1. If I enter a value of 7 days and the policy is created in blocking mode, this means that if during first 7 days traffic violates a signature, it isn't blocked even if the policy is in blocking mode?
Yes that's true - it will not block but will log a learning suggestion so when the 7 days are over you can enforce all those signatures that have not been triggered and decide what to do (disable them on a parameter for example), if they have been.
2. If I enter a value of 0 days, this means that the signature immediately pass blocking or which remain in staging? From what I see on my ASM seems that the setting of 0 days with policy in blocking means that signatures are always in staging? Can this be?
I'm not sure about this but if 0 is allowed then I would've guessed they would not enter the staging period, so if the action was to block when a signature is triggered then it would block.
Application Security ›› Attack Signatures : Attack Signatures Configuration - here is where you can disable Staging for a Security Policy
3. But if we set a value of 7 days, we should always go (at the end of 7 days) on tab "Bluilding Policy > Manual> Staging-Thigtening Summary" and click on "Ready to enforce" for signatures? Or they pass automatically in "enforce ready"?
They won't automatically be enforced.
Hope this is useful,
