Key rotation concepts in Azure - Step-by-Step Execution

Process Flow - Key rotation concepts

Start: Key in use

↓

Check rotation schedule

↓

Is rotation due?

No→Continue using current key

Yes↓

Generate new key

↓

Update services to use new key

↓

Retire old key

↓

End: New key active

This flow shows how a key is regularly checked and replaced with a new one to keep systems secure.

Execution Sample

Azure

1. Check if key rotation is due
2. If yes, generate new key
3. Update services to use new key
4. Retire old key

This simple process ensures keys are replaced regularly to maintain security.

Process Table

Step	Action	Condition	Result	Next Step
1	Check rotation schedule	Rotation due?	No	Continue using current key
2	Check rotation schedule	Rotation due?	Yes	Generate new key
3	Generate new key	N/A	New key created	Update services
4	Update services	N/A	Services use new key	Retire old key
5	Retire old key	N/A	Old key disabled	End process
6	End process	N/A	New key active and in use	Process complete

💡 Process ends when new key is active and old key is retired

Key Moments - 3 Insights

Why do we check if rotation is due before generating a new key?

To avoid unnecessary key changes and ensure keys are rotated only when scheduled, as shown in step 1 and 2 of the execution table.

What happens if services are not updated to use the new key?

Services will continue using the old key, which may be retired later causing failures. Step 4 ensures services switch to the new key.

Why do we retire the old key after updating services?

Retiring the old key after services switch prevents unauthorized use and maintains security, as shown in step 5.

Visual Quiz - 3 Questions

Look at the execution table, what is the result at step 3?

A Services updated to new key

B New key created

C Old key retired

D Rotation not due

💡 Hint

Check the 'Result' column in row for step 3 in execution_table

At which step does the system update services to use the new key?

A Step 2

B Step 3

C Step 4

D Step 5

💡 Hint

Look at the 'Action' column in execution_table to find when services switch keys

If rotation is not due, what does the system do according to the execution table?

A Continue using current key

B Generate new key immediately

C Retire old key

D Update services to new key

💡 Hint

See step 1 in execution_table where condition is 'No'

Concept Snapshot

Key rotation means regularly replacing keys to keep systems secure.
Check if rotation is due before creating a new key.
Generate new key and update services to use it.
Retire old key only after services switch.
This prevents service disruption and improves security.

Full Transcript

Key rotation is a process to keep security strong by changing keys regularly. First, the system checks if it is time to rotate the key. If not, it keeps using the current key. If yes, it creates a new key, updates all services to use this new key, and then retires the old key. This order ensures services do not break and security is maintained. The execution table shows each step clearly, and the variable tracker shows how keys and service settings change over time.
