## 5 New Trends and Future Research Directions in Enterprise Networking
### Cybersecurity Mesh Architecture (CSMA)  
Cybersecurity means protecting the software, hardware, network, and data from unauthorized access and accidental attack or damage. Since its inception, the field of cybersecurity has developed to be dynamic and challenging [89; 90]. Currently, CSMA includes a variety of tools and techniques, functioning to protect systems, networks, and data from a broad range of cyber threats. Figure 12 shows CSMA architecture and different aggregated layers. With every new security solution, there are more ways for attackers to penetrate past existing security features. Thus, CSMA proves to be of great advantage to large organizations by relying on data aggregation and tool integration approaches [110].  
Each layer of CSMA platform can communicate with the layers above and below it by grouping existing security and analysis devices into stratified layers. As a result, a functional structure is created that enables communication and cooperation amongst highly distributed networks. Security activities are therefore made more efficient by the centralized dashboards and controls that receive all of this information. Additionally, CSMA features AI-supported automation and unified threat intelligence awareness to create a dynamic security system that can circumvent potential attackers [89]. Modern enterprise requires a network to connect its on-premises servers, cloud services, tools, and home and edge devices [111]. Therefore, network security revolves around protecting these geographically distributed resources.  
In summary, much has been discussed about advancements in enterprise networking which are shaping the current landscape. Other technologies such as artificial intelligence (AI)-powered IBN architecture [94]; Wi-Fi 6; its successor, Wi-Fi 7; or IEEE 802.11 be and beyond 5G (B5G) networks [112; 113] are the latest technologies provisioned to deliver seamless wireless access for businesses. They possess the advantage of providing higher bandwidth and supporting more users per access point. These cutting-edge wireless solutions have been optimized to provide ultra-fast speed compared to wired access architecture. With Wi-Fi 7, more connected users and devices are supported without affecting performance, while allowing data to move securely over wireless networks.
