Users who travel know how useful the iPad 2 can be. Since it first launched, many travelers have taken their iPads on trips due to their ease-of-use, accessibility and connectivity. In fact, many travelers prefer their iPads when they travel over a laptop computer. This is because iPads have similar functionality and features, but are more compact.
The only issue with taking along a mobile device while traveling is security. Firewalls and anti-virus software are important. However, they do not do not protect a user’s personal information as it is transmitted on the Internet through an unsecure connection. The iPad 2 is most frequently used on wireless connections. While travelling, users will need to connect through public Wi-Fi networks. When they do so, they are at risk for personal data breeches.
Security through a VPN
With a virtual private network, or VPN, users can establish a secure connection over public hotspots. When a user logs into a VPN, their personal data is transmitted through a secure tunnel. Information that is sent to and from the user’s iPad is encrypted before it is transmitted. The VPN will also help users who are travelling abroad access websites that might otherwise be restricted due to their location.
Choosing a VPN Protocol
iPad users can choose PPTP or L2TP/IPsec as their VPN protocol. PPTP (Point-to-Point Tunneling Protocol) offers fast speeds and 128-bit data encryption. L2TP/IPsec (Layer 2 Tunneling Protocol with IP security) is more secure at 256-bit data encryption, but it is slightly slower. 128-bit data encryption is sufficient for many users, but sensitive or classified information should be protected with 256-bit encryption.
Configuring VPNs for iPad 2
Users should configure and test their VPN service prior to travelling. Setting up a VPN with an iPad 2 is easy. By following these initial setup steps, users can have their VPN service running in just a matter of minutes.
Prior to starting, users should close any applications that access the Internet. They should have on hand the information sent to them in their configuration email from their selected VPN service. Necessary information includes the VPN’s server address, the assigned username and password. If the user has opted for the L2TP/IPsec protocol, they will also need the “shared secret” security key.
- Go to the “Settings” page.
- Select “General.”
- Select “Network.”
- Select “VPN.”
- Select “Add a VPN Configuration.”
- Select the protocol choice, “PPTP” or “L2TP/IPsec.”
- For Description, the user may enter any name they like for their VPN connection.
- In the field marked Server, enter the server address.
- Enter the username and password as assigned by the VPN service.
- If the user has selected the L2TP/IPsec protocol, they will here also be required to enter the shared-secret security key.
- Click on “Save.”
When the user is ready to connect to the Internet using their iPad 2, they will need to go to “Settings” and slide the “VPN” connection to the “On” position. They will then be ready to securely browse the Internet.
