BSI C5 · Control SIM-02 · Priority: high · Component: Security Incident Management

### What this control covers

Engages experts to classify, prioritize, and analyze potential security incidents, performing root-cause analysis. Ensures swift and accurate handling to mitigate impacts on cloud customer data and maintain service security and integrity.

### Why it matters

Risk is the language an executive team understands; this control connects technical reality to board-level decisions and budget allocation.

### How to implement

#### AWS

Codify the policy intent as **SCPs, AWS Config conformance packs, and Security Hub standards** so the cloud enforces what the document says.

#### Azure

Codify in **Azure Policy initiatives** (built-in regulatory compliance for CIS, ISO 27001, SOC 2, HIPAA) and assign at management-group level.

#### GCP

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

#### Google Workspace

Enforce **2-Step Verification** (preferably hardware keys for admins) for the entire org, set session length to ≤ 12 hours, and disable less-secure-app access. Use **Context-Aware Access** levels to restrict admin sign-in by IP/device posture. Provision and de-provision users via **SCIM** from your HRIS so leavers lose access on day one.

#### GitHub

Require **SSO + SCIM** from your IdP on the organisation; enforce **2FA** org-wide and use **fine-grained PATs** (or, better, GitHub Apps) instead of classic tokens. Restrict **outside collaborators**, require signed commits on protected branches, and use **OIDC** from Actions to short-lived AWS/GCP/Azure credentials rather than stored secrets.

#### Zoho Mail

Make **two-factor authentication** mandatory for all users (TOTP, OneAuth, or YubiKey) in _Admin Console → Security_. Configure **SAML SSO** against your IdP and disable password-based logins for admins. Use **role-based privileges** (Admin / Spam Moderator / Mail Account Admin) and review the _Login history_ report monthly for anomalies.

#### On-premises

Maintain a policy library with a documented review cadence (annual minimum); store in your GRC tool with attestation tracking. Map each policy to controls so an audit pull cites the exact policy clause.

### Evidence to collect

-   `policy_document` — A signed, version-controlled policy stating leadership intent and the named owner.

Signed policy or standard documents the safeguard. Focus: Processing of security incidents.
