Firewall Settings: Denial of Service
A Denial of Service attack is an attempt by a user (or users) to
make a server’s or network’s services unavailable. The user
sends a server multiple requests with false return addresses.
The server will attempt to respond by sending a request back to
the user; however, since the address is false, the server will wait
for a response before closing the connection. When multiple
requests like this occur, servers may often get overloaded with
too many requests and stop functioning all together. This is a
typical DoS attack, although DoS attacks may not be limited to
this type of attack.
The High Power Router can assist in preventing these types of
attacks by scanning the network for patterns of activity that
represent DoS attacks. If a pattern comes in frequently, the
High Power Router can attempt to block messages containing
that pattern and thus protect the server from becoming
overloaded and unresponsive.
