In this video, we’re tightening up network security and showing you how to secure Cisco devices using RADIUS-based AAA (Authentication, Authorization, and Accounting)!

Join us as we say goodbye to our rogue engineer account, BOB (sorry Bob 👋), and replace local logins with a centralised, secure RADIUS setup. We’ll walk through the full configuration — from setting up the AAA model to pointing your Cisco gear to a RADIUS server for proper user management and accountability.

✅ What you’ll learn: • Why local accounts are a security risk 🔓 • How to configure AAA on Cisco routers/switches 💻 • Integrating Cisco with a RADIUS server (FreeRADIUS) • Testing login and verifying access control 🧪 • Removing backdoor accounts like BOB 🕵️‍♂️

Whether you’re a network engineer brushing up on your AAA skills or locking down your infrastructure, this video will give you a practical, hands-on demo.

Whether you’re prepping for your certs or building your lab, this tutorial makes the fundamentals unforgettable. Subscribe for more bold networking visuals and rock-solid tech insights!
