OCC and AWS Create Large-Scale Identity Governance for Financial Industry

management.
Role-Based Access Control (RBAC) enforces consistent access control policies across OCC’s AWS footprint, reducing redundancies and streamlining the entitlement process. Entitlement approvals became faster and easier with RBAC, eliminating the need for multiple approvals for each account and resource.
Automated lifecycle management simplified onboarding and offboarding processes for users, reducing the time required for new user provisioning while improving security posture through automated role revocation.
Continuous monitoring and alerting capabilities provide real-time visibility into IAM user behaviors, flagging anomalous access patterns or permissions changes for immediate remediation. This proactive approach enhances security posture by enabling quick response to emerging threats.
The Result: Streamlined Governance, Strengthened Security
By transitioning to AWS IAM Identity Center, OCC achieved a significant reduction in operational complexity while enhancing security controls. Governance tasks that previously required days of manual effort became automated processes, freeing up valuable resources within the Security and Governance teams for higher-value strategic initiatives.
Access reviews and audits now take a fraction of the time, thanks to the centralized identity management and RBAC capabilities provided by IAM Identity Center. This efficiency not only reduces the burden on OCC’s teams but also ensures compliance with stringent regulatory requirements for auditability and access controls.
Furthermore, the proactive monitoring and alerting features of IAM Identity Center empower OCC’s security teams to detect and respond to potential threats in real-time, improving incident response times and overall security posture.
In conclusion, the collaboration between OCC and AWS to architect an enterprise-scale identity governance framework demonstrates that complexity and governance can coexist harmoniously in critical financial infrastructure. By leveraging the capabilities of AWS IAM Identity Center, OCC has successfully modernized its access management approach, reducing operational overhead, improving security controls, and ensuring compliance with regulatory mandates. This case study serves as a blueprint for other enterprises operating at scale to enhance their governance and security posture in the cloud.
