+The product risks for the SUT are significant because misbehaviour of the SUT
+could have potential large consequences. The key characteristics of TCP are
+integrity and reliability~\cite{rfc793}, these characteristics cease to exist
+when the implementation is faulty.
+
+Because TCP is a core functionality of a networking capable system it is
+crucial that the TCP implementation functions according to the specification.
+Several critical systems could rely on the correct functionality of the TCP
+implementation. A failure in the SUT could therefore have extensive
+consequences. Even more so since TCP is a computer-to-computer protocol, which
+leaves no room for ambiguity, which could be solved in a computer-to-human
+protocol.
