This will ensure that secure data cannot be accessed through standard HTTP connection. The show ip http server command can be used for detailed status information about the HTTP
server.
By default, the HTTP server uses the standard TCP port 80, and Secure HTTP (HTTPS) uses the standard TCP port 443. These
ports can be changed to user-defined ports by using the ip http port {port} command and the ip http secure-port {port}
command, respectively. Only values above 1024 are accepted.
For more granular security, an authentication mechanism can be used for login when a client connects to HTTP server, coupled
with an access list to restrict the access of HTTP service to authorized users only. The ip http access-class {access-listnumber}
command can be used to define sets of IP addresses and networks that are permitted or denied access. The ip http
authentication command can be used to enable authentication using the AAA, enable , local , and tacacs methods.
If HTTP and HTTPS services are not required, they can be disabled by using the no ip http server command and no ip http
secure-server commands, respectively, from the global configuration mode.
Network Time Protocol (NTP)
The heart of the time service is the system clock.
