<p class="MsoNormal"><span style="mso-fareast-language:EN-US">About CYSAT, I believe Mathieu Bailly (promoter from CYSEC) is very enthusiastic about the whole subject. I got to know him before COVID when he approached ESA to enter the space business. However,
not sure I would make the claims he makes about the size and importance of the event
</span><span style="font-family:"Segoe UI Emoji",sans-serif;mso-fareast-language:EN-US">😊</span><span style="mso-fareast-language:EN-US">. His target audience is mainly ‘new space’. My main goals are to continue raising awareness on space system security and
promote CCSDS standards.<o:p></o:p></span></p>

security engineers. It might not be perfect, but I do not know of any other reference at a similar level on the subject.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-family:"Aptos",sans-serif">Hi Ignacio,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-family:"Aptos",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-family:"Aptos",sans-serif">Congratulations on getting their attention and being invited to give a tutorial. I think this is a great opportunity for you and for CCSDS. According to their site the focus is
“</span><span lang="EN-US">CYSAT is the biggest worldwide event entirely dedicated to cybersecurity for commercial space applications.</span><span lang="EN-US" style="font-family:"Aptos",sans-serif">” I’m assuming that largely means near Earth and commercial,
but maybe there is room to squeeze in civilian space, exploration, and looking out to the Moon?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-family:"Aptos",sans-serif"><o:p> </o:p></span></p>
<p class="p1"><span lang="EN-US" style="font-size:11.0pt;font-family:"Aptos",sans-serif;color:windowtext;mso-ligatures:standardcontextual">There’s a new-ish NIST standard, NIST SP800-160-v1r1, “Engineering Trustworthy Secure Systems” (</span><span lang="EN-US"><a href="https://doi.org/10.6028/NIST.SP.800-160v1r1">https://doi.org/10.6028/NIST.SP.800-160v1r1</a></span><span lang="EN-US" style="font-size:11.0pt;font-family:"Aptos",sans-serif;color:windowtext;mso-ligatures:standardcontextual">).
After reading it I believed that they had missed some important points relating to all of the different viewpoints where cybersecurity needed to be addressed in architecting these systems. I created a PPT file based on our recent RASDS work, attached here,
that I sent to the lead author, Mark Winstead. He agreed that these materials offered some value and would be considered in an update. I’m attaching it here for your consideration since it provides a view of the environment within which SDLS has a direct
role.<o:p></o:p></span></p>

<p class="p1"><span lang="EN-US" style="font-size:11.0pt;font-family:"Aptos",sans-serif;color:windowtext;mso-ligatures:standardcontextual">Look for the main relevant viewpoints: functional, information, connectivity, protocol, and enterprise (pgs 14, 19, 25,
30, and 35) and then look for the security topics pages associated with each viewpoint (pgs 17, 22, 28, 33, and 38).
