A. Safety of the Operating System
Operating system, by nature, is a kind of support software,
which offers a media operation environment and management
for the programs and application system and manages all kinds
of hardware and software. There must be some bugs and
possible problems on the network security in the designing and
developing of the OS which is fully represented in the defects
in the structure of the system. For example, the management of
CPU, internal storagelRAM and external devices are all related
to some program or module, if there is some wrong with the
program and it happens to be connected with a deficient
module by the network, therefore, probably, there will be a
collapse. The hackers always make use of these bugs to attack
and make the system collapse. Besides, the network's
supporting of the following actions such as the transmission of
files, the installation and loading of program and the execution
of files also will result in security problems. If there is a create
process in the OS of a computer, which allows the remote
activation, this kind of machine makes it possible to embed the
unsafe software by using the Remote Access Server. If the
patches are used to put the spy ware into the legal users,
monitor program won't fmd it out, so the computer will be
under the control of the hacker. In addition, The remote
invocation (RMI) of the computer system consists many
intermediate links, which are also easily illegal monitored by
the hackers.
