Network and Information Systems Diagram

A diagram of each network and information system, which KSRA requires the entity to keep and update whenever the system changes.

KSRA

The Cybersecurity Requirements Description (KSRA, Lithuania's NIS2 implementing rules) requires diagrams of all network and information systems, updated whenever the systems change. The diagrams are prepared together with the system description; the requirements may be set out in one or several documents (KSRA point 3).

Under KSRA, the diagrams must include:
  • ● a diagram of each network and information system (KSRA point 47, Table 3, row 21);
  • ● diagrams updated whenever a system changes (KSRA Table 3, row 21).

The logical infrastructure diagram is described separately.
