Spy chiefs size up net snoop gear

The security minister has confirmed officials are considering installing technology that could enable on-demand wiretapping of all communications passing over the internet by the intelligence services and law enforcement.

Lord West told Parliament on Monday that civil servants working on the Interception Modernisation Programme (IMP) were considering how Deep Packet Inspection (DPI) equipment "might support the lawful interception of communications and separately the lawful acquisition of communications data".

It's the first time the government has publicly acknowledged its interest in DPI equipment. A delayed Home Office consultation on IMP is due to be launched "shortly", West said.

The Programme as envisaged by GCHQ and MI6, according to sources, has two aims.

First, spy chiefs want to create a massive central repository of communications traffic data. Such data contains the powerful details of who contacts whom, how, when and where. Most major ISPs and telecoms firms already retain much of this data, but some do not, and many email, VoIP, instant messenging and social networking services retain little.

This in turn would facilitate the second aim of the system, the interception of the content of internet communications. As now, this would require a warrant under the Regulation of Investigatory Powers Act (RIPA), but each wiretap would be much easier to implement.

West's comments confirm our sources' information that officials are considering a network of DPI probes inside the UK internet and telecoms infrastructure that could fulfil each ambition. The equipment can monitor everything in each data packet passing its location in the network, allowing both "the lawful acquisition of communications data" and the "the lawful interception of communications".
