The official guide to the Nmap Security Scanner, a free and open source utility used by millions of people, suits all levels of security and networking professionals.
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 Scanning Master networking and protocol fundamentals, network scanning techniques, common network scanning tools, along with network scanning and policies. • Get Inside Nmap Use Nmap in the enterprise, secure Nmap, optimize Nmap, and master advanced Nmap scanning techniques. • Install, Configure, and Optimize Nmap Deploy Nmap on Windows, Linux, Mac OS X, and install from source. • Take Control of Nmap with the Zenmap GUI Run Zenmap, manage Zenmap scans, build commands with the Zenmap command wizard, manage Zenmap profiles, and manage Zenmap results. • Run Nmap in the Enterprise Start Nmap scanning, discover hosts, port scan, detecting operating systems, and detect service and application versions • Raise those Fingerprints Understand 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 Nmap Learn about Nmap add-on and helper tools: NDiff--Nmap diff, RNmap--Remote Nmap, Bilbo, Nmap-parser. • Analyze Real-World Nmap Scans Follow along with the authors to analyze real-world Nmap scans. • Master Advanced Nmap Scanning Techniques Torque 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.
Nmap is a well known security tool used by penetration testers and system administrators. The Nmap Scripting Engine (NSE) has added the possibility to perform additional tasks using the collected host information. Tasks like advanced fingerprinting and service discovery, information gathering, and detection of security vulnerabilities. "Nmap 6: Network exploration and security auditing cookbook" will help you master Nmap and its scripting engine. You will learn how to use this tool to do a wide variety of practical tasks for pentesting and network monitoring. Finally, after harvesting the power of NSE, you will also learn how to write your own NSE scripts. "Nmap 6: Network exploration and security auditing cookbook" is a book full of practical knowledge for every security consultant, administrator or enthusiast looking to master Nmap. The book overviews the most important port scanning and host discovery techniques supported by Nmap. You will learn how to detect mis-configurations in web, mail and database servers and also how to implement your own monitoring system. The book also covers tasks for reporting, scanning numerous hosts, vulnerability detection and exploitation, and its strongest aspect; information gathering.

How secure is your network? The best way to find out is to attack it, using the same tactics attackers employ to identify and exploit weaknesses. With the third edition of this practical book, you’ll learn how to perform network-based penetration testing in a structured manner. Security expert Chris McNab demonstrates common vulnerabilities, and the steps you can take to identify them in your environment. System complexity and attack surfaces continue to grow. This book provides a process to help you mitigate risks posed to your network. Each chapter includes a checklist summarizing attacker techniques, along with effective countermeasures you can use immediately. Learn how to effectively test system components, including: Common services such as SSH, FTP, Kerberos, SNMP, and LDAP Microsoft services, including NetBIOS, SMB, RPC, and RDP SMTP, POP3, and IMAP email services IPsec and PPTP services that provide secure network access TLS protocols and features providing transport security Web server software, including Microsoft IIS, Apache, and Nginx Frameworks including Rails, Django, Microsoft ASP.NET, and PHP Database servers, storage protocols, and distributed key-value stores
