  3. Network, firewall and Wi-Fi

A network that keeps things apart.

In many offices, guests, staff, printers, servers and card terminals share one flat network. Segmentation keeps a compromise in one place contained, and a reviewed firewall keeps out what should never get in.

What it covers

Network, firewall and Wi-Fi

Network segmentation

Staff, guest, server, voice and payment networks separated, with rules for what may talk to what.

Firewall review

Rules reviewed, unused and overly broad rules removed, and changes documented.

Secure remote access

VPN or zero trust access with multi factor authentication, replacing exposed remote desktop.

Wi-Fi design

Site surveys, access point placement and secure configuration for staff and guests.

Documentation

Network diagrams, IP plans and configuration backups kept current.

  • PCI DSS v4.0
  • VLAN segmentation
  • Zero trust access
  • Wi-Fi 6

How we do it

  1. Survey

    Current network, rules and coverage reviewed.

  2. Design

    Segmentation, rules and Wi-Fi planned.

  3. Install

    Changes made in planned windows.

  4. Document

    Diagrams and configurations recorded.

Field notes

Worth knowing

PCIDSS

Payment devices need their own space

PCI DSS expects card data environments to be segmented from other systems. Segmentation also shrinks the scope of a PCI assessment.

Questions

Why separate the guest Wi-Fi?

Guest devices are outside your control. Keeping them on a separate network stops them reaching your systems.

How often should firewall rules be reviewed?

At least annually, and whenever systems are added or removed. PCI DSS requires reviews every six months for in scope environments.

Is remote desktop safe to expose to the internet?

No. Exposed remote desktop is a common ransomware entry point. Put it behind a VPN or zero trust access with multi factor authentication.
