I found 3 of my directories ( and subs ... ) had been modified by
the addition of an ACL giving SCA$SERVER full access to all
of the files!! I have not used the Source Code Analyzer.
Do I have a security problem?
The Answer is:
You must have installed DECset's Source Code Analyzer product - it causes
this ACL to be added to all files, whether or not you are using SCA.
