IT disaster recovery, cloud computing and information security news

More than half (54 percent) of cyber security professionals have expressed concerns that quantum computing will outpace the development of security technologies, according to new research from the Neustar International Security Council (NISC). Keeping a watchful eye on developments, 74 percent of organizations said that they are paying close attention to the technology’s evolution, with 21 percent already experimenting with their own quantum computing strategies.

A further 35 percent of experts claimed to be in the process of developing a quantum strategy, while just 16 percent said they were not yet thinking about it. This shift in focus comes as the vast majority (73 percent) of cyber security professionals expect advances in quantum computing to overcome legacy technologies, such as encryption, within the next five years. Almost all respondents (93 percent) believe the next-generation computers will overwhelm existing security technology, with just 7 percent under the impression that true ‘quantum supremacy’ will never happen.

Despite expressing concerns that other technologies will be overshadowed, an overwhelming number (87 percent) of CISOs, CSOs, CTOs and security directors are excited about the potential positive impact of quantum computing. The remaining 13 percent were more cautious and under the impression that the technology would create more harm than good.

“At the moment, we rely on encryption, which is possible to crack in theory, but impossible to crack in practice, precisely because it would take so long to do so, over timescales of trillions or even quadrillions of years,” said Rodney Joffe, Chairman of NISC and Security CTO at Neustar. “Without the protective shield of encryption, a quantum computer in the hands of a malicious actor could launch a cyber attack unlike anything we’ve ever seen.”

“For both today’s major attacks, and also the small-scale, targeted threats that we are seeing more frequently, it is vital that IT professionals begin responding to quantum immediately. The security community has already launched a research effort into quantum-proof cryptography, but information professionals at every organization holding sensitive data should have quantum on their radar. Quantum computing's ability to solve our great scientific and technological challenges will also be its ability to disrupt everything we know about computer security. Ultimately, IT experts of every stripe will need to work to rebuild the algorithms, strategies, and systems that form our approach to cyber security,” added Joffe.
