How proactive endpoint security works
In traditional SSL, sensitive data exists in plain text until the point of encryption, leaving it vulnerable to interception or tampering. Proactive endpoint security avoids this problem by ensuring that sensitive information is never present in the data stream until the point of encryption.
A credit card holder will enter his or her username and password into the appropriate fields to access personal banking information or a credit card number to make an online purchase. When the information is transmitted for verification, rather than inserting the unencrypted sensitive information, endpoint security technology inserts variables into the data stream at locations where the remote server is expecting the sensitive information.
Next, the technology securely redirects the data stream to a secure location where the sensitive information is stored, such as a smart card, USB device, mobile phone, etc., or a software location (i.e., network server or protected storage area).
Inside this secure location, the variables are replaced with actual sensitive data (credit card number, usernames, and passwords, etc.), and the data stream is encrypted.
Finally, the encrypted data stream, containing the sensitive information in the format expected by the server, is then passed to the remote server via the SSL protocol. It arrives in the standard SSL format and can be decrypted with the same SSL keys used to protect the Web session.
By leveraging proactive endpoint security, consumers’ sensitive information is never present in the data stream until the point of encryption. Any attempts to intercept the data stream and harvest the data would be useless.
Rather than obtaining the sensitive information, a malicious user would only see meaningless variables, making this the most modern and secure method to shop and bank online.
