industry news Environmental control to play key role in the data centre of the future Fresh forecasts from Occams Business Research & Consulting (OBRC) predict that the global data centre cooling market will grow at a compound annual growth rate (CAGR) of 14.95% between 2016 and 2023. Greg McCulloch, CEO of Aegis Data, gives examples of technologies that will ultimately depend on a data centre’s cooling capabilities, “AI, IoT, VR and AR – what all these technologies have in common is that they are predicted to grow in prominence over the next few years, and that they have complex and demanding data requirements.” In order to thrive in this age of exponentially growing data volumes, organisations are increasingly turning to high performance computing (HPC) services. In relation to cooling, for a data centre to comfortably accommodate HPC it must be able to accommodate its superior processing power, which often involves concentrating more computing power in higher density racks. This produces far more heat than the standard data centre configuration, meaning that efficiently cooling this space becomes far more important for supporting this technology. Huge data centre providers are going to great lengths to minimise their cooling costs. For example, Facebook located a data centre in near-arctic Luleå, northern Sweden. Greg commented, “You don’t need to have the vast resources of Facebook to access the kind of cooling efficiencies needed to support the ever- expanding data requirements of new technologies. There are various other approaches available, including liquid or conductive cooling.” For further information visit: www.aegisdata.net ‘Unintentional insiders’ could cause most damage to an organisation According to a new survey released by SANS Institute, organisations are so single-minded about defending against external attacks, that they are ignoring a threat with vastly greater potential for damage. 76% of security and IT professionals polled globally said the greatest potential for damage comes from a possible data breach involving employees or contractors trusted with insider access to sensitive data. 40% worry about insiders acting out of malice; 36% say the risk from insiders who are careless with security, or fooled by scams from outside, would do the greatest damage to reputations and bottom lines in the event of an attack. Only 23% predicted the most damage could be done by attackers from the outside. An unintentional insider is defined as a user who is tricked into or manipulated into causing harm, or whose credentials have been stolen in phishing or other user-focused exploits, 8 | October 2017 designed to let attackers pose as legitimate users to access privileged information. A malicious insider, on the other hand, is someone who knowingly causes harm and damage to an organisation by stealing, damaging or disclosing information. As organisations deploy the latest security tools and techniques to protect from ever creative and sophisticated outside attackers, cyber criminals are looking for easier targets. Users who already have access to an organisation’s most sensitive data, for example, and aren’t as hard to fool as security systems. While security professionals clearly understand the risks that insider threats pose, very few seem to have any idea how much damage could be involved. 45% of respondents said the cost of a potential loss was ‘unknown’, while 33% said they had no specific estimate of cost.
