Zero Trust with Conditional Access and MFA
Associate Consultant, Tata Consultancy Services (November 2022 to present)
Implemented Zero Trust through Conditional Access, MFA, Azure NPS and Identity Protection, governed with Privileged Identity Management and Access Reviews.
The problem
Access depended on network location and passwords, with no consistent check on who was signing in, from where and on which device.
What I did
Conditional Access policies decided access from the user, device and risk. MFA covered users, and the Azure NPS extension brought MFA to network access. Identity Protection scored sign-in risk. Privileged Identity Management made administrator roles time-limited, and Access Reviews checked regularly that people still needed their access.
The result
Access decisions follow identity, device and risk, and privileged access is limited in time and reviewed.
