Building a Comprehensive Identity & SaaS Security Framework

Overview

Identity and access management represents the critical foundation for insider risk mitigation. This playbook guides you through implementing a comprehensive framework that secures identities, governs SaaS applications, and establishes zero trust principles across your organization.

Identity and access management failures are a leading cause of data breaches, with privileged credential compromise representing a significant attack vector. Modern organizations typically use dozens of SaaS applications with varying levels of visibility and control. The Identity pillar accounts for 15% of your overall insider risk posture but serves as a force multiplier for all other security controls.

Phase 1: Discovery and Assessment (Weeks 1-2)

Current State Assessment

Begin by conducting a comprehensive inventory of your identity and access landscape:

Identity Infrastructure Audit:

  - Multi-factor authentication (MFA) deployment status

Account Analysis:
  - Total user accounts and service accounts
  - Privileged account inventory and usage patterns
  - Dormant and stale account identification
  - Shared account usage and justifications
  - External user and contractor access

SaaS Application Discovery: Use multiple discovery methods to identify all SaaS applications:

Discovery Tools and Techniques:

# Network-based discovery
