FCAPS is a network management framework created by the International Organization for Standardization (ISO).

FCAPS categorizes the working objectives of network management into five levels. The five levels are: Fault-management (F), Configuration level (C), Accounting level (A), Performance level (P) and Security level (S).

Fault Management: At the fault management level, network problems are found and corrected. Potential future problems are identified and steps are taken to prevent them from occurring or recurring. With fault management, the network stays operational, and downtime is minimized.

Configuration Management: At the configuration management level, network operation is monitored and controlled. Hardware and programming changes, including the addition of new equipment and programs, modification of existing systems, and removal of obsolete systems and programs, are coordinated.

Accounting Management: The accounting management level, which might also be called the allocation level, is devoted to distributing resources optimally and fairly among network subscribers. This makes the most effective use of the systems available, minimizing the cost of operation.

Performance Management: The performance management level is involved with managing the overall performance of the network. Throughput is maximized, network bottlenecks are avoided, and potential problems are identified.

Security Management: At the security management level, the network is protected against hackers, unauthorized users, and physical or electronic sabotage. The confidentiality of user information is maintained where necessary or warranted.
