AUTH-17 Company Restricted Systems Access Reviews

As technology continues to advance, it becomes increasingly important to maintain strict control over access to sensitive information. In order to maintain the security and integrity of company systems, it is essential to implement a robust access control process. One crucial aspect of this process is conducting regular access reviews. These reviews involve evaluating the permissions and privileges granted to individuals within the organization and ensuring that they align with their job roles and responsibilities.

This control helps in preventing data breaches, unauthorized modifications, and other security incidents that may compromise sensitive information. It also helps in ensuring compliance with regulatory requirements and industry best practices. In this article, we will explore the importance of AUTH-17 Company Restricted Systems Access Reviews control and how it can help safeguard your organization’s digital assets.

What is AUTH-17 company restricted systems access reviews control?

Company Restricted Systems Access Reviews are a way to periodically check and verify that users have the correct level of access to systems, applications, and data based on their job functions and responsibilities. The purpose of this review is to identify any unauthorized access, unnecessary access, or segregation of duties conflicts and then take corrective action to mitigate any risks.

The user access reviews involve managers or supervisors reviewing and certifying the access rights of their direct reports. This process ensures that only authorized personnel have access to the organizational resources, helping to prevent data breaches, unauthorized access, and compliance violations. It also helps to keep track of changes in the organization’s structure, such as employees leaving or changing roles, to ensure that access rights are revoked or modified accordingly.

Overall, user access reviews play a critical role in maintaining the security of an organization’s systems and data, ensuring compliance with regulatory requirements, and managing the risk associated with unauthorized access.

Ideally, this control should be performed frequently, especially for organizations that experience a lot of change. The frequency can be determined based on the criticality of the system under review. A critical or sensitive system hosting a lot of sensitive information needs to be reviewed frequently, whereas a low-risk system can be reviewed less frequently but at least annually. The decision is up to each organization.

At TrustCloud, we made it easier for organizations to make this decision by grouping sensitive systems together and less critical systems together. Each organization can then choose the frequency according to the group.

The controls referred to here are:

1. AUTH-16: This is for critical systems; this group should have their review done frequently (i.e., weekly, monthly, or quarterly) depending on the volume of activity.
2. AUTH-17: This is for less sensitive systems; this group should also have their review done frequently (i.e., monthly or quarterly) depending on the volume of activity.
3. AUTH-18: This is for low-risk systems; this group should also have their review done at least annually, depending on the volume of activity.

The importance of implementing AUTH-17 Company Restricted Systems Access Reviews control

Implementing AUTH-17 Company Restricted Systems Access Reviews is critical for maintaining the integrity and security of an organization’s data infrastructure. These reviews serve as fundamental components of a comprehensive cybersecurity strategy, ensuring that access to sensitive systems and information is restricted to authorized personnel only. By regularly evaluating who has access to restricted systems, companies can mitigate the risk of unauthorized access, thereby protecting against potential data breaches and other cyber threats.

Moreover, conducting these reviews helps identify outdated or unnecessary access privileges, which can often be overlooked but pose significant security risks. This proactive approach not only enhances data security but also ensures compliance with regulatory requirements, safeguarding the company from potential legal repercussions.

In addition to security benefits, implementing AUTH-17 Company Restricted Systems Access Reviews also promotes operational efficiency. Regular audits of system access can reveal inefficiencies and gaps in the current access control mechanisms, providing opportunities for improvements. This can lead to more streamlined processes and better resource management.

Furthermore, these reviews foster a culture of accountability within the organization. Employees become more aware of their roles and responsibilities concerning data security, which reinforces a collective commitment to safeguarding company assets. Ultimately, the consistent application of AUTH-17 Company Restricted Systems Access Reviews helps build a robust security framework that supports the organization’s long-term goals and sustainability in an increasingly digital landscape. Adopting such stringent access review protocols also plays a crucial role in risk management.

Understanding who has access to what information allows companies to anticipate potential vulnerabilities and address them proactively. This anticipatory stance is invaluable in today’s fast-paced business environment, where cyber threats are continually evolving. Therefore, the importance of implementing AUTH-17 Company Restricted Systems Access Reviews cannot be overstated; it is an essential practice that fortifies both the security and operational resilience of an organization.

Control implementation

To implement this control,

1. Define the review process and what it entails. At a minimum, it should include the following steps:
   1. Define the scope. Identify the systems, applications, and data that need to be included in the access review. Determine the frequency of the review, such as quarterly or annually.
   2. Identify the reviewers. Select the individuals who will review and certify the access rights of the users. Typically, this involves the system administrator, managers, or supervisors who are responsible for their team’s access rights.
   3. Gather information: Collect information about the users’ access rights to the identified systems, applications, and data. This may involve running reports or using automated tools to capture the user’s access details.
   4. Review access rights: Review the user’s access rights to ensure they are appropriate, necessary, and comply with the organization’s policies and regulations. This includes verifying that access rights are aligned with the user’s job function and responsibilities.
   5. Remediation: If any access rights are found to be unnecessary or inappropriate, take corrective action to remove or modify access rights. This may involve updating user roles or revoking access to specific systems or applications. You may need to provide proof of remediation for an audit. Whether this is in a ticketing system or document, be ready to provide it.
   6. Certification: The reviewers must certify that the users’ access rights have been reviewed and verified. This certification process ensures that the organization has taken reasonable measures to manage access rights and reduce the risk of unauthorized access.
   7. Documentation: Document the access review process, including the scope, findings, and remediation actions. This documentation provides evidence of the organization’s efforts to manage access rights and comply with regulatory requirements.
2. Document the review process and frequency in a policy. This can be within an existing policy (i.e., the Information Security Policy) or in a new policy.
3. Perform the review as outlined in a policy and retain documentation.

What evidence do auditors look for?

Most auditors, at a minimum, are looking for documentation that is documented within a ticketing system, along with:

1. Provide documentation that is documented within a ticketing system, along with:
   1. The user access listing was reviewed.
   2. The remediation proof, if there were any
   3. The certification from the reviewer

Evidence example

From the suggested action above, an example is provided below.

1. Provide documentation that is documented within a ticketing system, along with:
   1. The user access listing was reviewed.
   2. The remediation proof, if there were any
   3. The certification from the reviewer
      The following screenshot shows a user request ticket showing the time period during which the review was done for a number of systems for the same assignee.
      
      The following screenshot shows a ticket showing that for each system in review, a separate ticket was created that contained the user listing, the remediation if any, and the certification.
      
      The following screenshot shows an individual ticket containing, in the attachment, the user listing and the certification in the description.

NOTE: This is just an example of documentation. The certification can be done in many ways (i.e., the user list can be exported to Excel, with certification and remediation happening there).
