You’re starting a career in computer networking. What technical skills do you need to succeed?

1 Networking Fundamentals

The first skill you need is a clear understanding of the basic concepts and principles of computer networking. This includes the OSI and TCP/IP models, the common network topologies and architectures, the types of network devices and cables, the protocols and standards, and the network addressing and subnetting schemes. You should also be familiar with the basic network services, such as DNS, DHCP, FTP, and HTTP, and how they work. Networking fundamentals provide the basis for all the other skills you will learn and apply in your career.

2 Network Troubleshooting

The second skill you need is the ability to diagnose and resolve network problems quickly and efficiently. This involves using various tools and techniques, such as ping, traceroute, ipconfig, nslookup, Wireshark, and Nmap, to identify the source and scope of network issues. You should also be able to follow a logical and systematic approach to troubleshooting, such as the OSI model or the TCP/IP model, and document your findings and solutions. Network troubleshooting is a critical skill that can save time, money, and reputation for your organization.

3 Network Security

The third skill you need is the knowledge and practice of network security. This means protecting your network from unauthorized access, attacks, and threats, as well as ensuring the confidentiality, integrity, and availability of your network data and resources. You should be able to implement and configure various network security measures, such as firewalls, VPNs, encryption, authentication, and access control. You should also be aware of the common network vulnerabilities and risks, such as malware, phishing, denial-of-service, and man-in-the-middle attacks, and how to prevent and mitigate them. Network security is a vital skill that can safeguard your network and your organization.

4 Network Automation

The fourth skill you need is the ability to automate network tasks and processes using scripts and tools. This can help you save time, reduce errors, improve consistency, and enhance scalability of your network operations. You should be able to write and run scripts using languages such as Python, PowerShell, or Bash, and use frameworks and libraries such as Ansible, Puppet, or Netmiko. You should also be able to use APIs and RESTful services to interact with network devices and applications. Network automation is a valuable skill that can boost your productivity and performance.

5 Network Design

The fifth skill you need is the competence and creativity to design network solutions that meet the needs and goals of your organization. This involves analyzing the network requirements, planning the network topology and architecture, selecting the appropriate network devices and technologies, and testing and validating the network functionality and performance. You should also be able to document and present your network design using diagrams and reports. Network design is a crucial skill that can optimize your network efficiency and effectiveness.

6 Network Communication

The sixth skill you need is the ability to communicate effectively with different stakeholders in your network environment. This includes your colleagues, managers, clients, vendors, and end users. You should be able to explain technical concepts and issues in simple and clear terms, listen and respond to feedback and queries, and collaborate and coordinate with others on network projects and tasks. You should also be able to write professional and concise network reports, proposals, and documentation. Network communication is an essential skill that can enhance your network relationships and reputation.
