30 April 2015 Introduction There is a growing need to connect to internal networks from locations other than the regular and secure office. Employers and organizations need to realize that employees often need to connect to internal private networks from home, hotels, airports, etc. A solution for this problem is using a virtual private network (VPN), which is a network that uses public network paths, but maintains the security and protection of private networks. Secure communication is expensive, but VPNs allow organizations to have a number of discrete communication services for a large amount of clients. It is cheaper to have a copious amount of virtual networks on a couple physical devices than having a copious amount of physically discrete devices accomplishing the same objective.
Methodology
VPNs transmit data through secure tunneling. A packet is first encapsulated in a new packet with a new header and then sent through the tunnel, which is normally IPSec, L2TP, PPTP, or SSL. Both points of the tunnel need to support the protocol used. To provide access to the internet, the packet with a private IP address can be sent inside of a packet with a global IP address. For security, VPNs use encryption to make sure packets are indecipherable without the proper keys, which provides data confidentiality. They also provide data integrity using a message digest to ensure the information has not been tampered with
A VPN is a private network that uses a public network (usually the Internet) to connect
VPN is the abbreviation of Virtual Private Network. A VPN can extend a private network (like local network) across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus benefit from the functionality, security and management policies of the private network [7].
Which of the following is protocol used to enable communication securely between points on a Virtual Private Network (VPN)?
OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections and remote access facilities. OpenVPN allows authentication using certificates or username/password. OpenVPN can work in two different modes regarding encryption. It can use static encryption or Public Key Infrastructure (PKI). The advantage of static encryption is that it is very easy to configure. The disadvantage of this type setup is that if your encryption key is compromised, all VPN data can easily be decrypted. The PKI mode resolves many of the issues static encryption has. It

VPN refers to the networking technology Virtual Private Network. A VPN allows users connected to this network the ability to access any website or computer data from any location in the world with dedicated and secure networking environment rather than being present in a public server. Majority of VPN users belong to business class industry and educational purposes. VPN networks are used in this manner because majority of VPN networks offer the features like encryption and anonymity which increases the privacy and security benefits while using the VPN network. VPN networks also allow the user ability to perform activities on the internet as if they were accessing

The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.
Virtual Private Networks (VPNs) are used to allow a remote public connection to an internal network. A VPN is essentially a virtual tunnel connecting a remote user (Tunnel Vision). The traffic within the VPN tunnel is encrypted, and there are two ways to do this. One way is Internet Protocol Security (IPsec) and the other is Secure Sockets Layer (SSL).
VPN stands for a Virtual Private Network. It’s a means of connecting computer devices to the internet through data or broadband connection while adding a layer of privacy to what you do online. Virtual private network (VPN), presents excellent control of how you are identified online. VPN generates a virtual encrypted channel between your device and a remote server run by a VPN service. Internet traffic is routed through this channel, so your Internet Service Provider can't see your data. Each packet of data transmitted from your device is put inside another packet. Think of it as inserting a letter into an envelope to prevent its contents from being read during transport. Your computer shows the IP address of the VPN server,
This type of network is designed to provides a secure, encrypted tunnel in which to transmit the data between the remote user and the company network” (Beal). VPN uses encryption to provide data confidentiality. Virtual Private Networks makes use of encryption and special protocols to provide extra security.

One of the biggest debates in sports right now is whether or not college athletes should be paid. They spend an extensive amount of time between classes, workouts, practices, and games. As an NCAA Division III athlete, I can relate to having a demanding schedule. Everybody has to go to their classes and practice every day. In addition, we have skill workouts between classes depending on the day, as well as lifting four days per week in the offseason and two days per week during the season. It is important to keep in mind that the schedule of a Division I athlete would be even more strenuous. On top of that, a school’s athletic teams are the face of the school. For many people, the only
SSL VPN is a newer VPN technology that links an employee’s computer to a corporate network via a web browser. No client software is required, meaning a larger variety of operating systems are potentially supported. The third type of VPN is mobile, in which one of the endpoints of the tunnel is not fixed (Bridwater, 2013).
Imagine sitting in a room. You are strapped tightly to a chair, with an IV jutting out of each of your arms. Your mind is racing, your heart pounding as a saline solution courses through your veins. Your time on Earth is about to end and you prepare yourself for this fate, bracing for the first of three drugs that will end your life. As you turn to look upon your loved ones for a final time, you realize you can’t: the leather straps around your head prevent you from seeing your family members, who stare at you through the small window and wait for you to die. This fate, although fictional for you, is a very real experience for people who die by lethal injection, the most common method of execution for criminals given a death sentence
