Gartner predicts 40% of large organisations will have formal plans to respond to large scale business disruption attacks

More large enterprises to adopt formal cyber attack response plans
Large scale cyber attacks such as the attack on Sony Pictures have highlighted the degree of business disruption which can be caused.

In light of recent high profile cyber attacks, Gartner expects the proportion of large enterprises with formal plans to address business disruption attacks to rise from zero percent today, to reach 40% by 2018.

The analyst company said that the magnitude of aggressive attacks can cause prolonged business disruption, meaning that CISOs and business continuity managers need to increase ther focus on such attacks and adopt an approach that is oriented to detecting and responding to attacks.

"Gartner defines aggressive business disruption attacks as targeted attacks that reach deeply into internal digital business operations with the express purpose of widespread business damage," said Paul Proctor, vice president and distinguished analyst at Gartner. "Servers may be taken down completely, data may be wiped and digital intellectual property may be released on the Internet by attackers. Victim organisations could be hounded by media inquiries for response and status, and government reaction and statements may increase the visibility and chaos of the attack. Employees may not be able to fully function normally in the workplace for months. These attacks may expose embarrassing internal data via social media channels - and could have a longer media cycle than a breach of credit card or personal data.

"Entirely avoiding a compromise in a large complex enterprise is just not possible, so a new emphasis toward detect and respond approaches has been building for several years, as attack patterns and overwhelming evidence support that a compromise will occur," said Proctor. "Preventive controls, such as firewalls, antivirus and vulnerability management, should not be the only focus of a mature security program. Balancing investment in detection and response capabilities acknowledges this new reality."

Proctor pointed out that the risk to digital businesses is intensified, due to the high reliance of digital business processes on technology.

Gartner said that digital business should not be restricted by these revelations, but emphasis must be placed on addressing technology dependencies and the impact of technology failure on business process and outcomes. Information owners should be made explicitly accountable for protecting their information resources, ensuring they will give due consideration to risks when they commission or develop new digital business solutions.

The expectation that digital business will be a successful consumer business model relies on IoT devices being "always available." An interruption at any point during the end-to-end transaction process means that business transactions may not be completed, thereby negatively affecting customer allegiance and the revenue stream expected from the digital business offering.

As a result, the standard of due care for security program maturity will increase, with risk, security and BCM leaders getting more pressure and more support from executive boards than ever before. Executive boards have increased their attention on cybersecurity since 2012, but new revelations of business disruption attacks provide a fresh opportunity to build the new business case for cybersecurity investment and institutionalize more-proactive thinking about cybersecurity risks.

"CISOs and chief risk officers (CROs) can and should persuade executives to shift their thinking from traditional approaches toward risk, security and business continuity management. Security is not a technical problem, handled by technical people, buried somewhere in the IT department," said Proctor. "Organisations need to start solving tomorrow's problems now."
