The Advantage of VPN Security and Design

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).

Versa VPN is working as VPN vendor since 2010 to facilitate the users with secure and anonymous browsing. They provide an above average service to their clients with their business philosophy to deliver the best internet security with finest levels of quality keeping it within the reach of common internet users. Versa VPN suppliers maintain its quality and make sure it users’ end by restricting 20 number of clients at each server. They are providing best customer care support through different methods including email address, telephone number, ticket support, Twitter account, and Live Chat option. They also ensure a reply to every query within 30 minutes.

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].

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.

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.

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

A VPN offers mobility and security for remote workers. The VPN uses an encrypted connection using the Internet. Remote workers wanting to use the Internet file server need authenticate their identity with a login id, password, RSA token, or smart card. The VPN can be used on company-owned laptops and personal electronic devices (PEDs). The VPN works by using data encapsulation. Encapsulating data packets into another set of data packets and data header this is the ‘tunnel’ used to send private data through the Internet. The data reaches its destination where the data is extracted from the 'tunnel'. It is then sent to the Application Layer where the remote worker can view or retrieve the files. This is a dedicated connection between the company and the remote worker computer. It is failsafe; the data sent through the VPN is encrypted by the sender and decrypted by the receiver. This prevents the data from being altered, read, or stolen by a hacker. Different cryptographic rules on each layer of the OSI model provide secure data transmission, authentication, confidentiality, and nonrepudiation. The cryptographic tunneling rules implemented for data security in each of the OSI layers (starting with the bottom layer) are listed

The company can invest in research and development for the sole goal of understands the Virtual private network (VPN). This will help and give them extensive knowledge about problem that might arise for this investment. Virtual private network (VPN) is a tool to protect privacy and security while people use the internet. This specific network type has the ability to unblock any restriction and for the company can help customers access contents from different countries example customers in the united state can view contents from Canadian or European Netflix and vice versa.

Nowadays most people have heard of a VPN or virtual private network, but outside of the workplace, many people are not using them. However, it is highly recommended that many people should use them or at least consider using them in the future as they are so useful.

To secure remote connections, a virtual private network (VPN) will created using the Routing and Remote Access feature available within Windows Server 2012 R2. This feature allows end users to create a secure connection to the network by using Extensible Authentication Protocol-Transport Level Security (EAP-TLS) in addition to smartcards for authentication purposes. Traffic will also be encrypted by using Layer Two Tunneling Protocol over IPSEC (TechNet, 2016).

Today, the technology VPN (Virtual Private Network) has established strong recognition among IT people and every administrator is committed to organize VPN-channels for employees working outside the office.

The primary aim of this project is to keep VPN safe which also means keeping our information and credentials safe.As of now the working principle and the protocols related to VPN i.e Virtual private network is understood.VPN is considered to be invisible and impenetrable by most of its users and the organizations providing this service till date but the research carried on by NTA monitor Ltd. shows that these VPN 's are the weakest point in their perimeter.VPN 's are the most attractive targets for the hackers. There are many flaws in VPN services which can give a hacker, a lot of information about the users of VPN.Virtual Private Networks carries themuch sensitive information over an insecure network. Most of the users believe VPN 's keep their information secure that is what VPN 's are there in market but its is shocking that VPN 's also have remote exploitable vulnerabilities through which one can gain an unauthorized access to the Network or can alter the traffic in the Network etc.

VPN are extremely regular utilized technique nowadays as a part of companies where they need to keep communicate with their unreachable branches at some point in other piece of globe. It permits authorization to get to companies Intranet in a protected and effective way.
