Abstract
With
the
development
of
modern
network
information
technology,
computer
network
has
become
an
indispensable
part
of
people's
life
and
work.
People
become
increasingly
dependent
on
the
network,
information
security
becomes
more
and
more
prominent, large amounts of information
stored in the network, may be illegal intrusion at
any time, there is a serious security
risks. Therefore, the information security of
computer
network becomes more and more
important. This paper introduces the present
situation of
network information
security and protection measures.
Keywords
:
computer
network,

First
Network information security
1.1
Overview of
network information security
Information
security
is
refers
to
the
safety
protection
and
taken
to
establish
the
information
processing
system
of
the
technology
and
the
management,
in
order
to
achieve
electronic
information
confidentiality,
integrity,
availability,
controllability
and
non-repudiation.
In
the
information
age,
the
computer
network
has
become
an
indispensable tool for information
exchange. However, because the computer network is
open,
interconnected,
various
connection
methods
and
terminal
distribution
inhomogeneity, plus technical
weaknesses itself and human negligence, resulting
in the
network is susceptible to
computer viruses, hackers and malicious software.
In the face of
threats
of
invasion
of
network
security,
must
consider
the
security
of
information
this
critical problem.
The security of network information is
divided into two levels of network security
and information security. Network
security including system security, namely
hardware
platform,
operating
system,
application
software;
operation
service
security,
which
ensures
continuity,
high
efficiency
service.
Information
security
mainly
refers
to
data
security, including
data encryption, backup, procedures
etc
.
1.2
Five characteristics of network
information security
(1)completeness
The
information
exchange,
in
the
transmission,
storage
and
processing
remain
unmodified,
non
destructive
and
non
loss
property,
maintain
information
as
is,
so
that
information
can
be
generated
correctly,
storage,
transmission,
this
is
the
most
basic
security features.
(2)Confidentiality
The
information is not leaked to the person, or entity
unauthorized process
according to the
given requirements, or provide the advantage of
features, which put an
end to the
useful information leaked to unauthorized
individuals or entities, emphasizing
the useful information only authorized
feature objects use.
(3)serviceability
Refers
to
the
network
of
information
authorized
entities
can
properly
access,
and
1
normal
use
or
can
recover
the
use
of
features
in
abnormal
conditions
according
to
the
requirements, which can correctly
access the required information in the operation
of the
system, when the system is under
attack or failure, can quickly recover and put
into use.
Usability is a security
measure of network performance of the user
oriented information
system.
(4)non repudiation
The both sides of
communication in the information interaction
process, make sure
the participants
themselves, as well as provide participants with
information true identity,
that all
participants can not be denied or deny my true
identity, and provide information
on
the original and complete the operation and
commitment.
(5)controllability
Refer
to
information
dissemination
of
the
circulation
in
the
network
system
and
specific
content
can
realize
effective
control,
namely
any
information
network
system
should be controlled
in a certain range and storage space. In addition
to the conventional
communication
and
dissemination
of
the
contents
of
this
form
of
site
monitoring,
the
most typical example password managed
policy, when the encryption algorithm by third
party management, must be strictly in
accordance with the provisions of the controllable
execution.
Second
The
current
situation
of
the
network
information
security
The
network information technology development in
China compared with that in
developed
countries,
started
late,
backward
technology,
lack
of
talents,
which
leads
to
safety
in
network
information
in
China
is
relatively
fragile
stage.
But
the
network
information
security
problem
is
still
outstanding,
harm
and
loss
caused
can
not
be
ignored.
2.1
Network threat
diversified
In
recent years, the network threat diversified, the
biggest temptation and network
attack
is
the
economic
interest.
Network
attack
organized,
specific
goal
and
behavior
tendency has
already become a major trend of current network
attack. Network deception
constantly
upgrading,
in
the
current
network
deception
exists
everywhere
in
blackmail

and

trojan,
shows
some
2
lawless
elements
of
network
attack
is
driven
by
economic
interests.
In
addition,
some
hackers are combined to form a group or
organization, in the network attack, the internal
personnel have a clear division of
labor, making malicious code or even destructive
virus,
spread the code so as to obtain
the required information to achieve the attack.
Network
attacks
have
been
from
the
initial
interest
in
network
technology
to
the
illegal
gain
economic benefits in the direction of
change.
2.2
At
present, the network security vulnerability is
high
Is
often
old
vulnerabilities
are
managers
or
network
technology
personnel
repair,
new security vulnerabilities, the more
serious hazards arise. What is more, some hackers
or
network
technology
researchers
found
new
security
vulnerabilities,
does
not
immediately released, but their use,
until the time comes, was released. On the other
hand,
is
managers
do
not
have
time
to
upgrade
and
maintenance
of
the
network
system,
to
create
security vulnerabilities.
2.3
Diversity transmission of
the virus in the form of
Now
the
virus's
function
is
more
and
more
powerful,
concealment
and
self-protection ability
is more and more advanced, so that it can be and
mobile devices
for communication
continuously through the network
system.
Relying on the e-mail to
the
spread
of
the
virus
by
traditional
means
is
not
commonly
used,
hackers
often
use
network
security vulnerability hang virus on the site, and
then allows the user to attack or
virus.
2.4
Bot net is increasing
A
bot
net
is
a
new
term
appeared
in
recent
years,
mainly
refers
to
the
hacker
control a large number of computers on
the network, and use the computer network attack
to
attack
the
formation
of
large-scale
network.
Bot
net
great
harm,
on
one
hand,
it
is
difficult to detect bot net behind the
scenes; on the other hand, the bot net attack,
speed,
obvious
effect,
can
be
in
a
few
minutes
or
even
seconds
of
time
to
let
the
other
side
network paralysis.
2.5
Now
the
rogue
software
is
more
and
more,
disturbs
the
order
of
network
Rogue software refers to those who
provide the normal function of the software, but
in the installation or download time
without the user's consent to install or upload
