This includes hosts file poisoning, even though the hosts file is not properly part of the Domain Name System. Hosts file poisoning is discussed in the malware section since it involves changing a file on the user’s computer [14]. j) Content-Injection Phishing Describes the situation where hackers replace part of the content of a legitimate site with false content designed to mislead or misdirect the user into giving up their confidential information to the hacker. For example, hackers may insert malicious code to log user's credentials or an overlay which can secretly collect information and deliver it to the hacker's phishing server. k) Man-in-the-Middle Phishing This is harder to detect than many other forms of phishing.
Case Study For any business ping sweeps and port scans could be a huge security threat if they continue unnoticed. Ping sweeps are performed to find end points on a network. Then a port scan is performed to find an open door into that particular end point or end points. After that anyone can find all kinds of utilities on the internet to exploit these open doors on systems and gain access to important and confidential files on the network. It’s imperative that we not only protect against these types of activities on the network, but that we also conduct them ourselves.
For individuals and organisations these malicious programs can collect authentication data such as account details and passwords which can be later used for cybercrime or hacking. • Spyware: software that covertly transmits data about the activities a user is performing on their system. Spyware can also be used to install additional software, redirect browser searches, change computer settings or disrupt network connections. Typically, spyware is installed during the installation of a piece of free software. • Phishing: is the act of sending emails purportedly from a reputable company in order to trick a user into revealing personal information such as passwords and account details which will be later used for cybercrime.
d. denial-of-service attack (an example: smurf attack) 4.

For my paper, I will further assess how often privacy is invaded with technological devices and how different people use this information. How can it harm society and are there any uses for this invasion of privacy. I will also look at how common it happens and assess, based on several occasions, how they have been useful or detrimental for people. I hope to further understand how technological devices can be easily used as a tool to invade people’s privacy through social media and technology and further assess whether it has any benefits. Methods First, I will approach the several ways of how technology can be used to invade privacy.
Whether you’ve been a victim of cyberbullying or know someone who has been cyberbullied, there are steps you and your friends can take to stop cyberbullying and stay cyber-safe. How are people cyberbullied? Cyberbullying occurs when an individual uses the Internet or another form of technology to harm other people, in a deliberate, repeated, and hostile manner. In some cases a person may pretend that they are another person online to trick others. They could spread lies and rumors about victims, trick people into revealing personal information, send or forward mean text messages, and post pictures of victims without their consent.
Software devices used are; firewalls, Host intrusion Prevention Systems (HIPS), and Antivirus/Malware scanners. The concept of “work factor” is an important part of layering and is defined as the amount of effort a hacker, malware, etc. must use to breach the security measures guarding our network. Obviously, the less work they have to do point out that our security isn’t good. Showing that we have strong, layered security around our data and network will convince them to go elsewhere.
According to McFadden, “a whole market of programs has emerged that allows companies to secretly record everything a person does with his or her computer.” In the past and present, employees believe that it’s acceptable to use their company’s computers to look at porn, participate in social networking, and send instant messages to friends. These activities should be done on the employees own leisure time. Employers like the security of knowing if their employees are taking part in things that are incongruous. The employers also like knowing if their employees are getting their work done. These spyware programs are the only way for the employer to know what is going on while the employee is on the company computer.
