38. Writing Secure Privileged Programs > Beware of Denial-of-Service Attacks

Beware of Denial-of-Service Attacks

With the increase in Internet-based services has come a corresponding increase in the opportunities for remote denial-of-service attacks. These attacks attempt to make a service unavailable to legitimate clients, either by sending the server malformed data that causes it to crash or by overloading it with bogus requests.

Note

Local denial-of-service attacks are also possible. The most well-known example is when a user runs a simple fork bomb (a program that repeatedly forks, thus consuming all of the process slots on the system). However, the origin of local denial-of-service attacks is much easier to determine, and they can generally be prevented by suitable physical and password security measures.
