\begin{itemize}
\item Can precise synchronisation play a role in security?
\begin{itemize}
\item Monitoring network latency?
\item Monitoring program execution times?
\item Complementing other sources of time (e.g. GPS) for
redundancy in applications calling for robust time distribution?
\end{itemize}

\item What about security in IEEE-1588 itself? Four-prong
approach in new revision of the standard:
\begin{itemize}
\item Integrated security mechanisms (authentication and
integrity of messages through encryption).
\item External transport security mechanisms (MACSec, IPSec).
\item Architectural mechanisms (e.g. redundancy).
\item Monitoring and management.
