SonicWALL Internet Security Appliance Features
Internet Security
• ICSA-Certified Firewall
After undergoing a rigorous suite of tests to expose security vulnerabilities, SonicWALL Internet
security appliances have received Firewall Certification from ICSA, the internationally-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 Service (DoS) attacks such as Ping
of Death, SYN Flood, LAND Attack, and IP Spoofing.
• Network Address Translation (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 allows multiple computers to access
the Internet, even if only one IP address has been provided by 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 network servers, such as Web and e-mail servers, or that restrict outbound
traffic to certain destinations on the Internet.
• Autoupdate
The SonicWALL maintains the highest level of security by automatically 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 public servers, such as Web and FTP servers. While Internet
users have unlimited access to the DMZ, the servers on the DMZ are still protected against DoS
attacks.
• HomePort
The TELE3 TZ and TELE3 TZX include a HomePort 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 connections with a stateful packet inspection firewall.
• SNMP (Simple Network Management 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.
