Implementing ISO 27001 Annex A 8.2 is the rigorous restriction of Privileged Access Rights to ensure that administrative capabilities are only granted to authorised users for specific tasks. This control mandates the technical enforcement of Multi-Factor Authentication (MFA), the separation of standard and admin accounts, and the use of Just-In-Time (JIT) access to prevent lateral movement and privilege escalation attacks.
ISO 27001 Privileged Access Rights Implementation Checklist
Use this implementation checklist to achieve compliance with ISO 27001 Annex A 8.2 by enforcing strict technical controls over administrative accounts rather than relying on paper policies. Privileged access is the primary vector for ransomware lateral movement; therefore, compliance requires granular restrictions in Active Directory, PAM solutions, and server configurations.
1. Separate Standard and Administrative Accounts
Control Requirement: Users must not use privileged accounts for day-to-day activities. Required Implementation Step: Open Active Directory Users and Computers (ADUC). Create separate accounts for IT staff (e.g., `adm-jbloggs`) specifically for administrative tasks. Enforce a technical policy that blocks their standard email/web-browsing account (`jbloggs`) from having any local admin or server rights.
Minimum Requirement: Zero users possess “Domain Admin” rights on their primary “daily driver” accounts.
2. Implement Just-In-Time (JIT) Access
Control Requirement: Privileged access rights should be restricted to the time duration necessary for the activity. Required Implementation Step: Deploy a Privileged Access Management (PAM) solution or configure Azure AD Privileged Identity Management (PIM). Configure the system so that “Standing Access” is removed; administrators must request elevation for a specific window (e.g., 4 hours), requiring a ticket number and MFA verification to activate.
Minimum Requirement: Administrators have zero rights by default and must actively “check out” privileges.
3. Hardening Service Account Permissions
Control Requirement: Non-human privileged accounts must be restricted to their specific function. Required Implementation Step: Audit all Service Accounts using `Get-ADServiceAccount`. Configure “Log on To” restrictions to limit them to specific servers. Open Local Security Policy (`secpol.msc`) on target servers and grant “Log on as a service” rights, while explicitly denying “Log on locally” and “Log on through Remote Desktop Services”.
Minimum Requirement: Service accounts are technically incapable of interactive desktop logins.
