Questions and answers

What is the goal of Mission Assurance under SLD45I10-2401?

The goal of Mission Assurance (MA) is to protect or ensure the continued function and resilience of mission capabilities and assets including personnel, equipment, facilities, networks, information and information systems, infrastructure, and supply chains critical to the performance of SLD 45 mission-essential functions (MEFs) in any operating environment or condition. (paragraph 1)

How does SLD 45 use Mission Assurance?

The SLD 45 uses MA as the structure and process to protect or ensure the continued function and resilience of capabilities and assets by refining, integrating and synchronizing the aspects of security, protection, and risk management programs that directly relate to mission execution. MA is an integrative framework – not a single policy or program – that emphasizes defensive, resilience and reconstitution actions and prioritizes efforts to reduce risks from a range of complex threats and hazards. (paragraph 1)

Who is ultimately responsible for risk management decisions affecting SLD 45 assets?

The Space Launch Delta 45 Commander (SLD 45/CC) is ultimately responsible for risk management decisions affecting SLD 45 assets, processes, and capabilities. (paragraph 2)

What must information sharing be based on?

Information must be safeguarded and secured appropriately, based on the sensitivity of the information. It should be shared only with authorized DoD personnel and mission partners with the need-to-know. (paragraph 6)

What classification guidance must MARPAs follow?

All MARPAs will follow the classification guidance prescribed in the Defense Critical Infrastructure (DCI) Line of Effort (LOE) Security Classification Guide (SCG) as well as any additional applicable security classification guidance. (paragraph 6)
