	'''Self-Stabilization''' refers to a system's ability to recover automatically from unexpected faults. '''[[Self-Protection]]''' is finally a property of systems which automatically defend themselves against malicious attacks or cascading failures. It uses early warning to anticipate and prevent systemwide failures. Other useful self-properties are related to analysis and diagnosis: '''Self-Describing''' and '''Self-Explaining''' systems are useful if we want to understand distributed systems which are getting more and more complex. They are also necessary for intelligent autonomous systems with the abilities of self-healing. Less intelligent systems must rely on restart of affected components, which is the foundation of the [[Recovery-Oriented Computing]] (ROC). All these properties are desirable, because the deploying, operating and maintaining of complex systems can be very costly, difficult and expensive.

'''[[Self-Protection]]''' is finally a property of systems which automatically defend themselves against malicious attacks or cascading failures. It uses early warning to anticipate and prevent systemwide failures. Other useful self-properties are related to analysis and diagnosis: '''Self-Describing''' and '''Self-Explaining''' systems are useful if we want to understand distributed systems which are getting more and more complex. They are also necessary for intelligent autonomous systems with the abilities of self-healing. Less intelligent systems must rely on restart of affected components, which is the foundation of the [[Recovery-Oriented Computing]] (ROC). All these properties are desirable, because the deploying, operating and maintaining of complex systems can be very costly, difficult and expensive. Modern [[Distributed System\|distributed systems]] are inherently complex.
