In today’s digital environment, organizations must ensure that users have the right level of access to critical systems and data while maintaining security and compliance. Identity and Access Governance (IAG) plays a crucial role in managing and monitoring user access, enforcing security policies, and ensuring regulatory compliance.
Effective Identity and Access Governance helps organizations reduce security risks, prevent unauthorized access, and streamline audits by implementing structured access control policies. Understanding key governance concepts is essential for IT and security professionals to maintain visibility and control over user identities and permissions.
Some fundamental Identity and Access Governance key terms include:
- Access Certification – Periodic review and validation of user access rights.
- Role Management – Assigning and managing user roles based on job functions.
- Segregation of Duties (SoD) – Preventing conflicts of interest by restricting access to critical tasks.
- Audit & Compliance – Ensuring adherence to regulatory frameworks and internal policies.
- User Access Reviews – Conducting regular assessments of user permissions to detect risks.
- Policy Enforcement – Defining and applying security rules to manage identity and access.
- Identity Governance & Administration (IGA) – Automating identity and access lifecycle processes.
- Risk-Based Access Control – Adjusting user access based on risk levels and behavioral analysis.
By implementing strong Identity and Access Governance practices, organizations can enhance security, improve operational efficiency, and meet regulatory requirements. This guide will explore these key terms in detail to help organizations build a more secure and compliant identity management framework.
Here’s a list of key terms commonly used in Identity and Access Governance (IAG):
1. Core Concepts in Access Governance
- Access Governance (AG) – The framework for managing and monitoring user access rights across an organization.
- Identity Governance and Administration (IGA) – Policies and processes to manage user identities and access.
- Identity Lifecycle Management (ILM) – Managing user identities from onboarding to offboarding.
- Access Control – The process of restricting access to resources based on policies.
- Access Management (AM) – Ensuring users have the right access at the right time.
- Entitlement Management – Defining and managing user access permissions.
- Segregation of Duties (SoD) – Ensuring no user has conflicting permissions that could lead to fraud.
2. Access Review & Certification
- Access Reviews – Periodic audits to validate user access rights.
- Access Certification – A formal process to review and approve user access to resources.
- Role-Based Certification – Reviewing access based on job roles.
- Time-Based Access Review – Periodic access verification to ensure ongoing compliance.
- Continuous Monitoring – Real-time tracking of access rights and policy violations.
- Orphan Accounts – Accounts that remain active after a user has left the organization.
3. Role & Policy Management
- Role-Based Access Control (RBAC) – Granting access based on predefined roles.
- Attribute-Based Access Control (ABAC) – Granting access based on attributes like department or location.
- Policy-Based Access Control (PBAC) – Defining access through security policies and compliance rules.
- Dynamic Role Management – Updating user roles automatically based on job changes.
- Access Policies – Rules defining who can access what resources.
- Least Privilege Principle – Providing only the minimum access required for a user’s role.
4. Identity & Compliance Monitoring
- Identity Governance – Managing user identities and access policies to meet compliance.
- Privileged Access Governance – Monitoring high-level administrative access.
- Audit Logging – Recording all access-related actions for compliance tracking.
- Compliance Reporting – Generating reports for audits and regulatory compliance.
- User Behavior Analytics (UBA) – Detecting anomalies in user access patterns.
- Risk-Based Access Control – Adjusting access permissions based on risk levels.
- Access Anomalies Detection – Identifying unusual access activities that may indicate security threats.
5. Automation & Integration
- Identity Synchronization – Ensuring consistent user access data across multiple systems.
- Self-Service Access Requests – Allowing users to request and manage their own access rights.
- Just-In-Time (JIT) Access – Temporarily granting access when needed.
- Access Workflow Automation – Automating access approval and review processes.
- Role Mining – Analyzing access patterns to define roles and optimize access rights.
How Access Governance Works in Practice
Access Governance (AG) ensures that users have appropriate access to systems and data while maintaining security and compliance. Let’s break down how the key concepts are applied in real-world scenarios:
1. Access Governance Framework
How It Works:
Access governance centralizes access management across an organization, ensuring that:
✅ Users have the right access at the right time (Access Control)
✅ Permissions are reviewed regularly (Access Certification)
✅ Compliance requirements are met (Audit Logging & Compliance Reporting)
Example:
A financial services company implements an Identity Governance and Administration (IGA) system to enforce access policies. All employee access requests must go through an automated approval process, ensuring only authorized personnel can access sensitive financial records.
2. Access Review & Certification
How It Works:
Organizations must periodically review user access to detect and revoke unnecessary permissions.
- Access Reviews – Managers review employee access to critical systems.
- Access Certification – Formal approval of access rights to ensure compliance.
- Orphan Accounts – Identifying and disabling accounts that belong to former employees.
Example:
A healthcare provider conducts quarterly access reviews. The security team finds that a former employee still has access to patient records, which violates HIPAA regulations. Their access is immediately revoked, and an audit report is generated.
3. Role & Policy Management
How It Works:
Users are granted access based on predefined roles, attributes, and policies:
- Role-Based Access Control (RBAC) – Access assigned based on job role (e.g., HR staff can view payroll, but IT cannot).
- Attribute-Based Access Control (ABAC) – Access controlled based on attributes (e.g., location, department).
- Least Privilege Principle – Users only get the minimum necessary access.
- Segregation of Duties (SoD) – Prevents users from having conflicting permissions (e.g., an employee cannot both approve and process payments).
Example:
An HR system follows RBAC, allowing recruiters to access job applicant data, while payroll staff can access salary information. If an employee changes roles, their permissions update automatically (Dynamic Role Management).
4. Compliance & Risk Monitoring
How It Works:
Organizations use audit logs, risk scoring, and anomaly detection to monitor access and ensure compliance.
- Privileged Access Governance – Monitoring high-level administrative access.
- User Behavior Analytics (UBA) – Detecting suspicious access patterns.
- Audit Logging & Compliance Reporting – Keeping records for regulatory audits.
- Access Anomalies Detection – Identifying unusual access, such as login attempts from unauthorized locations.
Example:
A bank uses Risk-Based Access Control (RBAC) to monitor logins. If an administrator logs in from an unusual IP address, the system triggers an alert and requires additional authentication.
5. Automation & Integration
How It Works:
Automating access governance reduces security risks and improves efficiency:
- Identity Synchronization – Ensures consistent user access data across multiple systems.
- Just-In-Time (JIT) Access – Temporary access granted for specific tasks.
- Self-Service Access Requests – Employees request and manage their own access via an approval system.
- Access Workflow Automation – Automates onboarding, approvals, and revocation processes.
- Role Mining – Uses data analytics to identify common access patterns and optimize role definitions.
Example:
A cloud service provider automates JIT access for IT admins. Instead of keeping permanent privileged access, admins must request temporary access, which is logged and revoked after the task is completed.
Conclusion
✅ Access Governance ensures that organizations control user access efficiently.
✅ Automated access reviews, policies, and monitoring help maintain security & compliance.
✅ Implementing role-based access, risk monitoring, and automation minimizes security threats.
