summary of the rationale (less than one page) and 
for further detail provide a reference that is easily and publicly available.

security sections should be present. Any

CESG E-Poll Identifier:  CESG-P-2021-11-004 
Approval to publish CCSDS 350.1-G-3, Security 
Threats against Space Missions (Green Book, Issue 3)
Results of CESG poll beginning 26 November 2021 and ending 10 December 2021:

                 Abstain:  0 (0%)
Approve Unconditionally:  3 (75%) (Merri, Shames, Aguilar Sanchez)
Approve with Conditions:  1 (25%) (Wilmot)
Disapprove with Comment:  0 (0%)
CONDITIONS/COMMENTS:

     Jonathan Wilmot (Approve with 
Conditions):  3.4.10 UNAUTHORIZED ACCESS should 
also address crew interfaces which do not 
interface through ground systems. An issue to 
discuss is crew inability to safe themselves when 
inappropriate  security measures lock them out.
Consider adding a Tainted Software section 
similar to 3.4.11 TAINTED HARDWARE COMPONENTS. Same logic could apply.

Consider adding some discussion on how 
“Probabilities” were determined in treat analysis 
tables. That would be very useful to the target audience.
Consider adding some discussion on time 
distribution. Accurate clocks are key to 
navigation and communications protocols such as 
DTN.  Missions have proposed NTP for vehicle to 
vehicle time synchronization which brings issues 
with jumps in time forward/backwards, time 
convergence latency, 
 which could be threats either intended or unintended.
