Denial of service (DoS) attacks have become a major threat to current computer networks. Early DoS attacks were technical games played among underground at- tackers. For example, an attacker might want to get control of an IRC channel via performing DoS attacks against the channel owner. Attackers could get recognition in the underground community via taking down popular web sites. Because easy- to-use DoS tools, such as Trinoo (Dittrich 1999), can be easily downloaded from the
Internet, normal computer users can become DoS attackers as well. They sometime coordinately expressed their views via launching DoS attacks against organizations whose policies they disagreed with. DoS attacks also appeared in illegal actions. Com- panies might use

iPremier, a Seattle based company, was founded in 1996 by two students from Swathmore College. iPremier had become one of a few success web-based commerce, selling luxury, rare, and vintage goods over the Internet. Most of iPremier’s goods sell between fifty and a few hundred dollars, and the customer buys the products online with his or her credit card. iPremier’s competitive advantage is their flexible return policies which allows the customer to thoroughly check out the product and make a decision to keep the product or return it. The majority of iPremier customers are high end, and credit limits are not a problem.

VAH6500 provides a concise policy which states any individuals that access sensitive information or systems must complete annual security training. Key persons with “significant” roles must attend additional training. All training is monitored for completeness. Policy indicates before employees can use systems security training must be completed.
With at least 13 ambush shooting of law enforcement during the last few weeks, Minneapolis police are making changes to how they handle 911 calls. Ambush shootings of officers nationwide were up 50% in 2014 and today's numbers stand at a 70% increase over 2015! Washington-based National Law Enforcement Officers Memorial Fund says ambush-style attacks are the leading method in the surging numbers of shooting deaths of law enforcement officers.
Witness, Cody Inegrigtsen, was driving in the area of 125th PL SE and SE 318th Way, when he noticed a young male, James Richardson, assaulting a young female, Kayla Buss.

It was noticed by police that Kayla and a swollen lower lip and it was observed that she had several small cuts also on her lower lip. Both Kayla, who is 15 years old , and James, who is 16 years
Denial-of-Service (DDoS) attack is the one in which the host’s network elements are flooded with high volume of fabricated attacking packets that originate from a large number of machines . A successful attack allows the attacker to gain access to the host’s machine, allowing stealing of sensitive internal data and possibly cause disruption and denial of service (DoS) in some cases.
The Pakistani government was involved in an attack on Mumbai that killed over one hundred and fifty people. The captured militants who executed the attack were never brought to proper justice, an incarcerated terrorist confessed that Pakistan’s Inter-Services Intelligence agency aided the attack, and the Pakistani government freed the militant group’s commander for no plausible reason. Pakistan has denied all accusations of its’ involvement but evidence shows that they played a key role in this devastating siege.
DNS is critical in the footprinting of a target network. It can sometimes save the attacker a lot of time, or at least corroborate other information that has been gathered. DNS is also a target for several types of attack.
This is the phase of the cyber operation in which the cyberwarriors gather information about potentials targets. This operation can be subdivided in three sub phases. The war planners provides objectives, targeters search for potential target that might achieve the war objectives, intelligence professionals gather information about the target’s weaknesses that might be exploited in an attack (Chapple & Seidl, 2015, p. 5.2).
Denial of Service (DoS) attack is a very common cyber menace that renders websites and other online means inaccessible to intended users. There are various types of DoS threats and nearly all directly target the core server structure. Others abuse weaknesses in application and communication proprieties. DoS is also used as a cover-up for other wicked actions, and to take down security applications like web firewalls. A prosperous DoS attack is very obvious and impacts the entire online user base.
Today, security devices such as Firewall, IDS are used on the many organization's networks for preventing security attacks. But, these devices can only diagnose illegitimate traffic and prevent it. They cannot prevent attacks which are as a result of the network devices vulnerabilities in the switches, routers, and etc. A malicious user who is within the network can implement many attacks by using these vulnerabilities. This paper explains the kind of existing vulnerabilities in Cisco switches and methods of preventing these attacks from
Internet Protocol (IP) datagrams may arrive in a seemingly random order of chunks that the receiving IP entity must continuously collect until it can reconstruct the original datagram. Consider that the receiving IP entity possesses a buffer for assembling the original datagram's data field. The buffer will comprise of chunks of data and "holes" between them corresponding to data not yet received.
