How to Start a Career in Network and Cloud Security: CCNA to Firewall Mastery
Jul 10, 2025
Do you know that network and cloud security expertise fills up the position of second fastest-growing skill category across the world (according to the World Economic Forum's Future of Jobs Report 2025). This means that this industry is just a number behind AI and big data skills.
On top of that, the demand for cloud security skills has grown by 115% from 2020 to 2025. There are approximately 20,000 job openings for Cloud Security Engineers. All thanks to the rise in cybersecurity attacks and cloud adoption.
With such high demand, building a career in cloud network security is a no brainer. In this blog, we’ll cover the importance of networking basics, navigating through CCNA, CCNP, firewall, how to become a cloud network engineer and various career opportunities to explore.
What are Networking Basics?
Networking basics are the fundamental concepts and components that help computers and devices to communicate with each other across a network. Networking basics are the building blocks for connecting to the Internet, accessing files on a server or setting up a router at home.
The following are the main concepts in covering networking basics:
IP addressing
IP addresses are unique identifiers for devices present in a network. It is the address of your computer.
Subnetting
A large network is broken down into smaller fragments with the help of subnetting.
Routers and switches
Different networks are connected together with the help of routers. Switches are used to connect multiple devices within the same network.
MAC address
It refers to a physical address that is hardcoded into a device. It is used by switches to send data to the correct device.
Protocols
Protocols are a set of rules that decide how data is sent and received. For example, TCP/IP, DNS.
Ports
Ports can be considered virtual doors through which data enters and leaves a system. Some of the common ports include:
80 (HTTP)
443 (HTTPS)
22 (SSH)
Network topologies
Network topologies refer to the layout of a network. There are various topologies such as bus, star or mesh.
Firewalls
Firewalls refer to the security systems that filter both incoming and outgoing traffic.
NAT (Network Address Translation)
With NAT, multiple devices can share one public IP address on a LAN. Home routers work on NAT.
How to Become a Cloud Network Engineer?
With current demand for remote access and high security, Cloud Network Engineers are extremely in demand these days. If you want to become a Cloud Network Engineer, you can follow the roadmap as given below:
CCNA:
The first step to become a Network Security Engineer is to begin with Cisco Certified Network Associate (CCNA) certification. You cover networking basics in the CCNA course. These include routing, switching, IP addressing, etc.

2. CCNP:
Furthermore, in order to deepen your expertise in networking, Cisco Certified Network Professional (CCNP) certification helps you grasp the important concepts of network security. There are two main exam curricula that you need to learn to become job-ready. These are:
CCNP ENCOR
CCNP ENCOR is a core exam for CCNP Enterprise. The main focus of this certification includes network infrastructure, virtualization, network assurance, security and automation.
CCNP ENARSI
CCNP ENARSI is one of the specialization exams that covers advanced routing protocols such as OSPF, EIGRP, and BGP, infrastructure security, VPN technologies and automation.
Palo Alto Firewall
The most important skill to learn after learning CCNP ENCOR and ENARSI is learning the skills of firewalls. Palo Alto firewall is the world’s leading firewall. Most of the tech giants use this firewall, therefore, becoming skillful in it can help you land a high-paying job as a Network Security Engineer.
AWS Certified Solutions Architect - Associate
AWS Solutions Architect is an associate-level certification that is an ideal choice for aspiring Cloud Engineers who want to build a career in cloud computing. This certification validates your skills on design of cost and performance optimized solutions. Minimal to no coding experience is needed to take this exam.
AWS Certified Advanced Networking - Specialty:
This is a high-level certification you can do to specialize further in managing critical and complex networking. You deepen your knowledge in AWS security, storage, and networking services, plus expertise in advanced architectures including IP VPN, MPLS, automation tools, routing protocols, multi-region solutions. You also learn about network security features like DDoS protection.
This course truly equips your learning of networking basics and other concepts like CCNA, CCNP, Firewall.
AWS Certified Security - Specialty:
It is another specialty-level certification that helps you in validating your skills in securing AWS workloads and data. You learn to design, implement and manage security solutions within the AWS Cloud.
With all these certifications in place, you can become a successful Cloud Network Engineer/Cloud Network Security Engineer.
