The fifth generation (5G) mobile network offers many advantages in \nterms of speed. It allows faster, smoother downloads of video and other \ncontent. <\/p>\n\n\n\n
5G has the potential to change the way we use mobile data in both our\n business and personal lives so what implications does it have for \nonline security? <\/p>\n\n\n\n
The risk from 5G use is unlikely to come from the technology itself. \n5G uses encryption and improved verification methods so it is \nsignificantly better than the earlier 3G and 4G standards. However, this\n does not mean it is protected from all threats.
In practice, \nthe biggest issue is likely to come from the Internet of Things (IoT). \n5G makes new data connections possible so there will be new ways to \nexploit devices. A whole range of IoT devices including security \ncameras, smart speakers, fridges, baby monitors, medical devices and \nlots more are now connected to the internet and this presents online \nsecurity risks.<\/p>\n\n\n\n
There will be as many as 25 billion IoT devices by 2021. These are \nlikely to attract hackers according to Gartner research. The problem is,\n low-cost IoT devices don\u2019t have the processing power to support the \nsophisticated security that computers and smartphones enjoy.<\/p>\n\n\n\n
Using 5G speed, hackers can rapidly scan devices for vulnerabilities like default passwords. Once a connected device is exploited, criminals can extract and transfer data quickly, before the attack is even discovered. <\/p>\n\n\n\n
Direct connections to mobile internet makes cyber attacks easier as \nthere\u2019s no added security of domestic routers and firewalls. It can also\n be an issue for businesses if employees use 5G instead of the secure \nnetwork to access corporate data.<\/p>\n\n\n\n
While most 5G attacks are likely to have evolved from existing threats, it opens up some new avenues too. New technology incorporating artificial intelligence and so-called \u2018deep fakes\u2019 could lead to the creation of robot calls that imitate trusted friends or businesses.
As 5G becomes a key part of many countries\u2019 communication infrastructure, it will likely become a tempting target for nation-state attackers too. These attacks will seek to disrupt communications and other activity.
As with any technology, basic errors such as misconfiguration can leave online security vulnerable. In an effort to prevent problems, communications providers and governments are scrambling to introduce security standards for 5G. It\u2019s important the risks are understood and corrected before they become a major threat.<\/p>\n","protected":false},"excerpt":{"rendered":"
