Live online, first class free." canonical: https://learn.modernagecoders.com/cyber-security-course-for-teens-australia source: src/pages/cyber-security-course-for-teens-australia.html --- > Defensive cyber security for Australian teens aged 13 to 18: protect accounts, spot phishing and lookalike domains, practise legally. Live online, first class free. In short A cyber security course for teens teaches young people aged 13 to 18 to protect accounts, recognise phishing and lookalike web addresses, understand how systems secure data, and practise only on systems they own or are permitted to test. The Australian Curriculum asks Year 7 and 8 students to identify phishing and explain multi-factor authentication. Modern Age Coders teaches the defensive side live online, in small groups or one to one, and the first class is free. Start here ## Three courses for a teen interested in security All three are for under-18s. Each card opens the syllabus.

That is both unlawful without permission and the wrong place to start. Learning how attacks work is part of defence, and it is taught by explaining them and by testing a student's own code. ### Why defence is the right start Every security professional spends most of their time preventing problems, not causing them. Defensive skills are useful from the first lesson, to the student and to their family. They also build the careful, permission-first habits the field depends on. A worked example ## 72 fake addresses and three ways to catch them A phishing message only works if the link looks right. Students measure which simple checks actually catch lookalike web addresses. We took 10 real Australian government web addresses, such as `ato.gov.au` and `my.gov.au`, and wrote a script that produces lookalike spellings of them: letters swapped for identical-looking letters from another alphabet, 0 for o, an extra word, a different ending, and the real name placed at the front of someone else's domain. That gave **72 lookalikes**. None of them was registered or visited; they exist only inside the script. | Check | Lookalikes flagged | What it misses | | --- | --- | --- | | Is it exactly on my list of real addresses? | 72 of 72 | Nothing in this test | | Is it at least 85% similar to a real address? | 43 of 72 | All 10 subdomain tricks and 10 wrong-ending fakes, 8 extra-word fakes, 1 swap | | Does it turn into an xn-- address when encoded? | 29 of 29 homoglyph fakes | Only applies to other-alphabet letters | ### The plain rule wins The simplest check, comparing the exact address with a short list of sites you actually use, caught every fake. The cleverer similarity score missed 29. ### Why similarity fails An address like ato.gov.au.secure-check.example contains the real name but belongs to whoever owns secure-check.example. It scores low on similarity, so a similarity check waves it through. ### The hidden letters A Cyrillic a looks exactly like a Latin a. Encoded for the internet, the fake becomes xn--to-6kc.gov.au, which gives it away at once. ### The curriculum link Australian Curriculum content description AC9TDI8P13 asks students to "explain how multi-factor authentication protects an account when the password is compromised and identify phishing and other cyber security threats". One of its elaborations describes phishing that uses "an email address from an unofficial domain", which is exactly what this exercise trains students to spot. ### What students take away Bookmarks and typed addresses beat links in messages. Reading a domain from the right-hand end tells you who owns it. And a smart-looking check is not automatically a good one: measure it before trusting it.

The script and its counts are our own; no lookalike address was registered or visited. The law ## Permission is the line Australian law treats access to a computer without authority as an offence. Students learn where the line is before they learn anything else. ### What the Criminal Code covers The Commonwealth Criminal Code, set out in the Schedule to the Criminal Code Act 1995, has a Part 10.7 headed Computer offences. Its sections include 476.2, "Meaning of unauthorised access, modification or impairment", and 478.1, "Unauthorised access to, or modification of, restricted data". States and territories have their own computer offence laws as well. We teach the principle, not legal advice. ### How that shapes the course Every practical task is on the student's own code, on flawed code samples written for teaching, or in organised challenges whose rules give permission. If a student is unsure whether something is allowed, the answer is to stop and ask. | We do | We do not | | --- | --- | | Explain how attacks work so they can be prevented | Teach or run attacks on real services | | Test students' own projects for weaknesses | Scan, probe or log in to systems without written permission | | Review flawed code samples written for teaching | Share tools for getting around protections | | Prepare students for organised, rule-bound challenges | Help anyone access someone else's account | Source, read 14 October 2026: Federal Register of Legislation, [Criminal Code Act 1995](https://www.legislation.gov.au/C2004A04868/latest/text), compilation C2026C00243, Part 10.7 table of contents. Legal practice ## Capture the flag, the legal way Capture the flag (CTF) challenges are puzzles in which every target is built to be solved and permission is given in the rules. They are where teens practise safely. | Practice | Why it is allowed | Skill it builds | | --- | --- | --- | | Securing their own website | They own it | Finding and fixing weaknesses in their own code | | Teaching code samples with planted mistakes | The code is ours and is read and fixed, not used against anything | Spotting and correcting unsafe code | | Organised student CTF events | Entry rules grant permission for the challenge targets only | Puzzles in encoding, cryptography and careful reading | | Threat model for a school club app | It is a paper exercise on their own design | Thinking like a defender | ### Year 9 and 10 students go further Content description AC9TDI10P13 asks students to "develop cyber security threat models, and explore a software, user or software supply chain vulnerability". Its elaboration places the hands-on part "in their own software", the same rule our course follows. ### Where it can lead ANZSCO groups security work with database and systems administration in minor group 262, whose definition includes maintaining "security policies and procedures". We make no promise about careers. The course builds understanding and safe habits that are valuable whatever a teen goes on to do. At home ## A family security check students run One of the first practical tasks is to help the household, with permission, tighten its own accounts and devices. | Step | What the student does | Why it helps | | --- | --- | --- | | Accounts list | With a parent, list the important accounts: email, banking, school, games | You cannot protect what you have not listed | | Sign-in strength | Help switch reused passwords to long passphrases in a password manager | One leaked password no longer opens everything | | Second step at sign-in | Turn on multi-factor sign-in where it is offered | A stolen password alone is not enough | | Updates | Check devices and apps are set to update automatically | Known holes are closed quickly | | Saved links | Bookmark the real addresses of the most important sites | The allow-list from the worked example, in practice | ### Permission and privacy Students never handle anyone else's passwords; the account owner types them. The task is to explain and help, not to take over. This mirrors the professional rule: security work happens with the owner's agreement. ### Why it is a good first task It is concrete, it can be finished in one sitting, and it helps someone straight away. It also shows the student that security is about people as much as code. Progress ## Four levels of defensive skill Students move on when they can demonstrate a level on their own work. | Level | What you can do | | --- | --- | | 1. Careful user | Secure your own accounts and devices and explain each step | | 2. Spotter | Recognise phishing, lookalike addresses and suspicious requests | | 3. Builder | Write code that handles input safely and stores data properly | | 4. Defender | Threat-model a small system and test your own code for weaknesses | ### Does a teen need to code first? Not for the first course, which needs no coding. Python helps from level three onwards. Many students take Python for Teens alongside it. ### Is this for a teen who wants to hack? It is for a teen curious about how security works. We channel that curiosity into defence and legal practice, and we are clear with students about the law. Curiosity plus permission is how the field is actually learnt. The catalogue ## Courses for security-minded teens All for under-18s. The free class decides where a student starts.

Ritu Kedia Parent Teens and parents ask ## Questions about cyber security courses for teens ### What does a cyber security course for teens cover? Protecting accounts, recognising phishing and lookalike web addresses, how systems secure data, threat modelling, and safe, legal practice on the student's own projects. ### Does the course teach hacking? It teaches how attacks work so they can be prevented. It does not teach attacking real systems, and all hands-on work is on systems the student owns or is permitted to test. ### What is a lookalike domain? A web address made to resemble a real one, using a swapped or foreign-alphabet letter, an extra word or a different ending. In our test an exact allow-list caught all 72 fakes; a similarity score caught 43. ### Is cyber security in the Australian Curriculum? Yes. AC9TDI8P13 covers multi-factor authentication and phishing in Years 7 and 8, and AC9TDI10P13 covers threat models and vulnerabilities in Years 9 and 10. ### Is it legal for teens to practise security skills? On their own systems and in organised challenges whose rules give permission, yes. Accessing computers without authority is an offence; the Commonwealth Criminal Code covers it in Part 10.7. ### What is a capture the flag event? A security puzzle competition where every target is built for the event and the rules grant permission to solve it. It is the legal way to practise. ### Does my teen need to code? Not for the first course. Python helps later, when students secure their own code. ### What age is it for? Teenagers aged 13 to 18. Adults have separate courses. ### Will this lead to a security career? We make no career or salary promises. The course builds understanding and safe habits that help whatever a teen chooses next. ### How much does the cyber security course cost? The opening class is free and asks for no card. Group and private monthly fees appear in the fees panel.
