Prevention
As a fork bomb's mode of operation is entirely encapsulated by creating new processes, one way of preventing a fork bomb from severely affecting the entire system is to limit the maximum number of processes that a single user may own. On Linux, this can be achieved by using the ulimit utility; for example, the command ulimit -Hu 30 would limit the affected user to a maximum of thirty owned processes. On PAM-enabled systems, this limit can also be set in /etc/security/limits.conf, and on FreeBSD, the system administrator can put limits in /etc/login.conf.
