Explanation:
In an electronic vaulting scenario, database backups are transferred to a remote site using bulk transfers.
The transfers occur in infrequent batches.
Incorrect Answers:
A: With remote journaling, data transfers are performed in a expeditious manner. Data transfers occur in a bulk transfer mode, but they occur on a frequent basis, usually once every hour if not more frequently.
C: Data clustering does not include batch processing dumping data at an alternate location.
D: Database shadowing is remote journaling to more than one destination duplicate server. Remote journaling is Batch processing dumping backup data to an alternate location.

The correct answer is "Enrollment time".
Answers Set-up time and Log-in time are distracters.
Answer throughput, refers to the rate at which individuals once enrolled can be processed and identified or authenticated by a biometric system.

The goal of a noninterference model is to strictly separate differing security levels to assure that higher-level actions do not determine what lower-level users can see. This is in contrast to other security models that control information flows between differing levels of users, By maintaining strict separation of security levels, a noninterference model minimizes leakages that might happen through a covert channel.
The model ensures that any actions that take place at a higher security level do not affect, or interfere with, actions that take place at a lower level. It is not concerned with the flow of data, but rather with what a subject knows about the state of the system. So if an entity at a higher security level performs an action, it can not change the state for the entity at the lower level.
The model also addresses the inference attack that occurs when some one has access to some
type of information and can infer(guess) something that he does not have the clearance level or
authority to know.
The following are incorrect answers:
The Bell-LaPadula model is incorrect. The Bell-LaPadula model is concerned only with
confidentiality and bases access control decisions on the classfication of objects and the
clearences of subjects.
The information flow model is incorrect. The information flow models have a similar framework to
the Bell-LaPadula model and control how information may flow between objects based on security
classes. Information will be allowed to flow only in accordance with the security policy.
The Clark-Wilson model is incorrect. The Clark-Wilson model is concerned with change control
and assuring that all modifications to objects preserve integrity by means of well-formed
transactions and usage of an access triple (subjet - interface - object).

The MIME protocol specifies a structure for the body of an email message. MIME supports a number of formats in the email body, including graphic, enhanced text and audio, but does not provide security services for these messages. S/MIME defines such services for MIME as digital signatures and encryption based on a standard syntax. *Answer IPSEC is incorrect since IPSEC is not an email protocol but is a standard that provides encryption, access control, nonrepudiation, and authentication of messages over IP. It is designed to be functionally compatible with IPv6. Answer b is incorrect because PGP, Pretty Good Privacy, brings security to email through the use of a symmetric cipher, such as IDEA, to encipher the message. RSA is used for symmetric key exchange and for digital signatures. PGP is not an augmentation of MIMe. RFC 2440 permits other algorithms to be used in PGP. In order of preference, they are ElGamal and RSAfor key distribution; triple DES, IDEAand CAST5 for encryption of messages; DSA and RSA for digital signatures and SHA-1 or MD5 for generating hashes of the messages. Answer d is incorrect because there is no such protocol. There is a protocol called SET for Secure Electronic Transaction. It was developed by Visa and MasterCard to secure electronic bankcard transactions. SET requests authorization for payment and requires certificates binding a person's public key to their identity.
