Security Operations Insider Investigation Playbook
eBook
A step-by-step investigation framework for analyzing insider risk using behavioral context, automated timelines, and risk-based prioritization
This playbook provides a structured investigation model for detecting, analyzing, and responding to insider risk hidden within legitimate activity.
Insider threats increasingly operate through valid credentials, trusted access, and approved workflows. Traditional detection models evaluate events in isolation and within short time windows, making slow-moving or low-noise insider activity difficult to detect. As environments expand to include service accounts and AI agents, the challenge of identifying meaningful risk continues to grow.
This playbook shows how to move from isolated signals to behavior-driven investigation. It provides a repeatable workflow for building context, analyzing machine-built timelines, assessing risk progression, and making defensible decisions. The result is faster investigations, reduced noise, and more consistent prioritization of real insider risk.
Key Questions This Playbook Helps You Answer
- How do you determine whether a signal is worth investigating or just noise?
- What does normal behavior look like for a user, service account, or AI agent?
- How do you identify behavioral patterns that indicate risk is developing?
- How do automated timelines change how investigations are performed?
- What signals indicate that insider risk is expanding or becoming actionable?
- How do you move from detection to a fast, defensible decision?
How Do Exabeam Solutions Support Insider Investigations?
New-Scale Fusion applies behavioral analytics, dynamic risk scoring, and automation to help analysts investigate insider risk without manual correlation. User and entity behavior analytics (UEBA) and Agent Behavior Analytics (ABA) establish behavioral baselines across users, service accounts, and AI agents. Automated timelines correlate activity into investigation-ready sequences, while Exabeam Nova surfaces behavioral patterns, highlights escalation points, and guides response actions so analysts can focus on decisions instead of data assembly.
