The Recovery Point Objective (RPO) describes the acceptable amount of data loss measured in time. It is the point in time to which data must

be recovered as defined by the organization. The RPO is generally a definition of what an organization determines is an 'acceptable loss' in a

disaster situation. If the RPO of a company is 2 hours and the time it takes to get the data back into production is 5 hours, the RPO is still 2

hours. Based on this RPO the data must be restored to within 2 hours of the disaster.

Answer B is incorrect. The Recovery Time Objective (RTO) is the duration of time and a service level within which a business process

must be restored after a disaster or disruption in order to avoid unacceptable consequences associated with a break in business continuity. It

includes the time for trying to fix the problem without a recovery, the recovery itself, tests and the communication to the users. Decision time

for user representative is not included. The business continuity timeline usually runs parallel with an incident management timeline and may

start at the same, or different, points.

In accepted business continuity planning methodology, the RTO is established during the Business Impact Analysis (BIA) by the owner of a

process (usually in conjunction with the Business Continuity planner). The RTOs are then presented to senior management for acceptance.

The RTO attaches to the business process and not the resources required to support the process.

Answer D is incorrect. The Recovery Time Actual (RTA) is established during an exercise, actual event, or predetermined based on

recovery methodology the technology support team develops. This is the time frame the technology support takes to deliver the recovered

infrastructure to the business.

Answer C is incorrect. The Recovery Consistency Objective (RCO) is used in Business Continuity Planning in addition to Recovery Point

Objective (RPO) and Recovery Time Objective (RTO). It applies data consistency objectives to Continuous Data Protection services.

The security challenges for DRM are as follows:

Key hiding: It prevents tampering attacks that target the secret keys. In the key hiding process, secret keys are used for

authentication, encryption, and node-locking.

Device fingerprinting: It prevents fraud and provides secure authentication. Device fingerprinting includes the summary of hardware

and software characteristics in order to uniquely identify a device.

OTA provisioning: It provides end-to-end encryption or other secure ways for delivery of copyrighted software to mobile devices.

Answer B is incorrect. Access control is not a security challenge for DRM.

Confidentiality is a term that refers to the protection of data against unauthorized access. Administrators can provide confidentiality by

encrypting data. Symmetric encryption is a relatively fast encryption method. Hence, this method of encryption is best suited for encrypting

large amounts of data such as files on a computer.

Answer A is incorrect. Integrity ensures that no intentional or unintentional unauthorized modification is made to data.

Answer C is incorrect. Auditing is used to track user accounts for file and object access, logon attempts, system shutdown etc. This

enhances the security of the network. Before enabling auditing, the type of event to be audited should be specified in the Audit Policy in User

Manager for Domains.

The owner of information delegates the responsibility of protecting that information to a custodian. The following are the responsibilities of a

custodian with regard to data in an information classification program:

Running regular backups and routinely testing the validity of the backup data

Performing data restoration from the backups when necessary

Controlling access, adding and removing privileges for individual users

Answer C is incorrect. Determining what level of classification the information requires is the responsibility of the owner.

DITSCAP stands for DoD Information Technology Security Certification and Accreditation Process. The DoD Directive 5200.40 (DoD Information

Technology Security Certification and Accreditation Process) established the DITSCAP as the standard C&A process for the Department of

Defense. The Department of Defense Information Assurance Certification and Accreditation Process (DIACAP) is a process defined by the

United States Department of Defense (DoD) for managing risk. DIACAP replaced the former process, known as DITSCAP, in 2006.

Answer B is incorrect. This DoD Directive is known as National Industrial Security Program Operating Manual.

Answer C is incorrect. This DoD Directive is known as Defense Information Management (IM) Program.

Answer A is incorrect. This DoD Directive is known as Management and Control of Information Requirements.
