Electromagnetic Security:
Electromagnetic security is to prevent unauthorized access to system’s resources due to the issue of electromagnetic emanations from the systems hardware. [1]
Almost every hardware release electromagnetic radiations so there is a risk of leaking out sensitive information. Electromagnetic security has been developed to provide protection to the sensitive data of govt. and business operations. It is installed in telecommunication systems, cryptographic systems and other similar communications systems.
b) What are the three main categories of EMSec. Explain each in detail with at least two examples for each category.
There are three main categories related to EMSec. [3]

International standard related to EMSec :
TEMPEST:
TEMPEST stands for “Transient Electromagnetic Pulse Emanation Standard” refers to counter measures that are setup by US govt. to protect the classified information from being intercepted via electromagnetic emanations. [5]
History: In 1950 the US govt. was concerned that electromagnetic emanations could be intercepted and reconstructed so there is a need for some standard for the protection of data. [5]
Objective: Objective of TEMPEST is to reduce the risk of exploiting emanations from intelligence systems.
TEMPEST provides measures to protect information from unauthorized access due to unintentional emanations. Special shielding is used to suppress the emissions that are emitted from the device. TEMPEST equipment is used to prevent the intruders from getting information through these emanations by using different listening devices. The equipment should meet the standard that is provided by TEMPEST.
The device is metal coated on the outer surface that ensures that it could release only a limited amount of radiations. This technology is expensive and complex so it is used only for highly sensitive

Explain in details.
For protecting the sensitive data access to the unauthorized users via electromagnetic emanations we use different counter measures. The first and most important counter measure is shielding. It is special type of shielding material that does not let any emission to come in and go out. The standard used for electromagnetic security is known as TEMPEST. It is the standard used by the US Govt. to protect the classified information from being intercepted via electromagnetic emanations.
Another method is to paint the devices with the material that absorbs the emissions and it does not let any emission go out.
Another method is to add the white noise to that signal that contains the important data. White noise is spectrum of random electrical signals. If someone is trying to intercept the signal then he will not be able to differentiate between the actual data and the noise.
The Nonstop attack is minimized by using the mobile phone away from the range of 5 meters of
1- A caller contacts a master server, and signals that they would like to establish a call with a responder. 2- The responder receives an encrypted signal, connects to the master server, and indicates that it has received the call signal. 3- If the responder chooses to answer the call, then it is relayed through the closest available relay server.
Wifi WPS: It stands for “Wi-Fi Protected Setup” and provides simplified mechanisms to configure secure wireless
It offers a secure fitting together between internet browsers and websites, letting you to communicate secretive data online. Physical Layout • Topologies; topology can be measured as a computer-generated nature or construction of a system. This shape does not agree to the real physical plan of the policies on the computer network. • Ring; basically in a ring system each device (workplace, waiter, and copier) is related to two other devices, this systems a ring for the signs to travel around. Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it.
(Androulidakis. 2012). There are different solutions to isolate a mobile phone from electro-magnetic radiation, and probably the best one is the use of a cage called “Faraday Cage”. The use of this solution is recommended not only because the isolation from external
The device is very useful, as whenever any application is run on your device, the user is notified whether it is not secure after the identification is done. It offers a high level of security compared to antivirus programs since it is not vulnerable to credential hijacking and insider tampering. Also, this feature is capable of working virtually, meaning that in any case the OS is compromised in any way, then the Device guard will not be affected in any way but it will continue to work
Officers can just turn off the phone or remove its battery. Another option is placing the phone in an enclosure that isolates it from radio
1. Write a brief introduction about the diagnostic imaging modality. Nuclear medicine is a section of medical imaging that uses radioactive medication known as radiotracers or radiopharmaceutical (Understanding nuclear medicine, 2009). Radiotracers are given to the patient through injection, swallowing or inhalation, which makes the body radioactive for a short time. The radiation is detected by a special camera, and then the image is produced.
Explain how the ethos, mission, aims and values of a school may be reflected in working practices. The ethos, mission, aims and values of the school should be known very well before entering the school setting as it is part and parcel of the environment of the school and the daily practice of the staff and pupils there. All adults that work and are part of setting have the responsibility to model the standards of behaviour, with the children and amongst the colleagues. Good association and strong dealings between adults will encourage the good behaviour in children. All children as an individual should be respected within the school.

Why You Should Spy on Mobile Phones If you are the one, who wants to track anybody’s phone, you shouldn’t be ashamed of this. Besides, we live in the epoch of a fast development of modern technologies. So, it is a sin not to make use of the benefits of these achievements. Furthermore, all these James Bond games became really easier due to phone monitoring software. You can find out any information about all subjects of your interest with the help of phone monitoring applications.
These technological services help us to make our lives a little more pleasant and easier. However, same as their advantages, these technologies possesses a great number of disadvantages. The more advanced society becomes technologically, the more people begin to depend on computers and other forms of technologies for everyday lives. Anyone from anywhere can get access to our private information.
This code is used for Emergency Signaling (SOS) for all kinds of receivers. This code can also be used by the people with several disabilities. The Morse code is mostly used by the hams because they ensure systematic transmission of the signals. However, it is not very easy to learn these codes.
GLOBALIZATION, TECHNOLOGY AND LAW Globalization and Technology Globalization has completely transformed the way in which the world and its people interact. Earlier there were several roadblocks in the ability to communicate and interact with the people worldwide. But now, the world is becoming more and more globalized in all spheres: Business, financial, social, economical, etc. Over the years, a lot of technological advancements have come into picture including the changes in the field of Information Technology, having a significant impact on the global landscape.
It relies on sets of numbers stored in electromagnetic format used to create representations and simulations that correspond to material performance and to map out built
So in plain language, it is a military weapon to protect ballistic missiles.
