As a thorough reference, pfSense Essentials covers installation and basic configuration through advanced networking and firewalling with the popular FreeBSD-based pfSense open source firewall and router distribution.  The book includes setting up captive portals and MAC filtering, DHCP services, IPv6 autoconfiguration, multi-WAN routing, caching DNS, Dynamic DNS, high availability and redundant firewalls, port forwarding and network address translation, virtual LANs, traffic shaping and QoS, IPsec, L2TP, OpenVPN, wireless access points, time-scheduled packet filtering, and much more.  It describes the web-based interface for backups, system upgrades, log management, installing add-on packages, graphical reports and analyzing network and system activity, and advanced firewall tunings, as well as the text console interface.  Authored by BSD Unix and QA expert, Jeremy C.  Reed, pfSense Essentials is a detailed guide for common security and networking tasks using pfSense 2.4.4 with older and newer features.

In this book, you will gain extensive hands-on experience installing and configuring a firewall. You will also learn how to allow access to key Web services while maintaining your organization's security, as well as how to implement firewall-to-firewall virtual private networks (VPNs). You will learn how to build a firewall to protect your network; provide access to HTTP and FTP services on the Internet, and implement publicly accessible servers without compromising security. Furthermore, throughout the book, extensive hands-on examples provide you with practical experience in establishing security with firewalls. Examples include, but are not limited to: Installing and configuring Check Point FireWall-1; scanning to validate configuration using ISS Internet Scanner; configuring the firewall to support simple and complex Web services; setting up a packet filtering router; enhancing firewall configurations to support split-DNS; authenticating remote users; and protecting browsers and servers with a proxy-based firewall. · Install and configure proxy-based and stateful-filtering firewalls· Protect internal IP addresses with NAT and deploy a secure DNS architecture· Develop an Internet/intranet security policy to protect your organization's systems and data· Reduce your susceptibility to an attack by deploying firewalls, data encryption and decryption and other countermeasures

Tough, resourceful and ruthless, ex-SAS trooper Nick Stone is now working for the intelligence service on deniable operations. And is desperately in need of cash. When he is offered a lucrative freelance job, Stone thinks his problems are over. All he needs to do is kidnap a Russian mafia warlord. And so Stone is thrust into the grim underworld of Estonia, with unknown aggressors stalking the Arctic landscape. Russia has launched a cyber-espionage attack, hacking into the West’s most sensitive military secrets. Stone must stop them. But the mafia are waiting in the wings with their own chillingly brutal solution... ‘Other thriller writers do their research, but McNab has actually been there’ Sunday Times

This new edition of Volume 1 covers the latest IPng development and information. The text discusses security in TCP/IP environments and firewall designs as well as bridges and routers, presenting routing architectures for large and small internets. It also explains TCP transport services.

This book describes the design and implementation of the BSD operating system--previously known as the Berkeley version of UNIX. Today, BSD is found in nearly every variant of UNIX, and is widely used for Internet services and firewalls, timesharing, and multiprocessing systems. Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; systems programmers can learn how to maintain, tune, and extend the system. Written from the unique perspective of the system's architects, this book delivers the most comprehensive, up-to-date, and authoritative technical information on the internal structure of the latest BSD system. As in the previous book on 4.3BSD (with Samuel Leffler), the authors first update the history and goals of the BSD system. Next they provide a coherent overview of its design and implementation. Then, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing the system's facilities. As an in-depth study of a contemporary, portable operating system, or as a practical reference, readers will appreciate the wealth of insight and guidance contained in this book. Highlights of the book: Details major changes in process and memory management Describes the new extensible and stackable filesystem interface Includes an invaluable chapter on the new network filesystem Updates information on networking and interprocess communication
