Section: INCIDENT MANAGEMENT AND RESPONSE
Explanation:
Preparedness tests would involve simulation of the entire test in phases and help the team better understand and prepare for the actual test scenario. Options B, C and D are not cost-effective ways to establish plan effectiveness. Paper tests in a walk-through do not include simulation and so there is less learning and it is difficult to obtain evidence that the team has understood the test plan. Option D is not recommended in most cases. Option C would require an approval from management is not easy or practical to test in most scenarios and may itself trigger a disaster.

Section: INFORMATION SECURITY PROGRAM DEVELOPMENT

Explanation
Until signature files can be updated, incoming e-mail containing picture file attachments should be blocked.
Quarantining picture files already stored on file servers is not effective since these files must be intercepted before they are opened. Quarantine of all mail servers or blocking all incoming mail is unnecessary overkill since only those e-mails containing attached picture files are in question.

Information security policy enforcement is the responsibility of the chief information security officer (CISO), first and foremost. The board of directors and executive management should ensure that a security policy is in line with corporate objectives. The chief information officer (CIO) and the chief compliance officer (CCO) are involved in the enforcement of the policy but are not directly responsible for it.
