A sample answer to question 1

How would you carry out a security risk assessment of a new third-party supplier?

I start by understanding what the supplier will do for us: what data they will hold, what access to our systems they need, how critical the service is and where they operate. That sets the inherent risk tier, which determines the depth of assessment. For a high-risk supplier I issue a tailored questionnaire, such as SIG or a custom set mapped to ISO 27001, and ask for evidence rather than just answers: certificates like ISO 27001 or SOC 2 Type II reports with their scope and exceptions, penetration test summaries, policies, and details of sub-processors. I review the responses, validate them through a call or evidence sampling, and consider external signals such as security ratings from BitSight or SecurityScorecard and any breach history. Findings are scored and recorded with required remediation. Then I agree contractual protections, such as breach notification windows, audit rights and data return, and set a monitoring schedule. The final residual risk goes to the business owner for acceptance.

Common mistake to avoid: Sending the same questionnaire to every supplier; accepting certificates without checking scope
