1. Purpose

The Privileged Access Register maintains a centralized record of users, accounts, roles, and systems with elevated or administrative access.

It helps the organization:

• Identify all privileged users.
• Understand why privileged access is required.
• Apply least privilege.
• Track approvals.
• Monitor high-risk access.
• Conduct periodic privileged-access reviews.
• Control temporary and emergency access.
• Remove unnecessary privileges.
• Provide audit evidence.

Core Principle

Identify → Justify → Approve → Grant → Monitor → Review → Revoke

---

2. What Is Privileged Access?

Privileged access is access that allows a user or account to perform administrative, security-sensitive, configuration, or high-impact activities.

Examples include:

• AWS Administrator
• Cloud account administrator
• IAM administrator
• Database administrator
• Domain administrator
• Identity administrator
• Security administrator
• Production administrator
• Firewall administrator
• Source-code repository administrator
• Backup administrator
• Encryption/key administrator

Privileged access should be determined based on the actual capabilities of the role, not simply the job title.

---

7. Privileged Account Details

For each privileged account, record:

• Account name
• Account owner
• System
• Privileged role
• Account type
• Authentication method
• MFA status
• Business purpose
• Approval
• Review frequency
• Expiry date where applicable

Account Type

Use one of:

• Standard User Account
• Separate Privileged Account
• Break-Glass Account
• Service Account
• Emergency Account
• Third-Party Account

---

8. Named Privileged Accounts

Where practical, privileged activities should be performed using individually assigned accounts.

Example

Instead of:

admin@company.com

being used by multiple administrators, use individually attributable accounts such as:

• satyendra.admin
• rahul.admin
• neha.admin

This improves accountability and auditability.

Shared privileged accounts should be avoided where individual accounts are technically and operationally feasible.

---

9. Business Justification

Every privileged access record should have a documented business reason.

Example

“DevOps Lead requires administrative access to the production AWS environment to manage approved infrastructure changes, deployments, and incident response activities.”

Avoid vague justifications such as:

“Required for work.”

The justification should explain:

What privileged activity is required + Why it is required + Which system is affected.

---

10. Least Privilege Assessment

Before granting privileged access, determine whether full administrator access is actually required.

Ask:

• Does the user need administrator access?
• Can a predefined lower-privilege role satisfy the requirement?
• Does the user need production access?
• Does the user need write access?
• Does the user need delete permissions?
• Does the user need security configuration access?
• Does the user need access to all resources?
• Can access be limited to a specific project/account/resource?
• Can access be temporary?

Example

Instead of:

AWS AdministratorAccess

consider:

SecurityAudit

or another narrowly scoped IAM role where it meets the business requirement.

---

11. AWS Privileged Access Register

For AWS environments, capture additional information.

Field	Example
AWS Account	Production
Account ID	[Account ID]
IAM Identity	User/SSO Identity
IAM Role	ProductionAdmin
Permission Level	Administrator
Resource Scope	Production
MFA	Enabled
SSO	Enabled
CloudTrail	Enabled
Business Owner	CTO
Access Owner	DevOps Lead
Review	Quarterly
Status	Active

AWS Privileged Roles

Examples:

• Organization Administrator
• IAM Administrator
• Security Administrator
• Production Administrator
• Database Administrator
• Billing Administrator
• Network Administrator

The actual permissions should be reviewed rather than relying only on the role name.

---

12. Production Privileged Access

Production privileged access should receive additional scrutiny.

Check:

• Business justification exists
• System owner approval exists
• Security approval where required
• MFA enabled
• Individual identity used
• Activity logged
• Monitoring enabled
• Permissions minimized
• Access review scheduled
• Temporary access has expiry where appropriate

---

13. Privileged Access Approval

Request

• User:
• System:
• Privileged Role:
• Business Purpose:
• Required Start Date:
• Required End Date:
• Data/Resources:
• Risk:

Approval

Manager/Business Owner

• Name:
• Approval:
• Date:

System Owner

• Name:
• Approval:
• Date:

Security/ISMS

• Name:
• Approval:
• Date:

Additional approval may be required depending on organizational risk.

---

14. Temporary Privileged Access

Temporary privileged access should be used where permanent privilege is unnecessary.

User	System	Privilege	Purpose	Start	Expiry	Approver	Status
Consultant	AWS	Security Read	VAPT	01-Oct	05-Oct	CTO	Active
Developer	Production	Log Read	Incident	10-Oct	11-Oct	Security	Closed

Temporary access should automatically expire where technically possible.

---

15. Emergency / Break-Glass Access

Emergency accounts may be required for critical situations.

Examples:

• Identity-provider failure
• Major production outage
• Security incident
• Emergency vulnerability remediation

Controls should include:

• Restricted ownership
• Strong authentication
• Secure credential storage
• Limited use
• Logging
• Monitoring where possible
• Post-use review
• Credential rotation where appropriate

Emergency Flow

Emergency → Authorize → Access → Log → Resolve → Review → Revoke/Rotate

---

16. Privileged Service Accounts

Service accounts may have elevated permissions without being associated with a human user.

Record:

• Service account name
• System
• Owner
• Business purpose
• Application/service
• Permissions
• Credentials location
• Secret-management mechanism
• Rotation requirement
• Interactive login status
• Monitoring
• Review date
• Status

Important

A service account should have an accountable human/system owner.

---

17. Privileged Access to Secrets

Privileged users may have access to:

• Passwords
• API keys
• SSH keys
• Encryption keys
• Cloud credentials
• Certificates
• Production secrets

Check:

• Secrets are stored in an approved secrets-management system
• Access is restricted
• MFA is used where applicable
• Access is logged where supported
• Secret exposure is prevented
• Rotation is defined
• Access is periodically reviewed

---

18. Privileged Access Monitoring

Where technically appropriate, monitor:

• Login events
• Privilege elevation
• Administrative actions
• Configuration changes
• User creation/deletion
• Permission changes
• Security-policy changes
• Production changes
• Database administrative activity
• Cloud administrative actions

Example

AWS administrative activity can be monitored through appropriate AWS logging and monitoring services, including CloudTrail.

---

19. Privileged Access Review

Review the register periodically.

For each privileged user:

• User still exists
• User still has the same role
• Business need still exists
• Privileged role is still required
• Permissions remain appropriate
• MFA remains enabled
• Logging remains enabled
• Temporary access has expired where applicable
• Third-party engagement remains active
• Service account owner remains valid
• No unnecessary privilege exists

---

20. Privileged Access Review Record

ID	User	System	Current Privilege	Required?	Action	Owner	Date	Status
PR-001	User A	AWS	Administrator	Yes	Retain	CTO	Date	Closed
PR-002	User B	GitHub	Admin	No	Reduce	Engineering	Date	Closed
PR-003	Contractor	AWS	Admin	No	Revoke	CTO	Date	Closed

---

21. Privilege Reduction

When excessive privilege is identified:

Identify → Confirm → Approve → Reduce → Verify → Record

Example:

A developer has:

AWS Administrator

but requires only:

Production Log Read

The administrator permission should be reduced to the approved role, subject to the organization’s access model.

---

22. Privileged Access Revocation

Privileged access should be revoked when:

• Employee leaves
• Contractor engagement ends
• User changes role
• Project ends
• Temporary access expires
• Business need ends
• Privilege is no longer justified
• Security incident requires immediate restriction

Review:

• Cloud roles
• IAM permissions
• Database privileges
• SaaS administration
• Source-code administration
• API keys
• SSH keys
• Tokens
• Certificates
• VPN access
• Physical administrative access

---

23. Privileged Access Exception Register

Where the standard control cannot be applied:

Exception ID	System	User	Exception	Reason	Risk	Compensating Control	Approver	Expiry	Status
PAE-001	Production DB	DBA	Shared emergency account	Legacy system	High	Vault + logging	CTO	Date	Active

Exceptions should be reviewed and closed when the underlying reason no longer exists.

---

24. Privileged Access Incident

Privileged accounts should be treated as high-risk during security incidents.

Examples:

• Suspected administrator credential compromise
• Unauthorized privilege escalation
• Unexpected admin login
• Unapproved production change
• Stolen privileged device
• Exposed cloud credential

Potential actions include:

Disable → Revoke Sessions → Rotate Credentials → Investigate → Preserve Evidence → Assess Impact → Remediate → Review

Follow the organization’s Incident Response and Access Revocation procedures.

---

25. Privileged Access Metrics

Useful metrics include:

Metric	Example
Total privileged users	12
Privileged accounts	15
Privileged service accounts	4
Privileged third parties	2
Privileged accounts with MFA	100%
Temporary privileged accounts	3
Expired privileged accounts	1
Excess privileges identified	2
Privileged access findings closed	2
Overdue reviews	0

Metrics should be used to identify control weaknesses and improvement opportunities rather than simply to demonstrate a target percentage.

---

26. Evidence

Maintain appropriate evidence such as:

• Privileged Access Register
• Access requests
• Approval records
• IAM role configuration
• SSO assignments
• MFA configuration
• Privileged access review records
• Access logs
• CloudTrail records
• Database privileged-user lists
• Security-platform administrator lists
• Temporary access records
• Emergency access records
• Access revocation evidence
• Exception records
• Remediation evidence

---

27. Common Mistakes

❌ Everyone receives administrator access

Administrative access should be limited to legitimate requirements.

❌ Privileged access is based only on job title

A CTO or developer may require different permissions depending on actual responsibilities.

❌ Shared administrator accounts

These reduce individual accountability.

❌ No expiry for temporary privilege

Temporary privilege should have an appropriate expiry.

❌ No periodic review

Privileged access should be reviewed based on risk.

❌ Privileged access is not logged

High-risk administrative activity should be traceable where technically feasible.

❌ Former employees retain privileged access

Offboarding must include privileged-access revocation.

31. ISO 27001 Connection

The Privileged Access Register supports applicable ISO/IEC 27001 requirements relating to:

• Access rights
• Identity management
• Authentication
• Privileged access
• Restriction of access to information
• Segregation of duties
• Logging and monitoring
• Access review
• Secure user lifecycle management

The exact controls applicable to the organization should be determined through its risk assessment and Statement of Applicability (SoA).

32. Final Audit Trail

An auditor should be able to trace:

Who has privileged access?

↓

Which system can they administer?

↓

What exact privilege do they have?

↓

Why is the privilege required?

↓

Who approved it?

↓

Is MFA and appropriate monitoring enabled?

↓

Was the access periodically reviewed?

↓

Was unnecessary privilege removed?

↓

Was access revoked when no longer required?

Final Principle

Privileged access should be rare, justified, individually attributable, appropriately protected, monitored where practical, periodically reviewed, and removed when the business need ends.
