How can you ensure that vault firewall rules persist after changes?

Adding firewall exceptions to the dbparm.ini file and restarting the vault is the appropriate method to ensure that vault firewall rules persist after modifications. This configuration file is a pivotal part of the CyberArk architecture, as it contains parameters and settings that govern the operation of the CyberArk Vault. By including firewall exceptions in this file, you establish a permanent rule set that will automatically be recognized each time the vault service is started.

When the vault is restarted, it reads the dbparm.ini file, thereby applying the specified firewall exceptions consistently. This process ensures that any change made will not be lost or overridden by other configurations at the time of reboot, which is essential for maintaining the integrity and security of the Vault.

Other options, while they might seem viable at first glance, lack the robustness needed for persisting firewall rules effectively. For instance, manually adjusting settings in the firewall may work temporarily, but these changes could be reverted or lost due to updates or reconfigurations of the system. Using a script to reapply rules weekly also introduces potential points of failure and management overhead, as one would need to ensure the script runs successfully and is updated as needed. Changing registry settings could potentially impact other components of the system and is not a standardized method for managing firewall exceptions
