Secure Cloud Infrastructure

Designed a secure cloud infrastructure to migrate on-premise workloads to the cloud. As a cloud security architect, I created a safe design for connectivity from an on-premise data center to the cloud. I assisted the project manager and core technical teams in developing migration strategies. Also, I developed a plan to allow secure access to web applications by partners and customers.

Migrated 35000 Remote Access Users to a One-time Password Solution

I was tasked with integrating remote access profiles with the enterprise directory and a one-time password solution. I liaised with different teams to seamlessly migrate remote access users to a one-time password solution in the cloud with zero downtime. This involved creating various profiles and aliases on remote access appliances and then doing network-level configuration to ensure the OTP servers are reachable from multiple locations across the globe so that users don't get blocked in case of an issue in one geographical area.

Integration of Remote Access Service with Azure MFA

I was responsible for the migration of MFA from MobilePASS to Azure MFA, leveraging the Azure infrastructure which we use. This involved doing a proof of concept on a test platform and sharing the results with the business. There were remote access gateways at nine locations worldwide, which I moved to use Azure MFA.

Integration of On-Prem AD with Azure AD

I successfully integrated on-prem AD with Azure AD and also created several conditional access profiles for security robustness and to ensure identity protection using risk-based policies. I also worked on federated identity to allow MS teams to collaborate with several partners.

Technology Refresh of an Internet Gateway Stack

As a routing, switching, and security expert, I developed a migration plan. It contained a low and high-level design and a runbook to replace the internet-facing ASA firewalls with SonicWall firewalls. It moved internet-exposed services behind a DMZ.
