Computer scientists work on network defense UCLA computer
scientists are working on a new tool to prevent network operators
from a harmful internet-based threat ““ distributed denial of
service attacks. DDoS attacks overload a network by bombarding it
with tens of thousands of data streams and prevent access by
legitimate users. A hacker can initiate an attack within five
seconds, compromising thousands of machines on a particular
network. The coordinated attack comes from a lot of computers and
is directed toward one target, crippling its service. DDoS attacks
are capable of interrupting service on high-traffic Web sites like
Yahoo, eBay and CNN, as well as university campus networks
nationwide. Adjunct associate professor of computer science, Peter
Reiher, and computer science doctorate student, Jelena Mirkovic,
both from UCLA’s Henry Samueli School of Engineering and
Applied Science, are working on a program that could protect
networks from these attacks. The automated defense program, DDoS
netWork Attack Recognition and Defense, monitors traffic on
networks to identify potential threats. D-WARD will stop the attack
at the source by focusing on the router which serves as a gateway
between UCLA and the rest of the Internet. All traffic which passes
through the router will also pass through D-WARD for screening.
D-WARD will cut the flow of traffic at the source in the event of
an attack and prevent further harm.

Red Cross to give free flu shots to senior citizens The American
Red Cross of Greater Los Angeles will be administering free flu
vaccinations at 60 selected Southern California sites from Oct. 21
to Nov. 26. Only senior citizens age 60 or older or individuals
with weakened immune systems (chronic illnesses such as heart,
kidney or respiratory disease) will qualify for the free vaccines.
No one under 18 may receive a vaccination at these clinics. The Red
Cross will give vaccinations for this season’s three most
expected strains of flu virus, as predicted by the Centers for
Disease Control. The typical flu season begins January and lasts
through March. A vaccination will provide protection through six
months. This is the 28th year the Red Cross has partnered with the
Los Angeles County Department of Health Services to provide this
service. Vaccines are provided by the Los Angeles County Health
Department. For more information, call 1-800-427-8700. Briefs
