Cyber security is of paramount importance in view of
continuing cyber attacks and increasing range of malware and viruses. Most
organizations and enterprises run their business online and hence are connected
to the Internet and other private networks. This exposes them to a variety of
risks, which includes identity thefts and loss of crucial data. Loss of
critical data can cause great damage to any organization, and can even close
down a business enterprise. A strong cyber security system is the first line of
defense for data loss prevention, which can be supported by a good backup
solution.
Cyber security has now much broader implications, and has to
be addressed as a risk management issue of the entire enterprise, rather than
merely an IT problem. Security breaches are now common, in not only consumer
and financial systems, but also in systems of industrial control, as most
systems now use open technologies and platforms. The first line of defense
would obviously be early detection of an attack or malware, and in this aspect,
deep packet inspection plays an important role.
Deep packet inspection is a
type of filtering system that examines network data packets especially the
header, for non-compliance of protocol. This will usually reveal whether it is
a malware, intrusion, or some form of spam. The deep packet inspection system
then decides whether such packet has to be let through, or diverted to another
destination for further analysis and statistical information.
Although a strong defensive and filtering architecture forms
the basis of a good network security system, it should also have an effective incident
response plan to counter new threats. In today's world, a computer system will
be bombarded with numerous cyber attacks daily, and if the defense mechanism
fails to cope with the new threat, there should be an incident response plan in
place to control the damage or counter the attack effectively in a timely
manner. Incident response is now becoming an important aspect of protection and
data loss prevention at the national level, and governments of various
countries are forming expert teams and procedures for combating new cyber
threats.
It is not possible to have a foolproof system, as cyber
criminals keep improving their techniques and come out with superior malware.
Cyber security is an evolving science as new methods and techniques are
developed constantly in view of new threats. However, the basic principles and
strategies have remained the same, and they still play an important role in
developing an effective system for security. In addition, having an effective
online backup solution is an important aspect of a security system. With a good
backup plan, there is hardly any risk of data being lost, even in the worst
cyber attack.
