Re: User Level Security in Access 2007

In addition to what Tom has said:

For years, those of us who realized the ease with which a determined
cracker 
could get past ULS have been advising that if your data was worth US$150
to 
you (the cost of password recovery software on the Internet) should use a 
server back end for security and that compiling to .MDE would protect your

code.  Now, it turns out that the ULS password recovery code can be had
for 
free, and there is now software, either free or inexpensive, to convert an

..MDE back into a usable .MDB.

With the new ACCDB in Access 2007, access to SharePoint data is
enhanced... 
it's not truly relational, with referential itegrity, but many companies
are 
using it, and finding Access a good front-end, just as it has been for 
server DBs.  And, like server DBs, it has its own data security. There are

additional datatypes, and user interface changes (the latter, you will
have 
to decide for yourself if it is an advantage or disadvantage). I think 
you'll find a longer and more-detailed list of changes at the 
http://office.microsoft.com
website.

ULS has been convenient for keeping users from stumbling over their own 
keystrokes, but that can be coded -- it won't be truly "secure" but will
be 
about as secure as ULS has turned out to be. In fact, one of my earliest 
paying jobs with Access was to implement a "security lite" scheme for just

that purpose, and the client and prime contractor were worried not at all 
that it was relatively easy for a knowledgeable Access user to break.
