According to a new report by her Nokia, The Internet of Things (IoT) device infections have increased significantly in the last year.
Nokia claims that infection rates depend to a large extent on visibility of devices in Internet.
"In networks where devices are usually assigned to public IP addresses, we find a high rate of IoT infection. In networks where CGNAT (carrier grade NAT) is used, the infection rate is significantly reduced because the vulnerable Appliances are not visible in the network scan", The report said.
"With the advent of 5G, not only will the number of IoT devices increase dramatically, but also the percentage of those devices that will be accessible directly from the Internet".
Nokia has warned that other aspects of 5G will come to the surface new challenges related to safety of telecommunications: namely Network Function Virtualization (NFV) and Software-defined Networking (SDN). These data may pose risks to CSPs.
"CSPs network infrastructure is becoming more accessible to intruders, so they are increasingly targeted by skilled cybercriminals".
Η safety should be a priority and this means that it is necessary to integrate into networks from the beginning, covering all parts of the ecosystem, but managed by a central control point. In addition, according to Nokia, automated organization and management as well as prudential controls security are basic data.
