38 National Security Strategy and Strategic Defence and Security Review intervene with people who are at risk of radicalisation and to stop them before they begin to engage in any terrorist-related activity. Pursuing the terrorists 4.88 We will continue to take action to investigate, disrupt and wherever possible convict terrorists. We will continue to give law enforcement, security and intelligence agencies and our Armed Forces the capabilities to deal with attack planning in the UK and overseas, and in particular the means to deal with terrorists’ growing use of encrypted online communications and digital media. 4.89 We will increase the resources for counter-terrorism police and the security and intelligence agencies to pursue terrorists. In the police, we will provide more investigators, more police based overseas, and capabilities to investigate terrorist activity online and to process large amounts of digital media quickly and effectively. In the security and intelligence agencies, we will establish a new counter-terrorism operation centre with increased numbers of analysts and investigators, increase our global counter-terrorism reach, and upgrade our counter-terrorism technology, including technical intelligence collection and digital forensic capability. 4.90 The ability to acquire intelligence and evidence from electronic communications, subject to strict safeguards, is and will remain vital to the effective work of law enforcement and the security and intelligence agencies. In 2016, we will legislate to consolidate the investigatory powers that the public authorities require, with robust oversight, transparency and safeguards, and to ensure that the law keeps pace as communications technology advances. This legislation will build on the recommendations of three independent reviews published in the past year. It will update powers on the interception of communications, communications data and equipment, and will create the right to appeal to a higher court in the UK against decisions made by the Investigatory Powers Tribunal. It will overhaul and strengthen the existing scrutiny and oversight regime by establishing a new Investigatory Powers Commissioner, and give the public clarity about how the Government’s investigatory powers and capabilities are used. Through legislation such as the Justice and Security Act 2013, we have a robust legal and policy framework ensuring that the authorities’ actions are effective, necessary and proportionate. We will continue to maximise security, while implementing strict safeguards to ensure that privacy is protected. 4.91 We will ensure that terrorists who are convicted in the UK are then effectively monitored and managed in prisons. We will make further resources available to the police and to the National Offender Management Service for this purpose. 4.92 Terrorism thrives in unstable states and amid civil wars. We need to be able to find and track terrorists in these hostile environments. Where they pose an imminent threat to the UK, British interests abroad or to our allies, and there is no way to bring them to justice, we will act decisively. We will provide significant new investment to enhance our Special Forces’ Intelligence, Surveillance and Reconnaissance and global strike capability. Protecting ourselves from attacks 4.93 We will continue to invest in capabilities to protect ourselves against terrorist attack. We will invest in the protection of our transport systems, notably aviation, our borders, our CNI, and crowded places. We will continue to invest in systems which give us data in advance about people intending to come to this country, so that they can be checked against our records.
