Authentic environments

A real terminal, not a simulation

Students run actual Linux commands in authentic environments, from a
bare terminal up to a full GUI desktop on Ubuntu or Kali Linux for
challenges that call for graphical tools. They build command-line
fluency and troubleshooting instincts that carry into college and careers.

FAQ
Frequently Asked Questions

What is the CodeHS Cyber Range?

The CodeHS Cyber Range is an interactive lab environment where students build real cybersecurity skills through hands-on, CTF-style challenges. Instead of only reading about security, students run real Linux commands, solve security puzzles, and capture flags across topics mapped to AP Cybersecurity standards, all inside CodeHS.

What is a capture-the-flag (CTF) challenge?

A capture-the-flag (CTF) challenge is a gamified security exercise where you solve a realistic problem to uncover a hidden "flag," a secret string that proves you cracked it. In the CodeHS Cyber Range, each CTF challenge presents a security scenario students work through, earning points as they find flags and progress through increasingly complex puzzles.

Do students run real Linux commands in the Cyber Range?

Yes. In the CodeHS Cyber Range, students work in authentic Linux environments where they run real commands, navigate file systems, manage permissions, and write shell scripts. These aren't watered-down simulations. Depending on the challenge, they may use a terminal only or a full desktop environment, as described in the lab environments question below. Students use the same command-line skills that translate directly to real-world cybersecurity work.

What lab environments does the Cyber Range provide?

Challenges run in real Linux environments inside CodeHS, not simulations. Most labs use a Linux terminal for command-line work like permissions, scripting, and forensics. Some challenges add a Full GUI desktop in the browser for tools that need a graphical interface. Depending on the challenge, students may work in Ubuntu Linux or Kali Linux environments with the same authentic tooling used in industry and AP Cybersecurity coursework.

What cybersecurity topics does the Cyber Range cover?

The CodeHS Cyber Range covers six core areas: Linux Basics, Cryptography, Web Security, Network Security, Forensics, and Binaries. Through hands-on challenges, students practice everything from command-line fundamentals and encryption to analyzing network traffic, investigating digital evidence, and exploring reverse-engineering basics.

Does the Cyber Range align with AP Cybersecurity?

Yes. Cyber Range challenges are aligned with AP Cybersecurity curriculum standards, giving students practical, hands-on experience with the concepts they'll need for the AP exam and beyond. As students work through the labs, they build the applied skills that reinforce what the AP Cybersecurity course covers.

Do schools need special hardware or software to run the Cyber Range?

No. Cyber Range runs inside CodeHS, so there's no specialized cybersecurity software to install or virtual machines to maintain. Students reach the lab environments through their CodeHS account, and the challenges run in the provided environments, so schools can offer authentic, hands-on security practice without extra hardware or IT setup.

How does the Cyber Range keep students engaged?

The CodeHS Cyber Range keeps students engaged through gamified, CTF-style progression. Each challenge is a realistic security puzzle with a hidden flag to capture, and the difficulty ramps up as students advance. They earn points and build confidence with every flag they find, staying motivated through increasingly complex challenges.

How much does the Cyber Range cost and how do I get access?

Cyber Range is an add-on feature that enhances a CodeHS Pro subscription. It's separate from Pro itself. To get pricing and add it for your school or district, request a quote and our team will help you get started with hands-on cybersecurity education.
