Zero Trust
A security model that treats no network as inherently safe, verifying identity, device health, and authorisation for every request rather than trusting anything inside a perimeter.
The old model trusted the office LAN and guarded the edge. Remote work, cloud services, and unmanaged devices dissolved that boundary, so zero trust re-anchors control on identity and device posture, with least-privilege access granted per resource and per session.
In practice it arrives incrementally: MFA, device compliance policies, network segmentation, per-application access instead of full VPN, and continuous logging. Each step stands on its own, which is why it belongs on a roadmap rather than in a single project.

- MFA
- Authentication requiring two or more independent factors — something you know, have, or are — so a stolen password alone does not grant access.
- Entra ID
- Microsoft's cloud identity service — formerly Azure Active Directory — which authenticates users and devices and enforces access policy across Microsoft 365 and connected applications.
- VLAN
- A logical network segment on shared physical switching, used to isolate device groups — cameras, AV, guest Wi-Fi, corporate data — from each other.
- Endpoint Security
- Protection on the device itself that detects malicious behaviour, contains it, and preserves the forensic trail — going beyond signature-based antivirus.
