Network Security
9. 1. Protect the Network from Cyber Attacks
The SPI (Stateful Packet Inspection) Firewall and DoS (Denial of Service) Protection
protect the router from cyber attacks.
The SPI Firewall can prevent cyber attacks and validate the traffic that is passing
through the router based on the protocol. This function is enabled by default, and it’s
recommended to keep the default settings.
DoS Protection can protect your home network against DoS attacks from flooding your
network with server requests. Follow the steps below to configure DoS Protection.
1. Visit http://tplinkwifi.net, and log in with the username and password you set for
the router.
2. Go to Advanced > Security > Settings.
3. Enable DoS Protection.
4. Set the level (Off, Low, Middle or High) of protection for ICMP-FLOOD Attack
Filtering, UDP-FlOOD Attack Filtering and TCP-SYN-FLOOD Attack Filtering.
• ICMP-FLOOD Attack Filtering - Enable to prevent the ICM (PInternet Control
Message Protocol) flood attack.
• UDP-FlOOD Attack Filtering - Enable to prevent the UDP (User Datagram
Protocol) flood attack.
