Supply Chain Security: Preventing Software and Hardware Breaches

Supply Chain Attack Categories

Supply chain attacks are often categorized into two major vectors:

• Software Component Compromise (The Digital Vector): An attacker compromises the build pipeline (CI/CD) or repository of a vendor and injects malware into a software artifact, package, or update. This poisoned update is then distributed to all customers.
• Hardware/Firmware Compromise (The Physical Vector): An attacker modifies hardware components or firmware at any stage before the product reaches the customer (e.g., during manufacturing or distribution). This provides a persistent backdoor at the lowest level of the operating system.

How to Prevent Supply Chain Attacks

• Adopt Comprehensive Third-Party Risk Management: Covering the entire risk lifecycle for all vendors: due diligence, continuous monitoring, and structured off-boarding.
• Vendor Compliance: Ensure each of your third-party vendors are compliant with the strictest of cybersecurity standards as outlined in your Third-Party Risk policy.
• Access Scrutiny: Enforce strict Zero Trust for all third-party access, ensuring brokered, tightly scoped, and continuously monitored connections.
• Mandatory MFA: Require the vendor to use MFA for all their employees accessing your data or systems.
• Micro-segmentation: Isolate vendor systems via micro-segmentation to prevent lateral movement of attackers to corporate resources if a vendor system is compromised.
