Network Security

This chapter guides you on how to protect your home network from cyber attacks and

unauthorized access by implementing these three network security functions. You

can protect your home network against DoS (Denial of Service) attacks from flooding

your network with server requests using DoS Protection, block or allow specific client

devices to access your network using Access Control, or you can prevent ARP spoofing

and ARP attacks using IP & MAC Binding.

This chapter contains the following sections:

Protect the Network from Cyber Attacks

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 ICMP (Internet Control

Message Protocol) flood attack.

•

UDP-FlOOD Attack Filtering

- Enable to prevent the UDP (User Datagram

Protocol) flood attack.

•

TCP-SYN-FLOOD Attack Filtering

- Enable to prevent the TCP-SYN (Transmission

Control Protocol-Synchronize) flood attack.

Tips:

The level of protection is based on the number of traffic packets. The protection will be triggered immediately

when the number of packets exceeds the preset threshold value (the value can be set on

Access Control

Access Control is used to block or allow specific client devices to access your network

(via wired or wireless) based on a list of blocked devices (Blacklist) or a list of allowed

devices (Whitelist).
