Network Isolation Strategy

LinkedIn Post 7: Network Isolation Strategy

Your building has devices with non-changeable default passwords that can't be replaced immediately.

What do you do?

Option 1: Replace them (expensive, disruptive)

Option 2: Isolate them on a separate network segment

Network isolation means:

• Separate VLAN for non-compliant devices

• Firewall rules restricting who can access them

• Egress filtering preventing them from accessing the wider network

• Monitoring for anomalous behavior

Is this perfect compliance? No. But it's a documented mitigation that shows you've taken PSTI seriously and reduced the risk while planning for replacement.

From a regulatory standpoint, documented risk mitigation beats no documentation at all.
