Abstract

Identity Governance and Administration (IGA) relies on access certification to confirm that users possess only essential permissions for their assigned roles. The process supports the principle of least privilege while reducing security threats and ensuring compliance with standards like SOX, HIPAA, PCI-DSS, ISO/IEC 27001, and GDPR. Various access certification models, including manager-driven, privilege owner-driven, system owner-driven, and event-driven reviews, help organizations maintain security policies and meet compliance requirements. Challenges such as review fatigue, scalability issues, and inconsistent policies can hinder access certification effectiveness. Organizations should address these challenges through automation tools combined with risk-based prioritization, using AI-driven recommendations and ensuring integration across IT and HR systems. Optimizing certification processes enables enterprises to strengthen security measures while boosting audit preparedness and simplifying compliance management.

Introduction

Workforce identity goes through multiple stages in its lifecycle, including creation, account and access provisioning, access management, and de-provisioning¹. The most important of these is the access management phase. Most of the time, it gives assurance that the correct system users continue to hold appropriate access to systems for bona fide purposes. Access usually evolves over time due to changing business conditions, role changes, or changes in the structure of the organization. Organizations need to implement access certification to safeguard the principle of least privilege after such events.

Access certification, otherwise called access reviews, is one of the most significant and challenging processes in the IGA domain. It is the process of periodically reviewing the user’s rights over systems, applications, and data to validate them against the defined security policies, risks, and compliance with industry standards.

Terminology

Principle of Least Privilege (PoLP): The Principle of Least Privilege (PoLP) states that users, applications, and systems should be granted only the minimum level of access, permissions, or privileges necessary to perform their required tasks, nothing more. For example, a software developer may need access to a development database but shouldn't have admin rights to production systems.

Access Certification: Access Certifications, also known as access recertifications or access reviews, are the periodic process of reviewing and validating user access rights to ensure they align with business needs, security policies, and compliance requirements.

Access Recertification: A specific type of access certification that occurs at regular intervals to revalidate user access. It ensures that users still need their assigned entitlements and helps remove unnecessary or excessive access.

Privilege: Privilege in IAM refers to the rights or permissions granted to users, systems, or applications to perform specific actions. It can be standard, elevated, or administrative, depending on the level of control.

Entitlement: An entitlement is a specific set of permissions or privileges that define what a user, system, or application can access within an IT environment. It governs actions like read, write, execute, or administer resources in accordance with security policies.

Entitlement Owner: An Entitlement Owner manages and oversees specific access rights within an IAM system. They approve, review, and govern entitlements to ensure security, compliance, and least privilege access. Their role helps prevent excessive permissions and enforce access control policies.

Role-Based Access Control (RBAC): RBAC is a security model that assigns permissions to users based on their roles within an organization. Instead of granting access to individuals directly, RBAC groups users into roles, each with predefined permissions, ensuring consistent and scalable access management.

Identity Governance and Administration (IGA): Identity Governance and Administration (IGA) is a framework that manages and governs user identities, access rights, and security policies across an organization. It ensures that the right individuals have the right access to the right resources at the right time while maintaining security and compliance.

Importance of Access Certification

Access certification is necessary to ensure that users have only the access they need, minimizing security risks and maintaining compliance with industry regulations. Here are the key reasons why it is essential:

Enforcing the Principle of Least Privilege: Over time, users may accumulate unnecessary access due to role changes, retaining access to files or services they are not working on anymore, or simply by requesting and keeping access that they did not need in the first place. Certification ensures that users retain only the minimum necessary access.

Mitigating Security Risks: Unchecked access can lead to insider threats, privilege escalation, or unauthorized data exposure. Regular access reviews help prevent security breaches by identifying and revoking excessive or outdated privileges.

Compliance With Regulations: Numerous industries require adherence to regulations, making it necessary for organizations to review and certify user access routinely. These regulations are complied with through access certification.

SOX (Sarbanes-Oxley Act): An internal control system on financial reporting that includes user access control².

HIPAA (Health Insurance Portability and Accountability Act): Requires access to protect patient data from unauthorized use³.

PCI-DSS (Payment Card Industry Data Security Standard): Users with payment data systems must undergo routinely scheduled access control reviews to mitigate fraud and unauthorized payment transactions⁴.

ISO/IEC 27001: Requires periodic control of information access to meet the security objectives of the Information Security Management System (ISMS)⁵.

GDPR (General Data Protection Regulation): Organizations must restrict access to personal information and enforce measures to safeguard such data⁶.

Enhancing Audit Readiness – Organizations need to demonstrate strong access controls during audits. A well-documented access certification process provides auditors with clear evidence of compliance, reducing the likelihood of penalties.

Addressing Organizational Changes – Mergers, acquisitions, internal reorganizations, and employee role transitions often lead to shifts in access requirements. Certification helps realign access with current business needs.

Protecting Sensitive Data – By ensuring that only authorized personnel have access to critical systems and data, access certification minimizes the risk of data leaks, financial fraud, or unauthorized transactions.

Types of Access Certifications

Access certification processes can vary depending on the type of reviewers and the privileges being assessed. The most common types include:

Manager Certification: In this process, a manager reviews their team members' access to determine whether they should retain or revoke it. This method aligns with most compliance requirements and ensures employees adhere to the principle of least privilege in their daily tasks. Since managers have direct knowledge of their team members' responsibilities, they are well-positioned to evaluate whether access remains necessary.

Privilege Owner Certification: Conducted by a privilege owner (such as an entitlement or role owner), this type of review is primarily used for sensitive privileges. In some systems, entitlements or roles can be complex, making it crucial for a privilege owner, the one who oversees the structure and integrity of these permissions, to determine if a user should continue having access to a specific privilege.

System Owner Certification: This process is useful when a system or application owner has a comprehensive understanding of who requires access. System owner reviews are particularly beneficial in environments where they have insight into both the system’s privileges and the necessity of user accounts. This approach is also ideal for systems with a limited number of predefined roles or those that lack structured roles altogether.

Event-Driven Access Certification: Significant organizational changes, such as mergers, acquisitions, team restructuring, or employee role changes, necessitate a reassessment of user access. Event-driven certifications help ensure users retain only the access required for their new roles while removing unnecessary permissions. An advanced access governance system can automate the generation of these events, prompting timely reviews. A new manager is typically responsible for evaluating and adjusting user access after such transitions.

Lifecycle of Access Certification

Figure 1: Lifecycle of Access Recertification

Irrespective of the type of access certification, their lifecycle can be represented as a cyclical process involving several key stages. These stages are described below: 

Initiation – The certification process begins with identifying users, roles, and entitlements needing review. This step defines the scope, frequency, and compliance requirements.

Review & Decision – Access reviewers (such as managers, system owners, or compliance officers) assess whether users should retain, modify, or revoke access based on business needs and policies.

Remediation – If excessive or outdated access is identified, corrective actions (such as access removal or privilege adjustments) are taken to enforce the principle of least privilege.

Audit & Reporting – The review results are documented for audit purposes. Compliance teams may generate reports to demonstrate adherence to regulatory and security requirements. This reporting step is an essential aspect of the access certification process and the one that matters the most from an audit and compliance perspective. The auditors often like to check if the corrective actions were taken on time and whether proper records are in place.

Optimization – Organizations analyze certification data to identify recurring issues, improve access governance policies, and optimize future certification cycles

The process is repeated periodically (e.g., quarterly, semi-annually, annually) to ensure ongoing security and compliance.

Frequency of Access Recertification

Recertifications can be done periodically (quarterly, semi-annually, or annually), as a one-time activity, or event-driven, depending on various factors:

Compliance Requirements: SOX, PCI, HIPAA, and others require specific recertification frequencies, usually semi-annual or annual, to meet audit and compliance obligations. Align your recertification cycles with these mandates to avoid penalties and maintain a strong security posture.

Risk Associated With Access: A risk-based approach is a good way to manage recertifications at scale. High-risk or privileged access (e.g., admin accounts, financial systems) should be reviewed more often, usually quarterly. Moderate-risk access can be reviewed semi-annually, and low-risk entitlements annually to optimize without compromising security.

Event-Driven Triggers: Beyond periodic reviews, access should be re-certified when role changes, terminations, mergers, or security incidents occur. These triggers ensure entitlements are current and don’t introduce risk from outdated or excessive access.

Challenges in the Access Certification Process and How to Overcome Them

As mentioned before, access certification is a crucial process, but it comes with several challenges that organizations must address to make it efficient and effective.

1. Review Fatigue and Rubber-Stamping
Challenge:
Reviewers, including managers, privilege owners, and system owners, often encounter a high volume of access review requests, leading to fatigue and a tendency to approve access without proper validation, a practice known as "rubber-stamping."

Solution:

Risk-Based Prioritization: Rather than reviewing all access indiscriminately, organizations should focus on high-risk permissions. This approach involves scoping reviews based on data sensitivity, user roles, and access levels, ensuring that critical permissions receive the necessary scrutiny.

Automated Recommendations: Leveraging AI and machine learning algorithms can aid in identifying outlier access patterns and recommending decisions based on access trends, sensitivity levels, and other relevant factors. This approach enhances decision-making efficiency and accuracy.

2. Lack of Context for Reviewers
Challenge:
Reviewers often lack sufficient insights into users' access needs, making it difficult to assess whether access remains necessary. Decision-making can be ineffective without contextual information, such as access request history, usage frequency, or peer comparisons.

Solution:

Contextual Data Presentation: Providing key details, such as when access was requested, its intended purpose, recent usage patterns, and whether similar access exists among peers, can significantly improve review accuracy. Displaying associated risk levels further aids reviewers in making informed decisions.

Integration with HR and IT Systems: Connecting access governance solutions with HR systems enables automatic detection of user lifecycle events (e.g., role changes), triggering appropriate access reviews and ensuring timely modifications.

Role-Based Access Control (RBAC) or Policy-Based Access Control (PBAC): Implementing structured access models, such as RBAC, simplifies decision-making by associating technical entitlements with user-friendly role names (e.g., "IT Admin"). RBAC allows for enrollments via the assignment of roles (hopefully with HR integrations) and leverages group memberships. Policy-Based Access Control (PBACK) is also a popular access control model. In the PBAC scenario, access control is managed by dynamically evaluating attributes such as user department, location, or risk level against predefined policies to determine access. Having a structured approach reduces complexity for reviewers unfamiliar with granular access details.

3. Audit and Compliance Complexities

Challenge:
Maintaining detailed audit logs and proving compliance with regulatory requirements can be challenging, especially for large enterprises with multiple systems.

Solution:

Centralized Identity Governance and Administration (IGA) Platforms: Use a mature IGA solution to maintain audit trails and generate compliance reports.

Automated Logging and Reporting: Implement tools that capture all access review actions in real-time.

Regular Compliance Reviews: Schedule periodic internal audits to ensure certifications align with regulatory standards.

4. Scalability Issues in Large Organizations

Challenge:
Enterprises with thousands of employees and diverse applications struggle to scale the access certification process efficiently. 

Automation of processes can help significantly, but the extent of automation in the access certification process depends on the maturity of an enterprise's access governance and provisioning solutions. In highly automated environments where access provisioning is policy-driven, user access reviews may become unnecessary, as only the policies themselves need to be evaluated for appropriateness. Conversely, the certification process becomes significantly more manual in less mature setups where access is manually provisioned and target systems are not integrated with the access governance solution. In such cases, organizations may rely on spreadsheets and documents to track access, coordinate with reviewers, and work with system owners to revoke inappropriate access.

Solution:

Automation and AI-Powered Access Reviews: Reduce manual effort by using AI/ML to analyze access patterns and suggest approvals or revocations.

Implement Rule-Based Provisioning: Implementing automated rules for low-risk access eliminates the need for manual reviews. For instance, predefined access rules for repositories in a version control system can significantly reduce the review burden for managers.

Dynamic Access Reviews: Implement event-driven certifications triggered by job changes, project completions, or system updates.

Federated Review Approach: Break reviews into smaller segments by delegating them to multiple stakeholders.

5. Lack of Integration Across Multiple Systems
Challenge:
Organizations often manage access across various applications, cloud services, and legacy systems that may lack interoperability, complicating the certification process.

Solution:

API-Based Integration: Utilizing API-driven connectors allows seamless aggregation of access data from disparate systems into a unified governance framework.

Unified Identity Governance Platforms: Adopting modern identity governance solutions that integrate with both on-premises and cloud applications enhances visibility and control over access reviews.

6. Inconsistent or Unclear Policies
Challenge:
Organizations with poorly defined access certification policies face inconsistencies in enforcement, resulting in security vulnerabilities.

Solution:

Standardized Access Policies: Establishing clear guidelines for different access levels and defining uniform review criteria ensures consistency in certification efforts.

Policy-Based Access Management: Automating policy enforcement minimizes discrepancies and strengthens access governance.

Regular Training and Awareness Programs: Educating reviewers on their responsibilities and the importance of precise access validation enhances the overall effectiveness of the certification process.

Conclusion

Access certification enforces access governance and compliance and helps validate security best practices. For an organization to keep the identity management framework compliant and secure, an effective access certification is necessary. Even though the process is crucial in enforcing security best practices, it suffers from various issues such as rubber-stamping, blind spots, and scalability issues. Having said this, organizations need to be more effective when it comes to the review process. Automating tools, AI-based decision-making, and contextual data diagrams are some of the manually challenging aspects that organizations should adopt. In addition, certification approaches must be aligned with the policies of the organization and industry, improving overall governance. If access certification is configured correctly and optimized, security risks will be minimized and a proactive security culture will be encouraged, ensuring users gain access only to what is required.
