Answer:

d. Inheritance.

Explanation:

The two classes are book and novel.

Since the class novel is derived from the class book, then the relationship between them (these objects) is inheritance. Inheritance is "is-a" relationship.

In this case, a novel "is a" book.

Inheritance is one of the principles of object oriented programming (OOP) in which a class, called the sub class or child class, derives, extends or inherits features of another class, called the super class or parent class or base class. In other words, in inheritance, a sub class is derived from another class in such a way that these classes have an "is-a" relationship.

In this case, the novel is the sub or child class while the book is the super, base or parent class.

blagie [28]

Answer:

Discretionary Access Control model

Explanation:

Discretionary Access Control (DAC) gives owners of a resource full control of objects/items they have created or been given access to, this also includes sharing the objects/items with other subjects. These owners have control over their data and maintain access through ACLs. The access-control list (ACL), is a list of permissions attached to an object in a computer file system.

The Owners can decide to grant other users access to their files, change their attributes, alter them, or delete them. DACs are discretionary because the owner can transfer information access to other users.

A group of accountants encrypt the emails they send to your company because they contain highly sensitive financial information.

Answer:

a) Generate a new public and private key

Explanation:

You encrypt a message using the recipient's public key and the recipient decrypts the message using his own private key. Only the public key can be known by an external agent. The private key is for the individual and is not expected to be shared. In the event that the recipient cannot decrypt the message, it is unsafe to send one's private key to him. He does not even need one's private key to decrypt the message, he needs his own private key.

The best thing to do is to generate another means of security by generating new public and private key so that the sender encrypts the message with the new public key and the receiver decrypts it using his new private key.

Option B is wrong because, if the encryption is removed, the aim, which is to secure the message from intruders is not achieved.
