Answer : B

The Internet Security Glossary (RFC2828) defines an attribute certificate as a digital certificate that binds a set of descriptive data items, other than a public key, either directly to a subject name or to the identifier of another certificate that is a public-key certificate. A public-key certificate binds a subject name to a public key value, along with information needed to perform certain cryptographic functions. Other attributes of a subject, such as a security clearance, may be certified in a separate kind of digital certificate, called an attribute certificate. A subject may have multiple attribute certificates associated with its name or with each of its public-key certificates.

Answer : A

If you are 'retrofitting' that means you are adding to an existing database management system (DBMS). You could go back and redesign the entire DBMS but the cost of that could be expensive and there is no telling what the effect will be on existing applications, but that is redesigning and the question states retrofitting. The most cost effective way with the least effect on existing applications while adding a layer of security on top is through a trusted front-end.

Clark-Wilson is a synonym of that model as well. It was used to add more granular control or control to database that did not provide appropriate controls or no controls at all. It is one of the most popular model today. Any dynamic website with a back-end database is an example of this today.

Such a model would also introduce separation of duties by allowing the subject only specific rights on the objects they need to access.

The following answers are incorrect:

trusted back-end. Is incorrect because a trusted back-end would be the database management system (DBMS). Since the question stated 'retrofitting' that eliminates this answer.

controller. Is incorrect because this is a distractor and has nothing to do with 'retrofitting'.

kernel. Is incorrect because this is a distractor and has nothing to do with 'retrofitting'. A security kernel would provide protection to devices and processes but would be inefficient in protecting rows or columns in a table.

Answer : D

Answer : B

RC2, RC4, RC5 and RC6 were developed by Ronal Rivest from RSA Security.

In the RC family only RC4 is a stream cipher.

RC4 allows a variable key length.

RC2 works with 64-bit blocks and variable key lengths,

RC5 has variable block sizes, key length and number of processing rounds.

RC6 was designed to fix a flaw in RC5.
