Security

There are several levels of access control to logger commands, although "levels" is perhaps not the best word, as more than one can apply:

1. Open commands can be executed without restriction.

2. Unsafe commands are those which the logger will not execute if logging is in progress. For example, the sampling period cannot be changed in the middle of a deployment. Reading parameters is always available.

3. Protected commands are those which might be considered 'dangerous'; for example, clearing the memory. These have a safety guard on them; see the permit command.
