If you’re thinking about getting into tech or are already in it and considering your next step, network security training is one of the smartest moves you can make—and we have five powerful reasons to back that up.
But before we dive in, you might be wondering, What’s the difference between ‘network security’ and cybersecurity?
(Don’t worry. We hear this question all the time.)
Let’s define what “network security” refers to, specifically:
“Network security” is a subset of cybersecurity that protects company assets from breaches and attacks.
At Cisco, we define network security as protecting the underlying networking infrastructure from unauthorized access, misuse, or theft. Securing the network involves creating a secure infrastructure for devices, applications, and users to work securely.
Now, let’s look at our top five reasons why network security training should be your next move.
1. Cybersecurity threats are growing fast
The world is more connected than ever, and cybercriminals are taking advantage of that. Attacks have become more frequent and sophisticated, with hackers using artificial intelligence (AI) to automate attacks on networks.
Raj Chopra, SVP and Chief Product Officer for Security, warns that AI-powered cyber threats are increasing, making it more critical than ever to have trained professionals defending networks.
Every company that stores, processes, or transmits data relies on network security professionals to protect its systems. When we stop to consider the volume of businesses, hospitals, governments, and individuals relying on secure networks, it’s no question why the demand for skilled network security professionals is skyrocketing.
2. Companies need experts in privacy laws and compliance
Companies must follow the country’s regulations regarding how people use their products and data.
The European Union’s (EU) General Data Protection Regulation (GDPR) is the strongest privacy and security law in the world. It applies to EU data processed outside of the EU as well. State-specific regulations in the U.S. mean companies must carefully manage and protect user data. Tricky government or law enforcement requests for data are also common.
Businesses need security professionals who can help them:
- Ensure compliance with data privacy laws
- Build secure networks that protect user information
- Handle government requests for data responsibly
3. Remote work and cloud security are now business priorities
Remote work isn’t going anywhere. However, many employees connect from public Wi-Fi in coffee shops, hotels, and co-working spaces, or home networks that aren’t so secure.
Companies need to protect their data from:
- Unsecured remote connections
- Cloud service vulnerabilities
- Weak access controls
Organizations are investing heavily in Zero Trust security models, which require strict verification for every user and device. Learning how to implement these security measures makes you a valuable asset to employers.
4. The Internet of Things (IoT) expands attack surfaces
Yesterday, from inside my bedroom in a single-family home, my phone found 50 Bluetooth devices within range around my small neighborhood. Think about how many devices you have connected to the internet—smartphones, laptops, smartwatches, even smart refrigerators and security cameras.
Now multiply that by millions. Businesses, hospitals, and government agencies rely on IoT devices, which can also create security risks.
Since IoT security is still evolving, companies need experts to:
- Secure IoT networks
- Detect and respond to potential breaches
- Ensure that older and newer smart devices work safely together
By learning network security, you’ll be prepared to help secure everything from personal home devices to large-scale business operations.
5. Cybersecurity jobs pay well and have strong growth potential
One of the best reasons to consider network security training? The job opportunities and salaries.
- Information security analysts earn a median salary of $112,000 per year.*
- Job growth for information security analysts is projected at 32% through 2032, much faster than average.
With training in network security, you can pursue roles like:
- Network security engineer
- Cybersecurity analyst
- Security consultant
- Cloud security specialist
- Ethical hacker
Many companies struggle to fill these roles, translating into high job security and competitive salaries for skilled professionals. And you’ll be helping to keep the data of millions of people like you safe.
