  1. Theworldof5thGenerationTelecomNetwork Whatis5G? 5G is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and4Gnetworks.5Genables anewkind of network that is designed to connect virtually everyoneand everything including machines,objects, and devices. 5Gwirelesstechnologyismeanttodeliverhighermulti-Gbpspeakdata speeds, ultra-low latency,morereliability, massive network capacity, increased availability, and a more uniform user experience to more users. Higher performance and improved efficiency empower new user experiencesand connect new industries. Howdoes5Gwork? Wirelessnetworksarecellsitesdividedintosectorsthatsenddatathroughradiowaves. Fourth-generation (4G) Long-Term Evolution (LTE) wireless technology provides the foundation for 5G. Unlike 4G, which requires large, high-power cell towers to radiate signals over longer distances,5Gwirelesssignals are transmitted through large numbers of small cell stations located in places like light poles or building roofs. The use of multiple small cells is necessary because the millimetre wave (mmWave) spectrum-- the band of spectrum between 30 and 300 gigahertz(GHz)that5Greliesontogeneratehighspeeds--canonlytravelovershort distances and is subject to interference from weather and physical obstacles, like buildings or trees. Previous generations of wireless technology have used lower-frequency bands of spectrum. To offset the challenges relating to distanceand interference with mmWave, the wireless industry is also considering the use of a lower-frequency spectrum for 5G networks so network operators could use the spectrum they already own to build out their new networks. Lower-frequency spectrumreaches greater distancesbut has lowerspeed and capacitythan mmWave. Howfastis5G? 5Gdownloadspeedscancurrentlyreachupwardsof1,000 megabits per second (Mbps) or even up to 2.1 Gbps. To visualize this, a user could start a YouTube video in 1080p quality on a 5G device without it buffering.

Defining5Gsecurity Today,theconceptof“5Gsecurity”lacksan official definition asthe technology is still fairly new andevolving. This is not to say that 5G security does not exist. Security was one of the primary considerations in5G's development and planning. When it comes to 5G security,we need to think about it as a balancing act. On one hand, security was built into 5G from the ground up. However, along with the increased bandwidth and speed, a tidal wave of new devices and connections will make managing security much more difficult.

  3. Atitscore,5Gwasbuilttoensurethereliabilityofconnections.AnEricssonwhitepaperlists five core properties of 5G security: resilience, communication security, identity management, privacy,andsecurityassurance.Accordingtothedocument,5G’s trustworthiness is made possiblebyasetofsecurityfeaturesthat were builtusing system designprinciples applied with arisk-based mindset. Delvingintothetechnicaldetailsofthe5G security architecture is beyond the scope of this article.Butifthereisoneelementthatstandsoutandshouldbehighlightedhere,itisthe conceptof network slicing. Network slicing allows different networks and services to share the same infrastructure but are isolatedandsegregated from each other. Network slicing carves out (or slices, as it were) specific types of network traffic to match various use cases — be it enterprise, consumer, IoT or publicsafety. 5G’s securityarchitectureallowsforsignificantperformancebenefitsanddiversityof applicationsas it leverages network slicing, cloud-based resources, virtualization, and other emergingtechnologies. With these additions and changes, however, new security risks and additional attack surfaces mustbe addressed. • 5GSecurityBenefits • Thetransitionto5GSecuritytechnology providesorganizations with plenty ofbenefits, yet itis necessaryto consider 5G cybersecurity impacts aswell: • Decreased Traffic Visibility:As 5G makes mobile networks more usable, employees and business devices may start to use them more. Unless an organization has a WAN solution like Secure Access Service Edge (SASE) in place, this could mean that these companieswould lose visibility into some business traffic. • Increased IoT Usage: IoT devices have historically had poor security, creating potential gapsinanorganisation’ssecurityandexpandingitsattacksurface.Withthegrowthof IoT usage due to the rise of 5G, organizations must deploy IoT security solutions to ensurethat their new devicesare appropriately protected.

  4. Supply Chain and Software Vulnerabilities: 5G supply chains are limited, and the new mobiletechnologyismoredependentonsoftware than traditional mobile networking. Thisincreases the potentialfor exploitation of 5Gnetwork infrastructure. BuildingSecurityforthe5GWorld As5Gbecomesmore prevalent and usable, business adoption will proliferate. The promise of 5G technology makes it an ideal choice for organizations that need to deploy monitoring and control solutions at remote locations. However, many of these same organizations – including criticalinfrastructure,healthcare,andsimilarindustries –arealsosomeof the ones most targetedand vulnerable to cyber threats. SecurityGen provides solutions that can aid these organizations in securely deploying IoT and other devices on 5G networks. This includes IoT security solutionstailored to industry-specific needsandcapableof protecting IoT devices from their initial connection to the network to blockingboth known and zero-day attacks.
