What is VPN And How does a virtual private network (VPN) work?
A VPN (Virtual Private Network) is an encrypted connection over the Internet from a device to a network. The encrypted connection helps to ensure that the sensitive data is safely transmitted. It prevents uncertified people from eavesdropping on the traffic and allows the user to conduct work remotely. VPN technology is widely used in corporate environments.
A VPN (Virtual Private Network) is a connection method which is used to add security and privacy to private and public networks, like WiFi Hotspots and the Internet. Virtual Private Networks are mostly used by corporations in order to protect sensitive data. However, using a personal VPN (Virtual Private Network) is increasingly and becoming most popular as more interactions that were previously face-to-face transition to the Internet.
Today, Privacy is increased with a Virtual Private Network because the user’s initial IP address is replaced with one from the Virtual Private Network provider. Subscribers can get an IP address from any gateway city the VPN service provider.
For instance, you may live in California, but with a use of Virtual Private Network, you can appear to live in Nepal, London, or any number of gateway countries.
How The VPN Works.
A Virtual Private Network extends a corporate network through encrypted connections made over the Internet. Because the traffic is encrypted between the device and the network, traffic remains private as it travels. An employee can able to work outside the office as well as still securely connect to the corporate network. Even smartphones and tablets can connect through a VPN (Virtual Private Network).
What is secure remote access?
Secure remote access provides a safe, secure way and to connect users as well as devices remotely to a corporate network. It includes Virtual Private Network technology that uses strong ways to authenticate the user or device. Virtual Private Network technology is available to check whether a device meets certain requirements, also called a device’s posture, before it is allowed to connect remotely.
Is VPN traffic encrypted?
Yes, The traffic on the virtual private network is sent securely by establishing an encrypted connection across the Internet popularly known as a tunnel. Virtual Private Network traffic from a device such as a computer, tablet, or smartphone is encrypted as it travels through this tunnel. Employees (Offsit) can use the virtual network to access the corporate network.
Virtual Private Network Security
Security is one of the main reason for why corporations have used Virtual Private Network for many years. Many simple methds are increasing to intercept data travelling to a network. WiFi spoofing and Firesheep are the two easy ways in order to hack information.
A useful analogy is that a firewall protects your data while on the computer and a Virtual Private Network protects your data on the web. Virtual Private Networks use advanced encryption protocols and secure tunneling techniques to encapsulate all online data transfers.
Most of computer users didn’t dream of connecting to the Internet without a firewall and up-to-date antivirus.
“What is VPN And How does a virtual private network (VPN) work?“
Evolving security threats and increasing reliance on the Internet has made a Virtual Private Network as an essential part of well-rounded security. Integrity checks ensure that no data is lost and the connection has not hijacked. Since, all traffic is protected and many Virtual Private Network are preferred over proxies.
Setting Up a VPN
Setting up a Virtual Private Network is a straightforward process. It’s often as simple as entering a username and sever address. The dominant smartphones can configure Virtual Private Networks (VPN) using PPTP and L2TP/IPsec protocols. All those major operating systems can configure the PPTP-VPN connections. Open Virtual Private Network and L2TP/IPsec protocols require a small open source application (OpenVPN) and certificate download.
Virtual Private Network Protocols
The protocols along with available security features can continue to grow with time. The most common protocols are:
PPTP – PPTP has been around the days of Windows 95. The main selling point of PPTP is that it can simply setup on every major OS. In short, PPTP tunnels a point-to-point connection on the GRE protocol. Unfortunately, the security of the PPTP protocol has called into the question in recent years. It is still strong, but it not the most secure.
L2TP/IPsec – L2TP over IPsec is more secure than PPTP and offers many features. It is a way of implementing two protocols together in order to gain the best features of each of them. For example, the L2TP protocol is oftenly used to create a tunnel and IPsec provides a secure channel. These measures make for an impressively secure package.
Open VPN – OpenVPN is an SSL-based VPN that continues to gain the popularity. The software is being used in open source and freely available. SSL is a mature encryption protocol, and OpenVPN can run on a single UDP or TCP port, making it extremely flexible.
Using a Corporate VPN in Windows
Connecting to a VPN is fairly simple. In Windows, press the Windows key, type VPN, and then click the Set up of virtual private network connection option. (If you use Windows 8, you have to click on the Settings category after searching.)
Use wizard for entering the address and login credentials of the VPN service which you want to use. You can then connect to and disconnect from VPNs using the network icon in the system tray – the same one where you manage the Wi-Fi networks you’re connected to.
Other Example Uses for VPNs
VPNs is a fairly simple tool, but they can used to do a wide variety of things:
- Evaluate Business Network While Travelling: VPN (Virtual Private Network) are generally used by business travellers to access their business’ network, including all of its local network resources, while on the road. The local resources didn’t have to exposed directly to the Internet that increases security.
- Access Your Home Network While Travelling: You can also set up your own VPN in order to access your own network while travelling. This will allow you to access a Windows Remote Desktop over the Internet, by using local file shares, and play games over the Internet only if you were on the same LAN i.e (local area network).
- Protect Your Browsing Activity From Your Local Network and ISP: If you are using a public Wi-Fi connection, browsing activity on non-HTTPS websites is visible to all nearby, if they know how to look. If you want to hide your own browsing activity for a bit more privacy, then you can connect to an VPN. The local network is a single and secure VPN connection. All the other traffic will travel on VPN connection. This can be used to bypass connection-monitoring with your Internet service provider, must remember that VPN providers may opt to log the traffic on their ends.
- Evaluate Geo-Stop up Websites: Whether you’re an American trying to access your Netflix account while travelling out of country or you wish to use Australian media sites like Netflix, Pandora, etc you’ll be able to access these region-restricted services if you connect to a VPN located in the Australia.
Downloading Files: Yes, let us be honest – many people generally use VPN connections to download files via BitTorrent. This can be useful even if you’re completely downloading legal torrents – if your ISP is throttling BitTorrent and making it extremely slow, So you can use BitTorrent on a VPN to get fast speeds. Those similar is true for other types of traffic, your ISP might interfere with VPN traffic itself.
