Threats Network Security Protects Against
Top Reasons You Need Network Security
Whether you engage in global commerce or have a network
established simply to communicate with others on the Web, there
are a number of threats that exist when operating in the realm
of the World Wide Web. Network security is an important function
that ultimately will protect your computer and data from
multiple threats. Here are some examples of common threats
networks are exposed to every day:
Session Hijackers - Hijackers can access your computer in a
number of ways. One way they can do this is through SMTP
hijacking. This means a hijacker can gain access to your list of
e-mail addresses through an SMTP server of an unprotected host.
By doing so a hijacker is able to send spam to any users listed
in the e-mail address book. This is actually a frequent problem
networked computers have to deal with. It is usually very
difficult to track the origin of a spammer in this case as email
is usually redirected through various hosts.
Backdoors - Certain programs allow remote access through
application backdoors. Still others have glitches or bugs in the
system that allow someone to gain access to the network via a
backdoor. This is very dangerous as the interloper can then take
control of multiple programs.
Remote login - In some situations a person can connect to your
computer network from a remote location and take control of
certain computer functions. They may for example view or change
files and run programs unbeknownst to you on your computer
network.
