A telecoms service may depend on multiple systems and external providers. Certification is useful only within its stated scope; a claimed reduction in breaches needs evidence that is separate from the certificate.
Questions to follow in an audit
- Which dependencies are included in the service risk assessment?
- How are supplier access and responsibilities reviewed?
- Who evaluates incidents affecting connected services?
Connect the records with practice
Follow a service dependency through its owner, supplier arrangements, access review and records from an incident or exercise.
These are illustrative audit trails, not findings about a named organisation, technical instructions or a guarantee of a particular result. The appropriate evidence depends on the activities, risks and agreed scope. The organisation remains responsible for its operations and legal obligations.
