For controlling access to the read/write variables and commands, see  
"man upsd.users". As mentioned, if you want to prevent someone from  
reading status, you would need to firewall the NUT port. (The  
upsd.users construct exists because the notion of system userids is  
very specific to a single system, so there needs to be a way to  
specify rights for remote connections.)

There is a discussion of how things work in "man upsmon", but  
basically, you start it as root, and it keeps a root-privileged  
process around that listens to a pipe from the unprivileged process.
