Info

In this part . . . W ell, this book has covered everything from nontechnical hacks to network and mobile hacks to operating system hacks. What I haven’t yet covered are the applications that run on top of all this, database servers, and the storage systems that ensure the data is available when we need it. The first chapter in this part covers various messaging hacks and countermeasures affecting 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. Finally, this part covers attacks against database servers and storage systems. It covers both structured data found in various database systems and unstructured data, otherwise known as network files.

Why? Well, from my experience, messaging software — both at the server and client level — is vulnerable because network administrators often believe that firewalls and antivirus software are all that’s needed to keep trouble away, or they simply forget about securing these systems altogether. In this chapter, I show you how to test for common e-mail and VoIP issues. I also outline key countermeasures to help prevent these hacks against your systems. Introducing Messaging System Vulnerabilities Practically all messaging applications are hacking targets on your network. Given the proliferation and business dependence on e-mail, just about anything is fair game. Ditto with VoIP. It’s downright scary what people with ill intent can do with it. With messaging systems, one underlying weaknesses is that many of the supporting protocols weren’t designed with security in mind — especially those developed several decades ago when security wasn’t nearly the issue it is today. The funny thing is that even modern-day messaging protocols — or at
