Network Security
In the last decade, the number of computers in use has exploded. For quite some time now, computers have been a crucial element in how we entertain and educate ourselves, and most importantly, how we do business. It seems obvious in retrospect that a natural result of the explosive growth in computer use would be an even more explosive (although delayed) growth in the desire and need for computers to talk with each other. For quite some time, businesses were primarily interested in sharing data within an office or campus environment, this led to the development of various protocols suited specifically to this task.
Within the last five years, businesses have begun to need to share data across wide areas. This has prompted efforts to convert principally LAN-based protocols into WAN-friendly protocols. The result has spawned an entire industry of consultants who know how to manipulate routers; gateways and networks to force principally broadcast protocols across point-to-point links. Frequently the protocol of choice has been TCP/IP which is also the primary protocol run on the Internet. The emerging ubiquitous ness of TCP/IP allows companies to interconnect with each other via private networks as well as through public networks.
In today’s world businesses, governments, and individuals, all are communicating with each other across the world. While reality is rapidly approaching this utopian picture, several relatively minor issues have changed status from low priority to extreme importance. Security is probably the most well known of these problems. When businesses send private information across the net, they place a high value on it getting to its destination intact and without being intercepted by someone other than the intended recipient. Individuals sending private communications obviously desire secure communications. Finally, connecting a system to a network can open the system itself up to attacks. If a system is compromised, the risk of data loss is high.
It can be useful to break network security into two general classes:
• Methods used to secure data as it transits a network
• Methods which regulate what packets may transit the network
While both significantly affect the traffic going to and from a site, their objectives are quite different.
Transit Security

Conclusion
There are two basic types of network security, transit security and traffic regulation, which when combined can help guarantee that the right information is securely delivered to the right place. It should be apparent that there is also a need for ensuring that the hosts that receive the information will properly process it, this raises the entire specter of host security: a wide area which varies tremendously for each type of system. With the growth in business use of the Internet, network security is rapidly becoming crucial to the development of the Internet. Soon, security will be an integral part of our day-to-day use of the Internet and other networks.

Education is a form of learning that is necessary for the development of one’s personality, identity, physical and intellectual capabilities. Education also provides to the growth of a person through the enhancement of social and professional integration. Education can improve a person’s quality of life. Underprivileged adults and children have a chance to escape poverty. “It is a tool for the economic, social and cultural development of all population around the world. Education is a human right and should be accessible to everyone without discrimination. All children should be awarded the same opportunities to be able to build a future for themselves. Therefore they must and should be able to go to school. Each child have the right to benefit from a quality education that fits their needs.”(Humanium 2016).
What concerns the government of the United States most is the security of the critical infrastructure from the cyber threats. The nation is depending heavily on the technology in most of its critical sectors to keep it up and running. Thus, this makes its more vulnerable to cyber-attacks from outsiders and insiders. Therefore, its protection must be a priority.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
Terrorism is a growing threat in modern times. Ultimately all activities need co-ordination and such co-ordination is facilitated by communication. Terrorist activities need communication as well as any other activity. In order to avoid getting traced, such communication can be done over secure lines on open public networks or hacked private networks.
Within the last decade, the internet has proven to be the most efficient way to complete tasks in today’s society. Every major business in today’s society relies on the internet to conduct business. Though the internet is a useful tool, our reliability on it opens up the door for cyber-attacks that can be detrimental to business as a whole. One example of a cyber-attacks that have recently started becoming more prevalent are DDoS attacks. Recently, DDoS attacks have been a rising issue for businesses owners who run their own servers, such as video game companies and other high profile web servers, including banks and other credit card payment gateways.
Lack of education and poverty often go hand in hand. Education begins at a young age and is an influential factor in determining ones financial status. Today, education remains an inaccessible right for millions of children around the world. More than seventy-two million children of primary education age are not in school and seven hundred and fifty-nine million adults are illiterate and do not have the awareness necessary to improve both their living conditions and those of their children.
Education gives people the skills they need to help move themselves out of a life of poverty and into one of prosperity. Not only does it help people prosper, but with education comes improved health. With the proper education, people are more able to prevent disease and use the health services at their disposal effectively. As well as a greater knowledge of health and how to take care of your body, education helps people earn more money and creates an economic growth. It is shown that in many Third World countries, with each extra year of schooling, people earn ten percent higher wages. The higher wages, in turn, contribute to a national economic growth. Education supports the growth of civil society, democracy, and political stability, permitting people to know about their rights and obtain the skills and awareness needed to use the rights. This is an important article in the argument because it shows the benefits of a substantial education, which many of the Third World countries are
The TCP/IP is the most important internet operation protocol in the world. While IP protocol performs the mass of the functions which is needed for the internet to work. It does not have many capabilities which are essential and needed by applications. In TCP/IP model these tasks are performed by a pair of protocols that operate at the transport layer. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). These two protocols are vital when it comes to delivering and managing the communication of numerous applications. To pass on data streams to the proper applications the Transport layer must identify the target application. First, to be able to attain this, Transport layer assigns an application an identifier. In the TCP/IP model call this identifier a port number. Every individual software process needing to access the network is assigned a un...
For thousands of years cryptography and encryption have been used to secure communication. Military communication has been the leader of the use of cryptography and the advancements. From the start of the internet there has been a greater need for the use of cryptography. The computer had been invented in the late 1960s but there was not a widespread market for the use of computers really until the late 1980s, where the World Wide Web was invented in 1989. This new method of communication has called for a large need for information security. The internet allows people to communicate sensitive information, and if received into the wrong hands can cause many problems for that person.
The world is in another cold war, except this time countries are battling for cyber supremacy. Cyberspace is a massive land of ever-changing technology and personal interaction (McGuffin and Mitchell 1). Cyberspace is not only a place where people post pictures and update their profile, but it also plays an enormous role in running a country. Advanced countries use computers to guide their military, keep track of citizens, run their power grids, and hold plans for nuclear devices and nuclear power. Risks to commercial and government concerns are now being noticed and many countries are taking actions to prevent such threats (McGuffin and Mitchell 1).
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
Some of the world’s poorest countries, with some of the highest child labor and illiteracy rates lie in Sub Saharan Africa. People generally associate the region only with poor economic conditions and all of the social disorder that goes along with 3rd World Status. While some of this reputation is deserved, many people are also failing to see the vast potential for this part of the world. There are several factors that African governments should look into if they want to effectively and efficiently revamp this areas quality of life. One way to do so is by improving the more crucial aspects to healthy functioning region, for example, allowing children to possess their natural rights to a decent education. This could influence an increase in opportunities for economic growth and is therefore a key essential for poverty reduction (BMZ). However, there are many other factors contributing to the continuous complications this area is currently experiencing. In order for Sub Saharan Africa to fully develop and become an economically viable region, it must first address its over growing population crisis, prevent the HIV/AIDS epidemic and thoroughly improve its educational systems.
Due to the demand for the internet to be fast, networks are designed for maximum speed, rather than to be secure or track users (“Interpol” par. 1). The adage of the adage.... ... middle of paper ... ...
