Cyber attack a nuclear threat

The risk of a serious cyber attack on civil nuclear power plants is increasing, according to a study from policy institute Chatham House.
The report, Cyber security at civil nuclear facilities: understanding the risks, says the growing reliance on digital systems and use of commercial "on-the-shelf" software leave nuclear power plants increasingly vulnerable.
The study, which examined the range of potential cyber threats to nuclear installations, also found a lack of awareness of risks among senior executives. It warns that the industry is mistaken in believing nuclear facilities are protected from cyber attack because they are "air gapped" - isolated from the public internet.
"Not only can air gaps be breached with nothing more than a flash drive, but the commercial benefits of internet connectivity mean that nuclear facilities may now have virtual private networks and other connections installed, sometimes undocumented or forgotten by contractors and other legitimate third-party operators," says the report.
Most nuclear workers also lack training in spotting and combating potential attacks which, combined with communication breakdowns between engineers and security personnel, leaves staff with little understanding of key cyber security procedures, the study found.
Recommendations to boost security at civil nuclear sites include developing guidelines to measure cyber risk in the industry, such as through an integrated risk assessment that takes into account security and safety measures, and promoting good IT hygiene, such as forbidding the use of personal devices.
None of England’s water and sewerage companies achieved all environmental expectations for the period 2015 to 2020, the Environment Agency has revealed. These targets included the reduction of total pollution incidents by at least one-third compared with 2012, and for incident self-reporting to be at least 75%.
The UK’s pipeline for renewable energy projects could mitigate 90% of job losses caused by COVID-19 and help deliver the government’s ‘levelling up’ agenda. That is according to a recent report from consultancy EY-Parthenon, which outlines how the UK’s £108bn “visible pipeline” of investible renewable energy projects could create 625,000 jobs.
Billions of people worldwide have been unable to access safe drinking water and sanitation in their homes during the COVID-19 pandemic, according to a progress report from the World Health Organisation focusing on the UN’s sixth Sustainable Development Goal (SDG 6) – to “ensure availability and sustainable management of water and sanitation for all by 2030”.
The UK government is not on track to deliver on its promise to improve the environment within a generation and is failing to stem the tide of biodiversity loss, a damning new report from MPs has revealed.
The UK's solar energy capacity must treble over the next decade for the country to achieve net-zero emissions by 2050, but is only set to double under a business-as-usual scenario.
The Taskforce on Nature-related Financial Disclosures (TNFD) has today been launched to support financial institutions and corporates in assessing and managing emerging risks and opportunities as the world looks to reverse biodiversity loss.
