When you complete your network administrator training, you’re stepping into a field that’s evolving fast and under constant threat. Cybersecurity is no longer a bonus skill for IT professionals; it’s a core responsibility. And for network administrators, protecting systems, users, and data is now just as crucial as setting up hardware or configuring servers.
Here’s a look at the most important network security practices every new administrator should know.
Always Start With Firmware and Software Updates
Outdated firmware and software are like unlocked doors. Many attacks exploit known vulnerabilities that vendors have already patched.
If your systems aren’t up to date, you’re leaving your network exposed. Schedule regular checks, set auto-updates where possible, and always verify update logs to make sure nothing is skipped.
Implement Least Privilege Access
User access is one of the most common attack vectors. Instead of granting broad privileges, use the principle of least privilege: give users only the access they need to do their jobs, nothing more.
This limits damage if a user’s credentials are ever compromised. You’ll also want to implement role-based access controls and ensure that access is revoked promptly when roles change or when users leave the organization or platform.
As emphasized in network administrator training, always implement role-based access controls
Monitor Network Traffic
It’s easy to assume that once a firewall is up and an antivirus is running, your network is safe. But today’s threats are sophisticated, and passive monitoring isn’t enough.
Use tools like intrusion detection systems (IDS) and intrusion prevention systems (IPS) to actively monitor and log network traffic. Get familiar with normal activity patterns so you can spot anomalies quickly.
Create Regular Backup Protocols
No security strategy is complete without a robust backup plan. Backups should be encrypted, stored off-site or in the cloud, and tested regularly for data integrity.
Whether the risk is hardware failure, ransomware, or accidental deletion, having reliable backups means you’re never at the mercy of a breach.
Secure Devices and Endpoints
With more devices connecting to your network, including remote laptops, phones, and IoT equipment, every endpoint becomes a risk. Per your network administrator training, make sure each one is protected with antivirus software, strong passwords, and up-to-date security patches. Implement device authentication and, if possible, require multi-factor authentication (MFA) for access.

Build Awareness Among Users
Even with the best technical setup, human error remains a major vulnerability. As a network administrator, part of your job is educating users about phishing emails, weak passwords, and safe browsing habits. Create short, regular training sessions or email tips to help keep security top of mind across the organization.
Reach that moment when your network runs smoothly, threats are proactively managed, and your team can count on you to keep them safe. That moment starts with what you learn in our network administrator courses and builds with every decision you make on the job.
The Foundation Starts with Network Administrator Training
Whether you’re fresh out of a network administrator diploma or expanding your cybersecurity knowledge, your training is what gives you the tools to succeed. It’s not just about knowing how to connect devices; it’s about protecting the integrity of every connection, every user, and every system you manage.
