 \subsection{Objectives}
-%1. Objective
-The objective of this document is to propose a testing approach for an
-implementation of the \textit{Transmission Control Protocol}.
-\textit{Transmission Control} Protocol, from now on \textit{TCP}, is a
-communication protocol that provides a reliable connection on using a
-host-to-host protocol.

+The objective of this document is to provide an approach for testing a
+particular implementation of \textit{Transmission Control Protocol} (TCP). TCP
+is a host-to-host protocol that provides a reliable communication. 
 
-%2. Test Goal
+This testing approach can be used by either an internal test team or an
+independent testing team. The test effort's goal is to become confident about
+the conformance of the implementation to the specification created by
+\textit{The Internet Engineering Task Force}
+(IETF)\footnote{\url{http://www.ietf.org}} as document
+\textit{RFC793}~\cite{rfc793}.

+\subsection{SUT}
+%3,4
+The \textit{System under test} (SUT) is a
+Java\footnote{\url{http://www.java.com}} TCP driven echo server that executed
+on a virtualized Ubuntu system\footnote{\url{http://www.ubuntu.com}} running on
+the Linux kernel\footnote{\url{http://www.kernel.org}} version $3.13$. To test
+the error behaviour custom iptables output policies have to be
+set Listing~\ref{listing:iptables}. This is needed because the kernel by default 
+closes all connections from unknown sources and the manually created TCP 
+packets used in testing the implementation are from a source unknown to the 
+kernel.
 
-%4. The Specification
-The \textit{SUT} will be tested to a subset of the standard defined by
-\textit{Internet Engineering Task Force} in \textit{RFC793}~\cite{rfc793}.
+\begin{lstlisting}[label={listing:iptables},caption={settings iptables}]
+Chain OUTPUT (policy ACCEPT)

+ACCEPT	tcp	--	anywhere	anywhere	tcp flags:PSH/PSH

+\subsection{Risks}

+Risks can be divided into two categories. Project risks and Product risks.
