A Final Thought
If you learn only one thing from this book, it should be this:
There is simply no substitute for applications that employ secure defaults.
Do not rely on administrators applying security patches or turning off unused features. They will not do it, or they do not know they have to do it, or, often, they are so overworked that they have no time to do it. As for home users, they usually don t know how to apply patches or turn off features.
Ignore this advice if you want to stay in security-update hell.
Ignore this advice at your peril.
