Network Administration

A network administrator, also known as a network admin, plays a critical role in managing and maintaining an organization’s computer network infrastructure.

Their day-to-day activities can vary depending on:

• the organization’s size,
• complexity, and
• specific network requirements.

However, here are some common tasks and responsibilities that network administrators typically perform. Note, that some of these activities, such as user support, network monitoring, and others will occur daily, or nearly every day. Other activities will occur routinely such as on a weekly, monthly, or even quarterly schedule; such as configuration, patching, etc. While some occur rarely, such as redesigning the network. This might be only done once every few years, if that often.

• User Support: They provide support to end-users who encounter network-related problems. This includes troubleshooting network connectivity issues, assisting with configuration, and resolving connectivity problems. This is why help desk is where most people start, because you’re always providing some sort of support to users.
• Network Design and Planning: Depending on the organization’s growth and evolving needs, they may be involved in network design and planning activities, such as expanding the network infrastructure, adding new network segments, and optimizing network performance.
• Network Configuration: Network administrators configure and maintain network devices such as routers, switches, firewalls, and access points. They ensure that these devices are properly configured to meet the organization’s requirements and security standards.
• Network Implementation: Physically setting up and configuring network devices. This can include running cables, to setting up networking closets.
• Network Monitoring: Network admins regularly monitor the organization’s network to ensure it is running smoothly and without disruptions. They use network monitoring tools to track network performance, identify issues, and take proactive measures to prevent downtime. Issues can arise because of heavy usage, changes in personal, special events, as well as network intrusion.
• Performance Optimization: They work to optimize network performance by identifying and resolving bottlenecks, optimizing traffic flows, and managing network resources effectively.
• Network Upgrades: Admins plan and execute network upgrades, which may involve replacing or adding network equipment and implementing new technologies to improve network performance or security.
• Security Management: Network security is a crucial aspect of the role. Admins implement and manage security measures, including firewalls, intrusion detection systems, and encryption to protect the network from external threats and unauthorized access. Interestingly, most breeches come from internal sources, which must be secured therefore as well.
• Patch Management: They keep network devices and software up to date by applying patches, updates, and security fixes to mitigate vulnerabilities and enhance network security. This is generally considered simpler compared to an application manager as they don’t have as many devices in types or numbers compared to the number of applications.
• Backup and Recovery: Admins implement and oversee backup and disaster recovery solutions to ensure data and network configuration can be restored in case of hardware failures or data loss. For example, what happens if your internet connection goes down to your building? Or what happens if an important piece of equipment fails?
• Vendor Relations: They communicate with network equipment vendors and service providers to obtain technical support, resolve issues, and manage vendor relationships.
• Documentation: Network administrators maintain detailed documentation of the network configuration, including network diagrams, IP address allocations, hardware inventory, and configuration settings. This documentation is essential for troubleshooting and future planning. Every position, if done well, has to do this.
