Defining VPN in Computer Networking
The purpose of this paper is to provide a definition and explanation of a virtual private network (VPN) which is a key concept in information technology (security and network technologies). The explanation that follows includes selected quotes to provide some definitional clarity of the term and the key concepts that are involved as well as the different types of VPNs and how they are related to other relevant concepts. Finally, a description of an example based on this writers empirical experiences with VPNs is followed by a summary of the research and important findings concerning these issues in the conclusion.
Two different definitions of VPN and commentary concerning how it is defined, highlighting the key concepts involved
Although there is no universally agreed upon definition, the cybersecurity experts at Kaspersky define a VPN as a protected network connection when using public networks [which] encrypt your internet traffic and disguise your online identity [making] it more difficult for third parties to track your activities online and steal data (What is a VPN?, 2022, para. 3). By contrast, Cisco defines VPNs as an encrypted connection over the Internet from a device to a network [which] helps ensure that sensitive...…be blocked from access otherwise. For instance, users in the United States may not be able to access Web sites in the UK and vice versa, but a VPN allows them to gain such access by changing their country of origin.
Conclusion
There was a high degree of congruence between the above-cited definitions of VPN, differing only in their respective descriptions of its various features and their relative importance for users. The research also showed that VPNs are related to other concepts such as encryption, data security and data collection. Finally, VPNs were shown to be significant for information security based on their ability to encrypt…

The operating system faced these issues due to the lackluster approach from Apple to patch their software in time. As a result, it led to risking the data of personal users. It shows that irregularities in the patching of computers affected users adversely without any fault of their own (Daily Tech, 2012). In addition to that, the operating system of Apple is now considered as one of the most favored

Cybersecurity as an Organizational Strategy: An Ethical and Legal Perspective Cybersecurity as Organizational Strategy Across the board -- in business, society, and government -- the promise of cyber capabilities are matched by potential peril. The cyber environment is never static, but it is perhaps most agile in response to the continual stream of emerging cyber threats and realized cyber attacks ("PCAST," 2007). Cybersecurity must be agile. The challenges that must be met

Hardware attacks because of Vulnerabilities Hardware Data modification / injection The Scientist Argument Secure Coprocessing How organizations can best address its potential impacts Cybersecurity Vulnerability: Hardware Weakness This essay introduces the role that computer hardware weakness opens the door up for attack in cyber-physical systems. Hardware security -- whether for attack or defense -- is not the same as software, network, and data security on account of the nature of hardware. Regularly, hardware
The level and sophistication of this attack on the Department of Defense's systems suggests that professionals conducted this attack with significant resources at their disposal and an interest in the national security secrets of the United States. The data mining operation was so successful that, while detected, still managed to make-off with a significant amount of information. Since the attack, the United States responded in a number of critical ways.
Cyber Security Ethical issues associated with ransomware It is only natural that people who are known to you will send you messages through your email address. It is lost on me how those engaging in ransomware business access information about their potential victims like the email address as to send you messages that have been infected that when opened infect the whole computer. These people engage in irregular activities. For the residents
