Final answer:
A cybersecurity analyst can effectively utilize version control to maintain a historical record of changes and ensure security in an organization's IT systems and applications by implementing version control for all documents and code, regularly assessing the impact on security, and tracking changes in network diagrams, configuration files, and code.
Therefore , the correct answer options is d)
Step-by-step explanation:
Version control is an essential tool for a cybersecurity analyst to maintain a historical record of changes and ensure security in an organization's IT systems and applications. It allows the analyst to track and manage changes to documents, code, network diagrams, configuration files, and policy updates. By utilizing version control effectively, the analyst can:
- Implement version control for all documents and code: This ensures that all changes are tracked, allowing the analyst to revert to previous versions if necessary. Reverting to a previous version can be useful in cases where security vulnerabilities or errors are introduced in the latest version.
- Regularly assess the impact on security: When reverting to a previous version or making changes, it is crucial to assess the impact on security. This involves analyzing the changes made and evaluating any potential vulnerabilities introduced.
- Track changes in network diagrams and configuration files: Network diagrams and configuration files contain important information about an organization's IT infrastructure. Using version control for these documents allows the analyst to monitor and understand the changes made, ensuring the security and integrity of the network.
- Include code changes in version control: Neglecting changes to code can pose a significant security risk. By using version control for code updates, the analyst can track and manage changes, identify potential vulnerabilities, and ensure that code remains secure.
