Denial-of-service attack Essays

bank accounts from a large denial of service attack. This poses a clear issue to the United States infrastructure which could lead to identity theft of bank information as well as other critical infrastructure being targeted as a result from this successful attack. Beyond losing the access to the accounts of the citizens of the United States, the general view of the United States government could become compromised with the people becoming angered as a result of this attack. The next steps are the most

According to Whitman (2012) “In a denial-of-service (DoS) attack, the attacker sends a large number of connection or information requests to a target. So many requests are made that the target system becomes overloaded and cannot respond to legitimate requests for service.” (P.67). The system could crash or basically become unable to perform normal functions. Most DoS attacks are led by a planning phase in which many systems, perhaps thousands, are compromised. The compromised machines are turned

Rogue DNS servers pose a threat to the Internet community because the information these servers contain may not be trustworthy [SPAF]. They facilitate attack techniques such as host name spoofing and DNS spoofing. Host name spoofing is a specific technique used with PTR records. It differs slightly from most DNS spoofing techniques in that all the transactions that transpire are legitimate according to the DNS protocol while this is not necessarily the case for other types of DNS spoofing. With host

The operation was code name Buckshot Yankee. Operation Buckshot Yankee was the United States response to the terrorist attacks of 2008. Unlike the terrorists’ attack on 9/11, the attack on 2008 was a cyber-attack that affected the U.S Government’s unclassified and classified computer networks. The Deputy Secretary of Defense William J. Lynn III (2010) stated “It was a network administrator 's worst fear: a rogue program operating silently, poised to deliver operational plans into the hands of an

a series of highly publicized DDoS (denial-of-service) attacks in February 2000 while he was a student in High School. These attacks targeted large commercial websites including: Dell, eBay, Yahoo!, Fifa.com, Amazon.com, and CNN. He also attempted to launch a series of simultaneous attacks against nine of the thirteen root name servers. Mafiaboy was caught because he had been bragging Internet chat room about his actions and left traces of evidence on the attack. Back in the 1970s and 1980s, hackers

internet traffic became a victim of a massive DDoS attack. Although it is uncertain who was behind the DDoS attack, security experts are certain that a program called Mirai was used to initiate the DDoS attack on Dyn (Blumenthal & Weise, 2016). Because of the DDoS attack, some users were not able to access their social media, entertainment, music, and other sites such as Twitter, Reddit, Amazon, Tumblr, Netflix, PayPal, and many other sites. The attack started at around 7 am, when Dyn released a message

unauthorized access or outside attacks. The well-executed and implemented defense in depth strategy prevents an extensive variety of attacks and produces real-time intrusions alerts to the administrators. The defense in depth strategy also provides differential security against attempts from attackers who decide to exploit real-time environments with different tactics of attack. Defense of depth creates an effective way of validating and prevention of automatic attacks from the public internet against

In general, passive attacks tend to strike at the confidentiality of information and data systems. For example, traffic analysis is an attempt to eavesdrop on private data, thus compromising the information’s confidentiality. In contrast, active attacks are designed to alter data, or deny service to a network or information system, compromising the integrity or availability of that system. Both replay and modification of message attacks alter data before forwarding it as legitimate

Information security is claimed to be a management problem in some aspects. Many businesses and government managers drift away from information security because, they portray it to be a complex task that's out of their reach. Information security is not 100% based on just technology alone, but rather than management itself. Many managers believe that more technology is the solution to technology problems, but that's far from the truth. Management has certain abilities that technology can't do for

private institutions. They recognize the terrible impacts with the cyber attacks. At present, cyber attacks has resulted in computer based criminal activities which are generating worldwide threat, destruction and disruption. There is no cross border for cyber activities and the increase in the use of internet by the world wide users and lack of international cyber legal regime resulting the increase of the international cyber attacks. Cyber security involves preventative methods which are used to protect

1984. An IDS provides real-time detection of certain types of attacks while they are in progress. This detection allows network professionals to more quickly mitigate the negative impact of these attacks on network devices and users. In the late 1990s, the intrusion prevention system or sensor (IPS) began to replace the IDS solution. IPS devices enable the detection of malicious activity and have the ability to automatically block the attack in real-time. In addition to IDS and IPS solutions, firewalls

Cyber-attack is defined any type of offensive maneuver employed by individuals or whole organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system (Wikipedia,2013). In today’s world, due to unlimited data flow and numerous internet users, cyber-attacks h ave

Hacktivism The world is full of brilliant minds. Because of people’s fascination in discovering new things and ideas, technology is given birth. From then one, the ways of humanity has changed. One of the results brought about by technology is the existence of computers. Computers are now regarded as a necessity because of its various functions. For one, it makes the lives of the students easier because computers are used in making education more interesting. Also, offices use computers to store

or personal) (Blosenhauer, 2014). As we know that, image is possible a very important concern nowadays. Thus, when reputation is threatened especially during crisis happens, individuals and organizations are encouraged to justify themselves to the attack. Organization works on effort to ensure that crises are anticipated, managed, and evaluated effectively and efficiency before any unfavorable impression is formed. Then, here comes a theory used as communication approach to restore the organization’s

data [1]. Based on the 2015 Data Breach Investigation Report by Verizon, 2014 data breach causes by POS Intrusion (28.5%), Crime ware (18.8%), cyber-espionage (18%), insider misuse (10.6%), web app attacks (9.4%), miscellaneous errors (8.1%), physical theft/loss (3.3%) card-skimmer (3.1%), DOS attack (0.1%) [2]. Vulnerability is a hole or weakness that will cause harm and damage to the organization. Cloud computing means sharing resources via Internet and only allow authenticate user to access.

threats continue to plague governments and businesses around the world. Cyberwarfare is Internet-based conflict involving politically motivated attacks on information and information systems. Normally there are two purposes of Cyberwarfare, espionage or sabotage. Cyberwarfare attacks can disable official websites and networks, disrupt or disable essential services, steal or alter classified data, and cripple financial systems. Cyber operations can also aide military operations, such as intelligence gathering

syndicates are taking advantage of the internet to create new business models that facilitate criminal activities on the internet. One of these is the 'Crime-as-a-Service' business model identified by iOCTA, this is a service-based criminal industry, in which specialists in the virtual underground economy develop products and services for use by other criminals (Manky, 2013). The iOCTA report highlights that, as a consequence, entry barriers into cybercrime are being lowered, allowing those lacking

The advancements in information technology (IT) have raised concerns about the risks to data associated with weak IT security, including vulnerability to viruses, malware, attacks and compromise of network systems and services. Inadequate IT security may result in compromised confidentiality, integrity, and availability of the data due to unauthorized access. It is important to ensure the individual privacy remains carefully protected and secured. What is information security threat? A threat is

counter-hack another’s computer would go against half of the listed ethical principles. Further complicating things is the way most internet attacks work. For example, a Distributed Denial of Service (DDoS) uses the resources of generally unknowingly compromised systems. In a hypothetical scenario, a skilled hacker could use the resources of Amazon’s servers to attack another U.S. company’s servers (Himma

The company was experiencing a denial of service (DOS) attack. Smith decided to alert the operations manager Brian of the attack, after he had informed the lead technician. In the midst of the attack, Smith proceeded to also alert the Vice President of Business of the attack. Before Brian could prepare to follow the company’s emergency protocol, or lack thereof, the VP of Business, Chief Financial Officer
