What are the three levels of escalation of threat or security incidents?  Describe them.

What will be an ideal response?

Level One (minor to moderate)-These incidents are the least severe and typically must be managed within one working day of their occurrence.
Level Two (major)-These incidents are moderately serious. They should be managed on the same day they occur-ideally, within four hours.
Level Three (catastrophic)-These incidents are the most serious; they must be handled immediately.
