Quarterly User Access Review: What to Review and Who Should Approve
Introduction
A quarterly user access review is one of the most important controls organizations use to protect sensitive information, maintain regulatory compliance, and reduce the risk of unauthorized access. Whether an organization operates in banking, healthcare, government, or any highly regulated industry, regular user access reviews help ensure that employees, contractors, and third parties only have access to the systems and data necessary to perform their job functions.
While many organizations understand the importance of conducting reviews, they often struggle with two key questions:
- What should be reviewed during a quarterly user access review?
- Who should be responsible for approving access?
A well-defined user access review procedure answers both questions and helps organizations create a repeatable, auditable process that satisfies internal security requirements and regulatory expectations. This guide explains the essential elements of a successful quarterly user access review, outlines approval responsibilities, and provides an example of quarterly user access review best practices that organizations can follow.
Why Are Quarterly User Access Reviews Important
Access privileges change constantly as employees join the organization, change roles, receive promotions, transfer departments, or leave the company. Without a structured periodic user access review, organizations often accumulate excessive access rights that create unnecessary security risks.
A periodic user access review helps organizations ensure that access aligns with current business responsibilities. It also provides an opportunity to identify dormant accounts, excessive privileges, and policy violations before they become security incidents.
For organizations subject to regulations such as SOX, GLBA, FFIEC guidance, HIPAA, PCI DSS, or other compliance frameworks, documented user access reviews are often a required control. Auditors frequently expect organizations to demonstrate not only that reviews were completed, but also that inappropriate access was identified and remediated.
What Should Be Reviewed During a Quarterly User Access Review?
A comprehensive quarterly user access review should examine more than a simple list of users. Reviewers should evaluate both who has access and whether that access remains appropriate.
1. User Accounts
The first step of any review is confirming that each account belongs to a valid, active user. Reviewers should verify that employees are still employed, contractors remain engaged, and third-party users still require access to company systems.
This process often reveals accounts belonging to terminated employees, inactive contractors, or individuals whose responsibilities have changed significantly since access was originally granted. These accounts represent unnecessary risk and should be investigated immediately.
Organizations should also verify that users are assigned to the correct department and reporting structure. A user who has transferred to another area of the business may still retain access from a previous role, creating excessive privileges that violate least-privilege principles.
Inactive or former employee accounts are among the most common findings during audits and security assessments.
2. Application Access
After confirming the validity of user accounts, organizations should evaluate access within each application being reviewed. The goal is to determine whether users continue to need the permissions they currently possess.
Reviewers should consider the user’s job responsibilities and whether their access remains appropriate for their role. This review should include business-critical systems such as financial applications, core banking platforms, human resources systems, customer relationship management solutions, cloud services, and internally developed applications.
Rather than simply asking whether a user should have access, reviewers should also determine whether the level of access remains appropriate. A user may legitimately require access to an application while no longer needing administrative or elevated permissions.
3. Administrative and Privileged Access
Special attention should be given to users with elevated privileges. Administrative accounts provide broad access to systems and data, making them attractive targets for both external attackers and insider threats.
A quarterly review should carefully evaluate privileged accounts to ensure there is a documented business justification for the access. Reviewers should verify that elevated permissions remain necessary and that users have not retained administrative rights after changing roles or responsibilities.
Because privileged access presents greater risk than standard user access, many organizations apply additional scrutiny and approval requirements to these accounts during the review process.
4. Role Memberships
Many organizations manage access through application or enterprise roles rather than assigning permissions directly to individual users. As a result, reviewing the role memberships is just as important as reviewing individual user access.
A user may appear to have appropriate access when viewed individually, but their role memberships may grant additional privileges that are no longer necessary. Quarterly reviews provide an opportunity to validate that role assignments remain aligned with current job functions and organizational responsibilities.
Organizations that have implemented role-based access controls often find that access reviews become significantly more efficient because reviewers can focus on exceptions rather than evaluating every permission individually.
5. Separation of Duties (SoD) Conflicts
Many organizations use quarterly reviews to identify potential conflicts that could enable fraud or unauthorized activities.
Examples include users who can:
- Create and approve payments
- Create vendors and issue payments
- Open and approve accounts
- Modify security permissions and approve access requests
Addressing separation of duties conflicts reduces operational and compliance risk and should be highlighted during the regular user access review process.
6. Inactive and Orphaned Accounts
Inactive accounts represent one of the most common findings during audits and security assessments. These accounts often remain active because they were overlooked during employee terminations, system migrations, or organizational changes.
A quarterly review should identify accounts that have not been used for extended periods and determine whether they should remain active. Organizations should also investigate orphaned accounts—accounts that cannot be linked to an active employee, contractor, or business owner.
Removing unnecessary accounts reduces the organization’s attack surface and improves overall security posture.
Who Should Approve Quarterly User Access Reviews?
Determining the appropriate approver is just as important as determining what should be reviewed. The effectiveness of a review depends on assigning decisions to individuals who understand both the user’s responsibilities and the business purpose behind the access.
Managers and Supervisors
In many organizations, direct managers serve as the primary reviewers because they have the best understanding of employee responsibilities. Managers are typically well-positioned to determine whether an employee still requires access based on their current duties and reporting relationships.
Because managers are closest to day-to-day business operations, they can often identify inappropriate access that might otherwise go unnoticed.
Application Owners
For business-critical applications, application owners should play a central role in the approval process. Application owners understand how the system is used, what information it contains, and which types of access are necessary for different job functions.
Their involvement helps ensure that access decisions are based on business requirements rather than technical assumptions.
Many regulatory frameworks specifically expect application owners to participate in access certification processes because they are accountable for protecting the information and functionality within their systems.
Data Owners
When applications contain sensitive or regulated information, data owners may also be required to review and approve access. Their responsibility is to determine whether users have a legitimate need to access the data under their stewardship.
Data owners are particularly important when reviewing access to:
- Customer information
- Financial data
- Payroll records
- Healthcare information
- Confidential business information
Data owners can evaluate whether users require continued access to sensitive data sets.
Security and Compliance Teams
Security and compliance teams generally provide oversight rather than serving as primary approvers. Their role is to ensure that reviews are completed on time, identify potential risks, monitor policy compliance, and support audit requirements.
While security professionals possess technical expertise, they are often not in the best position to determine whether a user requires access to perform specific business functions. That decision is typically best left to managers, application owners, or data owners.
Example of Quarterly User Access Review Workflow
The following is an example of a typical quarterly user access review process. This process easily automated with tools like Access Auditor, providing significant time-savings to a very labor-intensive process.
Step 1: Collect Access Data
Gather users, groups, roles, and permissions from all in-scope systems.
Step 2: Validate User Identity
Match accounts to employees, contractors, and vendors.
Step 3: Assign Reviewers
The organization then validates account ownership and routes review tasks to the appropriate managers, application owners, or data owners.
Step 4: Review Access
Reviewers evaluate access based on current business needs and either approve continued access, request modifications, or revoke unnecessary permissions.
Step 5: Remediate Findings
Once decisions are made, remediation activities are tracked to ensure denied access is removed promptly.
Step 6: Generate Audit Evidence
The process concludes with reporting and documentation that demonstrate the review was completed and that any findings were addressed. These records become important evidence during audits and regulatory examinations.
Best Practices for a Successful Quarterly User Access Review
Organizations that achieve the greatest value from their user access review procedure typically focus on consistency, accountability, and automation. Using Access Auditor avoids all of the manual work both from the administrators managing the review, as well as the approvers performing the access review.
SCC provides a more comprehensive guide for best practices for user access reviews. The summary is:
Automate Data Collection
Manual spreadsheets increase effort and introduce errors. Access data should be collected directly from authoritative systems whenever possible to reduce manual effort and improve accuracy.
Focus on High-Risk Access
Reviews should focus on high-risk applications and privileged access while ensuring that denied permissions are actually removed. You should especially focus on:
- Administrative privileges
- Financial systems
- Customer data
- Sensitive applications
Use Role-Based Access Reviews
Reviewing access by role rather than individual entitlement simplifies decision-making and improves accuracy.
Track Remediation
Review completion alone is not enough. Organizations must verify that denied access is actually removed.
Maintain Audit Evidence
Every decision should be documented to support internal audits and regulatory examinations.
Most importantly, organizations should treat access reviews as an ongoing governance process rather than a compliance exercise. When conducted properly, quarterly reviews improve security, strengthen internal controls, and provide greater visibility into who has access to critical systems and information.
Conclusion
A successful quarterly user access review helps organizations reduce risk, improve compliance, and maintain strong access governance. The most effective reviews examine user accounts, application permissions, privileged access, group memberships, separation of duties conflicts, dormant accounts, and orphaned accounts.
Equally important is selecting the right approvers. Managers, application owners, and data owners are generally best positioned to determine whether access remains appropriate, while security and compliance teams provide oversight and governance.
Organizations that automate their user access review procedure are better prepared for audits, more resilient against insider threats, and more effective at maintaining least-privilege access across the enterprise.
People Also Ask
