VPN or Virtual Private Network is special because it extends the resources integrated into its network, to another network in the public sector like the Internet, thereby facilitating a host computer sending and receiving data across public and shared networks. Moreover, this entire process takes place with the functional capabilities of the private network, supported by its security and its management policies. A virtual point-to-point connection establishes this capability by dedicated connections, encryption or a blend of both. This connection is actually a WAN (Wide Area Network) link but appears as a private network link to the user, which is why they call it “Virtual Private Network.”
Mobile phones also use virtual private network to provide access to software applications and network resources on their home turf, especially when networked through either wired or wireless networks.
Most current smartphones, when loaded with cloud-based telephony, will function like a PBX. Under these circumstances, mobile security is a matter of great concern. Even 3G networks, though they can encrypt messages between handsets and the base station of the carrier, cannot deal with network configurations, which only a virtual private network (VPN) can handle. With the mobile devices becoming a major instrument for business, securing the network takes on daunting proportions.
Prevention of internet/work roaming disruptions was the main reason for introducing VPN on devices, especially on mobile phones. Notwithstanding the current location of a mobile phone, the mobile VPN would help to deliver communication to another device through specially encrypted tunnels. You need not worry about the fate of the message without the wireless coverage, as the recipient will receive the message when the connection resumes. When you have a company work force moving between 3G/4G networks and Wi-Fi hotspots, a mobile VPN is the best option. The only catch is that you need a compatible mobile product installed with client software.
A VPN Service will enable you securely to connect to any server in the network. For this purpose, they will provide an anonymized IP address and encrypt your entire communication with several VPN servers that they locate over a wide area geographically. To get the right VPN service you must learn how they work.
Every computer and phone has a particular IP address that also indicates your location. Miscreants use spyware and malware to hack your computer to find your location. You can protect your identity and personal information by using anonymous SSL VPN servers to hide IP. The VPN server will disguise and conceal IP of your mobile phones and encrypt the data transmitted to provide you with additional security. To explain it further, the SSL uses two keys (a public key and a private key known only to the user) to encrypt data in the cryptographic system. Clients connected to a server can securely send unlimited information between themselves and corporate communication through any mobile device with an Internet browser is secured.
You can secure your mobile phone applications by choosing devices that have encryption integrated into it. Although using secure encrypted applications may seem easier than setting up a VPN, you will never get the consistent security that the VPN can offer all the time.
