Describe an example of a voluntary DoS attack.
What will be an ideal response?
A voluntary DoS occurs when the sysadmin has allowed (and sometimes laboriously designed) the system to perform a variety of services without considering the system's limitations. One example of a voluntary DoS attack is an administrator designing the VoIP system with 120 phones, projecting an average phone use of 20%, which is to say that only one out of five users will be on the phone at any given time. This works marvelously until the end-of-month company-wide marketing conference call from the company president. If 30% of the company's employees are in marketing, and they all attempt to call the conference bridge at the same time, the system will fail. Calls will be dropped and the repair tickets will flow in.
