Identity Incident Investigation

Identity Incident Investigation Training by Tonex

Compromised identities can provide attackers with access that resembles ordinary authorized activity, making careful investigation essential. Identity Incident Investigation Training by Tonex develops methods for analyzing sign-ins, account changes, authentication decisions, privileged roles, session use, and delegated application access. Participants learn to correlate identity provider records with application and cloud events, assess evidence limitations, and document the sequence of suspicious activity.

Evidence-based identity investigations improve cybersecurity by revealing unauthorized access and potential privilege abuse. They strengthen cybersecurity operations by supporting targeted session revocation, credential protection, stakeholder coordination, and lasting authentication control improvements.

A practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in identity incident investigation projects.

Learning Objectives

• Explain identity attack patterns and the importance of authentication evidence.
• Identify sign-in, session, application consent, and privileged access records.
• Correlate identity provider events with cloud and application activity.
• Assess suspected account takeover using corroboration and documented context.
• Preserve identity evidence and distinguish confirmed activity from uncertainty.
• Coordinate targeted containment, recovery, and identity governance improvements.
• Improve cybersecurity incident investigations through rigorous identity evidence interpretation.

Audience

Course Modules

Module 1: Identity Threats and Investigation Scope

• Review account takeover scenarios and suspicious identity behavior patterns
• Identify affected identities, applications, service accounts, and tenants
• Define initial incident windows and investigation ownership boundaries
• Assess authorization and privacy requirements for account evidence
• Prioritize privileged accounts and sensitive business application access
• Document competing hypotheses before reaching account compromise conclusions

Module 2: Authentication and Sign In Evidence

• Examine successful and failed authentication events for anomalies
• Review multifactor authentication outcomes and unusual verification changes
• Assess location and device context without unsupported identity assumptions
• Correlate sign-in sequences with legitimate organizational work patterns
• Investigate account recovery and authentication method modification events
• Preserve original identity provider records with acquisition details

Module 3: Sessions Tokens and Application Access

• Review session establishment, refresh events, and available termination evidence
• Investigate suspicious delegated application consent and permission grants
• Correlate unusual token usage with relevant access audit records
• Identify unauthorized application integrations with excessive identity privileges
• Consider session visibility gaps and provider specific logging limitations
• Document investigation findings without exposing reusable authentication secrets

Module 4: Privilege and Federation Investigation

• Examine privileged role assignment changes and approval histories
• Review unusual identity federation configuration and trust updates
• Trace administrative changes back to authenticated actor records
• Assess service account usage and noninteractive authentication anomalies
• Correlate elevated access with subsequent sensitive resource activity
• Distinguish expected emergency access from unauthorized privilege use

Module 5: Incident Timeline and Containment

• Build identity timelines using synchronized records and session identifiers
• Validate suspicious events against corroborating application and cloud data
• Identify impacted accounts, permissions, resources, and potential exposures
• Coordinate session revocation and credential changes with accountable owners
• Preserve necessary evidence before implementing disruptive response actions
• Document containment decisions, business dependencies, and remaining uncertainty

Module 6: Reporting and Identity Hardening

• Prepare defensible summaries with clear event provenance and confidence
• Identify recurring authentication weaknesses and excessive access permissions
• Recommend stronger conditional access and account recovery governance
• Review privileged access monitoring and application permission oversight
• Record detection gaps and needed identity evidence retention improvements
• Maintain reusable case templates and postincident identity security reviews
