Digital rights management (DRM) is an access control technology used by hardware manufacturers, publishers, copyright holders and

individuals to impose limitations on the usage of digital content and devices. It describes the technology that prevents the uses of digital

content that were not desired or foreseen by the content provider.

DRM does not refer to other forms of copy protection which can be circumvented without modifying the file or device, such as serial numbers or

keyfiles. It can also refer to restrictions associated with specific instances of digital works or devices.

Answer C is incorrect. Code signing is the process of digitally signing executables and scripts in order to confirm the software author,

and guarantee that the code has not been altered or corrupted since it is signed by use of a cryptographic hash.

Answer A is incorrect. A hypervisor is a virtualization technique that allows multiple operating systems (guests) to run concurrently on a

host computer. It is also called the virtual machine monitor (VMM). The hypervisor provides a virtual operating platform to the guest operating

systems and checks their execution process. It provides isolation to the host's resources. The hypervisor is installed on server hardware.

Answer B is incorrect. Grid computing refers to the combination of computer resources from multiple administrative domains to achieve

a common goal.

The Chinese Wall Model is the basic security model developed by Brewer and Nash. This model prevents information flow that may cause a

conflict of interest in an organization representing competing clients. The Chinese Wall Model provides both privacy and integrity for data.

Answer D is incorrect. The Biba model is a formal state transition system of computer security policy that describes a set of access

control rules designed to ensure data integrity. Data and subjects are grouped into ordered levels of integrity. The model is designed so that

subjects may not corrupt data in a level ranked higher than the subject, or be corrupted by data from a lower level than the subject.

Answer C is incorrect. The Clark-Wilson model provides a foundation for specifying and analyzing an integrity policy for a computing

system. The model is primarily concerned with formalizing the notion of information integrity. Information integrity is maintained by preventing

corruption of data items in a system due to either error or malicious intent.

The model's enforcement and certification rules define data items and processes that provide the basis for an integrity policy. The core of the

model is based on the notion of a transaction.

Answer A is incorrect. The Bell-La Padula Model is a state machine model used for enforcing access control in government and military

applications. The model is a formal state transition model of computer security policy that describes a set of access control rules which use

security labels on objects and clearances for subjects. Security labels range from the most sensitive (e.g.,'Top Secret'), down to the least

sensitive (e.g., 'Unclassified' or 'Public').

The Bell-La Padula model focuses on data confidentiality and controlled access to classified information, in contrast to the Biba Integrity Model

which describes rules for the protection of data integrity.

A hot site is a duplicate of the original site of the organization, with full computer systems as well as near-complete backups of user data. It

provides the backup facility, which is maintained in a constant order, with a full complement of servers, workstations, and communication links

ready to assume the primary operations responsibility.

A hot site is a backup site in case disaster has taken place in a data center. A hot site is located off site and provides the best protection. It is

an exact replica of the current data center. In case a disaster struck to the data center, administrators just need to take the backup of recent

data in hot site and the data center is back online in a very short time. It is very expensive to create and maintain the hot site. There are lots

of third party companies that provide disaster recovery solutions by maintaining hot sites at their end.

Answer A is incorrect. A cold site is a backup site in case disaster has taken place in a data center. This is the least expensive disaster

recovery solution, usually having only a single room with no equipment. All equipment is brought to the site after the disaster. It can be on

site or off site.

Answer D is incorrect. Mobile sites are self-reliant, portable shells custom-fitted with definite telecommunications and IT equipment

essential to meet system requirements. These are presented for lease through commercial vendors.

Answer C is incorrect. A warm site is, quite logically, a compromise between hot and cold sites. Warm sites will have hardware and

connectivity already established, though on a smaller scale than the original production site or even a hot site. These sites will have backups

on hand, but they may not be complete and may be between several days and a week old. An example would be backup tapes sent to the

warm site by courier.

You will most probably find this information in the Service Level Agreement document. Amongst other information, SLA contains information

about the agreed Service Hours and maintenance slots for any particular Service.

Service Level Agreement (frequently abbreviated as SLA) is a part of a service contract where the level of service is formally defined. In

practice, the term SLA is sometimes used to refer to the contracted delivery time (of the service) or performance.

Service Level Agreement (SLA) is a negotiated agreement between two parties where one is the customer and the other is the service

provider. This can be a legally binding formal or informal 'contract'. Contracts between the Service Provider and other third parties are often

(incorrectly) called SLAs, as the level of service has been set by the (principal) customer there can be no 'agreement' between third parties

(these agreements are simply a 'contract'). Operating Level Agreements or OLA(s) however, may be used by internal groups to support SLA

(s).

Answer B is incorrect. Release Policy is a set of rules for deploying releases into the live operational environment, defining different

approaches for releases depending on their urgency and impact.

Answer C is incorrect. The Service Level Requirements document contains the requirements for a service from the client viewpoint,

defining detailed service level targets, mutual responsibilities, and other requirements specific to a certain group of customers.

Answer D is incorrect. Underpinning Contract (UC) is a contract between an IT service provider and a third party. In another way, it is

an agreement between the IT organization and an external provider about the delivery of one or more services. The third party provides

services that support the delivery of a service to a customer. The Underpinning Contract defines targets and responsibilities that are required

to meet agreed Service Level targets in an SLA.

At this point all that Rob can likely do is accepting the risk event. Because this is an external risk, there is little that Rob can do other than

document the risk and share the new with management and the project stakeholders. If the law is passed then Rob can choose the most

appropriate way for the project to continue.

Acceptance response is a part of Risk Response planning process. Acceptance response delineates that the project plan will not be changed

to deal with the risk. Management may develop a contingency plan if the risk does occur. Acceptance response to a risk event is a strategy

that can be used for risks that pose either threats or opportunities. Acceptance response can be of two types:

Passive acceptance: It is a strategy in which no plans are made to try or avoid or mitigate the risk.

Active acceptance: Such responses include developing contingency reserves to deal with risks, in case they occur.

Acceptance is the only response for both threats and opportunities.

Answer B is incorrect. Mitigation aims to lower the probability and/or impact of the risk event.

Answer C is incorrect. Transference transfers the ownership of the risk event to a third party, usually through a contractual agreement.

Answer D is incorrect. Enhance is a risk response that tries to increase the probability and/or impact of the positive risk event.
