Attack on critical infrastructure imminent
26 February 2019
More than half (59 per cent) of respondents to the latest social media poll conducted by information security event, Infosecurity Europe 2019, believe that an attack on the UK’s critical national infrastructure is likely this year.
More than half (59 per cent) of respondents to the latest social media poll conducted by Infosecurity Europe 2019 – Europe’s number one information security event – believe that an attack on the UK’s critical national infrastructure is likely this year.
As more devices, systems and infrastructure are connected to the internet, the cyber and physical worlds are becoming increasingly linked, opening up new attack vectors. According to Ciaran Martin, head of the UK's National Cyber Security Centre (NCSC), a major category one (C1) attack on our critical infrastructure – one that disrupts essential services, or affects national security –is a matter of “when, not if”.
The responses to Infosecurity Europe’s poll also indicate that organisations in all sectors are not properly prepared to manage security effectively across both cyber and physical environments. Lack of collaboration and low levels of awareness of key legislation are the biggest problems. The challenges and complexities posed by the convergence of cyber and physical security will form a key part of the conference programme at this year’s Infosecurity Europe 2019 event.
Over two thirds (68%) of respondents say the security teams in charge of their physical and cyber infrastructures never collaborate. This disconnect leads to misaligned plans and conflicting priorities, while creating ‘silos’ that make it difficult for CISOs to gain full visibility of controls and risks across both IT and OT (Operational Technology) environments.
“Defending critical assets is a team sport,” says Nigel Stanley, Chief Technology Officer and global head of OT cybersecurity at TÜV Rheinland. “IT, physical and OT teams need to get their act together and start to share and learn from each other.”
Kevin Fielder, Just Eat’s Chief Information Security Officer, agrees. “The increasing convergence of cyber and physical environments is inevitable, but managing them in a cohesive way will strengthen enterprise security.” According to Kevin, it’s the insider threat that needs most urgent attention. “Those intent on accessing money, information or IP will often find it easier to do so from the inside – and we’re moving to a world where this can mean immediate impact to life. Hacking a building’s management systems, for example, could suppress a fire alarm or sprinkler system, or prevent people leaving.”
Only 16 per cent of respondents to the Infosecurity Europe poll were aware of the EU’s NIS Directive –which is designed to improve the security and resilience of network and information systems – and its implications. The legislation, which was put in place in 2016, sets out security requirements that apply to all operators of essential services and digital service providers (DSPs). Failure to adhere to these could leave security gaps that present attackers with ‘open doors’ through which they can access infrastructure and physical assets. UK organisations found to be non-compliant can be fined up to £17 million.
“I can’t believe that any cyber security leader in a sector impacted by the NIS Directive would be unaware of its implications for their business,” says Nigel Stanley. “Lack of commitment to secure critical infrastructure is the worst sort of negligence. Forget what the regulators demand – organisations should take the initiative and secure assets based on a proportionate cyber security and business-led risk assessment.”
Kevin Fielder believes that if the industry doesn’t take the lead, further regulation will follow. “It really is in our best interest to self-regulate and protect the public. If the industry doesn't produce connected devices that are, by default, secure and manageable over the long term, it won't take many real incidents for government regulations to quickly materialise.”
