SUBJECT: Expanded Definition of Virtual Private Network (VPN)

Introduction

The scientific term I selected for this expanded definition project is VPN, which is an acronym for Virtual Private Network. Below is a summary of my findings and the knowledge I have gained from researching this term. I will be discussing the various definitions and components I have discovered online through journal articles, encyclopedias and other relevant sources.

Definitions

According to Britannica, the official definition of a Virtual Private Network is “a private computer network deployed over a public telecommunications network, such as the Internet. A VPN typically includes one or more connected corporate intranets, or local area networks (LANs), which users at remote locations can access using a password authentication system” (Britannica, 2016). In simpler terms, VPN’s are systems that permit public internet networks to be utilized as private networks with the purpose of increasing security. It provides more privacy and a secure connection within a public network. When you are in a public place such as a cafĂ© or a library, you most likely would want to use their public Wi-Fi network to access the internet. However, this is not safe due to the fact that the information from your device will then be accessible by everyone else using the same Wi-Fi network. That is where VPN comes into play with providing an extra layer of security. You will still be able to access the internet with the public Wi-Fi, but will be safeguarded by the Virtual Private Network. Based on the Network Encyclopedia, “VPNs use tunneling technologies to allow users to access private network resources through the Internet or another public network. Users enjoy the same security and features formerly available only in their private networks” (Editor, 2020). This emphasizes that with a VPN, there is much more security and is the safer option when it comes to surfing the web through a public connection.

Context

Back in 1996, employees working for Microsoft Corporation created a procedure called PPTP, which stands for point-to-point tunneling protocol. It was a system of designing a protected network between users through encoding data and establishing a tunnel over local area network (LAN) or wide area network (WAN) connections. This procedure allows the transfer of confidential and significant data securely, even within public networks. The only thing needed to send and receive secured information through PPTP is a username, password and an IP address. Due to these simple requirements, PPTP has continued to be one of the most popular types of VPN. Originally, VPN’s were utilized by big corporations but throughout the years, internet users have become more alert to the probability of threats with working online and have started discovering more secure ways of using the internet. Nowadays, VPN’s are being used by many people to safely access the internet, avoid being hacked, prevent viruses from entering their technological devices and finally, ensuring online privacy.

According to Mujović, the purpose of a VPN is “to create a private connection between multiple people and devices across the Internet. In effect it is an Internet within an Internet, secure private and encrypted from prying eyes, malware, hackers and anyone else who may wish to know where you surf, or where you are surfing from” (Mujović, 2018). This actively demonstrates the importance of using a VPN when you are accessing a public network. It can protect your personal data and sensitive information from being stolen by cybercriminals. The term VPN is also discussed in context to multiprotocol label switching in a journal article. The writer states “a network in which customer connectivity amongst multiple sites is deployed on a shared infrastructure, that utilizes the same security, management, and quality of service policies that are applied in a private network” (Azher et al, 2005). The article provides an overview of the multiprotocol label switching VPN technology services and how it relates to other types of VPN. It highlights the problems linked to delivering VPN services in a MPLS setting.

Working Definition

The scientific term Virtual Private Network directly correlates to my major in Networking & Security because of how and why it was initially created. To sum up everything that has been stated so far, VPNs were formed to protect users from getting their data stolen by unauthorized individuals also known as “hackers” or “cybercriminals.” With a VPN, all your data is directed through an encrypted cybernetic tunnel. By this, your IP address is unknown when using public networks, making its location hidden to everyone. Cybersecurity continues to be a developing field due to the advancement and use of technology within our generation. With the help of VPNs, your data can now be safe and protected.

Summary of Dixon Jr.’s “Artificial Intelligence: Benefits and Unknown Risks”

SUBJECT: 500-Word Summary of Article About Artificial Intelligence  

The following is a 500-word summary of a journal article about the benefits of artificial intelligence as well as unknown risks in context of the judicial system. The author highlights that AI is a technological advancement that has substantially influenced the world of law and criminal justice. He also emphasizes that there have been a few AI inaccuracies which have caused red flags in the past. The article focuses on artificial intelligence related to eDiscovery, predictive policing, crime solving, risk assessment and the judicial use of AI in court cases. It also indicates the development of AI facial recognition software to identify prime suspects and criminals. Artificial Intelligence has been a great help to society and its people however, there are many risk factors that have not yet been officially acknowledged.

AI has the ability to be efficient and effective with resources to decrease the work of manual laborers as well as increase the comfort of people’s lives.AI has made a significant impact in the world of law enforcement by assisting them with facial recognition and crime prediction algorithms. With the help of AI, police officers have had an easier time to recognize suspected criminals and also calculate the possibility of a perpetrator committing a crime once again. Additionally, Al-based facial recognition software has been employed to identify suspects from images caught on security cameras, cell phones, and other video sources (Dixon 2021). Law enforcement agencies use Predpol, which is an AI algorithm that contributes in foreseeing crimes for certain areas on a daily basis. Researchers are also introducing algorithms to determine class of weapons based on gunshot audio.These algorithms will be able torecreate crime scenes by using certain data to help investigators improve their understanding of an event.COMPAS is an AI driven assessment tool to reassess defendants in criminal cases.

In recent events, the Department of Justice discovered repetitive law violations by the police regarding the use of extreme force against Black people, minority groups and failing to report women violence issues. Evidence indicates that the developers of the algorithm did not provide accurate historical data. Supporters of AI think that this is the only way to decrease human error and bias in official courts. However, studies show that AI has actually revealed bias in the past, mistakenly claiming Black defendants as potential criminals more than white defendants. There was a study conducted in 2017, where they recruited volunteers online, asking them to predict whether certain individuals are likely to repeat a crime. The crowdsourced predictions were as precise as COMPAS at predicting repeated offenders. Although AI algorithms are great at recognizing consistency in data and are able to generate predictable results, consistency and predictions are not the same as being fair. Technologies and machines struggle to operate in a world where biases and prejudices exist. Overall, AI plays an important increasing role in our lives and the criminal justice system. However, it can sometimes do more harm than good and we as a society need to re-evaluate the uses of AI.
