Redesigning Network Architecture - Phase 01

Overview

The client, one of the most reputed law firms in the USA, Wanted to revamp its network design architecture. This activity aimed to identify anomalies, maximise performance, and keep an eye out for attacks while protecting the organisation’s data from any possible attack.

Problem Statement and Challenges

Being a Law Firm responsible for handling data from Fortune 500 organisations, the client wanted to be as vigilant as they could with their data security, which is why they wanted to amplify their network security and ensure that it is up to current standards.

Solution

We started with Remote Access Dial In User Service (RADIUS) and Terminal Access Controller Access-Control System Plus (TACACS+) authentication for 400 Network Switches, 06 Firewall and 02 Wireless Controller. Moving on, we also set up a Global Protect VPN for their Data Center using Palo Alto Networks, which 1000+ employees can use on the client’s side for remote access.

Upon the clients’ request, we migrated all 52 sites from the legacy router to a Software-defined Wide Area Network (SD-WAN). We also configured the standard access list for the virtual terminal or ‘VTY Line’.

Lastly, we managed to renew certifications for several applications in F5 Load Balancer, map them with existing server nodes and validate them afterwards.

• TACACS+/Radius Authentication
• Global Protect VPN In Data Centers
• SD-WAN Implementation for 52 sites
• Standard Access List Configuration For VTY Line

Results and Success Criteria

The client was delighted with the optimisation of the network and was completely satisfied with the functionality. Moreover, it improved productivity, secured the network and helped smooth overall business operations.
