What term describes the TSA's evolving security focus in recent years?

The term that best describes the TSA's evolving security focus in recent years is risk-based security. This approach represents a shift from a one-size-fits-all method to a more nuanced strategy that prioritizes resources and attention towards higher-risk threats, rather than uniformly applying the same level of scrutiny to all passengers and baggage. By identifying and assessing potential risks, TSA aims to enhance airport security measures while streamlining processes for low-risk individuals. This method also fosters a more effective allocation of resources, allowing for increased efficiency within the security screening process while maintaining safety and security standards. The emphasis on risk-based security reflects a broader trend in safety and security practices across various sectors, where tailored strategies are implemented based on specific threats and vulnerabilities.
