As with most security matters, the first thing to consider is what are you protecting from whom? You don't need a Chubb lock to secure the dustbin! Are you a manager of a janitorial company and you don't want just anyone wandering thru db where you have everyone's salary information? Or are you wanting to secure a db where multi-million dollar formulas are stored? It makes a big difference. And before considering "full Access security" be warned of what has always seemed to me to be a rather strange feature of Access; once you apply "Access" security to one db, it applies to all your Access dbs!
