Section: INFORMATION SECURITY GOVERNANCE
Explanation:
Developing a strategy paper on information security would be the most appropriate. Approving access would be the job of the data owner. Updating platform-level security and conducting recovery test exercises would be less essential since these are administrative tasks.

Section: INFORMATION SECURITY PROGRAM MANAGEMENT
Explanation

Section: INFORMATION RISK MANAGEMENT

Risks are constantly changing. A previously conducted risk assessment may not include measured risks that have been introduced since the last assessment. Although an assessment can never be perfect and invariably contains some errors, this is not the most important reason for periodic reassessment. The fact that controls can be made more efficient to reduce costs is not sufficient. Finally, risk assessments should not be performed merely to justify the existence of the security function.

Section: INCIDENT MANAGEMENT AND RESPONSE
Explanation
Explanation:
Isolating the server will prevent further intrusions and protect evidence of intrusion activities left in memory and on the hard drive. Some intrusion activities left in virtual memory may be lost if the system is shut down.
Duplicating the hard disk will only preserve the evidence on the hard disk, not the evidence in virtual memory, and will not prevent further unauthorized access attempts. Copying the database log file to a protected server will not provide sufficient evidence should the organization choose to pursue legal recourse.
