"Readiness is not a policy document, a signed retainer, or a successful audit," the guide warns.
Identity and authentication access
The guide makes a simple operational claim: identity visibility is the immediate priority. Responders need investigator-level, read access to identity providers, directory services, SSO platforms, and federation layers so they can see authentication logs, MFA events, token issuance, session activity, privileged and service accounts, and recent permission changes. Without that visibility, the document says, teams "are building a timeline on guesswork" and containment decisions are made blindly.
Practical elements called out include predefined paths for urgent actions — credential resets, token invalidation, temporary restrictions — and pre-created accounts that are disabled until Day Zero. If identity access is debated or created during the incident, responders are "effectively blind to the attacker’s movement."
Cloud, SaaS, endpoint and logging access
On Day Zero, the guide argues, responders need a suite of immediate capabilities across cloud and endpoints. For cloud and SaaS: read access to accounts and subscriptions, audit logs, control plane activity, IAM/RBAC configurations, compute workloads, storage patterns, serverless functions, service accounts, and secrets management. For endpoints: investigator-level EDR access with historical telemetry, process and network visibility, and the authority to isolate hosts.
Logging retention is called out as a frequent practical failure: "Fourteen days of retention is common. Ninety days should be the minimum baseline." The guide stresses that some cloud telemetry is ephemeral and that if logs are not captured quickly they may be gone permanently — making immediate access to SIEM, firewall, VPN, email, and cloud audit trails essential.
Communication under breach conditions
The guide warns organizations to assume normal channels may be compromised. Email, chat, and internal collaboration tools "may no longer be private," so sensitive response planning should not be carried out there. Instead, the document requires an out-of-band communication channel that is independent of corporate identity and the production network, includes internal responders and the external retainer, supports secure sharing, and has been tested in advance.
It also prescribes a single incident manager to coordinate security, IT, legal, leadership, and external responders — a designated point of coordination who maintains scope, controls information flow, and serves as the primary interface to the IR firm. Notification paths and who gets what information, when, and by whom must be defined ahead of time to avoid debates during an incident.
Pre-approved IR access policy, accounts, and governance
A concrete policy is required, not a placeholder. The guide rejects vague language such as "responders will be granted appropriate access upon incident declaration" and says an IR policy should specify:
- Who can declare an incident and trigger emergency procedures (a CISO, security leader, or designated on-call authority).
- Who can approve temporary access for external responders without reopening procurement or legal review.
- Scope of access by responder role, time-boxed access with clear revocation, and responsibility for removing access after stabilization.
- Post-incident cleanup, access validation, and governance review.
The guide emphasizes that dormant IR accounts should exist across identity, EDR, SIEM, and cloud tenants, be disabled by default, and have a documented and tested enable procedure with MFA enrollment already completed. Background checks and legal approvals, it says, must be handled during retainer setup — not argued during a live breach.
What this means for technologists, procurement leaders, and legal teams
- Technologists and security teams: validate that investigator roles exist in EDR and SIEM, confirm 90 days of retention for key logs, create and test dormant IR accounts, and practice enabling them under pressure.
- Procurement and incident managers: ensure the retainer includes pre-approved access scopes, current contact information for the IR firm, and an out-of-band communication channel that is tested end-to-end.
- Legal and compliance teams: resolve background checks and data-access approvals during onboarding so those requirements do not become live blockers on Day Zero.
Readiness, the guide concludes, is the mundane work done before trouble arrives: accounts created, permissions mapped, MFA enrolled, workflows practiced, and a single incident manager identified. If any of the checklist questions — from enabling a dormant IR account within 30 minutes to providing 30 days of EDR telemetry or 90 days of SIEM retention — cause hesitation, the document warns, "that area is not ready." In the critical first hours, delay is not academic; it is the time attackers use to extend their foothold.
