This invention relates to the field of broadcast television security technology, specifically disclosing a proactive defense method for broadcast security based on
risk profiling. By constructing a three-tiered collaborative responsibility decoupling architecture, the broadcast duty team is divided into three roles: A (dedicated to
signal monitoring and situational awareness), B (dedicated to
business process management), and C (dedicated to overall decision-making), achieving clear responsibilities and efficient
collaboration. A focus-based rotation mechanism is established, mandating the interchange of A and B roles to reset personnel focus and create complementary
verification. A multi-dimensional hidden danger
database is constructed, and a weighted risk priority coefficient model is used to quantitatively assess hidden dangers, generating contextualized
risk profile reports. Risk profiles are transformed into explicit broadcast control front-end instructions, driving focused monitoring and process operations, forming cross-
verification, and new data is fed back to iteratively optimize the model, forming a proactive defense
closed loop. This invention can improve personnel duty efficiency and
risk identification accuracy, reduce broadcast security risks, and achieve long-term security for
broadcasting.
