Written to be a practitioner's tool, it will show you how to dissect network packets and gives you reliable strategies for defending against a variety of threats--including network attacks, crimeware, malware, and the most-prevalent malicious traffic--and trains you on the software used by the top experts in the field to implement your unique plan, including Wireshark, Networkminer, Nmap, Metasploit, and more. Step-by-step instruction begins with explaining how to accurately assess your network's security and establish processes to test penetration. Keep your security strong by setting up your own security-testing lab inside where you can simulate attacks in isolation to observe how systems are targeted and to customize better defenses to stop them
