NCSC Cyber Check: supply-chain security

Organisations depend heavily on suppliers and partners. The Dutch National Cyber Security Centre therefore gives explicit attention to supply-chain security. Understanding dependencies is now a basic requirement for resilience because a chain is only as strong as its weakest link.

Explanation

Supply-chain security examines which suppliers can access data and systems and how effectively they secure their own environments. A cyber check or supply-chain risk assessment maps these dependencies and weaknesses, including reliance on fourth parties.

Risk

Attackers choose the path of least resistance. A weaker supplier or software package can become the route into the organisation. SolarWinds and Kaseya demonstrated how one compromised link can affect hundreds of organisations through a trusted channel.

Points to check

• A current inventory of suppliers and their access.
• Contractual security and notification requirements.
• Clear incident procedures with suppliers.
• Periodic assessment and monitoring of third parties.

Approach

Start with a supply-chain risk assessment and translate findings into supplier inventories, contractual controls and periodic validation through penetration-test reports and audits. Combine this with segmentation and strict external access controls, and keep the inventory current as integrations and permissions change.

Conclusion

Supply-chain security starts with visibility. Understanding suppliers and their risks enables targeted control and prevents hidden dependencies from determining the organisation's resilience.
