I approve of the "avoid monoculture" notion, in some ways. After all, it *is* an enormous problem that the world is filled with Windows systems that run the same kernels, most of the same drivers, the same MS Office, the same Outlook, and which hence are vulnerable to the varied array of Things That Attack Windows. And "script kiddies" have had a history of analyzing what vulnerabilities Red Hat left in their distribution. A monoculture of Red Hat 7.2 systems isn't all that secure, either. I think we'd be in a "better world," computing-wise, if we had some better diversity of the sort where we had a multiplicity of platforms. MVS, VMS, OS/2, Unix, all have been been meaningful to that end. But I'm not at all sure that security is enhanced simply in the fact of having multiple flavours of databases in the environment. I can only see that being of material assistance once you have gotten to the point where it *isn't* more useful to secure what you already have than it is to introduce brand new components you need to learn to secure. -- let name="cbbrowne" and tld="gmail.com" in String.concat "@" [name;tld];; http://cbbrowne.com/info/wp.html If men can run the world, why can't they stop wearing neckties?
