|About the Book|
Nmap, or Network Mapper, is a free, open source tool that is available under the GNU General Public License as published by the Free Software Foundation. It is most often used by network administrators and IT security professionals to scan corporate networks, looking for live hosts, specific services, or specific operating systems. Part of the beauty of Nmap is its ability to create IP packets from scratch and send them out utilizing unique methodologies to perform the above-mentioned types of scans and more. This book provides comprehensive coverage of all Nmap features, including detailed, real-world case studies.• Understand Network ScanningMaster networking and protocol fundamentals, network scanning techniques, common network scanning tools, along with network scanning and policies.• Get Inside NmapUse Nmap in the enterprise, secure Nmap, optimize Nmap, and master advanced Nmap scanning techniques.• Install, Configure, and Optimize NmapDeploy Nmap on Windows, Linux, Mac OS X, and install from source.• Take Control of Nmap with the Zenmap GUIRun Zenmap, manage Zenmap scans, build commands with the Zenmap command wizard, manage Zenmap profiles, and manage Zenmap results.• Run Nmap in the EnterpriseStart Nmap scanning, discover hosts, port scan, detecting operating systems, and detect service and application versions• Raise those FingerprintsUnderstand the mechanics of Nmap OS fingerprinting, Nmap OS fingerprint scan as an administrative tool, and detect and evade the OS fingerprint scan.• “Tool” around with NmapLearn about Nmap add-on and helper tools: NDiff--Nmap diff, RNmap--Remote Nmap, Bilbo, Nmap-parser.• Analyze Real-World Nmap ScansFollow along with the authors to analyze real-world Nmap scans.• Master Advanced Nmap Scanning TechniquesTorque Nmap for TCP scan flags customization, packet fragmentation, IP and MAC address spoofing, adding decoy scan source IP addresses, add random data to sent packets, manipulate time-to-live fields, and send packets with bogus TCP or UDP checksums.
