Network Security Components

Adding network security components to your configuration can help protect your device from external intrusion. Network security components, such as Internet Protocol Security (IPSec) and Secure Socket Layer/Transport Layer Security (SSL/TLS), can enhance security when accessing a device over the network.

In addition to adding network security components to your configuration, other precautions should be made to protect your device. Disabling unused ports, and disabling or removing unused services, such as Simple Network Management Protocol (SNMP), reduces the risk of intrusion.

The following tables show network security features and the Windows XP Embedded components that must added to support them.
