True, most services will be database providers, and most of the data is 
(semi) public.
So access control on who is allowed to read the data does not need to be 
highly secure.
However, access control on who is allowed to change the data needs to be 
more secure.

In addition some services may allow control over remote instruments, 
telescopes rovers etc.
For example see  
http://robotics.jpl.nasa.gov/people/jnorris/WITS-IEEEAS00.pdf
" ... (the system) was used for generating command sequences for the 
lander's robotic arm and camera ...."
In which case, these services will need a much higher level of access 
control and security.

We are struggling to implement a single signon system that meets all of 
these conflicting requirements.
