“SECURITY” in this contemporary scenarios has become a more sensible issue
either it may be in the “REAL WORLD” or in the “CYBER WORLD”.
In the real world
as opposed to the cyber world an attack is often preceded by information gathering.
Movie gangsters “case the joint”; soldiers “scout the area”. This is also true in the cyber
Here the “bad guys” are referred to as intruders, eavesdroppers, hackers,
The intruders would first have a panoramic view of the victims network
and then start digging the holes.
Today the illicit activities of the hackers are growing by
leaps and bounds, viz., “THE RECENT ATTACK ON THE DNS SERVERS HAS
CAUSED A LOT OF HULLABALOO ALL OVER THE WORLD”.
fortunately, the antagonists reacted promptly and resurrected the Internet world from the
brink of prostration.
Since the inception of conglomerating Computers with Networks the consequence
of which shrunk the communication world, hitherto, umpteen ilks of security breaches
took their origin.
Tersely quoting some security ditherers – Eavesdropping, Hacking,
Hijacking, Mapping, Packet Sniffing, 1Spoofing, DoS & DDoS attacks, etc.
law says “Every action has got an equal but opposite reaction”.
So is the case with this.
Nevertheless the security breaches and eavesdroppers, the technological prowess has
been stupendously developed to defy against each of the assaults.
Our paper covers the
ADVANCED technical combats that have been devised all through the way, thus giving
birth to the notion of “NETWORK -SECURITY”.
Various antidotes that are in fact
inextricable with security issues are – Cryptography, Authentication, Integrity and Non
Repudiation, Key Distribution and certification, Access control by implementing
Firewalls etc. To satiate the flaws in the network security more and more advanced
security notions are being devised day by day.
Our paper covers a wide perspective of
such arenas where the contemporary cyber world is revolving around viz., , THE DMZ
AUTHENTICATION SYSTEM. Palladium is a content protection concept that has
spawned from the belief that the PC, as it currently stands, is not architecturally equipped
to protect a user from the pitfalls and challenges that an all-pervasive network such as the
Internet poses. In the course of this paper the revolutionary aspects of palladium are
discussed in detail. Case study to restructure the present data security system of JNTU
examination system using palladium is put forward.
