Cyber Security Geo location

In Cyber security most important topic is Geo Location, by currently technology this plays a vital role.

Electromagnetic Radiation:

• Electromagnetic radiation is a radiant energy, this em light is invisible, such as radio, infrared, and x rays.
• The speed at which this waves oscillates is known as frequency.

Decibels:(dB)

• Decibels logarithmic unit is dB is used to express the ratio of two values of quantity.
• dB means it is a Isotropic physical property that has the same value when measured from different directions.

War driving:

• Electron leaving antenna are equivalent to some one yelling loudly.
• Using war driving attacker decrypt the signal in moving vehicle which is illegal to our law. Apart from country security issues.

Netspot - used to find radio signal leak for windows and mac.
Kismet-used to find wireless intrusion in Linux system.
WIGLE WiFi - used by Android to find the wireless intrusion.

Antenna:
Antenna has 8 dB isotropic value.

Yagi-Uda Antenna:
Yagi uda antenna is a directional antenna it has the value of 17 dB.
Yagi-Uda antenna every 3dB increase is a doubling of the power or intensity.

Omni directional antenna:
Omni directional works in all direction and it has overall gain of 15 dB.

WiFi access:
For WiFi every SSID will be unique in name

Top ten SSID includes xfinity WiFi, linksys, <no SSID>, NETGEAR, dlink, ziggo, HP setup(adhoc)
