Chapter 25 Secure Socket Layer 189
CHAPTER 25
Secure Socket Layer
This chapter shows you how to setup and enable Secure Socket Layer (SSL) security on the
VSG.
25.1 About SSL
SSL (Secure Socket Layer) security is a standard Internet protocol for secure communications
that uses a combination of certificate-based authentication and public-key encryption. SSL
protects data transfer between the web configurator on the VSG and the web browser on a
connected computer.
With SSL security activated, data (such as user name and password) transferred between the
VSG and the computer is protected when you access the VSG using a web browser that
supports SSL.
25.1.1 Certificate
A digital certificate (also referred to as a certificate) contains the key owner’s name and public
key, the name of the issuing certification authority, the certification authority’s digital
signature and a certificate validity time limit and other optional information fields.
25.1.2 Certificate Authorities
A Certification Authority (CA) issues digital certificates and guarantees the identity of the
certificate owner. When someone requests a certificate from a CA, the CA requires proof of
identity. There are both commercial certificate authorities like CyberTrust and VeriSign, as
well as government certificate authorities.
25.2 Downloading SSL Certificate to the VSG
After you apply for and receive a certificate from a certificate authority, import the certificate
and the private key to the VSG.
Click System Tools and SSL Certificate in the navigation panel to display the screen as
