Mastering PacketFence

Network Access Control (NAC) is no longer limited to controlling who can connect to a network. Modern organizations need to identify devices and users, enforce security policies, control access, integrate authentication, isolate non-compliant endpoints, and continuously maintain visibility across wired and wireless networks.

Mastering PacketFence provides a practical, step-by-step guide to understanding, deploying, configuring, securing, troubleshooting, and managing PacketFence 15.2 in real-world network environments.

Starting with networking and NAC fundamentals, the book gradually moves into enterprise deployment and advanced concepts. It explains not only what to configure, but also why the configuration matters and how the different components work together.

• Understand Network Access Control and how NAC fits into enterprise security
• Learn PacketFence architecture, components, workflows, and deployment models
• Install and configure PacketFence in a practical environment
• Configure wired and wireless network access control
• Understand and implement 802.1X authentication
• Work with RADIUS, FreeRADIUS, LDAP, Active Directory, and authentication services
• Configure switches, VLANs, DHCP, DNS, and network enforcement
• Implement device registration, profiling, authentication, and authorization
• Create security policies for different users, devices, and network segments
• Handle guest access and captive portal environments
• Understand endpoint compliance and isolation workflows
• Troubleshoot authentication, RADIUS, VLAN, DHCP, DNS, and connectivity problems
• Design NAC environments for scalability and enterprise networks
• Understand high availability and resilience considerations
• Integrate PacketFence with existing network and security infrastructure
• Explore automation and practical operational techniques
• Apply Zero Trust principles to network access control
• Build a structured approach to monitoring, maintenance, and troubleshooting

The book also includes practical examples, configuration guidance, troubleshooting scenarios, network concepts, architectural explanations, and original diagrams to help readers understand how the pieces fit together.
