Primes

• Principle of Least Privilege
  • The minimization rule and temporal scoping together fix this: the daemon binds the port as root (the one moment root is necessary), then immediately calls setuid to an unprivileged account and chroots into the public directory, dropping every grant its post-startup function does not require.

    This sourceDocuments binding a privileged port as root then dropping privileges via setuid and chroot to confine a daemon's post-startup authority.
