SonicWALL Internet Security Appliance Features

Internet Security

•ICSA-Certified Firewall
After undergoing a rigorous suite of tes ts to expose security vulnerabilities, SonicWALL Interne t
security appliances have received Firewall Certification from ICSA, the i nternationally-accepted
authority on network security. The SonicWALL uses stateful packet inspection, the most
effective method of packet filtering, to protect your LAN from hackers and vandals on the
Internet.
•Hacker Attack Prevention
The SonicWALL automatically detects and thwarts Denial of S ervice (DoS) attacks such as Ping
of Death, SYN Floo d, LAND Attack, and IP Spo ofing.
•Network Address Translati on (NAT)
Network Address Translation (NAT) translates the IP addresses used on your private LAN to a
single, public IP address that is used on the Internet. NAT allow s multiple computers to access
the Internet, ev en if only one IP addres s has been provided b y your ISP.
•Network Access Rules
The default Network Access Rules allow traffic from the LAN to the Internet and block traffic
from the Internet to the LAN. You can create additional Network Access Rules that allow
inbound traffic to ne twork ser vers, such a s Web an d e- mail s erve rs, or t hat r estr ict o utbou nd
traffic to certain destinations on the Internet.
•Autoupdate
The SonicWALL maintains the highest level of security by autom a tically notifying you when new
firmware is released. When new firmware is available, the SonicWALL Web Management
Interface displays a link to download and install the latest firmware.
•DMZ Port
The SonicWALL PRO 100, PRO 200, PRO 300 , PRO 230, and the SonicWALL PRO 330 include
a DMZ port allowing users to access pu blic servers, such as Web and FTP servers. While Internet
users have unlimited access to the DMZ, the servers on the DMZ are stil l pro tected ag ainst D oS
attacks.
•HomePort
The TELE3 TZ and TELE3 TZX include a HomeP ort that allows you to separate company
computers from home computers on your home network yet share the same Internet
connection.
•WorkPort
The TELE3 TZ and TELE3 TZX include a WorkPort that allows you to isolate your IPSec VPN and
secures your corporate connec t i ons with a stateful packet inspection firewall.
•SNMP (Simple Net w or k Ma n agement Protocol) Support
SNMP is a network protocol used over User Datagram Protocol (UDP) that allows network
administrators to monitor the status of the SonicWALL Internet Security Appliances and receive
notification of any critical events as they occur on the network.
