Password protect backend

[Sigurd Bruteig]

Hi!
I have a passwordprotect ed backend. I just realised that you can download a
cracking application that can crack a password with up to 18 signs. I have
tryed it and it works. My question is: is there any other software capable
to crack password with more than 18 signs, and how long can a password be in
Access.

Re: Password protect backend

There is software, it appears, that can break Access security no matter what
length of password you have used. Some of it does not even require that you
have the MDW file, only the database itself. If you search a little, and "a
little" is the operative description, you'll find a free download that will
break security on an Access 97 database, giving you the owner's name and SID
(or is it PID or ???) so you can do most anything.

What I've not heard about, is anyone who thought it worth their while to try
to recreate source code from the compiled (actually "tokenized" ) code in an
MDE. But the concensus of experienced Access developers is that they could
recreate most any Access application in a short while once they have seen
the User Interface demonstrated, as in a trial download, so "breaking the
code" would be, in fact, a waste of time and effort.

If your data is really important, and worth protecting, put it in a server
database and use server and server DB security, then use an Access client
application as the front end to use it. That way, you avoid giving a
potential cracker easy access to take your data and carry it away to his/her
own desktop where he/she can break into it at leisure.

That said, most of the clients for whom I have done work have adequate
checking of their personnel, and adequate physical security, that they have
found Access security to be sufficient. The ones who did not find that to be
sufficient thought protecting their data was worth the cost of putting it in
a server DB.
