pfSense 2.x Cookbook. Manage and maintain your network using pfSense - Second Edition

David Zientara

pfSense is an open source distribution of the FreeBSD-based firewall that provides a platform for ?exible and powerful routing and firewalling. The versatility of pfSense presents us with a wide array of configuration options, which makes determining requirements a little more difficult and a lot more important compared to other offerings. pfSense 2.x Cookbook – Second Edition starts by providing you with an understanding of how to complete the basic steps needed to render a pfSense firewall operational. It starts by showing you how to set up different forms of NAT entries and firewall rules and use aliases and scheduling in firewall rules. Moving on, you will learn how to implement a captive portal set up in different ways (no authentication, user manager authentication, and RADIUS authentication), as well as NTP and SNMP configuration. You will then learn how to set up a VPN tunnel with pfSense. The book then focuses on setting up traffic shaping with pfSense, using either the built-in traffic shaping wizard, custom ?oating rules, or Snort. Toward the end, you will set up multiple WAN interfaces, load balancing and failover groups, and a CARP failover group. You will also learn how to bridge interfaces, add static routing entries, and use dynamic routing protocols via third-party packages.

Zadbaj o bezpieczeństwo swojego komputera Poznaj zagrożenia, na jakie narażony jest komputer Naucz się kontrolować dostęp do komputera Stosuj techniki zapewniające bezpieczeństwo w sieci Czy mój komputer na pewno jest bezpieczny? Wiele osób zadaje sobie to pytanie dopiero w momencie, kiedy system zaczyna zachowywać się w podejrzany sposób. Okazuje się wówczas, że skaner wykrywa dziesiątki, a nawet setki wirusów, programy zaczynają działać nieprawidłowo, a z dysku giną ważne dane. Pół biedy, jeśli jest to tylko domowy komputer z prywatnymi plikami. Dużo gorsze skutki może mieć włamanie do firmowej bazy danych lub przechwycenie poufnej komunikacji. Książka "Podstawy ochrony komputerów" to wszechstronne wprowadzenie do najważniejszych zagadnień dotyczących bezpieczeństwa danych i sprzętu. Czytając ją, poznasz zagrożenia, jakie czyhają na użytkowników komputerów, ale także skuteczne techniki ochrony. Nauczysz się kontrolować dostęp do danych, prowadzić efektywną politykę zabezpieczeń, wykrywać i usuwać wirusy oraz zapobiegać przenikaniu ich do systemu. Dowiesz się, jak zapewnić bezpieczeństwo komputera w sieci oraz jak używać szyfrowania do przesyłania poufnych informacji. Przeczytasz też o najnowszych technikach zabezpieczenia bazującego na danych biometrycznych (wzorze siatkówki czy odciskach palców) oraz ochronie sieci bezprzewodowych. Niebezpieczeństwa grożące użytkownikom komputerów Kontrolowanie dostępu do komputera Walka z wirusami Prowadzenie skutecznej polityki zabezpieczeń Bezpieczne korzystanie z sieci Szyfrowanie poufnych danych Komunikacja bez ryzyka Zabezpieczenia biometryczne Tworzenie bezpiecznych sieci bezprzewodowych Stosuj skuteczne zabezpieczenia i zapewnij maksymalne bezpieczeństwo swojemu komputerowi!

Practical Industrial Internet of Things Security. A practitioner's guide to securing connected industries

Sravani Bhattacharjee

Securing connected industries and autonomous systems is of primary concern to the Industrial Internet of Things (IIoT) community. Unlike cybersecurity, cyber-physical security directly ties to system reliability as well as human and environmental safety.This hands-on guide begins by establishing the foundational concepts of IIoT security with the help of real-world case studies, threat models, and reference architectures. You’ll work with practical tools to design risk-based security controls for industrial use cases and gain practical knowledge of multi-layered defense techniques, including identity and access management (IAM), endpoint security, and communication infrastructure. You’ll also understand how to secure IIoT lifecycle processes, standardization, and governance. In the concluding chapters, you’ll explore the design and implementation of resilient connected systems with emerging technologies such as blockchain, artificial intelligence, and machine learning.By the end of this book, you’ll be equipped with the all the knowledge required to design industry-standard IoT systems confidently.
