Software Tips

What is Network Administration?

Network administration encompasses the planning, setup, support, monitoring, and security of an IT network (LAN, WAN, WLAN, cloud connections) as well as all connected components such as routers, switches, firewalls, servers, end devices, and services. It ensures that the network is stable, high-performing, and secure, and that business processes run without disruption.

Building Blocks of Network Administration

Planning and design: Define the network topology, IP addressing, VLANs, subnets, routing policies, and security policies.
Setup and configuration: Install hardware (routers, switches, APs, firewalls), configure devices, and set up services such as DNS, DHCP, VPN, and Active Directory.
Monitoring and performance management: Monitor network traffic, bandwidth utilization, latency, and availability, and set up alerts and reporting.
Security and access control: Manage firewalls, VLANs, ACLs, VPNs, authentication, and role-based access permissions.
Maintenance and documentation: Maintain firmware updates, patches, backup strategies, configuration backups, and up-to-date network documentation (e.g. topology, IP plans).

Advantages of Network Management Software

The key advantage of modern network management software lies in its comprehensive transparency. It enables a consolidated view of the condition, performance, and anomalies across the entire network. Especially in hybrid IT environments, where data from different sources must be brought together, this central overview is crucial for rapid error detection and well-founded root cause analysis.

Continuous monitoring makes it possible to identify bottlenecks, connectivity issues, or unusual traffic patterns at an early stage. This reduces downtime and enables proactive measures before disruptions have business-critical impacts.

Another major advantage is the standardization of configuration changes. Features such as versioning, archiving, and rollback minimize the risk of faulty changes during live operations. At the same time, automation reduces manual effort and ensures consistent processes. According to IBM, closed-loop automation and automated workflows in particular help make operational processes more efficient and reduce dependency on individual specialists.

Network management software also offers clear benefits in the area of governance and compliance. According to the National Institute of Standards and Technology (NIST), such tools support policy enforcement, validate configurations, document assets, and enable continuous monitoring. This is particularly important for companies with high regulatory requirements and audit obligations.

Challenges in Network Administration

Network administration is increasingly facing the challenge of growing complexity. Companies today operate highly distributed infrastructures with multiple locations, heterogeneous system environments, and a mix of on-premises, hybrid, and multicloud environments. This fragmentation makes consistent management, monitoring, and protection of networks considerably more difficult.

At the same time, the pressure is increasing to balance performance, data traffic, and security. As the number of components across LAN, WAN, and cloud structures grows, so does the number of potential sources of error and dependencies. This leads to greater operational effort and increasing demands on scalability and stability.

Another critical factor is change management. Network adjustments often need to be implemented quickly, but they must not cause instability. Missing versioning, inadequate approval processes, or a lack of rollback mechanisms significantly increase the risk of misconfigurations and outages.

In addition, the analysis of operational data is becoming more demanding. Modern networks generate large volumes of logs, metrics, and events. Without suitable tools for correlation, prioritization, and automation, alert fatigue and inefficient manual analysis become a serious risk.

Typical Functions of Software for Network Administration

How Do I Choose Software for Network Administration?

A sensible selection process does not start with the feature list, but with your operational requirements: Which network areas need to be covered, which vendors and protocols are in use, what cloud and on-premises components exist, and which teams will work with the solution? Especially in hybrid and multicloud environments, Microsoft identifies the secure, consistent management of distributed systems and teams as a core challenge.

Criteria for evaluating software for network administration:

Environment coverage: LAN, WAN, WLAN, data center, branch offices, on-premises, hybrid, multicloud.
Discovery and inventory: automatic detection of devices, services, and topologies.
Monitoring depth: metrics, logs, traces, events, alerting, and dashboards.
Configuration management: backup, versioning, compliance checking, rollback.
Automation: workflows, APIs, integrations, and as little manual routine work as possible.
Security and compliance functions: policy checks, detection of unauthorized devices, traceability of changes.
Scalability and operating model: Does the solution scale with your infrastructure, including across multiple locations and clouds?
Usability and TCO: How high are the implementation effort, training requirements, and ongoing operational costs? These criteria are derived directly from the capabilities required today for visibility, configuration control, compliance, automation, and hybrid operations.

A short pilot phase is particularly valuable for the actual selection. Use real use cases to check whether the solution makes disruptions visible quickly, documents changes reliably, prioritizes alerts meaningfully, and can be integrated into your existing systems. In day-to-day operations, the quality of alerts, reports, and automation often matters more than the length of the feature list.

Selection of Questions to Ask Vendors of Network Administration Software and Further Tips

Detecting unauthorised traffic, network bottlenecks and much more.
Applications and ports can be configured.
Monitoring of data traffic at various times. The monitoring of networks, network components, application or service monitoring is important for identifying failures as early as possible in order to avoid potential business damage (loss of customers, damage to reputation, etc.) and service outages (service failure). To this end, the status of the various items listed above and their metrics are queried at regular intervals and stored in a database. This data is then usually displayed in the monitoring solution for the administrator in the form of graphs. Should any of the monitored metrics deviate from the target value and exceed a critical threshold, the administration team is informed, for example via SMS, pager or email, that action is required.
Ask about the requirements for high performance and security. Ask to see test results and certificates that provide sufficient evidence of both. Testing may also be required.
Customisable configuration options tailored to the existing infrastructure.
Don’t forget to consider options for load distribution.
Identifying the users with the highest bandwidth usage and the most frequently used applications. This allows you to keep track of potential vulnerabilities within your IT infrastructure.
Virtualisation options for streamlining or further automating administration.
Options for managing access rights and roles within the network to ensure compliance with data protection regulations.
Ask about options for simulations, statistics and ways to analyse logs.
Please check whether the software allows you to carry out a network component inventory for the systems it has detected, or whether it offers interfaces to other inventory management or office suites.
Check whether there is a licence management solution available to manage your existing network infrastructure and its licences. This includes licence management for software, operating systems and network components.
Ask about system reliability and all available contingency options.
IP scan options for checking IP addresses for spam behaviour, rejection, blacklisting, etc.
Does the software include a network sniffer? A network sniffer allows you to analyse and examine network data packets, for example to filter incoming and outgoing packets or prepare them for further processing. Network sniffers often also offer the option of checking the current network for Windows shares, for example.
The existing IT infrastructure must be taken into account.
Availability of plugins such as: J2 Web Transaction Monitor, MS Office SharePoint Monitor, AS400 Monitoring, SAP Monitor, Websphere MQ Monitor.
