[Verse 1] When we start to build our fortress walls First we map what's in and what falls Outside our protection zone today Drawing lines where security stays Some components we inherit clean From the platform's trusted machine But we own what we deploy inside That's where our controls must reside [Chorus] Draw the line, what's in what's out That's what boundaries are about ISAs for the world outside Keep the connections verified Minimize but don't create gaps That's how security maps Authorization boundary clear Defines what we control in here [Verse 2] Interconnection agreements seal External systems that are real Document the handshake we make Trust but verify for safety's sake Every connection needs its rules Written down with proper tools Who controls what, where data flows That's what every admin knows [Chorus] Draw the line, what's in what's out That's what boundaries are about ISAs for the world outside Keep the connections verified Minimize but don't create gaps That's how security maps Authorization boundary clear Defines what we control in here [Bridge] Active-active makes it complex now Both clusters in the boundary somehow Replication links between the two Management plane comes through there too All three pieces must be assessed As one system when we test Don't split them up or you'll regret Missing pieces in your net [Verse 3] Make it smaller, save some time Less assessment by design But be careful not to split Connected parts don't benefit From artificial separation That creates gaps in protection Keep it whole but keep it tight Boundary drawn just right [Chorus] Draw the line, what's in what's out That's what boundaries are about ISAs for the world outside Keep the connections verified Minimize but don't create gaps That's how security maps Authorization boundary clear Defines what we control in here [Outro] What you own, what you inherit What connects through proper merit Draw it once and draw it right Keep your boundaries in sight
