Chapter 4: System Configuration
In this chapter, we will learn more about system configuration and administration, adding users and groups, authenticating on LDAP servers, managing certificates, changing some advanced operating system settings, and how to back up all system configurations.
As we already learned, OPNsense is a complete security platform with a great framework to manage the operating system it runs on – FreeBSD. We will continue exploring WebGUI and learn how to perform some system administration tasks on it. We are going to create users, groups, and certificates, see the steps to add an external authentication server, change some system settings for testing, and perform backup and restore tests. In this chapter, we will look at the following topics:
- Managing users and groups
- External authentication
- Certificates – a brief introduction
