Training in Englisch:
NAC (network access control)


In this training the participants will learn about network access control, its standards and implementation.

All technical topics are discussed in detail, from the basics, through the 802.1x technology, to the creation of the secured network.
At the end of this NAC training course, the participants will have a good understanding and will be able to implement NAC in their company infrastructure reliably and independently

Introduction to this NAC (network access control) training


In this training course we not only discuss the theory of RADIUS, AAA and 802.1x but we will also do the things practically.

To make things more interesting and dynamic we will talk about various appliance and solutions. In this training, we will check the open source NAC solution PacketFence and understand how can NAC be implemented using this solution. Moreover, we would also talk about Macmon, which is another established NAC appliance. In the end, we will talk about Cisco identity service engine (ISE) and briefly check the necessary and basic configuration to see how NAC functionality can be achieved with this appliance.


This will not only enable you to expand our knowledge to multiple platform but also enable you to evaluate these solutions and choose what fits best in your network infrastructure.


Network access Control (NAC):

Network access control (NAC), solutions support network visibility and access management through policy enforcement on devices and users of corporate networks LAN. NAC is sometimes also called network admission control.
It is a method of implementation security by restricting the the availability of network resources to only those end device which comply the an organisation’s security policy. NAC in a nutshell is a server that performs authentication of the connecting users/ end device by verifying the their credentials. NAC can be implemented in numerous types of organisations e.g. from corporate to universities and schools, where there are thousand of users with various backgrounds and objectives. With organisations having wide variety of users and growing mobile devices accessing the network brings a lot of threat to the organisation’s network security.

Therefore it is critical to have tools that provide visibility, access control, and compliance capabilities that are required to strengthen your network security infrastructure.


  • Common security issues

  • 802.1x and NAC technology

  • User Authentication

  • Advance terminologies and Protocols: EAP, MAB, RADIUS, AAA etc.

  • RADIUS and NAC configuration with various switch vendors namely Cisco and Huawei. • Practical implementation of NAC on

  • PacketFence

  • Overview of Macmon appliance and its features

  • NAC implementation on Cisco (ISE) with builtin NAC policies and customised policies.


Target group:

The participants already have a basic understanding of IT networks LAN & WAN.

Experienced participants benefit from the imparted depth of knowledge, participants with junior knowledge appreciate the clear explanation of the technical relationships.

All course participants will then receive a certificate of attendance.

Die Schwerpunkte im OPNsense LAB sind:

Parallel führen wir viele Übungen im LAB durch. Die Teilnehmer haben dabei die Möglichkeit, spezielle Anforderungen oder Fragen im LAB zu besprechen.

  • Prüfung der Regeln im Logfile

  • Auswirkungen des Firewall Session Cache Status

  • Mitsniffern von CARP und von IPv6-Router-Advertisements

  • Testen diverser OPNsense-Funktionen

  • Wireshark / tcpdump der aufkommenden Fragen.

Die Teilnehmer bringen idealerweise ihre eigenen Laptops mit und greifen auf die OPNsense-Laborumgebung zu. Sofern gewünscht, können die Teilnehmer ihre eigene virtuelle OPNsense-Umgebung nutzen.

Am Ende des Kurses kann jeder Teilnehmer maßgeblich zur IT-Sicherheit im Unternehmen beitragen und kann darauf zu Recht stolz sein.



Die Teilnehmer haben bereits ein Grundverständnis von IT-Netzwerken.

Erfahrene Teilnehmer profitieren von der vermittelten Wissentiefe, Teilnehmer mit Junior-Wissen schätzen die anschauliche Erklärung der technischen Zusammenhänge.

Alle Kursteilnehmer erhalten im Anschluß ein Teilnahmezertifikat.
