In this era of AI, cybersecurity threats are growing rapidly. According to the latest cybersecurity research, a new generation of artificial intelligence vulnerabilities may have a significant impact on the software we use every day.¹ As educators in Hong Kong, we have a responsibility to teach students how to protect themselves online through well-structured cybersecurity lesson plans, helping them develop good digital habits. This guide aims to provide Hong Kong secondary schools with a practical set of cybersecurity teaching materials, helping students understand and practise the principles of digital citizenship.
Cybersecurity is not just an issue for adults. As more and more Hong Kong secondary school students use the internet for learning, socialising, and entertainment, the online threats they face continue to grow.² A lack of awareness around personal data protection makes students more vulnerable to attacks.
Hackers may target students in the following ways:
For these reasons, systematically incorporating anti-scam education and cybersecurity knowledge into Hong Kong secondary school curricula has become an important direction in both local and international education policy.³
With the advancement of new AI technologies, researchers are now able to identify high-risk vulnerabilities in mainstream operating systems and browsers more efficiently than ever before. This has made it necessary for software vendors to continuously release security updates to patch these gaps.
Cybersecurity experts point out that when users delay installing updates, hackers can analyse the patch content, identify where the vulnerability lies, and then launch targeted attacks against systems that have not yet been updated. Therefore, installing software updates promptly is one of the most effective ways to reduce the risk of being compromised. From a personal protection standpoint, software updates sometimes include new features or interface changes — but what truly matters is that they patch known weaknesses, reducing the risk of devices being infiltrated by malware or taken over by unauthorised parties. This makes updating one of the most fundamental, yet often overlooked, steps in good cyber hygiene.⁴
Explain the danger of delaying updates: Hackers analyse software update content and use reverse engineering to identify vulnerabilities, then attack devices that have not yet been updated. The sooner you update, the lower the risk of being hacked.
Set up automatic updates:
Practical recommendations:
Several international public bodies and cybersecurity organisations have noted that all devices and software have a limited support period. Once a product passes its "End-of-Life" (EoL) date, the vendor will no longer provide security updates or patches.⁵ The UK's National Cyber Security Centre (NCSC) emphasises that obsolete products no longer receive patches, meaning known vulnerabilities remain exploitable indefinitely. Ideally, these outdated products should stop being used altogether.⁶
Teach students how to use https://endoflife.date/ to check the support period of common devices (such as phones, tablets, or operating system versions).
(For example: The iPhone XR's support period ended in April 2026, after which no further security support is provided.⁷)
Practical recommendations:
International research consistently shows that a large number of account breaches are directly linked to weak passwords, password reuse, and credential leaks. Hackers frequently use automated tools to attempt logging in across multiple platforms using the same set of credentials — a technique known as "credential stuffing."⁸ For Hong Kong secondary school students, developing good password security awareness is a fundamental requirement of digital citizenship education.
Encourage students to use a password manager (such as Roboform, NordPass, Google Password Manager, or the Passkey feature built into their device).
Practical recommendations:
Multi-Factor Authentication (MFA) is a security mechanism that requires users to complete an additional identity verification step when logging in — beyond just entering a password. For example, entering a verification code sent to your phone. This ensures that even if a hacker obtains a user's password, they still cannot successfully log in. Common forms of MFA include one-time passcodes (OTPs), hardware security keys, and biometrics (such as fingerprint or facial recognition). Hardware security keys and Passkeys are considered the most effective methods for resisting phishing attacks.⁹
Practical recommendations:
Passkeys are a new and more secure way to log in compared to traditional passwords. When a user registers, the Passkey is linked to the legitimate website and stored on the device or in a password manager. The system will then automatically verify whether the website's identity matches — if a phishing website is encountered, since the domain does not match, the Passkey simply cannot be used. This means users cannot be deceived by a fake login page.
Practical recommendations:
A phishing attack is when hackers use fake emails, text messages, or websites to trick users into revealing personal information or clicking on malicious links.¹⁰ Teaching students to recognise these tactics is the core of anti-scam education. For Hong Kong secondary school students, developing the skill to identify phishing attacks is the first step in protecting personal data.
Signs of a phishing email:
Practical recommendations:
Malware can infect devices through various means, including downloading pirated software, free game mods, or files from unknown websites.¹¹
Principles for Safe Downloads:
Practical recommendations:
The Hong Kong government has noted in LegCo documents that local cases have been recorded in which scammers used deepfake technology to create highly realistic synthetic video and voice content, impersonating company executives to instruct employees to transfer approximately HK$200 million. This reflects growing public concern about criminals using AI-generated faces and voices to commit fraud.¹² In Hong Kong secondary school anti-scam education, deepfake attacks are an increasingly important topic that can no longer be ignored.
Signs of a Deepfake:
Practical recommendations:
It is recommended that family members collectively establish a secret code word or safe phrase. If someone calls claiming to be a family member but cannot say the code word, it may be a scam call.
Choosing a Code Word:
Practical recommendations:
Developing a comprehensive cybersecurity teaching plan is an important foundation for promoting digital citizenship education in Hong Kong secondary schools. Teachers can make good use of ready-made cybersecurity online self-study courses and local teaching resources to systematically integrate relevant content into the curriculum.
Integrating into the Curriculum
Cybersecurity Teaching Activities
Home–School Partnership
Cybersecurity is not a one-time task — it is a way of life. Through systematic cybersecurity lesson plans and teaching programmes, we can help Hong Kong secondary school students build safe digital lives:
By following these steps, students can protect themselves in the digital world and become responsible digital citizens.
Password Managers (as recommended by Consumer Council testing)¹³: Roboform, NordPass, Google Password Manager
Antivirus Software (as recommended by Consumer Council testing)¹⁴: Avira Internet Security, Norton360, McAfee
Authenticator Apps: Google Authenticator, Microsoft Authenticator
In this digital age, cybersecurity education is the key to cultivating Hong Kong secondary school students who can use technology responsibly. Through well-developed cybersecurity lesson plans and digital citizenship education, we can help students grow and learn safely in the virtual world. It is our hope that this guide will assist educators and parents in more effectively promoting cybersecurity education in Hong Kong secondary schools, building a safer digital environment for the next generation.
