CISM study material · question 656 of 1000

Who must sign the memorandum of understanding for an interconnection, and why does it matter?

  1. The system administrator, who operates the connection from day to day and who would have to carry out any disconnection of it in the end himself
  2. An organisational official, typically the authorising official, so the instrument is enforceable by either party
  3. The security officer, who assessed the risk that the connection introduces to each of the two systems that are joined by it
  4. The contracting officer, who manages the commercial terms under which the connection is provided and is paid for each year
Show the answer

Answer: B. An organisational official, typically the authorising official, so the instrument is enforceable by either party

SP 800-100 requires signature by an organisational official, usually the authorising official, because that is what makes the memorandum something either party can enforce.
