A company's IT team detects an anomaly in a cloud environment after a software update. What should be their first action?

• A. Notify customers of a potential breach
• B. Perform a full system check
• C. Isolate the affected systems and perform a rollback
• D. Update security protocols immediately

Answer: (C)

The most appropriate first action after detecting an anomaly in a cloud environment following a software update is to isolate the affected systems and perform a rollback. This approach is crucial for several reasons. Isolating the affected systems helps contain any potential damage that could be caused by the anomaly. By removing the at-risk systems from the network, the team can prevent the problem from spreading and potentially affecting other systems or services. This containment is a fundamental step in incident response, prioritizing the preservation of the overall system integrity and security. Performing a rollback to the previous stable state allows the organization to revert to an environment that is known to be secure and functional. This minimizes downtime and disruptions in operations while allowing the IT team to analyze the anomaly without the pressure of an immediate impact on services. In contrast, notifying customers of a potential breach may be premature at this stage, as the nature and extent of the anomaly need to be assessed first. A full system check, while important, may be better implemented after initial containment actions, as resources should be focused on addressing the potential risk immediately. Lastly, updating security protocols is certainly necessary as a follow-up action, but it is essential to first stabilize the systems before making changes to security measures that could affect system functionality.
