VBrick Systems VB4000, VB6000, VB5000 manual Improving Security

	WM Configuration
External IWS	Default = Enabled. Disabled will prevent you from managing the
	VBrick from a web browser using the IWS application.
External SNMP	Default = Enabled. Disabled will prevent you from using an external
	MIB browser to view or write parameters.
External SNMPv1	Default = Enabled. You can use both SNMP v1/v2, and v3. For
and SNMPv2 Access	tightest security, set parameter to Disabled and use SNMPv3 only.
No Login For Viewer	Default = Enabled. Various files available for use by players and
Files	decoders including SDP, ASX, and NSC files. When enabled, access
	to these files does not require login with username and password.
Allow Load Simulator	Default = Disabled. Allows a Microsoft Load Simulator to connect
	to the VBrick WM Appliance (server) for testing. The Windows
	Media Load Simulator 9 Series is a GUI-based tool that simulates a
	large number of client requests on a Windows Media server. If you
	are testing a WM appliance with this simulator, be aware that VBrick
	v4.0 or later WM Appliances are only compatible with Release
	9.0.0.2939 or higher of the Windows Media Load Simulator. For
	more information go to http://www.microsoft.com/technet/
	prodtechnol/netshow/downloads/loadsim.mspx
RTSP Server Port	Default = 554. Sets the RTSP server port.
IWS Server Port	Specifies the listener port for management and HTTP connections.
	Default = 80. When the remote IWS user (client) specifies the http
	syntax, the port value is generally omitted. Typically port 80 is the
	default value used by browsers. As a matter of consistency, the
	VBrick default IWS Server Port value is also defaulted to 80. To
	access a different HTTP port, the remote IWS client user would
	specify the URL as follows: http://IPaddress:port where IPaddress =
	VBrick IP address or hostname, and port. This feature is often useful
	for an system where HTTP is used to traverse firewalls. The IWS
	server port is moved to another location (for example 8080) and the
	HTTP Tunneling port (or the Windows Media HTTP port) is set to
	80.
Windows Media	Sets the port to be used to serve Windows Media HTTP streams.
HTTP Port	Default is 8080 but if you are streaming HTTP directly from a
	VBrick via the Internet, it is common practice to change this to 80
	and to set the IWS server port to something other than 80.
Push Receive Port	Default = 7070. Sets the port used by the Reflector push receiver.

Improving Security

You can improve security by (1) blocking unauthorized attempts to login and access a device and (2) by reducing exposure to malicious software attacks. The most common vulnerability is related to user accounts and passwords. After a successful installation, you should immediately change the default passwords. Many attacks come from within an organization and this helps to minimize the risk. The IWS login is generally secure since it utilizes encryption techniques to hide usernames and passwords from network spyware.

Malicious software covertly attaches itself to unsuspecting devices. These programs are generally designed to compromise personal information or to create system havoc. Since the VBrick appliance uses an industrial-grade operating system, it is less susceptible to malicious
