Threat Modeling for 5G Cybersecurity

MOST RECENT POSTS

5G structures are the next step in the development of mobile networking. We are about to embark on a next generation system level that emboldens mobile communications with trials and ongoing scale sales. The fifth generation wireless system (5G) seeks to give substantial performance improvements to the market. 5G networks must offer resources not only for voice and data communication, but also for new industries and a variety of devices and applications to keep our generation interconnected.

Research and regulation have started in for 5G. The technology will accelerate the implementation of home automation, smart building and smart cities. However, we are not there yet. The definition of 5G mobile networks has not yet achieved regulation phase in the 3GPP.

The progression of LTE is a critical part of 5G. Nevertheless, 5G will enhance all parts of the network, such as core and management systems, as well as all procedure layers ranging from radio to applications. Therefore, security is possibly altered universally.

The truth is that 5G will also be built upon existing generation systems. Worldwide telecommunication systems are notoriously grouped with older technologies, built on top of or integrated with each other for many reasons, such as:

  • Requirements for bequest backing
  • Speed of rollouts that cannot be simply turned off or discharged without ample planning

Present 4G cellular systems provide a high level of security and reliability for users and operators. Second generation (GSM) systems were the first to have regulated, fixed security functions, which then progressed through 3G and now 4G networks. Users might think of 5G networks as primarily a numerical progression such as prior versions, however, 5G security will be a qualitative surge forward to meet the mandates of a networked civilization.

Security for 5G

5G is more like a notion rather than a technology. There are no detailed, given security requirements for 5G and no new procedures have been planned from a security requirements standpoint. 5G constructs on newer technologies such as: software-specified networking and network functions virtualization, and developing cloud technologies where feasible. As the security of these new technologies and tasks is not within 5G’s square, 5G security connects to the secure design, architecture, build, design and preservation of all applicable technologies and modules that reinforce 5G.

The evolution of older technologies will be a time-consuming route, so 5G will be counting on these mature, perhaps less protected, technologies for some time. Besides the security disputes generated by new technologies such as virtualization and cloud, this suggests that 5G security is a massive subject matter. Certain devices and techniques are necessary to assist identify the related threats, risks and mitigations that are required for 5G security policy. The intricacy in safeguarding 5G is surely not to be misjudged.

5G and Cybersecurity

Today’s systems host several standards. The availability of these standards through the internet has already invited cyber attackers, alternative markets, crime syndicates and and cybercrime. The data hosted in, and created by, the 5G system are projected to be even higher, and the resources will be even more appealing to hackers who perform different types of attacks. Additionally, contemplating the potential effects of an attack, the harm may not be restricted to a business; it could have a serious influence on public safety. Here are some of the ways in which 5G networks are more vulnerable to cyber-attacks than their previous versions:

  • The impressive increase of bandwidth that makes 5G happen, produces further possibilities of attack. Substantially, inexpensive and tactical transmitters installed throughout metropolitan regions develop new hard objectives. Functionally, these cell locations will use 5G’s dynamic spectrum sharing capacity in which various flows of information share the bandwidth in slices with their own differing amount of cyber risk. When software allows the roles of the network to shift actively, cyber protection must be proactive, consistent and efficient.
  • The susceptibility generated by connecting various smart devices to the IoT. Strategies are proceeding for a varied and superficially infinite list of IoT supported activities, all of which are distinctively susceptible. Hackers can uncover further vulnerable IoT devices into which they could install exploitation software.
  • Even if it was possible to secure the software vulnerabilities within the network, this network can also be controlled by software that can be susceptible to threats and vulnerabilities. Cyber attackers that access the software management tools can also control the network.

ThreatModeler for 5G cybersecurity

A crucial stage in cybersecurity best practice and taking a proactive approach towards cyber attackers is threat modeling. Threat Modeling allows security experts to think like a hacker and have a better understanding of how to gain access to your infrastructure. It allows enterprises to clearly visualize their attack surface to make informed risk management decisions.

Threat Modeling helps organization to foresee their attack surface and map out the different threats and attack vectors their system may contain. Threat Modeling typically uses process flow diagrams to lay out the various components, user behaviors and communication flows. As 5G cybersecurity becomes a pressing topic with the technology’s pervasive nature, threat modeling will become a useful practice to ensure application components have adequate security controls.

ThreatModeler enables security teams to build threat models out of the box with content libraries containing updated content from reliable sources including OWASP, CAPEC, the NVD, AWS and Azure. To learn how ThreatModeler can help your organization to achieve data with security and integrity, we recommend scheduling a live demo. You can also contact us to speak with a threat modeling expert.
