Gartner characterizes IT resilience as being reliable, tolerable and recoverable:

  • Reliable: The degree to which your systems can remain performant, secure, and meet service-level objectives (SLOs) amid known and unknown IT hazards
  • Tolerable: The degree to which overt adverse consequences of IT hazards can be managed within levels that are tolerated
  • Recoverable: The degree to which systems and data can be confidently restored given the organization’s stated risk appetite for known and unknown IT hazards
