**CIS Controls v8**·Control `4.12`·medium·Component: **Protect**

## What this control requires

> Ensure separate enterprise workspaces are used on mobile end-user devices, where supported. Example implementations include using an Apple® Configuration Profile or Android™ Work Profile to separate enterprise applications and data from personal applications and data.

> — CIS Controls v8, Control 4.12

### In plain English

Ensure separate enterprise workspaces are used on mobile end-user devices, where supported. In practice, this means you can prove you ensure end user-level controls on a defined cadence.

## Why it matters

The CIS Controls are an industry-vetted, prioritised defence: skipping a safeguard widens the attack surface that the safeguards above and below it assume is closed. Audit frameworks (FedRAMP, PCI DSS, HIPAA) all cite CIS as evidence of due care.

## What an auditor looks for

A CIS-aligned reviewer wants to see (a) which Implementation Group you are targeting, (b) a documented owner for the safeguard, and (c) a tooling or process artefact (config, scan output, ticket) that proves the safeguard runs on the cadence the control demands.

Within **Protect**, the assessor will trace your implementation back to the catalogue reference (Control 4.12) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### Cloud Posture

**CSPM.** Run Wiz / Prisma / Defender for Cloud / Security Command Center over every account; auto-ticket findings above your accepted-risk threshold.

#### Endpoint Protection

**MDM.** Make MDM enrollment a hard gate for device access (Intune compliance + Conditional Access, or Jamf + Okta device trust). Unmanaged devices simply don't get a session token.

**EDR.** Deploy CrowdStrike / SentinelOne / Defender for Endpoint to every server and laptop; alert on any host that stops sending telemetry for >24h.

#### Configuration Management

**Policy-as-code.** Codify the control as Service Control Policies (AWS), Azure Policy initiatives, or Organisation Policy (GCP) so the platform enforces what the document promises.

**IaC.** Gate Terraform / Pulumi / CloudFormation changes with Checkov / tfsec / OPA so misconfigurations never reach production.

**Drift.** Run a CSPM (Wiz / Prisma / Defender for Cloud / Security Command Center) over every account and route findings to a single risk register.

### Operational checklist

-   **Ensure.** Document the trigger, the owner and the cadence.
-   **Separate.** Document the trigger, the owner and the cadence.
-   **Protect.** Document the trigger, the owner and the cadence.
-   **Scope:** end user, mobile, network, applications, data, enterprise.

## Evidence to collect

-   **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.
-   **User Device Scan.** MDM compliance state per user device (Intune / Jamf / Workspace ONE).

Infrastructure posture tooling (AWS Config, Azure Policy, Nessus) verifies platform hardening. Endpoint compliance telemetry (Intune, Jamf) proves managed coverage. Focus: Separate Enterprise Workspaces on Mobile End-User Devices.

## Common pitfalls

-   Treating CSPM findings as a backlog instead of a hot queue: findings older than the policy SLA accumulate until the auditor asks why.
-   Pilot MDM rollouts that quietly exclude executives or engineers; carving out the highest-risk users is the most common audit failure.
-   Manual cloud-console changes that never make it back to Terraform — drift accumulates until the next outage forces a reconciliation.
-   Default-allow egress rules; East-West traffic with no segmentation; jump hosts on the public internet with password auth.

## How it maps to other frameworks

Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit.
