“In its clearest signal yet that it may be bracing for a
massive attack, computer network security group CERT issued an
advisory today asking system administrators to prepare systems to
block denial of service attacks.”
“The advisory, titled DenialofService Vulnerabilities in TCP/IP
Stacks, warns admins to harden and closely monitor systems in
anticipation of an attack.”
“Denialofservice attacks are possible whenever an attacker can
consume a limited resource on a victim’s machine. Examples of the
kinds of resources that an attacker can consume are CPU time,
network bandwidth, and volatile and nonvolatile memory,” the
advisory says.”
