\subsubsection{Terminology}

\begin{frame}[fragile]
\frametitle{Safety / Security}
Separate Issues

\begin{frame}[fragile]
\frametitle{Safety vs. Security?}
After Delivery
\begin{itemize}
\item Safety: No Changes allowed
\item Security: Continuous Service required (pro-active)
\end{itemize}
\end{frame}

% ----------------------------
\subsubsection{Conclusion}

\begin{frame}[fragile]
\frametitle{Conclusion}
\begin{itemize}
\item KIS - Keep it (the System) simple
