NETWORK SECURITY

NETWORK SECURITY Network security is defined in this paper on the basis of Honeynet Technology in reference to honeypots.Honeynet and Honeypots are used in the area of Computer Networks and Network Security. Honeypots are a novel approach to network security and security research alike. The primary purpose of a honeynet is to gather information about threats and this information is to better understand threats, how they are evolving and changing, and how to best counter those threats.Intrusion to a network or system can never be eliminated but however can be reduced . Any traffic to or from the Honeynet is suspicious in nature. Thus traffic from a Network to a machine on the Honeynet may indicate a better network system. The purpose of this paper is to discuss what a honeynet is, its value, an overview of how it works, and the risks/issues involved. Then look at the nuts and bolts of honeypots by putting them together. Finally, we shall conclude by looking at what the future holds for honeypots and honeynets networks can be used to increase network security in a large organizational Envorinment.

ETHICAL HACKING

Information security is the fastest growing area in the Information Technology (IT) sector Security would be an easy process if all that had to be done is to install a fire wall and anti - virus software, but the reality is that securing information requires a multi - layered approach. Obtaining this requires adopting measures to prevent the unauthorised use, misuse, modification or denial of use of knowledge, facts, data, or capabilities and it requires taking a proactive approach to manage the risk. This is where ethical hackers come into real play. Ethical hacking is an "art" in the sense that the "artist" must possess the skills and knowledge of a potential attacker (to imitate an attack) and the resources with which they mitigate the vulnerabilities used by attackers. Ethical hacking is the process of analyzing the imposed threat on a given system or network by modelling the actions of an adversary. This paper describes ethical hackers: their skills, their attitudes, and how they go about helping their customers find and plug up security holes. The ethical hacking process is explained in detail. Succesful ethical hackers possess a variety of skills. First and foremost, they must be completely trustworthy. The ethical hacker often holds the " keys to the company," Modern security efforts have to plan for the unplanned and anticipate attacks before they occur. Ethical Hacking is in the boom and it''s high time every company recognizes the need of a potential professional ethical hacker. Ethical hacking is not just necessary; it is inevitable.

TSUNAMI DETECTION BY HUMAN

TSUNAMI MONITORING SYSTEM
USING RTK - GPS AND GPS BUOY
A new tsunami observation system has been developed,
which employs the RTK _ GPS technique to detect a
tsunami before it reaches the coast.
The system consists of dual - buoys : The support - buoy,
which is sensitive to wind waves, and the sensor - buoy,
is of a spar - type and is insensitive to wind - waves. Both
buoys are equipped with a GPS antenna. An experiment
using this system was carried out for about nine days in
March 1999. Observation data were monitored at the onshore
base station. The results showed that hourly avrage data is
consistent with ocean tides for both buoys.
The sensor - BUOY was found not to respond much to wind
waves compared to the support - buoy.
Thus, it may be preferable to use a spar - type buoy for
detecting a tsunami efficiently.
Further more, a simple frequency analysis showed that
a tsunami could be easily separated from higher frequency
wind waves if tsunami is superimposed on regular wind .

WIRLESS TRANSMISSION OF POWER

WIRELESS POWER GENERATION USING S.P.S AND RECTENNA Can''''t we use solar power at the night? This question may look somewhat absurd since there is obviously no meaning of " Using solar power at night"! Now-a- days we are using the solar power to generate electricity by the solar panels mounted on the earth. But in the outer space, the sun always shines brightly. No cloud block the solar relays, and there is no night time. Solar collectors mounted on an orbiting satellite would thus generate power 24 hours per day, 365 days per year. If this power could be relayed to earth, then the world''''s energy problems might be solved forever. We propose a new method for power generation in which the solar power is converted into microwaves through satellites called power satellites (SPS) and it is received using a special type of antennae called rectenna, mounted on earth surface. The concept of free space power propagation is not a new concept and it is the topic of discussion for nearly four decades. This paper explains the same for the generation and reception of electrical power using the rectennas. Rectennas are special type of antennae that could convert the incoming microwave radiation into electricity and this electricity can be sent to grids for storage and future usage

SCIENTISTS SEE THROUGH RUSSIA''S GIRL WITH X- RAY VISION

When German physicist Wilhelm Roentgen annonced that he had
discovered an invisible form of radiation that could make
photographs of the bones and organs inside the human body,
many scientists wrote it off as a hoax. But his discovery
changed the face of medicine.
Now ,a teenage girl from Saransk, Russia, claims to have
X - ray like visison, which lets her see inside of human
bodies, and is able to make diagnosis that often are more
accurate than those of doctors.
Widely hailed in Russia as " the girl with X - ray eyes",
17 -year-old Natasha Demkina has growing following of
patients, doctors, journalists, and others who are convinced
her powers are real.
Dr.Hyman, professor emeritus of psychology at the university
of oregon and Dr Wiseman, Professor of psychology at university
of Hertfordshire, UK , have extensive experience in testing
people who claim paranormal powers.
Based on preliminary research, suspected Natasha may be using
a remarkably simple but convincing technique called "cold reading",
which is commonly used by psychics, astrologers, and other fortune
tellers.
Natasha scans her patients from head to toe and describes a long
list of abnormalities she says she sees.
When Natasha gave a reading on one of the test patients, she
disclosed several facts that neither the patient nor his physician
knew. And the only way to verify these problems was through autopsy.
so a simple test was designed that would eliminate the possibilities
of using cold reading to fish for correct information and to prevent
Natasha from making diagnoses that could not be disproved with out
an autospy.

Six volunteers with different medical conditions that showed up on X -ray
and one normal subject were chosen. Natasha was handed six test cards,
each with a description of a target medical condition.
Natasha claims she can see abnormalities down to the cellular level
and her mother says her readings are 100 percent accurate.
So the test - which required her to match at least five of the target
medical conditions to the correct subjects - should have been a breez.
yet she only matched four of the conditions correctly.
Natasha''s most dramatic misdiagnosis was her failure to see a large
metal plate covering a missing section of skull in a man who had
a large brain tumour removed. Instead, she indicated that she "saw"
tal plate and missing skull section in a man who had a normal
skull.
