A cloud administrator must ensure the maintenance of cloud infrastructure components. What is the BEST strategy for applying firmware upgrades to critical devices to minimize vulnerabilities?
Wait for a certain number of upgrades to accumulate before applying.
Apply upgrades immediately as they become available.
Avoid applying upgrades unless a device experiences issues.
Perform manual upgrades on a case-by-case basis.
Schedule upgrades during planned maintenance windows.
Scheduled updates ensure that firmware upgrades are applied during planned maintenance windows, reducing the impact on service availability and providing the opportunity to test new firmware in a controlled environment before broader deployment. This strategy helps in maintaining the balance between security and availability. Immediate upgrades, despite appearing proactive, might disrupt services and disregard testing protocols. Waiting for a certain number of upgrades before applying them allows vulnerabilities to exist for longer, which increases risk. Forgoing upgrades is not a viable option as it leads to outdated firmware and ignored security vulnerabilities. Manual upgrades are not efficient or scalable.
