What is a Network Administrator?

A network administrator optimizes a network infrastructure including hardware, software, and policies. The administrator watches out for attacks that may try to corrupt or change data within an entire system or on individual computers.

In essence, a network administrator is the caretaker of an organization’s networks — every device attached to the network, every application running on those devices, and everything being passed through the network falls under their purview.

These professionals ensure that the systems are secure from harmful attacks, that installed software works as expected, and that applications function properly with other apps on the same system.

A network administrator may also:

• Evaluate and improve the performance of a network or system
• Add computer users to a network, as well as grant and modify security permissions on the network
• Instruct people on how to use hardware and software
• Review and resolve any issues on the network

Network administration is a hands-on job that requires close attention to detail and creativity in solving problems.

How to become a network administrator

Cyberseek data shows that of the employed network admins, 10 percent hold at least an associate degree, 43 percent have a bachelor’s degree, and roughly 47 percent have advanced to a master’s degree.

The usual path to becoming a network administrator involves obtaining a Network Administrator Bachelor’s Degree. Another option is to obtain a computer science bachelor’s degree with a concentration in network administration or an information technology (IT) degree, which includes learning about high-level concepts in computer networking and how they work. Online IT degrees are also becoming more common.

Ideally, students earning an associate’s degree in information technology should take courses that cover topics like routing, switching, and security protocols, to give them a foundation in the same knowledge areas as the first two paths, but may be less technical than traditional bachelor’s degree programs.

Since administrators work with computer hardware and technology, a degree in computer engineering or electrical engineering is sufficient as well. Classes in networking, computer programming, and system design are frequently included in these programs. 

Having the right certifications can also help you catch the attention of hiring managers who prefer people already trained for this position such as:

• Cisco Certified Network Associate
• Cisco Certified Network Professional
• CompTIA Security+
• IAT Level II Certification
• Certified Information Systems Security Professional

In addition to education and certifications, students should create a resume that highlights their IT experience, including PCs and networking. Network administrators should also consider earning vendor-specific certifications. Professional networking can also help find jobs in this field.

What does a day in the life of a network administrator look like?

Working as a network administrator can be incredibly challenging. Network administrators may need to:

• Respond to network issues as they arise – troubleshooting, determining the root cause, and potential steps toward recovery (or patching as a temporary solution)
• Address user requests for assistance with hardware and software
• Create and manage business continuity plans in case of device failure or natural

A network administrator may be responsible for:

• Making sure the network and servers are secure and up to date with patches and upgrades
• Managing security software like firewalls and related systems
• Monitoring server logs for any anomalies or suspicious activity
• Checking email alerts triggered by security devices or system monitoring tools
• Installing, configuring, and maintaining electronic hardware such as routers, switches, firewalls, load balancers, and wireless access points (WAP)

Network administrator skills and experience

A career in network administration can lead anywhere from maintaining a single system to managing an entire organization’s IT needs. Some organizations may require their administrators to meet a general set of requirements:

• Technical skills: Network administrators need to have a strong foundation in networking fundamentals and technologies. This includes knowledge of TCP/IP, routing, switching, network security, network operating systems, and network hardware.
• Problem-solving and analytical skills: Network administrators need to be able to identify and resolve network problems quickly and efficiently. They should also be able to analyze network performance and identify areas for improvement.
• Communication and teamwork skills: Network administrators need to be able to communicate effectively with both technical and non-technical audiences. They should also be able to work well as part of a team.

In addition to these general skills and experience, network administrators may also need to have specific skills and experience depending on the industry or company they work for.

For example, network administrators who work in the healthcare industry may need to have experience with medical devices and healthcare networks. Network administrators who work for financial institutions may need to have experience with financial networks and security protocols.

Outlook for a network administrator

The U.S. Bureau of Labor Statistics (BLS) anticipates a 3 percent job decline for network and computer systems administrators from 2023 to 2033. As companies move to cloud technologies, the demand for skilled administrators rises.

The surge in cyber threats highlights the value of network security expertise, and with automation reshaping tasks, adaptability and staying updated are essential for administrators.

How much does a network administrator make?

According to Payscale, the salary range for network administrators is $47,000 to $92,000, with an average salary of $66,494.

ZipRecruiter, on the other hand, reports that the average annual salary for network administrators is $81,749, with a range of $33,500 to $124,000.
