FCAPS categorizes the working objectives of network management into five levels. The five levels are fault-management (F), the configuration level (C), the accounting level (A), the performance level (P), and the security level (S).
FCAPS is the ISO Telecommunications Management Network model and framework or network management. FCAPS is an acronym for fault, configuration, accounting, performance, security.
In the 1990s the ITU-T, as part of their work on Telecommunications Management
Network (TMN), further refined the FCAPS as part of the TMN recommendation on
Management Functions (M.3400).
