[Verse 1]
In the digital realm where data flows free
Four pillars stand guard for you and me
Access control at the gateway door
Change management keeping order in store
Operations running smooth through the night
Program development getting it right
[Chorus]
A-C-O-P, the controls we need
Access, Change, Operations, Programs indeed
Guard the gate, validate the change
Keep it running, develop with range
A-C-O-P, foundation so strong
Supporting applications all along
[Verse 2]
Who gets in and what can they see
Authentication and authorization key
Passwords expire, permissions reviewed
Segregation of duties well pursued
Least privilege principle guides the way
Monitor access every single day
[Chorus]
A-C-O-P, the controls we need
Access, Change, Operations, Programs indeed
Guard the gate, validate the change
Keep it running, develop with range
A-C-O-P, foundation so strong
Supporting applications all along
[Verse 3]
Changes coming to the system core
Document, test, approve before
Development, testing, production lanes
Emergency changes break the chains
Version control tracks every edit
Configuration management gets the credit
[Bridge]
Operations keep the lights on bright
Backup, recovery, monitoring sight
Job scheduling, error handling too
Capacity planning sees us through
Program development builds it clean
Testing, documentation, quality scene
[Chorus]
A-C-O-P, the controls we need
Access, Change, Operations, Programs indeed
Guard the gate, validate the change
Keep it running, develop with range
A-C-O-P, foundation so strong
Supporting applications all along
[Outro]
When financial reporting needs to be true
General controls are working for you
A-C-O-P, remember the way
IT controls working every day
