The Need Of Network Management Software In A Large Corporate Organization Is A Need As Part Of The Information Security Management
To ensure that information is securely stored and transmitted within networks and that the supporting infrastructure is protected, Information within networks and passing over public networks must be kept secure and protected from unauthorized access. It is therefore, one of the tool to help the organization maintain, operate the network infrastructure is network management system. Network management is one of the elements of the information security management system.
Network management refers to the activities, methods, procedures, and tools that pertain to the operation, administration, maintenance, and provisioning of networked systems.
- Operation deals with keeping the network (and the services that the network provides) up and running smoothly. It includes monitoring the network to spot problems as soon as possible, ideally before users are affected.
- Administration deals with keeping track of resources in the network and how they are assigned. It includes all the “housekeeping” that is necessary to keep the network under control.
- Maintenance is concerned with performing repairs and upgrades – for example, when equipment must be replaced, when a router needs a patch for an operating system image, when a new switch is added to a network. Maintenance also involves corrective and preventive measures to make the managed network run “better”, such as adjusting device configuration parameters.
- Provisioning is concerned with configuring resources in the network to support a given service. For example, this might include setting up the network so that a new customer can receive voice service.
Network WAN Monitoring
Network monitoring tools such as StatScout provide real-time and historical network performance monitoring though the use of specific Network Management Service (NMS) features. Network monitoring allows information to be gathered about the current and historical state of the network. This includes bandwidth utilization of WAN links and measurement of network response times.
NetIQ’s End2End product suite allows specific network application response times to be measured across the network. This then can be used to emulate the user experience during time of poor network performance and determine the cause of slow performance (client, server or network). Network monitoring is critical in developing a network performance baseline, and acts as a historical reference for future service level analysis and capacity planning requirements.
BitDefender Corporate Security Management
Beside a network monitoring software, a complete solution to proactively secure and manage your corporate network is strongly recommended. BitDefender Corporate Security is a robust and easy to use business security and management solution which delivers superior proactive protection from viruses, spyware, rootkits, spam, phishing and other malware. Check the product more detail here.
BitDefender Corporate Security enhances business productivity and reduces management and malware-related costs by enabling the centralized administration, protection and control of workstations, as well as of the file, e-mail and Internet traffic inside companies’ networks.
The minimum requirement with regards to Network Monitoring is:
- Network monitoring via a light-weight SNMP based tool such as Statscout shall be used to determine current and future bandwidth usage requirements.
- Network monitoring is to be used for link analysis during times of poor network (WAN) performance. Statscout can be used to provide SNMP based uptime and bandwidth link analysis of routers anywhere within the Rio Tinto network via a web based graphical interface.
- Network application traffic response times should be measured against a known (off peak) baseline. NetIQ’s End2End product suite can be used to provide server based monitoring and network response time analysis as well as real-time alerting and trend based reporting.
A common way of characterizing network management functions is FCAPS – Fault, Configuration, Accounting, Performance and Security.
Functions that are performed as part of network management accordingly include controlling, planning, allocating, deploying, coordinating, and monitoring the resources of a network, network planning, frequency allocation, predetermined traffic routing to support load balancing, cryptographic key distribution authorization, configuration management, fault management, security management, performance management, bandwidth management, Route analytics and accounting management.
Data for network management is collected through several mechanisms, including agents installed on infrastructure, synthetic monitoring that simulates transactions, logs of activity, sniffers and real user monitoring. In the past network management mainly consisted of monitoring whether devices were up or down; today performance management has become a crucial part of the IT team’s role which brings about a host of challenges — especially for global organizations.
