a.
- One user can read the private data of another user-privacy.
- One user can prevent another user from getting anything done-denial of service.
Indeed, in any multiprogramming and time-sharing environment since the computers of users are networked together, then it is very possible for a bad actor to read the private data of another user, or even prevent another user from accessing their computer by employing a denial of service attack on the network. In other words, the network would be unable to handle the request of users since has been overloaded by another user.
b. a. Yes - if we can ensure that the operating system prevents any sharing of data between users, either for reading or writing and fairly shares the computer, then we can achieve the same level of security.
Answer:
Option (A) is the correct answer.
Explanation:
A Computer system can be the target for the crime on which a criminal can acquire the information from the computer system which is stored on it. A Criminal is targeting the system with the help of some software that is entered on the computer system through a network.
In the above question, paragraphs are describing the content related to the crime which targets the computer system. This is a concept of a "computer as target". Hence option "A" is the correct answer while the other is not valid because--
- Option b suggests the concept behind the storage device of a computer but in the question, it is about the crime of a computer.
- Option c suggests the concept behind the computer is a criminal but in the question, it is about the crime of a computer.
- Option d suggests the concept behind the communication of a computer but in the question, it is about the crime of a computer.
