Your Business Security Depends on Your Partners: Managing Supply Chain Risk

By support@squaretechperth.com.au | Wed, 29-Oct-2025 16:34
Week 3: Supply Chain Risk
 
Introduction
In today’s connected world, your cyber security is only as strong as your weakest supplier. If your vendors, contractors, or service providers have poor security practices, attackers can use them as a gateway into your business.
This Cyber Security Awareness Month, ASD and ACSC are shining a spotlight on supply chain security — a risk every business needs to manage.
Why Supply Chain Attacks Happen
•    Attackers target smaller suppliers to reach bigger organisations
•    Trust relationships mean suppliers often have system access
•    Software updates can be compromised (e.g., SolarWinds attack)
Examples of Supply Chain Risks
•    A managed service provider (MSP) with weak passwords gets hacked — attackers gain access to all their clients
•    A supplier sends an infected attachment — which bypasses normal checks because “it’s from a trusted vendor”
What You Can Do
1.    Vet your suppliers: Ask about their cyber security practices before signing contracts
2.    Add cyber clauses: Require MFA, encryption, and incident reporting from vendors
3.    Review access regularly: Ensure suppliers don’t have more system access than needed
4.    Plan for incidents: Assume a partner could be breached — and know how you’d respond
How Squaretech Perth Helps
We build vendor risk management frameworks for Perth businesses — from simple questionnaires to continuous monitoring.
