What Are The Types Of Network Management?
Each network management subdiscipline includes a number of operational components. Here is a list of the various types of network management.
Fault Management, in many ways, is the most fundamental area of the ISO network management model because it addresses the ability to keep the entire infrastructure operational. Fault management employs a mix of technology and processes to detect, repair, and document errors that could disrupt network operations.
Simple Network Management Protocol (SNMP) services are frequently used to detect problems and notify the appropriate IT manager. These tools also report and record issues for IT managers to analyze for trends, which can provide valuable insights into longer-term issues that can be addressed to improve performance.
Configuration Management entails more than just the initial configuration of routers, switches, servers, and other network equipment. It also includes the ongoing tracking of any changes to the system’s configuration. Because configuration issues are a major cause of outages, organizations must have effective tools and best practices in place to address all aspects of configuration management.
Monitoring and recording any configuration changes involving network hardware and software is a critical component of this. Documenting, for example, when a new network interface is installed or an operating system is updated. Although network administrators can manually record these changes, this can be a time-consuming and inefficient use of resources. Many people prefer to employ configuration management software.
Accounting Management records all network utilization data. Accounting management will bill back or track departments or lines of business for usage primarily for bookkeeping purposes. Chargeback is irrelevant for smaller organizations that do not have multiple departments. All businesses and government agencies, however, must track utilization.
This data is critical for cost management. It is also critical to recognize trends that indicate inefficiencies caused by a configuration issue or another error. Documenting which units and users consume bandwidth is critical for larger enterprises to justify the network’s relevance to business operations. Because IT is often viewed as a cost center, this type of network management is critical, especially since IT is frequently overseen by the CFO.
Performance Management aims to ensure acceptable service levels in the network to support optimal business operations.Collecting statistics on network service quality on a regular and consistent basis is an important part of performance management. Network monitoring tools collect performance data on a variety of metrics, either through passive network traffic monitoring or synthetic tests, and feed it into performance monitoring software. Performance monitoring collects and analyzes data on link utilization, packet loss rates, and network response times, among other metrics.
This information can be fed into an SNMP management system, which sends out alerts to network administrators when service levels fall below or exceed acceptable limits. While alert fatigue can be a problem, with network managers overlooking important fault indicators on occasion, effective performance management necessitates consistent and accurate monitoring. By correlating network performance data from multiple sources and associating it with IT data from other aspects of the enterprise, such as application performance data, network management systems can help reduce alert fatigue.
Security Management is a multilayered discipline within network management that necessitates continuous data collection and analysis. Network authentication, authorization, and auditing are all functions that fall under the security management umbrella. Network firewall configuration and management, vulnerability management, intrusion detection systems, and unified threat management are all included in most security management services. These can be used by businesses to create and implement policies.
Personnel both inside and outside the IT organization have realized how critical security is to business operations in recent years. A security breach can result in the loss of data and, in the worst-case scenario, the network’s downtime. The main goal of network security management is to ensure that only authorized users and devices have access to network resources. Unauthorized users or devices that are found to be infected with malware or other malicious or harmful software are blocked. Security management software with a roles-based component can also determine whether users should have access to specific resources based on their job function.
