These findings underscore the need for more comprehensive security measures to protect data and reduce network exposure to such risksCisco Visual Networking IndexNew Zealand\u2019s IP traffic \u2013 comprising internet and managed networks such as video on demand services - is forecast to double by 2020, according to Cisco\u2019s Visual Networking Index.Glen Bearman of Cisco at a CIO roundtable discussion on collaborationThe CIO role is as critical as it ever was in terms of \u2018keeping the lights on\u2019 and being a strategic advisorCisco says this is the equivalent of all movies ever made crossing New Zealand\u2019s IP networks every 25 hours. In 2020, the country\u2019s Internet traffic will reach the equivalent of more than 72,000 DVDs per hour.The report likewise predicts the number of Kiwis online to grow from 3.9 million in 2015 to 4.4 million by 2020, an impressive 94 per cent of the population, it says. Globally, only 52 per cent of the population will be internet users by 2020.No captionCisco, however, says the dual trends of digital transformationand Internet of Things will have an even greater impact on traffic growth.By 2020, it says New Zealand\u2019s IP networks will support 17 million more devices and connections, up from 20 million in 2015 to 37 million by 2020.Applications such as video surveillance, smart meters, digital health monitors and a host of other machine-to-machine services are creating new network requirements and driving traffic increases. By 2020, machine-to-machine connections will account for 70 per cent of New Zealand\u2019s total IP connections and there will be 7.7 devices \/connections per capita, according to the report.No captionFaster broadband speeds are also driving growth in IP traffic, with the Government-sponsored Ultra-Fast Broadband rollout playing a leading role.New Zealand\u2019s average fixed broadband speed in 2015 was 19.5 megabits per second (Mbps), says Cisco. However, this will jump 2.5 times by 2020 to reach 49.1 Mbps.These speeds will see New Zealand jump ahead of the global average of 47.7 megabits per second in 2020, and rank near the fastest speeds globally, which will average around 51 Mbps across North America, Western Europe and Asia-Pacific.With the growing dependence on mobile and fixed broadband networks, security concerns are increasingly becoming top of mind for service providers, governments, businesses and consumers, says Cisco. DDoS damages Cisco says it worked with Arbor Networks to help quantify the current and future threats of DDoS (Distributed Denial of Service) attacks.No captionDDoS incidents can paralyse networks by flooding servers and network devices with traffic from multiple IP sources. The new DDoS analysis suggests that these types of breaches can represent up to 10 per cent of a country\u2019s total Internet traffic while they are occurring. No captionOver the next five years, Cisco says DDoS attacks are projected to increase from 6.6 million to 17 million attacks globally. No caption\u201cThese initial findings underscore the need for more comprehensive security measures to protect data and reduce network exposure to such risks.\u201dGlen Bearman, head of digital transformation, Cisco New Zealand, says a key consideration for businesses today is having the right role to lead digital in the organisation. He asks, \u201cShould it be the CIO or CDO (chief digital officer)?\u201d\u201cThe CIO role is as critical as it ever was in terms of \u2018keeping the lights on\u2019 and being a strategic advisor,\u201d he says, in a statement. \u201cBut with digital, it may not be necessary to create a new CDO role. Instead, it could be consumed \u2018as a service\u2019 just like many other areas of IT.\u201dHe says digital likewise needs strong leadership from the top. \u201cExecutive sponsorship of a digital transformation programme is critical,\u201d he says. \u201cThe executive must set a clear plan, and lead by example - and that means using new digital tools and processes to give others confidence that innovation really does work.\u201dThe State of Global Information Security 2016: The convergence of digital and cybersecurityNo captionNo captionSend news tips and comments to firstname.lastname@example.orgFollow Divina Paredes on Twitter: @divinapFollow CIO New Zealand on Twitter:@cio_nzSign up for CIO newsletters for regular updates on CIO news, views and events.Join us on Facebook.
