Network Security 802.1x
In order to enhance network security, it is recommended to implement 802.1x port-based network access control for both wired and wireless networks. This can be achieved by utilizing Windows Network Policy Server (NPS) and Cisco Identity Services Engine (ISE) to establish policy-based access control for users and network devices. To prevent unauthorized access, it is crucial to employ digital certificate-based protocols such as EAP-TLS and PEAP-MSCHAPv2. These protocols provide secure authentication and encryption mechanisms. Additionally, dynamic VLAN can be employed to enforce consistent security policies throughout the enterprise network, ensuring that both users and devices adhere to the established security measures. By implementing these measures, organizations can significantly bolster their network security and mitigate potential threats.
Enterprise Network Design
The network design aims to create a high availability data center network with minimal or no downtime during resource migration. The IP scheme is carefully designed to support continuous access to resources. Cisco VPC and Dell VLT technologies are employed to ensure fault tolerance and high availability. LACP is utilized to establish high throughput network links for both servers and network devices. The design also focuses on identifying and allocating necessary resources to enhance network performance. By implementing MST, spanning-tree calculations, CPU, and memory utilization are reduced, contributing to improved network efficiency. Overall, this network design optimizes reliability, availability, and performance within the data center environment.
Multi Cloud Migration & Connectivity
The Multi Cloud Migration & Connectivity project aims to enhance global access, streamline management, and improve efficiency while reducing costs in a hybrid environment. The migration involves transferring on-premise Active Directory (AD) users to Azure AD for seamless Single Sign-On (SSO) capabilities and simplified management. To optimize connectivity, Express Route and VPN Gateway are implemented, enabling secure and high-performance connections between on-premise infrastructure and the cloud. Furthermore, Microsoft 365 is deployed to centralize end-point device management and enforce policies across the organization. The project also encompasses migrating on-premise Exchange and SharePoint to Microsoft 365, facilitating a comprehensive cloud-based collaboration and communication solution. Finally, VMware ESXi virtual machines are migrated to Azure, enabling scalable and flexible infrastructure in the cloud.
