Mahipal 2fb6a9faff Rewrite 548 skill descriptions to the activation rubric
Each rewritten description now states both what the skill does (concrete
capability, named tools/artifacts) and an explicit when-to-use trigger,
improving agent discovery/activation. Grounded in each skill's own body;
changes confined to the `description` field only (bodies and all other
frontmatter untouched). Produced by a gated audit->rewrite->recheck loop
(548 -> 0 flagged) with a sampled anti-invention check (0 ungrounded).

Schema: 817/817 pass. Framework-ID gate: 0 defects.

Configuring Active Directory Tiered Model

Overview

Implement Microsoft's Enhanced Security Admin Environment (ESAE) tiered administration model for Active Directory. Covers Tier 0/1/2 separation, privileged access workstations (PAWs), administrative forest design, authentication policy silos, and credential theft mitigation.

When to Use

  • When deploying or configuring configuring active directory tiered model capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • Familiarity with identity access management concepts and tools
  • Access to a test or lab environment for safe execution
  • Python 3.8+ with required dependencies installed
  • Appropriate authorization for any testing activities

Objectives

  • Implement comprehensive configuring active directory tiered model capability
  • Establish automated discovery and monitoring processes
  • Integrate with enterprise IAM and security tools
  • Generate compliance-ready documentation and reports
  • Align with NIST 800-53 access control requirements

Security Controls

Control NIST 800-53 Description
Account Management AC-2 Lifecycle management
Access Enforcement AC-3 Policy-based access control
Least Privilege AC-6 Minimum necessary permissions
Audit Logging AU-3 Authentication and access events
Identification IA-2 User and service identification

Verification

  • Implementation tested in non-production environment
  • Security policies configured and enforced
  • Audit logging enabled and forwarding to SIEM
  • Documentation and runbooks complete
  • Compliance evidence generated
