218 Flash Media Server Security

Edit the security tags in the configuration files Utilize the limits that can be set in the

server’s configuration files. Use the following tags in the configuration files to enhance the

server’s security:

■ Server.xml file

The HostPort tag nested in AdminServer container allows you to specify the port of your

choice for connecting to the Admin service with the management console. This allows

you to use a port that will work with your firewall configuration. The default is port 1111.

The ServerDomain tag lets you specify the domain that the Flash Media Server is running

in so that it can identify its domain to application servers you may want it to connect

to.

The SSL tags let you specify your digital certificates used for client connections. If you

want secure connections using the RTMPS protocol, you must enter appropriate values in

the

SSL tags.

■ Users.xml file

The User tags allow you to specify exactly who can connect to the server with the

management console. Only users specified with these tags can connect.

The Allow and Deny tags let you specify exactly which domains administrators can

connect from. Administrators cannot connect from domains that are not permitted with

these tags. If you are running the server on a Linux system, remember to allow

connections from the domains where administrators will use the console to manage and

monitor the server and its running applications.

■ Adaptor.xml file

The Allow and Deny tags let you specify exactly which domains administrators can

connect from. Administrators cannot connect from domains that are not permitted with

these tags. These tags indicate permissions specifically for the adaptor. If you are running

the server on a Linux system, remember to allow connections from the domains where

administrators will use the console to manage and monitor the server and its running

applications.

The HostPort tag allows you to specify the port to use for client connections and specify

if a port is secure or not. This lets you choose a port that works with your firewall

configuration. The default for RTMP connections is port 1935. The

secure attribute of

the

HostPort tag, set to a value of true, allows you to specify that the port uses secure

FRTMP (RTMPS) for client connections. The default secure port is 443.

■ Vhost.xml file

The MaxConnectionThreads tag nested in the ResourceLimits container allows you

to limit the number of threads to use for processing input/output requests. This prevents

denial-of-service attacks from bringing down the server computer itself.
