11 Essential Security Considerations for Change Management

In today’s business climate, our day-to-day activities almost always involve technology. Most of the world’s operations have become digitized, because of continuous technological advancements. Advancements in technology ultimately result in businesses and institutions becoming more productive either through end-user enablement or the simplification of processes thanks to the information technology we rely on. Information technology is essential because it involves storing, retrieving, transmitting and manipulating information or data. 

However, technology requires a lot of upgrading and advancement to enhance efficiency; hence, change is an important aspect to consider. Change management is a practice used to ensure various platforms help people enhance organizational changes. And with these changes, a well-modified and secure change management process is essential.

Security Considerations for Change Management

Change management is a critical process for ensuring that modifications to systems, networks, or applications are executed in a controlled and secure manner. However, there are a number security implications that must be considered to ensure that the security posture of the service is not compromised and continues to meet the business objectives and user needs. This blog will outline 11 security recommendations that companies should bear in mind when creating a change management process:

1. Establish a Formal Change Management Process

The first security recommendation that businesses should consider when it comes to change management is to formalize their change management process with documented, clearly defined procedures. This includes documenting the steps, roles, and responsibilities involved in every part of the change management process. Additionally, an approval workflow should be established to ensure that all changes are approved by relevant stakeholders before implementation, including business, security, and IT leadership.

2. Risk Assessment and Impact Analysis

Another important recommendation for change management security is to conduct regular security risk evaluations and impact analysis on each change before it is made, particularly for high-impact changes to critical systems. These assessments allow you to understand the technical and operational consequences of the proposed change, as well as any potential security risks before going ahead with the change implementation.

3. Enforce Segregation of Duties (SoD)

Segregation of Duties means separating the task of requesting changes, approving changes, and implementing changes in order to prevent conflicts of interest or insider threats. This means that the individual requesting changes should not be the one who approves or implements it. Approval should typically come from someone in a management role, who has the authority to evaluate necessity, security risks, and business impact of the change. Lastly, the individual who implements the changes should be a different person from the one who requested or approved the change. This ensures that changes go through multiple layers of scrutiny to detect any mistakes or malicious actions early.  

4. Use of Version Control and Change Tracking

Version control and change tracking is another security recommendation for change management. Tracking what changes were made, when, by whom, and why can allow for better analysis and forensics in the case of a change-related security issue. Moreover, version control also enables easier rollback procedures in the case a change needs to be reversed. 

5. Automated Change Auditing and Monitoring

Similarly to change tracking, automated logging and change monitoring can track changes made in the system for better forensics in a security-breach scenario. These logs must be stored securely and reviewed regularly. Additionally, change monitoring can detect unauthorized or unplanned changes to prevent potential security disasters in real time. 

6. Change Testing and Validation

Another important security consideration for change management is change testing and validation. Before implementing changes, organizations should require that all changes be tested in a staging environment with a security validation to ensure that the change does not introduce any new vulnerabilities or security risks. Testing these changes in a stage environment can prevent potentially devastating outcomes, like the Crowdstrike/Microsoft outage. 

7. Implement Role-Based Access Control (RBAC)

Access management is a security recommendation across all aspects of IT security, and it also applies to change management. Role-based access control limits who is able to make changes to production systems to further reduce insider threats or accidental changes. Only authorized personnel should be able to make changes with the proper approval.

8. Regular Reviews and Audits

Regular reviews and audits is a general security recommendation for all IT processes, including change management processes. These audits of the change management process help to ensure compliance with policies and detect any deviations. Security teams should also regularly review and assess the security aspects of changes, including configurations and software updates. Routine reviews can help security teams detect anomalies or potential security risks within IT systems. 

9. Training and Awareness

Proper training and security awareness can help employees understand the security implications at every stage of the change management process. All staff should be trained on the change management process and understand their roles and responsibilities, especially from a security perspective. By encouraging a culture of security awareness, organizations can significantly enhance their defense against cyber threats

10. Third-Party and Vendor Management

Many companies implement third-party software or vendors into their IT systems, which can introduce new threats to an organization. This is why, a key security consideration for change management security is to ensure that third parties and vendors also follow your organization’s change management processes or have equivalent controls. Monitoring the access given to third parties during the change process is also imperative to prevent possible security risks.
