Firewall with SPI (Stateful Packet Inspection) support
Its on-board Unauthorized Access Detection function
achieves robust network security (supports log output) The
product utilizes SPI (stateful packet inspection) as its firewall
method. SPI verifies the consistency of packets for each
communication session. Since it blocks all ports upon the
completion of a session, the technology implements a truly
"hole-less" firewall.
Furthermore, SPI blocks communication as soon as it
detects DoS (Denial of Service) attack from the Internet
(WAN side). Detected attacks can be saved in a log, and the
log data can be sent out in the form of syslog or E-mail.
Detectable DoS Attacks
IP Spoofing/ Land Attack/ Ping of Death/ Zero Length IP/
Smurf Attack/ UDP Port Loopback/ Snork Attack/ TCP null
scan/ TCP Synflood
z
Controls access from the LAN side
The product is capable of controlling access to the Internet
from the LAN side. The following access rules (or filters) can
be assigned to each group of PC's attached to the LAN.
(1) Access control by schedule (time/day of the week)
(2) Access control by service (40 services including E-mail
and Web browsing are registered by default. New services
can be added to the list of services to be blocked.
(3) URL filtering (blocks access from PC's on the LAN to
preconfigured URL's. Either the URL, IP address or keyword
for the target URL may be entered. )
z
Supports VLAN
The product supports VLAN (Virtual LAN) feature that
logically segments a LAN port to multiple groups. VLAN
enables communication among ports that belong to the same
VLAN group while it blocks communication between ports
belonging to separate VLAN groups. This feature protects
clients from i)secondary infection of computer viruses and
worms from the source of infection as well as ii)attacks that
use virtual computer terminals and global IP terminals for
