On your personal computer, who can install programs? Who can change operating system data? Who can replace portions of the operating system? Can any of these actions be performed remotely?

What will be an ideal response?

Who
can
install
programs?
Depending
on
the
OS
and
the
program
being
installed,
possible
answers
include
anyone
with
an
administrator
password
or
any
user.
Who
can
change
OS
data?
Most
likely,
only
users
with
administrative
privileges.
Who
can
replace
portions
of
the
operating
system?
Anyone
who
can
install
OS
patches—generally
administrators—can
technically
replace
portions
of
the
OS.
Can
any
of
these
actions
be
performed
remotely?
These
actions
can
generally
be
performed
remotely
if
the
student's
system
is
running
a
remote
desktop,
remote
shell
(e.g.,
telnet,
SSH),
or
similar
service
and
is
Internet-­?connected.
These
actions
may
also
be
performed
remotely
if
an
attacker
gains
access
to
the
system.
