Company’s Intrusion Prevention Systems Mitigate Threats to Apache Server, The World’s Most
Widely Used Web Server.
Hudson, MA, Thursday - September 08, 2011 -- Corero Network Security (CNS:LN), a leading
global provider of Network Intrusion Prevention Systems (IPS) and Distributed Denial of Service
(DDoS) Defense Systems, notified customers that it protects them from the ‘Apache Killer’ denial
of service (DoS) exploit with its IPS 5500 products. ‘Apache Killer’ exploits a vulnerability found in
the Apache Web Server software. Although hundreds of DoS vulnerabilities have been
discovered in commercial and open-source software so far in 2011, this particular vulnerability is
significant since Apache Server is the world’s most popular web server, with nearly 66 percent of
the market or nearly 200 million web sites in use, according to Netcraft
( http://www.news.netcraft.com/about-netcraft ).
Corero’s IPS 5500 provides proactive protection for the Apache Killer exploit as a result of its two-
tiered "PVM+DVM" Stateful Protocol Analysis (SPA) implementation. In this case, the IPS 5500
HTTP Protocol Validation Module (PVM) detects and blocks attempts to cause the denial of
service condition on the Apache servers. No new signatures were required for this protection
which was built in to Corero’s IPS solutions.
"Our IPS solution is unique in that it is purpose built to protect not only against traditional flood-
based DDoS and new application layer attacks but also attacks like the Apache Killer. We
safeguard our customers’web servers from Apache Killer denial of service exploits that can be
caused by just a very small number of network transactions," said Mike Paquette, chief strategy
officer, Corero Network Security.
