secure as a $2.49 bicycle lock.
If you want better security you can implement Access Workgroup Security.

Print it out; read it cover to cover, CAREFULLY.
Get a good night's sleep.
Read it AGAIN, even more carefully!
Follow the instructions scrupulously. It's VERY easy to mess up security, and
it's complex.
If you're really concerned about the security of data, be aware that workgroup
security can be cracked, and techniques for doing so are available on the
internet.
And it's been removed from the new format databases in 2007.
For true database security you'll need to move your data to a client-server
platform such as SQL/Server, and secure it there. Again, not a trivial
exercise!
