It can help reduce the risk of unauthorized software and potential security breaches, support incident response planning, and aid compliance and risk management efforts. By following industry-standard best practices, such as the CIS Critical Security Controls Version 8, organizations can ensure that software inventory procedures are implemented effectively and continuously monitored through ongoing assessment and continuous monitoring.

Best Practices for Software Inventory

Keeping an accurate and up-to-date software inventory is one of the most important steps to protect your organization from security breaches and cyber threats. The following are best practices for software inventory based on CIS CSC version 8 and industry-standard safeguards:

1. Conduct a detailed inventory: Identify all your software applications, versions, and supporting systems. This information should be organized in a way that is easy to access and understand and can be updated regularly.

2. Implement controls for unmanaged software: Unauthorized software poses a significant risk to your organization’s security. Ensure you have controls to prevent employees from installing unapproved software without your knowledge.

3. Take continuous inventory: Your software inventory should be ongoing. Regular checks ensure that all new software and changes to your existing software are recorded and tracked.

4. Establish access controls: Make sure that software applications are accessible only to individuals with a business need. This will help you minimize risks associated with uncontrolled access to software.

5. Secure service accounts: Service accounts have elevated privileges and access to your organization’s assets. Ensuring these accounts are managed and controlled to minimize potential risks is essential.

6. Maintain audit logs: Enable audit trails to track changes to your software inventory. Audit logs should be stored securely and only accessible to authorized personnel.

7. Conduct risk assessments: Regular risk assessments can help you identify vulnerabilities in your software inventory. This information can then be used to minimize risks and strengthen your security posture.

By following these best practices, you can ensure that you keep your software inventory up-to-date and secure. It is essential in preventing cyber threats and protecting your organization’s assets.
