Active Attacks
This is in contrast to passive attacks and in such a type of attack the attacker would not just intercept the message, but even modify it. An active attack can be defined as an attack where unauthorized individuals make modifications to messages, data streams or files (Tom Karygiannis, 2002). One of the main reasons for such attacks to be deadly is that even if we can detect them we are not always sure about how to avoid them. Active attacks are follows under this category:
1. Masquerading
In such type an attack an unauthorized, user would pose as a genuine user and would gain access to private information about the organization. In this, the attacker gain access of the system or will have more privileges then they are actually
Organizations who deal with sensitive customer related data should take extreme precautions when transferring data from one location to another and make sure that those transmissions data are secure and under the protection of the authorized user. Since wireless technology is new in the market but has become almost inexpensive, it is gaining more popularity in all type of businesses. The inexpensive device brings the threat of security into the system and it becomes of utmost importance that no information leak happens in any form. The strength of a computer system’s security is always measured by its weakest component (Loo, 2008). Thus all the users should be given appropriate training on how to use secure their data when they are at home or at the corporate premises. A combined effort of users, employers and system administrators is required in order to fight against such malicious activities. Appropriate countermeasures in every form can help the organization minimize the risk of illegal penetration. Up to date tools, constant monitoring, proper management and appropriate countermeasures are all the ultimate weapons to fight against the wireless security
In today’s society the word “terrorism” has gone global. We see this term on television, in magazines and even from other people speaking of it. In their essay “Controlling Irrational Fears After 9/11”, published in 2002, Clark R. Chapman and Alan W. Harris argue that the reaction of the American officials, people and the media after the attacks of 9/11 was completely irrational due to the simple fact of fear. Chapman and Harris jump right into dismembering the irrational argument, often experienced with relationships and our personal analysis. They express how this argument came about from the terrorist being able to succeed in “achieving one major goal, which was spreading fear” among the American people (Chapman & Harris, para.1). The supporters of the irrational reaction argument state that because “Americans unwittingly cooperated with the terrorist in achieving the major goal”, the result was a widespread of disrupted lives of the Americans and if this reaction had been more rational then there would have been “less disruption in the lives of our citizens” (Chapman & Harris, para. 1).
At 2.40pm on Friday 21st July 1972, the first bomb planted by the Provisional Irish Republican Army (PIRA) exploded outside Ulster Bank in Limestone Road, Belfast (BBC, undated). Over the next ninety minutes, 18 more bombs exploded around the city, whilst a further 2 were defused and 2 failed to detonate. In total, 9 people were killed, including 7 civilians, and 130 were injured in the attack that later became known as ‘Bloody Friday’ (BBC, undated). The PIRA were a republican paramilitary group that sought to end British rule in Northern Ireland during a period known as The Troubles after the British Army was drafted in to help with rioting between nationalists and unionists in 1969. As nationalists, the PIRA believed that the ‘Six Counties’
The integrated threat theory model consists of four types of threats that can lead to prejudice. These threats are: realistic threats, symbolic threats, intergroup anxiety, and negative stereotypes. Realistic threats are posed by the outgroup and have several types of consequence and impact. They can either be threats of war, threats to political and/or economic power of the ingroup, and threats to physical and/or material well-being of the ingroup and its members. Symbolic threats is usually based on perceived group differences in morals, values, standards, beliefs, and attitudes. Symbolic threats are also threats to the ingroup’s worldview and these threats arise because the ingroup believes that its system of values are morally correct.
The Attack on Pearl Harbor was a shocking blow to the United States that forced the U.S. into World War II. The United States goal was to stay isolated from foreign affairs, but Pearl Harbor changed all that, forcing them to get involved in foreign affairs. A young, power hungry United States wanted to control Southeast Asia, angering Japan along the way. The reason the Japanese attacked Pearl Harbor was the results of decades of tension starting back in 1899 with arguments over the United States Open Door Policy; both countries desired control over the Pacific and East Asia, which made war unavoidable.

Pearl Harbor was a very vicious attack by the Japanese on the US. On December 7, 1941 US Pearl Harbor was attacked by Japanese fighter jets. United States had been aware of a possible attack since the 1920s; the US became more involved when the Japanese invaded Manchuria. Attack on Pearl Harbor was the beginning of something big, a bloody war between the Japanese and the United States. United States was not expecting such an event; it was such an unannounced attack on the naval base in Pearl Harbor, Hawaii. That unexpected attack on December 7, 1941 was originally just a preventive effort for keeping the US from interfering with military action the Empire of Japan was planning in Southeast Asia. Japan wanted to cripple the pacific fleet so they wouldn’t foil their plan to create a defense perimeter in the Southwest Pacific. Japanese aircraft launched two aerial attack waves sinking four US Navy battleships and damaging two other battleships. The attacks also led to a high number of deaths. There original plan was to attack all of the US aircraft carriers. The attack on Pearl Harbor resulted in US entry into World War 2.

This is only a small part of the prevention of infiltration of your network and computer. If one desires to learn more, go above and beyond and continue to learn on how to keep your network secure.
This proposal is for a small office that will have users who are connected by Wi-Fi or cable. The network will include devices and resources that is shared among all the users. The network will need to have security measures in place to protect the entire network and keep the wireless access secure and available only to employees of the company.
While the conventional desktop PC will still continue to serve important functions at both consumer and professional levels, there is an expectation that mobile devices will become the predominant form for accessing both personal and professional content; it is understandable that cyber criminals have begun focusing on mobile devices which have at the same time grown their user base while substantially consolidating the operating system variants which makes the surface area for a potential attack substantially larger (Juniper Networks, n.d.).... ... middle of paper ... ...

Andrew Massung Mr. Wyse ENC 1101 15 October 2015 Cyber Warfare: the New Frontier Since the beginning of time, mankind has waged war against each other. Over the years, warfare has evolved, from fighting with sticks and stones to using gunpowder and launching missiles. The newest, and possibly most destructive, type of warfare is cyber warfare. Cyber warfare has the potential to be more devastating than nuclear warfare.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
Properly secure wireless systems: - To prevent data breaches it is very important to secure wireless networks. WI- Fi network security is necessary because it is very easy to hack the data and unauthorized access. Breaches can be prevented by using strong passwords, encryption methods, and strong verification.
The book is structured into four parts: Part 1 discusses the fundamentals of Internet security and privacy, Part 2 specializes in privacy while on the World Wide Web, Part 3’s topics are e-mail security and privacy, and Part 4 discusses the ways in which to secure a computer. Following the structure of the book, I will review and summarize the most important aspects of the parts and chapters in chronological order.
