# man sshd / UsePrivilegeSeparation
UsePrivilegeSeparation
Specifies whether sshd separates privileges by creating an un-
privileged child process to deal with incoming network traffic.
After successful authentication, another process will be created
that has the privilege of the authenticated user. The goal of
privilege separation is to prevent privilege escalation by con-
taining any corruption within the unprivileged processes. The
default is ``yes''.
