According to the International Organization for Standardization (ISO), there five best practices and standards in the area of network administrator: fault management, configuration management, performance management, security management and accounting management.

The objectives fault management is to detect and automatically fix network problems and to extend notify users of problem in order to maintain the network functioning effectively. This is the most implemented of the ISO network management elements since the fault causes network degradation (Cisco, 2007). Under fault management, the following standard management platforms are effected: network discovery, topology mapping of network elements, even handler, performance data collector and grapher, and management data browsers.
The purpose of configuration management is to monitor system and network configuration so that software and hardware elements can be tracked and managed effectively. As a network administrator, it is important to accurately identify the location of the network device. The information must provide explicit description of how the resource are dispatched when the problem occurs (Cisco, 2007). As part of the configuration standards, each network devices must name beginning with the device name to the individual interface. The naming process should follow a well-defined standardized naming convention. This provide accurate information especially when troubleshooting network problems.
The performance management is normally controlled by Service Level Agreement (SLA) which is a written contract between the service provider and customers. The performance standard is that the network administrator must ensure that the metric values are measurable, meaningful and realistic to all parties (Cisco, 2007). The performance level keep on changing based on network device and traffic. As a network administrator, it is important to select network devices that support higher-layer protocol such as Apple Talk, Remote Source Route Bridging (RSRB) and Data Link Switching Workgroup (DLSW)
Control access to network resource is paramount since breaches on the network can lead to sabotage. Therefore, as a network administrator, it is important to implement security policies and procedures that are sound. This can be achieved by setting a minimum configuration standards for all switches and routers (Cisco, 2007). These include the use of authentication, authorization and accounting in order to protect the network from unauthorized persons
The purpose of accounting management is to determine network utilization parameters in order to regulate group of users or individuals appropriately. As a network administrator it is my responsibility to ensure that network resources are effectively utilized. Network resource utilization can be achieved through the use of Cisco IP and Cisco NetFlow accounting features (Cisco, 2007). It is also important to ensure that billing system and usage-based accounting methods are included in the service level agreement.
