Just because >your root doesn't mean your root in MySQL be aware that for a sufficiently clever administrator, there is no meaningful defense in windows, unix, or linux. the client programs you have written must have access; there must be access to the system catalog. unless you are using a properly set up TCP over SSL connection to get to the database, your clients are vulnerable to a man-in-the-middle attack. it takes a program that sits passively in the connection collecting interesting data until it gets what it needs. unencrypted data residing in RAM or in swap space is at risk at all times. the sole purposes of the windows security "features" you are depending on are to comfort PHBs and discomfit the inept. they don't really work. richard ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
