Base Library-level password protection

LaurieF — Thu, 12 Jul 2018 23:50:03 GMT

I'm setting up a proof-of-concept mini-bijou-datamartette. Because the source Microsofty tables are quite sensitive, I must retain security while I go about my investigation phase.

I don't have access to Management Studio (although I'm working on it) and the tables aren't registered with metadata, so I'm cutting my code by hand. It's not ideal, but it's just the way things are.

When I bring the staging data over from the source, can I code a Base-engined libname with a read and write passwords over every dataset, or do I have to apply the passwords individually to each target dataset? If the latter I don't really mind, but it'd be easier if I could apply them higher up.

Ngā mihi nui,

Laurie

I don't see anything on the libname that indicates this is possible. That doesn't mean it doesn't exist though.

Here's a macro approach that you can use if desired.



%macro lockdown(lib=, datain=, pw=, alter=, read=, write=);

proc datasets lib=&lib.;
modify  &datain. (pw=&pw alter=&alter read=&read write=&write);
run;quit;

%mend;

%let lib=demo;

data check;
length str $200.;
format str $200.;
set sashelp.vtable (keep= libname memname);
where libname=upcase("&lib");
str = catt('%lockdown(lib= ', libname, 
                    ', datain=', memname,
                    ', pw=', 'Password1',
                    ', alter=', 'Password2',
                    ', read=', 'Password3',
                    ', write=', 'Password4',
                    ');');
*call execute(str);
run;

Thanks, Reeza! Nicely done. I was thinking along those lines but had been putting it off. Having it a library level would be handy though.

In a perfect world I'd get metadata to control it...oh well.
