As a business owner, it is your responsibility to make sure your electronic information is kept safe and secure. There are different things which you can do to prevent unwanted intrusions and access to this information. For example, when sending data over the internet, you will want to make sure you are using public key cryptography to encrypt your data.
Public Key Cryptography Can Be Used with Other Methods to Increase Security
Public key cryptography is only one kind of encryption and security you can use to protect your data. You can combine this method with others, such as two factor authentication. In this scenario, you would require users to use a digital certificate, when connecting over a public network, first, before they would be able to enter in their user name and password. After successful authentication, then they would be allowed to send or receive data.
