securing Operating Systems

The NSA (No Such Agency) has released guides for securing various operating systems so that private suppliers to the US Government are less likely to supply completely unsecure systems. Or maybe they are bluffing, and want you to follow there advise which will open up subtle holes for them to exploit. Or maybe it is a double bluff, and they know people will think this and so deliberately not follow there advise leaving there systems in the a less secure default state than it could be making there cracking duties easier. Or maybe it is a triple bluff ... head explodes.
