A company is preparing to roll out a major update to one of its critical applications. The update includes new features and security patches. Prior to deployment, the security team wants to ensure that they can quickly revert to the previous stable version in case of unexpected problems with the new release. Which method would BEST ensure that they can manage and control application versions effectively?
Deploy an automated patch management tool to handle version updates.
Implement a version control system to manage application updates and rollbacks.
Create regular manual backups of the application's installation directory.
Update the disaster recovery plan to include steps for reverting application updates.
Using a version control system is the best method for managing and controlling application versions as it allows teams to track changes, revert to previous versions, and maintain a history of modifications. This system enables quick reversion to a known good state in case the new update causes issues. Manual backups could also allow reversion but lack the history tracking and might not be as current. An automated patch management tool is more for ensuring systems are up-to-date and is not designed primarily for version tracking or quick reversion. The disaster recovery plan focuses on recovering from catastrophic events and is not typically used for routine version management.
