Detailed explanation-1: -To explain four dimensions of dependability-availability, reliability, safety and security. To explain that, to achieve dependability, you need to avoid mistakes, detect and remove errors and limit damage caused by failure.
Detailed explanation-2: -We will try to be more precise about four particular kinds of dependability properties: Correctness, reliability, robustness, and safety.
Detailed explanation-3: -There are five key facets to dependability: Security, which is the ability of a system to protect against attacks. Availability, which is a quantitative probability measure that a system can be accessible at a given point in time. Reliability, which is the probability that a system will work without failure over time.
Detailed explanation-4: -The dependability of a computer system is a system property that reflects the user’s degree of trust in the system. The most important dimensions of dependability are availability, reliability, safety, security and resilience.
