This Zero Trust series starts with core principles, identity, segmentation, and least privilege. I’ll cover real-world tools like pfSense, 802.1X, IPsec, firewalls, smartcards, and certificate-based authentication. We’ll first explore the theory behind Zero Trust, followed by its practical implementation, the fun part. Although the theory is wordy and a bit.... boring, it's important to understand the principles and how they apply to the implementation of the tech.

To enable VLAN tagging on a Raspberry Pi, install the vlan package with sudo apt install vlan, then load the 8021q kernel module using sudo modprobe 8021q. This setup allows your Raspberry Pi to support 802.1Q VLAN interfaces for use with managed switches and segmented networks.

The Security System detected an authentication error for the server cifs/DomainController. The failure code from authentication protocol NTLM was "The authentication failed since NTLM was blocked (0xc00004189)".
