본문내용

1.1 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 machine
as in a dedicated machine? Explain your answer.
Answer:
a. Stealing or copying one’s programs or data; using system resources
(CPU, memory, disk space, peripherals) without proper
accounting.
b. Probably not, since any protection scheme devised by humans
can inevitably be broken by a human, and the more complex
the scheme, the more difficult it is to feel confident of its correct
implementation.
