Level 50 is better security than level 10 but does your software work on the 
highest OS/400 security settings?  Probably not.

You should start with the basic IBM manuals on OS/400 security, that talk 
precisely about risks from PC connections to software designed for twinax era 
& what to do to protect yourself, but unfortunately much of the IBM security 
advice assumes you purchased corporate software from a vendor that cares 
about security.  

What we need are documents that tell us what is the best security we can get 
with an individual package that thousands of enterprises are running which is 
designed to mess up OS/400 security efforts.  One guide for each of the 
packages, so that users of those packages know what they can do, instead of 
being frustrated at IBM advice to do things that will cause the packages to 
quit working.

If you do not have access to the standard IBM manuals that come with every 
AS/400, I suggest you visit 

You might also check the archives of this discussion group

there have been extensive discussions of various AS/400 Security Challenges.
As my time permits, I have been revieing our own Security to see what is 
practical to improve, which is leading to some tinkering with System Values 
... I could send you off-line some cut & paste from my security learning 
curve if you interested.

Do you have software that is based on certain file layout definitions, such 
that if PC users were to change the file layouts the software would break?  
Do the PC users who are doing file transfers know that, or is their level of 
400 literacy such that you just have to cross your fingers?
