exists a present or future threat to homeland 
security in the event of disruption, corruption, 
exploitation, or dysfunction to such domain. 
Such research shall consider, to the extent pos-
sible, the following: 
‘‘(i) The vulnerability and resilience of 
relevant supply chains. 
‘‘(ii) Foreign production, processing, 
and manufacturing methods. 
‘‘(iii) Influence of malign economic ac-

function. 
‘‘(B) ADDITIONAL RESEARCH INTO HIGH-

duct additional research into those critical do-
mains, or specific elements thereof, with respect 
to which there exists the highest degree of a 
present or future threat to homeland security in 
the event of disruption, corruption, exploitation, 
or dysfunction to such a domain. For each such 
high-risk domain, or element thereof, such re-
search shall— 
‘‘(i) describe the underlying infra-
structure and processes; 
‘‘(ii) analyze present and projected 
performance of industries that comprise or 
support such domain; 
‘‘(iii) examine the extent to which the 
supply chain of a product or service nec-
essary to such domain is concentrated, ei-
ther through a small number of sources, or 
if multiple sources are concentrated in one 
geographic area; 
‘‘(iv) examine the extent to which the 
demand for supplies of goods and services 
of such industries can be fulfilled by 
present and projected performance of other 
industries, identify strategies, plans, and 
potential barriers to expand the supplier
