Firewall Screens

You can configure firewall filters and alert notifications for your home network. The SBG6782-AC

firewall protects the SBG6782-AC LAN from unwanted attacks and other intrusions on the

Internet. Firewall protection also provides the following benefits:

•

Advanced, integrated stateful-inspection firewall supporting intrusion detection, session

tracking, and denial-of-service attack prevention.

•

Maintains state data for every TCP/IP session on the OSI network and transport layers.

•

Monitors all incoming and outgoing packets, applies the firewall policy to each one, and

screens for improper packets and intrusion attempts.

•

Generates comprehensive notifications for the following:

ο

User authentications

ο

Rejected internal and external connection requests

ο

Session creation and termination

ο

Outside attacks (intrusion detection)

Protection Level

The Firewall Protection Level screen has various settings related to blocking or exclusively

allowing different types of data through the SBG6782-AC from the WAN to the LAN. There are

three security firewall protection levels which correspond to how many services are allowed:

•

High

- Safest configuration, highest security

•

Medium

- Common configuration, modest risk

•

Low

- Minimum security, higher risk

•

Off

- No security, highest risk

Firewall protection enables the Stateful Packet Inspection (SPI) firewall features. Block

Fragmented IP packets prevent all fragmented IP packets from passing through the firewall. Port

Scan Detection detects and blocks port scan activity originating on both the LAN and WAN. IP

Flood Detection detects and blocks packet floods originating on both the LAN and WAN.

You can block Java Applets, Cookies, ActiveX controls, pop up windows, and Proxies.
