[Verse 1]
Supply chains weave through shadows, vendors hide their source
Level One assessment starts the criticality course
Basic functions cataloged, essential systems mapped
DIA SCRM TAC guidance keeps our defenses wrapped
[Chorus]
Trust but verify every time
Four levels climbing up the line
TSN processes intertwine
With taxonomy's design
Critical-High-Medium-Low
Risk assessment helps us know
Verify every time, verify every time
[Verse 2]
Level Two digs deeper into mission-critical gear
Dependencies unraveled, threats becoming clear
Technical surveillance networks scan the vendor space
Cross-referencing data points at methodical pace
[Chorus]
Trust but verify every time
Four levels climbing up the line
TSN processes intertwine
With taxonomy's design
Critical-High-Medium-Low
Risk assessment helps us know
Verify every time, verify every time
[Bridge]
Level Three examines compromise scenarios
Single points of failure, cascading portfolios
Level Four investigates the most sensitive domain
National security hangs upon this verification chain
[Verse 3]
DIA TAC coordinates implementation standards
TSN feeds intelligence where taxonomy commands
Real-time monitoring merged with structured classification
Building fortress walls through systematic validation
[Chorus]
Trust but verify every time
Four levels climbing up the line
TSN processes intertwine
With taxonomy's design
Critical-High-Medium-Low
Risk assessment helps us know
Verify every time, verify every time
[Outro]
From basic inventory to the deepest threat review
Methodology protects what defenders must pursue
Trust but verify, the mantra never dies
In supply chain risk management, vigilance is wise
