Your annual IAM audit just concluded. The report shows 3,847 active user accounts, 156 service accounts, and 847 different role assignments across various systems. Ninety-two percent of users completed their annual access review, and privileged access is properly documented. The auditors are satisfied, but you still can’t answer basic questions like “Who can access our customer database?” or “How would an attacker escalate privileges in our environment?”

Traditional IAM assessments focus on compliance and user inventory while missing the identity-based risks that enable modern attacks. They count users and permissions without understanding how those permissions create attack paths or expose critical assets.

Building on our Security Posture Management approach, let’s explore how to conduct IAM assessments that actually identify and address identity-related security risks.

The Limitations of Compliance-Focused IAM Assessments

Checkbox Security vs. Risk Assessment

Traditional IAM audits focus on compliance requirements:

  • User account inventory and documentation
  • Annual access reviews and approval workflows
  • Privileged access documentation and approval processes
  • Password policy compliance and multi-factor authentication deployment

What they miss:

  • How identity permissions create actual attack paths
  • Cross-system privilege relationships and escalation opportunities
  • Service account risks and automated access patterns
  • Identity federation and trust relationship security implications

Example: An access review confirms that John Smith has appropriate access to the HR system for his role. What it doesn’t reveal is that the HR system has administrative access to Active Directory, making John’s account a potential pathway to domain administrator privileges.

The Attack Path Reality

Modern identity-based attacks exploit permission relationships and trust boundaries:

  • Initial compromise of low-privilege accounts
  • Lateral movement using legitimate identity permissions
  • Privilege escalation through permission inheritance and service account abuse
  • Persistence through identity manipulation and backdoor account creation

Identity risks that enable these attacks:

  • Excessive permissions that violate least privilege principles
  • Service accounts with broad access and weak authentication
  • Cross-system trust relationships that enable privilege escalation
  • Identity federation configurations that expand attack surfaces

Comprehensive IAM Security Assessment Framework

Identity Architecture Analysis

Start with understanding your identity ecosystem:

Identity system inventory:

  • All identity providers and their relationships (Active Directory, cloud identity providers, LDAP, etc.)
  • Authentication mechanisms and their security implementations
  • Single sign-on configurations and trust relationships
  • Identity synchronization and federation architectures

Trust relationship mapping:

  • Forest and domain trusts in Active Directory environments
  • Cloud identity provider federations and trust configurations
  • Service-to-service authentication and authorization mechanisms
  • Cross-platform identity integration and permission delegation

Example assessment finding: The organization uses three different identity providers with complex federation relationships, creating multiple paths for privilege escalation and making it difficult to track actual access permissions across the environment.

Permission and Privilege Analysis

Map actual access patterns and permission inheritance:

Effective permissions analysis:

  • Direct permissions granted to users and groups
  • Inherited permissions through group membership and role assignments
  • Service account permissions and their usage patterns
  • System-level permissions and administrative access grants

Privilege escalation path analysis:

  • Opportunities for horizontal privilege escalation (accessing similar-level resources)
  • Vertical privilege escalation pathways to administrative access
  • Cross-system privilege escalation through service accounts and delegation
  • Persistence mechanisms using identity permissions

Access pattern assessment:

  • Actual resource access patterns vs. granted permissions
  • Unused permissions that create unnecessary risk exposure
  • Excessive permissions that violate business need requirements
  • Temporal access patterns that may indicate misuse or compromise

Service Account and Non-Human Identity Analysis

Assess automated and service-based identity risks:

Service account inventory and analysis:

  • Service account discovery across all systems and platforms
  • Authentication mechanisms and credential management for service accounts
  • Permission grants and actual usage patterns for automated access
  • Service account lifecycle management and monitoring capabilities

Application and system identity assessment:

  • API keys, certificates, and other non-password authentication mechanisms
  • Machine identity management and certificate lifecycle processes
  • Container and cloud workload identity configurations
  • DevOps and CI/CD pipeline identity and access management

Cross-system service relationships:

  • Service accounts that access multiple systems or platforms
  • Delegation and impersonation capabilities for service accounts
  • Service account permissions that enable lateral movement or privilege escalation
  • Monitoring and detection capabilities for service account misuse

Advanced Assessment Methodologies

Attack Path Modeling for Identity

Map realistic attack scenarios using identity permissions:

Identity-based attack simulation:

  • Model attack paths starting from compromised user accounts
  • Identify permission chains that enable lateral movement and privilege escalation
  • Assess detection capabilities for identity-based attacks
  • Evaluate response procedures for compromised identity scenarios

Privilege escalation analysis:

  • Direct privilege escalation through role inheritance and group membership
  • Indirect escalation through service accounts and delegation mechanisms
  • Cross-platform escalation using federation and trust relationships
  • Persistent access establishment using identity manipulation techniques

Behavioral Analysis Integration

Combine permissions analysis with actual usage patterns:

Access pattern analysis:

  • Normal access patterns for users and services
  • Anomalous access that may indicate compromise or misuse
  • Unused permissions that create unnecessary risk exposure
  • Access patterns that suggest privilege creep or role confusion

Risk scoring based on behavior:

  • Users with high-risk permission combinations
  • Service accounts with broad access and unusual usage patterns
  • Cross-system access patterns that suggest lateral movement potential
  • Identity configurations that deviate from security best practices

Automated Discovery and Analysis

Use tools and automation to scale identity assessment:

Identity discovery automation:

  • Automated discovery of user accounts across all systems and platforms
  • Service account identification and permission mapping
  • Group membership and role assignment analysis
  • Cross-system identity correlation and relationship mapping

Permission analysis automation:

  • Effective permissions calculation across complex inheritance structures
  • Attack path discovery using graph analysis and modeling techniques
  • Risk scoring based on permission combinations and access patterns
  • Continuous monitoring for identity configuration changes and new risks
