28.3 Introduction to ZyXEL’s Firewall
The ZyAIR firewall is designed to protect against Denial of Service attacks. The ZyAIR’s purpose is to allow
a private Local Area Network (LAN) to be securely connected to the Internet. The ZyAIR can be used to
prevent theft, destruction and modification of data, as well as log events, which may be important to the
security of your network. The ZyAIR also has packet-filtering capabilities.
28.4 Denial of Service
Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet. Their
goal is not to steal information, but to disable a device or network so users no longer have access to network
resources. The ZyAIR is pre-configured to automatically detect and thwart all known DoS attacks.
