11.1.2 What You Need to Know About The Maintenance Screens

HTTPS
HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL is a web protocol
that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level
protocol that enables secure transactions of data by ensuring confidentiality (an unauthorized
party cannot read the transferred data), authentication (one party can identify the other party)
and data integrity (you know if data has been changed).
Public Key Certificate
Public key certificates are used by web browsers to ensure that a secure web site is legitimate.
When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few,
receives a certificate request from a website operator, they confirm that the web domain and
contact information in the request match those on public record with a domain name registrar.
If they match, then the certificate is issued to the website operator, who then places it on his
site to be issued to all visiting web browsers to let them know that the site is legitimate.
Syslog Server
The syslog protocol is built around data logging for the purposes of keeping records and
analysis. On a typical network the syslog daemon can be configured to send system logs to a
central online repository known as a syslog server. This allows the network administrators to
quickly access and examine them without having to go to every machine on the network.
