The Challenge
Organizations often struggle with visibility into user access patterns across multiple systems, making it difficult to identify security risks, compliance issues, and access anomalies. Security teams face significant challenges in managing access governance effectively.
Key Issues
- Limited visibility into access patterns across disparate systems
- Difficulty identifying potential security risks and compliance issues
- Inability to detect segregation of duties conflicts efficiently
- Manual, time-consuming access review processes
- Lack of meaningful metrics for leadership reporting
Goals
- Create a comprehensive view of access across all enterprise systems
- Automate the identification of access risks and anomalies
- Reduce time required for access reviews by at least 50%
- Improve compliance posture with clear evidence for auditors
- Provide actionable insights to security leadership
The Solution
I designed and implemented a comprehensive dashboard that aggregates access data from multiple enterprise systems, visualizes access patterns, and identifies potential security risks. The solution transforms raw access data into actionable insights through advanced analytics and visualization techniques.

Key Components
The solution consists of several integrated components that work together to provide comprehensive access governance:
- Data Collection Layer: Python scripts that extract access data from various enterprise systems
- Data Processing Engine: ETL processes that transform and normalize access data
- Analytics Engine: Advanced algorithms that identify patterns, anomalies, and risks
- Visualization Layer: Interactive Tableau dashboards that present insights in an actionable format
- Reporting Module: Automated reports for compliance and leadership
Implementation Process
- Data Collection and Integration: Developed Python scripts to extract access data from Active Directory, ERP systems, and custom applications, then load it into a centralized database.
- Data Analysis and Modeling: Performed extensive analysis to identify patterns, anomalies, and potential risks, including excessive permissions, segregation of duties conflicts, and unusual access patterns.
- Dashboard Development: Created an interactive Tableau dashboard with multiple views and filters to allow security teams to explore the data from different angles.
- Testing and Validation: Conducted thorough testing with security teams to validate findings and refine the dashboard based on user feedback.
- Deployment and Training: Deployed the solution and provided training to security teams on how to use the dashboard effectively.
Interactive Dashboard
The Access Governance Dashboard provides multiple interactive views that allow security teams to explore access data from different perspectives.
