Ssl/tls
 

What exactly does SSL/TLS pertain to.
Is it the program?, hardware? or what?

How/what do you check or upgrade?
thanks

can anyone tell me?

I was able to find this!

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols which provide secure communications on the Internet for such things as web browsing, e-mail, Internet faxing, and other data transfers. There are slight differences between SSL 3.0 and TLS 1.0, but the protocol remains substantially the same. The term "TLS" as used here applies to both protocols unless clarified by context.

What is SSL/TLS and how secure is it?

SSL/TLS is the same kind of encryption system used by 'https' web pages.
It is generally considered to be the most (if not only) secure method for sending
sensitive information across the internet, and is the basis of all ECommerce security systems used today.

When you use a SSL/TLS enabled FTP server with your SSL/TLS enabled FTP client,
the control and data connections are fully encrypted so no one can spy on the data or your commands or your password,
as is possible with all non encrypted FTP sessions.

It comprises a set of three protocols, TLSv1, SSLv2 and SSLv3.
The oldest is SSLv2 and hardly used nowdays, TLSv1 is very similar to SSLv3 and only considered marginally better.
If these protocols are all enabled in server and client,
when a connection is opened in SSL mode, the underlying SSL chooses the best protocol.
The three protocols are referred to as "SSL/TLS" or simply "ssl", which stands for "Secure Socket Layer"

thank you
