[Verse 1]
When policies need mathematical proof
Cedar brings that formal truth
Lean proof assistant by its side
Every decision verified
No more guessing what code will do
Mathematical certainty shines through
AWS built it right from the start
Formal verification is the art
[Chorus]
Cedar's proven, Cedar's clean
Best control language we've seen
Permit forbid, when unless
Readable syntax, no more mess
Two strengths rising to the top
Formal proof that will not stop
Readability that flows so free
Cedar's built for you and me
[Verse 2]
Rego makes you scratch your head
Cedar speaks like English instead
Permit forbid maps the way
Allow deny every day
When and unless clauses read
Like conditions we actually need
Management controls make sense at last
Readable syntax holds you fast
[Chorus]
Cedar's proven, Cedar's clean
Best control language we've seen
Permit forbid, when unless
Readable syntax, no more mess
Two strengths rising to the top
Formal proof that will not stop
Readability that flows so free
Cedar's built for you and me
[Bridge]
From Lean proof assistant comes the power
Mathematical truth every hour
While syntax flows like spoken word
Best of both worlds, haven't you heard
[Verse 3]
Principal action resource context
ABAC model keeps us connected
Users with role X may access
Resources classified, no more stress
Condition Z must be met
Perfect compliance, place your bet
Attributes guide the policy way
Cedar makes it clear today
[Chorus]
Cedar's proven, Cedar's clean
Best control language we've seen
Permit forbid, when unless
Readable syntax, no more mess
Two strengths rising to the top
Formal proof that will not stop
Readability that flows so free
Cedar's built for you and me
[Outro]
Formal proof and syntax bright
Cedar gets management controls right
Two strengths together, standing tall
The best solution for us all
