Virtual private networks (VPN) provide an encrypted connection between distributed sites over a public network (e.g., the Internet). By contrast, a private network uses dedicated circuits and possibly encryption. The basic idea is to provide an encrypted IP tunnel through the Internet that permits distributed sites to communicate securely. VPN 's permit secure, encrypted connections between a company 's private network and remote users through a third-party service provider. A VPN can grow to accommodate more users and different locations much easier than a leased line. In fact, scalability is a major advantage that VPN 's have over typical leased lines (dedicated circuits). Unlike with leased lines, where the cost increases in proportion …show more content…
With RAS you would need access to the actual wire or the telephone switch being utilized and VPN 's utilize a lot of different devices when crossing the internet making it more susceptible to hacking. When purchasing a VPN for your company one of the first things that you need to decide is what type of protocol you would like to use. One of the more common protocols used is the Point-to-Point Tunneling Protocol (PPTP). PPTP is a protocol that is used to allow users to connect to their corporate network via the internet. This is a relatively inexpensive way to provide remote access to your network considering that most Microsoft operating systems come with some sort of PPTP client. Other things to keep in mind when coming up with a VPN solution are the implementation and design and the cost of the solution. The cost is especially important considering that the uses of VPN 's are used to help save your company money. There are four types of attacks used against VPN 's. Those four types are impersonation, integrity, disclosure, and denial of service. Impersonation attacks are used just as the word says; it is when someone tries to get into your network while posing as someone else. This type of attack can be greatly reduced by using the strong authentication methods supported by PPTP. Integrity attacks are the changing of information during a transfer of data. The most common integrity attacks take place on email messages where a hacker
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).
As hacking and attack in the personal network connections is increasing day by day, it is needed to adopt a technology that will protect the network and have the facilities to stay connected
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

4. Pg 319 VPN. A virtual private network. It’s a type of outsourcing. They use privacy techniques such as tunneling.
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
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].
2.. Security standards: When working mobile, one is dependent on public networks, requiring careful use of VPN. Security is a major concern while concerning the mobile computing standards on the fleet. One can easily attack the VPN through a huge number of networks interconnected through the line.
Remote access must be strictly controlled. Remote access allows authorized users to access network resources as if they were at the physical location of the company network. These connections may be made over the phone lines by directly dialing into a remote access server on the network, or they may be made by virtual private networking (VPN).The VPN server will support Layer 2 Tunneling Protocol (L2TP) tunneling with Internet Protocol Security (IPSec) encryption. Dial-in remote access uses modems, servers running the Routing and Remote Access (RRAS) service, and the Point-to-Point (PPP) protocol to enable remote users to access the network.
The most secure networks are those that incorporate a virtual area network. This allows updating of information by employees and approvals or verification of those updates by authorized personnel. Access to this information calls for password and username protection by way of 128-bit encryption standards. If further, more detailed information would need updating or change, an authorized person will be required to input their information, including fingerprints. This is called multi factor authentication.

It is crucial to employ the best VPN service because of the issues related to the internet security that persists today. This ensures that your personal and business information do not get maliciously distributed or hacked. With a plethora of options available, it becomes difficult to pick the best VPN service available out there. There are certain parameters that you need to consider while looking for having VPN services.
A VPN is a secure protected network called a tunnel for communication purposes over long distances using the Internet as its means of transport. Due to the nature of the communication or transmissions that are being utilized by say a larger corporation, secure and reliable communication is a must. In the beginning these VPN connections were established using one or more dial up modems for users to access the information. Authentication was established by requiring the correct user name and password. As time went on as always things changed, new technology and advances in communication as well as equipment allowed the VPN to evolve and expand. To ensure security, the virtual tunnel is encrypted. VPNs use several protocols in order to encrypt
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).
