Mobile operators are racing to upgrade their networks with 5G connectivity while at the same time expanding 4G LTE coverage throughout the world. Though the latest generations of cellular technology offer faster performance and other benefits over their predecessors, they're vulnerable to some of the same security flaws. A report released Thursday by Positive Technologies explains how and why existing 4G and new 5G networks can be hurt by Denial-of-Service (DOS) attacks in particular. For its report "Security Assessment of Diameter Networks 2020," Positive Technologies simulated external attacks against 28 telecom operators in Europe, Asia, Africa, and South America during 2018 and 2019. Specifically, the company looked at 4G and 5G networks using Diameter signaling protocol, a method for coordinating data among different Internet Protocol (IP) network elements.

With the emergence of new technologies, the networking field is transforming rapidly. The epicenter of networking has shifted to clouds from datacenters. Similarly, the focus of networking has also moved towards mobile devices. In the upcoming years, tech trends will hugely impact the way a business operates and bring the rise of Industry 4.0.
Top Networking Tech Trends
1. 5G and WI-FI 6
Undoubtedly, the deployment of next-generation wireless networking will be around the corner. In the arena of mobile devices, 5G is set to rewrite the new technological possibilities. It will uncover the true power of augmented reality and IoT.
On the other hand, the next journey of the WI-FI Standard - WI-FI 6 or 802.11ax will become the step for a non-stop innovative world. It will add density, flexibility, scalability, and efficiency for increasing the internet speed of multiple connected devices. That will in return improve the working capabilities of businesses.
As the name suggested, SD-WAN is the software-defined approach for managing WANs. It can lower operating costs while amplifying the usage of resources in multiple deployments. It increases the security level for applications and enables admin to use bandwidth efficiently. It will become the standard format for wide area networks and will help in connecting public cloud resources and branch offices.
3. Secure Access Service Edge (SASE)
SASE is a new networking technology that converges functions of different security and network solutions into one global cloud service. It is an architectural alteration of networking and security that supports IT to offer prompt, holistic, and versatile service to the digital business. It amplifies the security postures, improves access performance, and diminishes operational complexity. It helps organizations to develop new products faster and respond to business needs or changes.
4. IoT/Edge Networking
In comparison to traditional cloud computing, edge computing is the idea to bring data and computers much closer to the end-users. It reduces the need for long-distance communication among client and server, and lessen the cost of bandwidth. It will remain to achieve drift in companies while they decentralize their networks.
5. Automation in Networking
Network automation is the process that automates security and network to maximize the functionality and efficiency of the network. It will help IT companies to deploy applications faster. It is set to take the digital transformation to the next step by automation of network and security operations. It reduces the risk of downtime and failure of the network while making the management faster, simpler, and easier.
Connecting to Future Networking
Based on the trends that will reshape the networking world, we are going to see a significant change in the tech landscape. 2021 will be transformative for every person around the world. Several long-held concepts and infrastructure will be replaced by new ones making the network a vital asset to the business. Besides, the organizations are ready to take advantage of them in a way that was never imagined before. For any question or concern, have an IT consultation from the experienced.

Enhanced security and privacy are cornerstones of 5G Core, but service providers still need to be able to capture quality, actionable data to secure the end-customer experience. Specifically, I’m referring to the data needed to perform troubleshooting, monitoring, customer care and analytics for marketing campaigns. But can this be done in 5G Core using traditional probing methods, without breaching security? The 3GPP standardization for 5G considers enhanced security to be an essential network component. Imagine, for a moment, that we live in a world where it’s common for open heart surgery to be conducted remotely, and I’m sure you’ll agree. The need for a secure, reliable network has resulted in the introduction of a new Service Based Architecture (SBA) that utilizes encrypted interfaces between network functions (NFs). Traffic between network functions is deployed in a cloud native 5G Core Kubernetes node and will not be visible outside the cluster, meaning traditional probing solutions are unsustainable.

A Software-defined Wide Area Network (SD-WAN) is an evolution of traditional WAN that allows businesses to leverage different networking options and transport services to connect users to applications. This includes the MPLS, LTE and broadband internet services. The SD-WAN is a better, more efficient means of supporting latency-sensitive applications. Enterprise customers can make use of this new network to increase network and application performance and/or lower costs, all of which contribute to improved user experience.
