Direct weaknesses embedded within identity components—authentication mechanisms, federation protocols, token lifecycle management, session handling, and machine identity systems. These are exploitable vulnerabilities in the foundational building blocks of identity infrastructure.
Architectural Failure Modes
System-level design flaws that create predictable, reproducible attack paths across identity ecosystems. These are structural weaknesses that enable lateral movement, privilege escalation, and persistent access even when surface-level controls appear functional.
Consolidates the two deepest layers of identity breakdowns: failures built into the system, independent of human error—the structural weaknesses attackers exploit even when surface controls look correct.
Authentication & Access Control Failures
Weak or Inconsistent MFA Enforcement
MFA gaps across applications, privileged roles, or legacy endpoints create exploitable authentication surfaces.
Attack Impact: Credential compromise leads directly to authentication abuse and account takeover.
Legacy Authentication Pathways Enabled
POP/IMAP, basic authentication, WS-Trust, and proprietary SSO protocols remain active in production environments.
Attack Impact: Silent takeover vectors and complete MFA bypass opportunities for threat actors.
Long-lived refresh tokens remain valid indefinitely, never rotated, and lack context-binding mechanisms. Weak session governance compounds the risk.
Token persistence beyond intended scope
Identity drift over extended periods
Replay attack vulnerability windows
Federation Trust Misconfiguration
Improper issuer, audience, and signature validation combined with stale metadata creates federation vulnerabilities.
SAML assertion replay attacks
OIDC token manipulation vectors
Cross-tenant trust exploitation
Privilege & Permission Architecture Failures
1
Overprivileged App & API Permissions
Application roles, Microsoft Graph permissions, and service principal rights granted far beyond operational necessity. Single credential compromise cascades into broad privilege escalation.
2
Under-Specified Role Boundaries
Cloud IAM roles designed overly broad or implemented inconsistently across environments. Creates unpredictable privilege elevation opportunities that evade detection.
3
Lack of Privilege Activation Guardrails
Administrative roles can be activated without approval workflows, risk-based checks, or time-bound constraints. Enables silent elevation without security team awareness.
Machine Identity Security Failures
73%
Organizations
Rely on static secrets for machine authentication
5x
Growth Rate
Machine identities outpacing human identities annually
Weak Machine Identity Security Architecture
Static secrets, plaintext API keys, and service account credentials stored in configuration files or environment variables. Machine identities granted excessive automation privileges without proper lifecycle management or credential rotation.
Cloud A overtrusts Cloud B without proper role reduction or scope limitation. Cross-cloud lateral pivot becomes trivial.
2
2
Poor Identity Plane Separation
Shared roles between human and machine identities. Overlapping permissions enable hybrid privilege escalation.
3
3
Incorrect Trust Boundaries
"Internal equals safe" assumptions persist in hybrid architecture. Internal and SaaS lateral movement opportunities multiply.
Visibility & Lifecycle Management Failures
1
Missing or Misconfigured Identity Logging
Unlogged federation events, absent PIM audit trails, and insufficient retention periods. Attackers achieve invisible persistence without triggering alerts.
2
Identity Drift Over Time
Privileges accumulate without lifecycle boundaries or recertification processes. Stale admin access becomes exploitable long after business need expires.
3
Overly Complex Identity Architecture
Multiple identity providers, half-migrated cloud IAM implementations, and orphaned directory connectors. Complexity confusion creates attacker opportunity.
Identity Attack Chain Impact
Technical and architectural failures directly enable progression through the Identity Attack Chain, creating exploitable pathways at multiple critical stages.
1
Stage 3: Credential Acquisition
Weak authentication and legacy protocols facilitate initial credential harvest
2
Stage 4: Authentication Abuse
MFA gaps and session weaknesses enable unauthorized authentication
3
Stage 5: Privilege Escalation
Overprivileged roles and weak boundaries allow vertical movement
4
Stage 6: Token Tampering
Federation misconfigurations enable token manipulation and replay
5
Stage 7: Lateral Movement
Cross-cloud trust and identity drift facilitate horizontal expansion
6
Stage 8: Persistence
Logging gaps and complex architecture enable undetected persistence
The design choices made at the infrastructure layer directly dictate whether credential compromise escalates into full breach scenarios or remains contained.
Weak design plus weak enforcement guarantees compromise
When architectural flaws combine with inadequate security controls, identity-based attacks succeed with near certainty. Defense in depth requires both layers.
Eliminating structural failures reduces blast radius of human error
Even when users fall victim to phishing or social engineering, robust identity architecture limits attacker movement and privilege escalation opportunities.
Modern cloud breaches exploit these exact weaknesses
Real-world threat actors consistently target technical and architectural identity failures as primary attack vectors in enterprise cloud environments.
