2. What is SSL?
Secure Sockets Layer (SSL) is the most widely deployed cryptographic
protocol to provide security over internet communications.
SSL provides a secure channel between two machines or devices operating
over the internet or an internal network. One common example is when
SSL is used to secure communication between a web browser and a web
server. This turns a website's address from HTTP to HTTPS, the ‘S’ standing
for ‘secure’.
3. Why is it a must?
In order to accept credit card information on your website, you must
pass certain audits that show that you are compliant with the
Payment Card Industry (PCI) standards. One of the requirements is
properly using an SSL Certificate.
It provides privacy, critical security and data integrity for your
website and your users' personal information.
4. SSL Certificate
To be able to create an SSL connection a web server requires an SSL
Certificate.
When you choose to activate SSL on your web server you will be asked to
complete a number of questions about the identity of your website and your
company.
SSL certificate ensures that any data transferred between users and sites
remain impossible to read. It uses encryption algorithms to scramble data in
transit, preventing hackers from reading it as it is sent over the connection.
This information could be anything sensitive or personal which can include
credit card numbers and other financial information, names and addresses.
5. How does a SSL Certificate work?
When a browser attempts to access a website that is secured by SSL, the browser
and the web server establish a SSL connection using a process called a “SSL
Handshake”. Note that the SSL Handshake is invisible to the user and happens
instantaneously.
Three keys are used to set up the SSL connection: the public, the private, and the
session keys. Anything encrypted with the public key can only be decrypted with
the private key, and vice versa.
Because encrypting and decrypting with private and public key takes a lot of
processing power, they are only used during the SSL Handshake to create a
symmetric session key. After the secure connection is made, the session key is
used to encrypt all transmitted data.
Everything happens in the following steps:
6. How does a SSL Certificate work?
A browser connects
to a web server
(website) secured
with SSL (https). A
browser asks the
server to identify
itself.
A server sends a
copy of its SSL
Certificate,
including the
server’s public
key.
A browser checks if
the certificate is
obtained from a
certified authority
and is valid (i.e.
unexpired,
unrevoked, etc.)
If the browser trusts
the certificate, it
creates, encrypts,
and sends back a
symmetric session
key using the
server’s public key.
The server decrypts
the symmetric session
key using its private
key and sends back
an acknowledgement
encrypted with the
session key to start
the encrypted session.
The server and the
browser now
encrypt all
transmitted data
with the session
key.
7. How does it look like?
Web browsers give visual cues, such as a lock icon or a green bar, to
make sure visitors know when their connection is secured.
8. SSL can be used to secure:
Online credit card transactions or other online payments.
Intranet-based traffic, such as internal networks, file sharing, database connections.
Webmail servers like Outlook Web Access, etc.
The connection between an email client such as Microsoft Outlook and an email
server such as Microsoft Exchange.
System logins to applications and control panels like Parallels, cPanel and others.
Workflow and virtualization applications like Citrix Delivery Platforms or cloud-
based computing platforms.
Hosting control panel logins and activity like Parallels, cPanel and others.
