Which action must occur within 24 hours of detecting a deviation from the CSP?

The requirement to notify the Program Security Officer (PSO) and Security Authority Official (SAO) within 24 hours of detecting a deviation from the Compliance Security Plan (CSP) is crucial because timely communication ensures that any deviations are promptly addressed to mitigate potential impacts on security. The PSO and SAO play key roles in overseeing and managing security protocols and are responsible for evaluating the implications of any identified deviations. Early notification allows for a rapid response to reassess security measures, determine the cause of the deviation, and decide on appropriate corrective actions to safeguard sensitive information and maintain compliance with established security standards.

Other options, such as documentation of financial impact or completion of a risk analysis, are important but do not typically require immediate action within such a tight timeframe. Implementation of new security measures might follow but isn't necessarily a priority action immediately after a deviation is detected. The focus within 24 hours should be on alerting the appropriate authorities to assess and address the situation appropriately.
