Well, this book has covered all the essential security tests from the nontechnical to the network and on to mobile devices and operating systems. What I haven’t yet covered are the applications that run on top of all this as well as database servers and storage systems that ensure the data is available when we need it.

The first chapter in this part covers various messaging system hacks and countermeasures for e-mail and Voice over IP (VoIP) systems. Next, this part looks at web exploits, along with some countermeasures to secure websites and applications from the elements.

It covers both structured data found in various database systems and unstructured data, otherwise known as files scattered across the network waiting to be exploited.
