When you find yourself using a public wi-fi network, there are 2 methods to guaranteeing that computer data coming and going from the pc is encrypted.
One procedure requires securing every individual application. With regard to web site browsing, this means only making use of secure HTTPS web pages. For the purpose of reading electronic mail, it means using secure protocols such as POPS or APOP as opposed to regular POP.
On a technical level, some apps cannot be run safely and securely. It could be, as an example, that your favorite Instant Messaging program often delivers everything in plain text. On a human level, this can be a pain to configure applications to run securely and then to always be sure of what software applications are secure and protected and which are’nt.
A much better approach is a Virtual Private Network (VPN) that creates a secure and safe, encrypted connection used all data moving in and out of your computer. Whether the data is a web site page, a e mail message, a IM or even a FTP file transfer, the VPN encrypts it without making changes to the applications themselves.
Corporate VPNs create an encrypted path (tunnel being the actual recognized term) between a traveling employee together with their home office. Consumer VPNs create a encrypted path between your computer or even smart phone and servers operated through the VPN company.
Having a corporate and business VPN, information is encrypted till the point it hits your home office. With a consumer VPN, data is encrypted until it hits the servers of the VPN company after which it’s always decrypted and delivered to cyberspace to its eventual destination. The purpose of a consumer VPN is to encrypt everything traveling over the air. The objective of a corporate VPN would be to encrypt data end-to-end
