such personal and utterly non-vital matters.

    If a law is passed establishing a "Great Firewall of Britain", we can be quite sure that within a couple of years literally thousands of government employees - from the Prime Minister to town hall clerks - will be contributing "bad addresses" to the cumulative DNS blacklist. Just like the current Homeland Security watch lists in the USA, thousands of items will be added every month, and nothing will ever be removed.
