Which of the following practices will not help the incident responders during eradication of cloud security incidents?

The practice of not using a privilege separation scheme can hinder incident responders during the eradication of cloud security incidents because privilege separation is crucial for minimizing risks associated with user access and command execution. When the principle of least privilege is followed, users are granted only the access necessary to perform their tasks, which reduces the overall attack surface. This isolation helps in containing any potential damage and facilitates a more effective incident response strategy.

In contrast, the other options promote methods that support the incident response process. Using privilege escalation judiciously allows responders to gain temporary elevated access that may be needed during a response without compromising security overall. Implementing thorough data backups ensures that critical information can be restored in the case of data loss, which is vital for recovery efforts. Additionally, performing regular system scans helps in early detection of vulnerabilities and malicious activities, aiding in proactive security measures.

Thus, opting out of a privilege separation scheme would be detrimental to incident responders, making it difficult to efficiently manage and eradicate incidents in cloud environments.
