Introduction
In this report I will be describing the ways in which networks can be attacked, also be giving real life example of each of the below.
Denial of service – Denial of service or DOS is an attempt to make a machine or network unavailable to its users. The services that were available to the user wouldn’t be available anymore. Although the result of a DOS attack does not lead to data theft. However a great deal of time and money can cost the company. An example of a service being stopped is email, or can be a loss of network connectivity. There could be no access to shared storage and no one would be able to access the internet while the DOS attack.
The most common type of DOS attack is ending traffic to a network address. This will cause the network to slow down. The attacker must already know a weakness of some sort on the network, or the attacker just goes

There is another type of spoofing like email spoofing. Email spoofing is when the message appears to be from someone trusted but in an actual fact it’s not. People who distribute spam tend to use email spoofing to make you open it and respond to them. Spoofing someone in any way is illegal. It is against the law. To get round this you can delete all your spam as there is a risk there is some kind of spoofing waiting to be open. Also delete any email that is useless and do not give your email to anyone as they can send a lot of spam to your email.
Rootkit – Rootkit is a software that is downloaded onto a computer to ide the compromised operating system. This can allow other viruses or malware to come and make it look like it’s a necessary file for the computer. Even if you use an anti-virus, it will look at it but will think it’s a necessary file for the computer. The longer the rootkit is installed the harder it is to undo the damages
In the UK, it is a must to follow the law of equality whilst employing any person for the job, according to section 159, positive action: Recruitment and selection of equality and anti-discrimination law (Butler, 2016). Therefore, according to this law if a person is having similar qualities and qualifications required as per the job description, is already working with the organisation, the organisation cannot recruit the person from outside and decline the promotion to the employee. If in the Debenhams department store there are more than one employee, who are experienced and eligible for the post of floor manager; it would be unethical and illegal to promote one employee over the other employee. Therefore, an organisation needs to make all
The client in this report is Richard Potter. He is a London Black Cab Driver, he was chosen as the client due to the fact he would use the application on a daily basis because his current Taxi Cab does not include a built-in trip computer as standard and one would be helpful to him while at work to give him useful information about his journeys and the vehicle, which he relies on to produce any sort of salary since he is self-employed. His job consists of making journeys of varying lengths between destinations across London and the surrounding boroughs, occasionally on longer journeys outside of the capital such as to Stansted or Gatwick Airport. The application would be built with him in mind, meaning it must be easy and quick to

LAND DOS attacks: Local Area Network Denial attack is a DoS attack in which a special poison spoofed packet in send to a computer, causing it to lock up itself in a loop.
The business could provide employees with a peg or a proper coat hanger which is safer and better for the business. This also has less chance of a hazard occurring, the manager should also provide the employees with cupboards or lockers for employees to put their personal things in, this is
In this report I will be explaining the different legal and ethical procedures that employees at Leyton Sixth Form must follow. By doing this I will be discussing the data protection legislation, codes of practice and operational issues. I will be linking it back to how Leyton Sixth Form College uses this information and how they respond to a staff member breaking that act.
We should have the contract completed fairly soon. At this point, I am waiting a response from the Buyer's representative as to whether the Buyer wants to make the necessary changes and insert the initials manually or allow me to insert the correct information on the contract and let the Buyer digitally execute it on-line for a matter of convenience.

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.
In Denial of Service access to network applications or data is denied to intended users. Denial of Service may be invoked through many techniques. The most common technique is overload of server resources such as memory and CPU by flooding the network with database queries that ultimately cause the server to crash
Additionally, some malware creates a denial of service by design, increasing the possibility of an attack on the organization’s infrastructure. While most organizations understand denial of service very well since it impacts productivity but many ignore the impact on confidentiality and integrity. Attackers access the organization’s data they can use this to sell to third parties and make a profit.
One of the ways in which cyber criminals like to operate is by causing an interruption of service which can cause significant damage to all those effected. When a network comes to a screeching halt, so do all of the services that corporation or organization provides.
Denial of Service (DOS) or Distributed Denial of Service (DDOS) is one of the biggest security risks in cloud computing as well as any other internet based services. DOS or DDOS generally functions by the attacker sending large amounts of data packets, such as simple TCP/UDP or really any other
DISTRIBUTED DENIAL OF SERVICE (DDoS) Prachi Shah School of Informatics and Computing Indiana University Bloomington Email: pracshah@indiana.edu Abstract--- Distributed Denial of Service attacks are executed by an attacker that uses numerous zombie machines to launch an attack against the victim system. The purpose is to exhaust the connection bandwidth thereby, making a network resource or a service temporarily or indefinitely unavailable to its intended users. Keywords DoS, DDoS, bandwidth, networks, zombie, botnet 1. INTRODUCTION 1.1 Computer Security and Privacy One of the most challenging and important issues faced in the computer networks domain since a very long time now are network security and privacy issues.
The next form of DoS attack is the ICMP flood which has an end goal of utilizing all of the allocated bandwidth for the target machine. (Tixteco, L., Aguirre, E., Hdez, M., & Ruben, G. 2012) Typically an ICMP is used for error detection when the destination for IP packets is unreachable. (Kaushik and Joshi, 2010) an ICMP flood attack takes advantage of this process by sending a large amount of ICMP packets to the target which requires a response from the target. Once these responses reach a certain threshold there is no longer any more bandwidth that can be utilize, leaving the target incapable of handling anymore request. (Tixteco, L., Aguirre, E., Hdez, M., & Ruben, G. 2012)
