Changes in computing fabric, devices and services formed by digital business continue to shape risk and security landscapes.
According to Gartner, by year-end 2017, more than 20 percent of enterprises will have digital risk services devoted to protecting business initiatives using devices and services in the Internet of Things (IoT).
“Business imperatives have driven the convergence of the Internet of people, computers and things, transforming most enterprises into digital businesses and reshaping cybersecurity,” says Christian Byrnes, managing vice president, Gartner.
“An inflection point in business and technological innovation has occurred, which we refer to as the 'digital explosion' and the 'race to the edge.”
Byrnes say the traditional model ascribed for decades to IT security has been one of confidentiality, integrity and availability (CIA) - most organisations in 2015 have not shown a consistent ability to substantially mitigate those risks.
The CIA model is still relevant and applicable in cybersecurity, but it isn't enough.
“The race to the edge has pushed the environment for protecting data and infrastructure into the physical world, merging functions focused on data and information with functions that make actual changes to people and their surrounding environments,” Byrnes adds.
“Protecting information alone isn't enough, and ensuring the confidentiality, integrity and availability of that information isn't enough.
“Leaders in risk and cybersecurity must now assume the responsibility of providing safety for both people and their environments.”
For Byrnes, the digital explosion is moving technologies from core architectures to a highly distributed and fit-for-purpose edge.
As explained by Byrnes, “Core" describes general-purpose technologies and services for computing, such as servers, laptops and mobile platforms, as well as cloud and mobile services.
"Edge" is a term used to describe devices that aren't servers or laptops and perform specific functions in the business and are positioned at the boundary between the business and its customers, partners and providers.
Byrnes says the core and the edge are mixtures of traditional IT, as well as IT and components of the IoT.
The digital explosion disrupts the foundations of services for technology and information and elevates traditional IT services, such as cloud computing and advanced analytics, to a mandatory status to support the scale and functional needs of the edge.
The edge itself is more physical than digital, with devices and physical assets becoming more intelligent to meet the shifting demands of business - this is the core-to-edge continuum.
Byrnes believes the other continuum in the cybersecurity scenario is one of openness.
An organisation must decide, as part of its evolution in digital business, on the ultimate transparency of its services to its customers.
“The degree of openness depends on an organisation's approach to data accessibility, infrastructure used, culture, process and adaptation to change,” Byrnes adds.
Gartner believes that the demands for transparency in the digital business of 2020 will drive more organisations toward openness as a strategy of priorities.
Requirements for large-scale, real-time adaptive protection, safety and privacy at the digital and physical levels will drive new cybersecurity skills, practices and technologies.
Byrnes believes the race to the edge requires that organisations consolidate the prioritisation of cybersecurity efforts across broader technology areas that require protection and are interdependent.

In addition to a more comprehensive approach to digital risk, organisations must prepare for new cybersecurity skill sets in areas such as vendor portfolio management, safety engineering, machine-to-machine (M2M) communications, embedded software, and systems security and cyber-physical systems.
“Cybersecurity professionals are the new guardians of big changes in the organisation,” Byrnes adds.
“Such professionals must practice business resiliency and adaptability, because they are now so integrated with digital business decisions that leaders cannot tell where business ends and cybersecurity begins.
“The digital explosion and the race to the edge have achieved what previous waves of technology evolution have failed to do - to integrate cybersecurity professionals and business leaders into effective teams for the protection and safety of the organisation.”
