Tutorial: A denial-of-service attack can prevent the normal
conduct of business on the Internet. There are four types of
solutions to this security problem:
- Awareness: Maintaining cognizance of security threats and
vulnerabilities. (See: CERT.)
- Detection: Finding attacks on end systems and subnetworks.
(See: intrusion detection.)
- Prevention: Following defensive practices on network-connected
systems. (See: [R2827].)
- Response: Reacting effectively when attacks occur. (See: CSIRT,
contingency plan.)
