Network Security And The Internet

Cyber security threats change quickly as Internet increases, and also the related dangers are getting to be progressively international. Being covered against cyber security threats requires almost all end users, actually the most complex versions, to know the particular threats in addition to enhance their particular safety measures with a continuing foundation. On April 28, 2014 President Obama has declared that the “cyber threat is one of the most serious economic and national security challenges we face as a nation” and that “America 's economic prosperity in the 21st century will depend on cyber security.” The internet enables and also helps people in a many ways and a example is collect, store, process huge amounts of data, which includes vulnerable data of small business, transactional and personal. Everything in this world is based on internet now a days.

Despite the presence of network security devices such as firewalls and other security appliances, today's corporate networks are still vulnerable to both internal and external attacks by hackers intent on creating havoc. By proactively

Internet security are such a big thing because many things are based off the internet. As in most of the storage is done off of cloud storage, so you don’t need lots of storage in your computer. Which makes internets unsafe because anyone could hack into your account and take your information. Like your bank account and your personal accounts that could really hurt you I the long run. Or someone could put a scam on a common website that most people go on. And could hack everyone’s computer that has the scams. Another way of spamming is by hacking into someone else email and sending them spam that looks like legitimate with a subject or message. Fooled sender email addresses, logos, trademarks, and the wording used in the message will often add to the trick.

Cyberspace is now a military dimension; the word “cyber is a very significant and probably one of the most common term used in today’s international security dialogues. The Internet and e-commerce are crucial to the economic competitiveness of many nations, businesses and organizations, however cyber criminal have cost users millions of dollars and valuable assets. Achieving security on the Internet is a very daunting task; as criminals and hackers have become plagues to critical IT infrastructures, online communication and e-commerce.

After the September 11 terrorist attack in the U.S, the federal government through all the law enforcement agents ensured a review of security measures across the nation. The measures mostly focused on possible threats in areas considered high risk targets for terrorists. Other than the physical locations, significant attention has of late been accorded to computer as well as telecommunication systems as a result of possible network security vulnerability (The National Academies, 2015). The need to focus on cybersecurity is attributed to the fact that much of modern life relies significantly on the use of computers as well as computer networks. The computers and networks prove critical in important functions that include management and operation of nuclear power plants, financial infrastructure, controlling the air traffic systems and power grid among others. Computers also prove essential in the management of day-to-day operations of governments and organizations. Management of payrolls, tracking of sales and

Computing technology has changed the way users work, learn and play-More businesses have gone online. They have turned into a vital piece of our regular presence. These computer system are vulnerable against various internal/external threats like malware in both homes business and environments and this has rapidly escalated firmly over the past several years. Information in this systems needs to be protected from intruders because it’s an essential asset in the organisation. Three basic important things need to be supplied is integrity confidentiality and availability of information. The diversity of risk to the network computing by disenchanted attacks has intensely maximised worldwide. This is according to the U.S federal bureau of investigation .The digital attacks globally have reached 20,000 in January causing more than 8 billion dollars damage (Mueller, 2003).

In the beginning network protocols that formed part of the Internet infrastructure were designed without security in mind. Without a fundamentally secure infrastructure, network defense becomes more difficult. Furthermore, the Internet is an extremely dynamic environment in terms of both topology and emerging technology.

Threat to internet security is one of the main challenges which internet users face during electronic transactions. This is a tree branch of computer security which also includes browser security, and network security. The internet security’s main objective is to take measures for restricting or controlling various attacks. An insecure channel for transferring information leads to various types of frauds and intrusion such as virus, phishing, Trojan horses, worms, boot sector viruses adware and spyware. Various types of anti- malware and technologies are used for securing the internet. For example, PGP and MIME technologies are used for email security, SSL and TLC are used for web traffic security and IP Sec is used for network layer security.

Computer networks have changed the way individuals and organizations conduct daily activities. Individuals have been using the internet for many years now and it has increased its presence around the world. The internet, as the name suggests, is a network of computers that can share resources, simplify communications, and provide information. Organizations utilize the networks for the same reasons as individuals do; however, they also allow organizations to conduct business and increase productivity. Unfortunately, even though computer networks have increased the effectiveness and productivity of organizations, it comes with a price. That price involves the increasing threat that internal and external threat actors can cause an organizations network. Network security is a very important segment in an organizations overall cybersecurity policy. However, the issue with network security is its static form of defense that is rapidly losing against current and future dynamic threats.

Abstract: Networks have worked their way into the everyday lifestyle of most individuals in the world, businesses especially rely on the networks for efficiency and globally reach. With the huge demand for network usage it is easy to recognize why these systems are a huge target for hackers and other ill intenders. Securing these popular networks should be a top concern for anyone or organization that maintains one, additionally anyone using a network has to be able to traverse the dangerous virtual roadway and be able to identify common concerns that may arise should some suspicious activity arise.

The development of technology has brought Internet to become the mass communication media between people or companies. Through Internet, people can communicate with other people in various places. Companies can get many advantages by using Internet network to support their business. Therefore, companies are trying as hard as they can, and give high effort in protecting their network from attack and make sure that they have the best network security.

The primary objective of a network security system is to, in a cost effective manner, balance convenient access to legitimate users and inaccessibility to attackers. In a nutshell, the goal is to prevent connectivity to anyone intending to cause harm to the network. The harm to which this paper refers can come in the following forms:

The world is more connected now than ever since the birth of the Internet and with the new networking technology coming out, will continue this way. There is a large amount of personal, business, and government information on the internet and network infrastructures. Network security is becoming of great importance because of the attacker 's ability to steal this information that can be easily acquired through different means of attacks. The internet itself along with network infrastructures has many security risks in it. Knowing what attack methods are out there allows users a chance to defend against them. Learning about the history of the Internet along with network attack and defense allows users and anyone operating within the digital

What is the basic internet and how do you make it safe? Most people in the world have a computer but do not know what makes a computer a computer. Most people do not even know what device would qualify as a computer. The computer is an important part of the twenty-first century. The responsibility of computer users goes beyond internet access. The computer has basic internet and security that is needed to be followed. The internet guarantees a source of internet access nevertheless; a computers security is the most important part of being a computer owner or user.
