Bottom line: Supply-chain attacks cannot be completely prevented, but their impact can be significantly limited through systematic risk mitigation and resilience measures.
Supply-chain attacks are becoming increasingly attractive to cybercriminals because security vulnerabilities in supply chains can be deliberately exploited. While organizations cannot reduce their vulnerability to zero, they should systematically pursue damage mitigation.
Attackers deliberately exploit weaknesses in supply chains because they often encounter lower defensive measures there than at the highly secured target organizations themselves. Supply-chain attacks have thus become a preferred attack pattern that is not limited to individual industries.
For a CISO, the key insight is: complete prevention is not a realistic goal. Instead, the strategy should be geared toward reducing the impact of supply-chain compromises and enabling faster response.
This includes measures such as network segmentation, continuous monitoring of manufacturers and suppliers, dependency mapping, and incident-response plans specifically designed for supply-chain scenarios. Documented supplier monitoring is also required in accordance with NIS2 requirements. The focus is not on defense at all costs, but on resilience and rapid recovery.
