DX8100 SECURITY
INTERNET PROTOCOL SECURITY
The DX8100 features built-in network security using Internet Protocol Security (IPSec). IPSec facilitates authentication and encryption at the
network packet level. IPSec services protect the DX8100 from unwanted or potentially damaging network requests. With IPSec enabled, the
DX8100 DVR will not respond to any unsecured communication across the network, whether friendly or malicious. IPSec only blocks unwanted or
unauthorized communication flowing to the DX8100. It does not hinder communication sessions that are initiated by the DVR.
IPSec is enabled by default on the DX8100; however a system administrator can disable the service if it is deemed necessary for the proper
functioning of the unit.
To disable IPSec services on the DX8100 Series DVR:
1. Exit the DX8100 application if it is running, and return to the Windows operating system.
2. Go to Start > Programs > Manage IPSec Policy. The DX8100 IPSec Policy dialog box opens.

3. Deselect the Enable DX8100 IPSec Policy check box. Reselect the Enable DX8100 IPSec Policy check box to re-enable IPSec.
4. Click OK.
FIREWALLS
The DX8100 includes the Windows firewall that comes with Service Pack 2 for Windows XP. The security services provided by the Windows
Firewall protects the DX8100 from unwanted or potentially damaging network requests. With the Windows Firewall and IPSec enabled, the
DX8100 DVR will not respond to any unsecured communication across the network. However, there are potential risks to which you should be
aware. The Windows Firewall does not block all ports. For a list of ports required for operation, refer to DX8100 Network Ports on page 19.
Pelco recommends that an external network firewall be used. The network firewall will provide additional protection for the DX8100. Regardless
of which port or service is under attack, the port must be open or at least visible in order for the malicious program to exploit it. Firewalls filter
and render all unneeded ports invisible, providing excellent protection against such attacks. Networked systems exposed in anyway to the
outside world (for example, when connected to the Internet) should be equipped with network-based firewall protection.
WARNING: Disabling IPSec services will expose your DX8100 Series DVR to potentially damaging network traffic. It is highly
recommended that IPSec is enabled at all times for the protection of your system.
