For every action, there is an equal and opposite malfunction. While I am an advocate for system hardening, it must be done bearing the context and business needs in mind. Simply applying the latest firmware and patches looks like a good idea in practice, but doing so blindly and without planning to understand the pros and cons can be more of a hindrance than a help. The same holds true for disabling and removing services, installing new tools and taking a draconian approach to policies. Sometimes you break more than you fix, ending up doing the hackers job for them.
