In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in various security problems.

a. What are two such problems?

b. Can we ensure the same degree of security in a time-shared a machine as in a dedicated machine?

Explain your answer.

a. What are two such problems?

Denial Of Service (DOS) Attack

One user can stop other users from doing any operations performed on the system.

Integrity of Information

One user can corrupt the confidential information of other users.

Privacy Problem

One user can access the private information of other users secretly.

b. Can we ensure the same degree of security in a time-shared a machine as in a dedicated machine?

• In a dedicated machine the same degree of security as in a time-shared machine is achievable only if when operating system avoids any type of information sharing among the consumers for any purposes read, write who shares the dedicated single computer system.
• Along with this, there is no guarantee regarding bugs in any applications or software, which can also lead to system security vulnerability.
• Hence, these scenarios indicate that there is no total accurate way that can prevent complete data sharing, proper and equal assignment of system assets.
