I can respond to that question.
In addition to enhanced physical security and access control measures, all policies at the national microbiology laboratory and the agency were revised. These are secret-level facilities requiring clearances under the Human Pathogens and Toxins Act. There is continual training and review of our guard services, as well as our personnel. We have strengthened protocols for deliveries in shipping and receiving, including mandatory controls around documentation and verification of infectious materials. There are requirements for material transfer agreements and collaborative research agreements, and enforcement of their use.
Comprehensive threat and risk assessments for the physical and IT environments have been undertaken to ensure that all of our security measures are complete and up to date. In addition, we have updated our policy on affiliations and collaborations with academic, research and health care organizations, and we have a new student hiring policy with additional controls.
These are designed to respond to the threat environment we face.
