A firewall protects a private network against Internet
based theft, destruction, or modification of data by examining all
traffic passing from the Internet or Wide Area Network (WAN) to
the private, Local Area Network (LAN).
In our company, the term “Firewall” is used for real firewalls
offering multiple techniques. There is a tremendous difference between
“real firewalls” and small, personal appliances or inexpensive port
blocking and NAT’ing (Network Address Translation) hardware or software
sold publicly under the “Firewall” label.
The MISappliance is based on dynamic, stateful firewall techniques.
Dynamic packet filtering examines data transmissions at a low level
and is then able to more intimately interact with the firewall rules
to more precisely secure the network. This technique allows the
MISappliance to easily block port scans, computers specified in
the MISopcenter and other malicious traffic such as IP spoofing.

DoS (Denial of Service) Mitigation
· Strict Firewall Settings
· Continuous Monitoring
· Alerts MIS of Suspicious Activity
· Detects "Smurf" Attacks
Strict firewall settings prevent DoS attacks by dropping malicious
packets and reporting them to the MISopcenter. The MISappliance
is also configured to only reply to ICMP ping requests from local
users behind the machine and our MISopcenter. It is “invisible”
from outside, since it will not respond to pings that are used to
detect a “living machine” at a given address. This mitigates “Smurf”
and other DoS attacks relying on servers that reply to ping requests.
