Confidential data residing on a PC is BEST protected by:
A. a password.
B. file encryption.
C. removable diskettes.
D. a key operated power source.
Answer / guest
Answer: B
File encryption is the best means of protecting confidential
data in a PC. A key-operated power source, password or
removable diskettes will only restrict access, and the data
will still be viewable using electronic eavesdropping
techniques. Only encryption provides confidentiality. A
password also may not be the best method of protection since
passwords can be compromised. Removable diskettes do provide
some security for information if they are locked away so
only authorized individuals can gain access. However, if
obtained by unauthorized individuals, information can be
accessed easily. A key-operated power source can be bypassed
by obtaining power from another source.
