Ages 13 to 18, first lesson free." canonical: https://learn.modernagecoders.com/cyber-security-course-for-teens-uk source: src/pages/cyber-security-course-for-teens-uk.html --- > A cyber security course for UK teenagers: defensive skills, legal practice and the Computer Misuse Act as the NCA explains it. Ages 13 to 18, first lesson free. In short The Computer Misuse Act 1990 makes it an offence to access computer material without permission, to impair a computer's operation, or to make or obtain tools for those purposes, and the National Crime Agency warns that teenagers often break it without realising: in an NCA survey of 10 to 16 year olds, 20% had engaged in behaviours that violate the Act. The NCA's Cyber Choices programme exists to steer that curiosity towards legal use. Employers need it: DSIT's 2025 research found 49% of UK businesses had a basic cyber security skills gap. Modern Age Coders teaches a defensive cyber security course for UK teenagers aged 13 to 18, live and online, covering how the internet works, passwords and hashing, phishing, malware concepts, encryption and web security, ending with instructor-built capture-the-flag puzzles. No coding is needed to start. Every exercise uses the student's own devices or puzzles built for the purpose. The first lesson is free, then USD 100 a month in a group or USD 150 one to one. Start here ## Three courses for a teenager interested in security The defensive security course itself, the programming that deeper security work needs, and how the web works underneath. Each card opens the syllabus.

Its page sets out the Act section by section, each with an example. | Section | Offence | The NCA's example | | --- | --- | --- | | 1 | Unauthorised access to computer material | Adam watches a friend type a password, then later logs in without permission and reads their messages | | 2 | Unauthorised access with intent to commit or facilitate further offences | Raj uses a teacher's unattended tablet to buy things with the saved card | | 3 | Unauthorised acts impairing, or reckless as to impairing, a computer's operation | Sarah uses a booter tool to knock a friend offline so she can win a game | | 3ZA | Unauthorised acts causing, or creating risk of, serious damage | Kim hacks a phone company and stops some people from calling the police, recklessly rather than deliberately | | 3A | Making, supplying or obtaining articles for use in offences under sections 1, 3 or 3ZA | Robin downloads software to break into a friend's laptop, even without having used it yet | ### Why teenagers in particular The NCA says "The average age of someone convicted for cyber crime offences is much younger than other crime types; offenders are often teenagers." In an earlier release, from January 2022, it reported referrals to its prevention team with "the median age at 15 and the youngest at nine". Its survey of 10 to 16 year olds found 20% engaging in behaviours that violate the Act, and 25% of those who game. Buying in-game items on someone else's account without permission, or DDoS-ing, are both offences, "despite often doing so unwittingly". ### The consequences the NCA lists Arrest and a possible criminal record, computers or phones taken away, risk of expulsion from school, and limits on internet use, careers and international travel. For the most serious offences, the Cyber Choices page states a maximum of "Up to life in prison for the most serious offences". None of this is meant to frighten a curious teenager away from the subject. The NCA's own point is the opposite: the skills are valuable, and there are legal places to use them. Sources, read 21 September 2026: [National Crime Agency, Cyber Choices](https://www.nationalcrimeagency.gov.uk/cyber-choices); [NCA, One in five children found to engage in illegal activity online](https://www.nationalcrimeagency.gov.uk/news/one-in-five-children-found-to-engage-in-illegal-activity-online); [NCA, Rise in school cyber crime attacks sparks NCA education drive](https://www.nationalcrimeagency.gov.uk/news/rise-in-school-cyber-crime-attacks-sparks-nca-education-drive), 17 January 2022. Section wording is as the NCA presents it; this page is not legal advice. The skills gap ## Half of UK businesses lack basic cyber skills From the Department for Science, Innovation and Technology's Cyber security skills in the UK labour market 2025, first published on 19 September 2025. | Finding | Published figure | | --- | --- | | Businesses with a basic cyber skills gap | 49% | | Charities with a basic skills gap | 59% | | Public sector organisations with a basic skills gap | 14% | | Businesses with gaps in advanced skills | 30% | | People in the UK cyber security workforce | About 143,000 | | Annual workforce gap | 3,800 people | | Cyber sector employers diversifying recruitment who hired through non-degree routes | 63% | ### What the basic gap means DSIT describes the basic gap as businesses "struggling with essential tasks including setting up firewalls, managing personal data securely and detecting malware". That is defensive work, and it is exactly where a beginner's course starts. The advanced gaps it names are forensic analysis, interpreting malicious code and penetration testing, which come much later and always under authorisation. ### More than one way in Of cyber sector employers who took steps to diversify recruitment, 63% said they had hired through non-degree routes and 41% had run events in schools or colleges. DSIT's annual inflow estimate also includes about 600 new apprenticeship starts flowing into the cyber labour market. For a teenager, that means a degree is one route among several; our page on [degree apprenticeships](/coding-before-a-degree-apprenticeship-uk) includes the level 6 standard with a cyber security option. Source, read 21 September 2026: [DSIT, Cyber security skills in the UK labour market 2025](https://www.gov.uk/government/publications/cyber-security-skills-in-the-uk-labour-market-2025/cyber-security-skills-in-the-uk-labour-market-2025). The workforce estimate covers the end of 2024. Practising legally ## Where a curious teenager can practise without breaking the law The rule is simple enough to put on a sticky note: only your own devices and accounts, only systems built for practice, and never anything without clear permission. | Legal practice | The offence it can turn into | | --- | --- | | Auditing your own accounts and passwords | Trying passwords on someone else's account | | Hardening your own home network settings, with your household's agreement | Scanning or testing a network you do not own | | Solving capture-the-flag puzzles built for the purpose | Attacking a real website to see if it works | | Studying how booter and DDoS attacks work in principle | Using a booter to knock anyone offline | | Reading about malware and how defences detect it | Downloading or sharing tools meant for attacking others | Our course syllabus puts the principle in one line, repeated as a checkpoint: "knowledge of weaknesses creates responsibility, never permission". Knowing how something could be broken never makes it acceptable to try it on a system that is not yours. Professional penetration testers work under written authorisation from the system's owner, and students learn to think the same way from the first week. ### UK routes worth knowing The NCA's [Cyber Choices](https://www.nationalcrimeagency.gov.uk/cyber-choices) site lists legal ways to develop skills and careers, from coding and web development to penetration testing, security operations and law enforcement. For girls, the NCSC's CyberFirst Girls competition is covered on our [CyberFirst Girls page](/cyberfirst-girls-competition-preparation). Code-breaking fans can look at the [National Cipher Challenge](/national-cipher-challenge-preparation). ### For parents The NCA encourages parents and teachers of 10 to 16 year olds to help them understand the severity of these offences and develop their skills in positive ways. A structured course is one way to do that. If a teenager has already crossed a line, the Cyber Choices programme is delivered through Regional Organised Crime Units and local police cyber teams. We are a teaching organisation, not part of that programme. The course ## Six months of defensive security Cybersecurity for Teens runs for 24 weeks over six months, for ages 13 to 18, with no coding required to start. | Month | Title | What it builds | | --- | --- | --- | | 1 | How the Internet Actually Works | Networks, addresses and what really happens when you load a page | | 2 | Passwords, Hashing, and Proving Who You Are | Why strong passwords work, how hashing protects them, and two-factor login | | 3 | Phishing and Social Engineering | How people, not machines, are usually the way in, and how to spot it | | 4 | Malware Concepts and Safe Habits | What malware does in principle and the habits that keep it out | | 5 | Encryption and How the Web Stays Trustworthy | Encryption, the HTTPS padlock, and web security ideas such as cookies and sessions | | 6 | The Capture-the-Flag Capstone | Instructor-built puzzles in cryptography, logic and file forensics, with written solutions | ### Defence first Every attack is studied so that the defence makes sense. Students harden their own accounts and audit their own digital footprint along the way. ### Puzzles, not targets The capture-the-flag month uses puzzle competitions built by the instructor: legal, safe, and a real test of thinking. ### Writing it up Solutions are written out, because explaining how a puzzle was solved is part of the skill, and a habit professionals rely on. Students who want to go further usually add programming next, since scripting underpins most technical security work. Python is the usual choice, then web development to understand the systems being defended. For school exams, security topics also appear in GCSE computer science, and our [AQA GCSE computer science](/aqa-gcse-computer-science-8525-help) page covers that specification. Stages ## Four stages for a teenager in security Placement depends on what a student already knows, not age. | Stage | What should be true | | --- | --- | | 1. Safe and aware | Your own accounts are secured and you can spot a phishing attempt | | 2. Understands the machinery | You can explain networks, hashing and encryption in your own words | | 3. Solves puzzles | You work through capture-the-flag challenges and write up your solutions | | 4. Builds and scripts | You write programs in Python and understand the web systems security protects | ### Stage three is where it clicks Puzzles turn knowledge into skill, legally. The wider sequence of subjects is on the [coding roadmap](/coding-roadmap). ### Stage four opens doors Programming is what turns an interest in security into a technical career path. It comes after the defensive foundations, not before. The catalogue ## Nine courses around cyber security Security first, then the programming and systems knowledge that deepen it.

Ritu Kedia Parent Questions from parents and teenagers ## What families ask about cyber security ### Is it legal for my teenager to learn hacking? Learning how attacks work is legal, and it is the basis of defence. Using that knowledge on devices, accounts or systems without permission is an offence under the Computer Misuse Act. Our course keeps every exercise on the student's own devices or puzzles built for practice. ### How common is illegal activity online among young people? In an NCA survey of children aged 10 to 16, 20% engaged in behaviours that violate the Computer Misuse Act, rising to 25% among those who game. The NCA says many do not realise it is a crime. ### What counts as an offence? The NCA's examples include logging into someone else's account without permission, using a booter tool to knock someone offline, buying things with someone else's saved card, and downloading software to break into another person's device. ### Does my teenager need to know how to code? No. Cybersecurity for Teens needs no coding to start. Python is a natural next step afterwards for students who want technical depth. ### Are there jobs in cyber security? DSIT's 2025 research found 49% of UK businesses had a basic cyber skills gap, and 63% of cyber sector employers diversifying recruitment had hired through non-degree routes. We teach skills; we do not promise jobs. ### What is capture-the-flag? A puzzle competition in which students find hidden answers, or flags, by solving challenges in areas such as cryptography, logic and file forensics. In our course the puzzles are built by the instructor for practice. ### What is Cyber Choices? A national programme co-ordinated by the National Crime Agency to help people use their cyber skills legally, delivered through regional and local police cyber teams. We are not part of it, but its website has useful resources. ### What ages is the course for? Ages 13 to 18. Younger children interested in technology usually start with coding courses instead. ### What does it cost? The first lesson is free. After that it is USD 100 a month in a group or USD 150 a month one to one, with no enrolment fee. ### When are lessons? After school on weekdays or at weekends in UK time, agreed in the first lesson. Teachers are four and a half hours ahead of the UK in summer and five and a half in winter.
