Access Control and Identity Management Policy

Version: 1.0 | Last updated: [Date] | Document owner: [Role, e.g., CISO/IT]

1. Purpose

To establish the requirements for controlling access to [Company Name]'s systems, applications, and data, ensuring access is granted only to authorized individuals, to the extent necessary for their roles.

2. Scope

Applies to all employees, contractors, and systems accessing [Company Name]'s IT resources, including cloud environments, internal applications, and third-party tools.

3. Principle of Least Privilege

Access to any system or data must be granted based on the actual needs of the role (least privilege), never by default or convenience. Administrative-privileged accounts must be used only when strictly necessary.

4. Authentication

• Multi-factor authentication (MFA) is mandatory for all systems storing confidential or restricted data, and for all administrative access, without exception.
• Passwords must meet minimum complexity requirements and must not be reused across systems.
• Service accounts (non-human) must use credentials managed by a secrets vault, never hardcoded fixed passwords.

5. Provisioning and Deprovisioning

• System access must be formally requested and approved before being granted, with a record of who approved it and why.
• Access must be revoked within [timeframe, e.g., 24 hours] of an employee's departure or the end of a contractor's engagement.
• Role changes must trigger an access review, removing permissions no longer needed.

6. Periodic Access Review

Access reviews must be conducted [frequency, e.g., quarterly] for critical systems and [e.g., semi-annually] for others, with each area's manager validating whether their team's access remains necessary.

7. Privileged Accounts

Accounts with administrative/root access must be: individually named (never shared), protected by mandatory MFA, monitored with a log of all actions, and used via temporary privilege elevation whenever possible.

8. Roles and Responsibilities

• [Role, e.g., IT/IAM]: administers the access provisioning and deprovisioning process.
• Area managers: approve access requests for their team and participate in periodic reviews.
• [Role, e.g., CISO]: audits the effectiveness of access controls and approves exceptions.

9. Non-Compliance

Use of shared credentials, granting access outside the formal process, or maintaining unnecessary access constitute a violation of this policy and must be reported and corrected immediately.

10. Policy Review

Annual review, or after a security incident involving access control.
