CIAC has issued Bulletin G-48 on the denial-of-service
attacks by TCP SYN flooding and IP spoofing.
Two "underground magazines" for intruders have
recently published code to conduct denial-of-service
attacks by creating TCP "half open" connections. Any
system connected to the Internet and providing
TCP-based network services such as a Web server, FTP
server, or mail server is potentially subject to this
attack. Systems providing TCP-based services to the
Internet community may be unable to provide those
services while under attack and for some time after
the attack ceases. See the bulletin below for
information on how to protect your site from these
attacks.
