How Does Secure Socket Layer (SSL or TLS) Work?

Monday, July 22nd, 2013

The Secure Socket Layer, SSL for short, is a protocol by which enables services that communicate over the Internet to do so securely.

SSL has recently been replaced by TLS (Transport Layer Security).  TLS is newer and more secure than SSL (See TLS vs SSL: What is the difference?); however, from a lay-person’s perspective of “how does it work,” they are functionally the same.  We use the term “SSL” to refer to both TLS and SSL in this article for simplicity.

Before we discuss how SSL works and what kinds of security it provides, let us first see what happens without SSL.

Life on the Internet without SSL

This is, for example, what happens when you go to any web page whose address begins with “http://” (and not “https://”).

Let us compare communications on the Internet and communications between people over the telephone. Without SSL, your computer-to-computer communications suffer from the same security problems from which your telephone communications suffer:

Ensuring all data is encrypted at rest with LuxSci

Friday, May 10th, 2013

Email and other data is either being “transmitted” or “processed” or is “at rest.”  I.e., it is moving from one computer to another, or it is stored/at rest on a computer, or it is preparing to be transmitted or stored.

While most types of compliance regulation, such as HIPAA, specifically require that data be transmitted securely, not all regulations require that data be stored in an encrypted form while at rest.  I.e., HIPAA does not require at-rest encryption, though it is recommended to decrease risk and potential liability in some situations

Having your email and other data encrypted while at rest can potentially increase the security of that data, even if that level of security is not explicitly required.  As a result, many LuxSci customers have asked about how to ensure that all of their email and other data is encrypted while at rest.
