CIS · Control 4.3 · Priority: critical · Component: Protect

### What this control covers

Configure automatic session locking on enterprise assets after a defined period of inactivity. For general purpose operating systems, the period must not exceed 15 minutes. For mobile end-user devices, the period must not exceed 2 minutes.

### Why it matters

Endpoint posture (encryption, EDR, OS patch state) is also the most common evidence customers ask for in their vendor reviews.

### How to implement

#### AWS

Bake hardening into **EC2 Image Builder** + **AMI accounts**; use **Systems Manager Fleet Manager** for inventory and patch state.

#### Azure

**Intune** enrolment for laptops + phones; Conditional Access requires "compliant device" before any corporate app loads. EDR via **Defender for Endpoint**.

#### GCP

**Org Policy Service** for guardrails and **Config Validator** in CI to pre-check Terraform plans against policy as code (Rego).

#### Google Workspace

**Endpoint Management** (basic/advanced) for BYOD/COPE; require screen lock, disk encryption and OS minimum; block sign-in on jailbroken devices.

### Evidence to collect

-   `infra_scan` — See the iCompaas Evidence library for the canonical source for this evidence type.
-   `user_device_scan` — Output from your MDM/EDR (Intune, Jamf, Kandji) showing managed-device count, posture and last-check-in.

Infrastructure posture tooling (AWS Config, Azure Policy, Nessus) verifies platform hardening. Endpoint compliance telemetry (Intune, Jamf) proves managed coverage. Focus: Configure Automatic Session Locking on Enterprise Assets.

### Quick checklist

-   Configure — End User / Mobile
