What is Online Safety?
- Online safety (also called e-safety or cyber safety) means using the internet without being harmed by its misuse.
- The internet makes it easy to share and spread information, which can put private details at risk if you are not careful.
- Harm can come from uploaded media (like photos or videos) that may contain inappropriate content or be used in targeted attacks.
- Governments and organisations are especially concerned about the safety of children, teenagers, and elderly people online.
- Businesses also face cybercrime such as internet fraud, which can damage their finances, customer security, and trust.
The Three Cs: Content, Contact, and Conduct
- Content refers to what you see or read online – it can be inappropriate, offensive, or harmful.
- Contact means who you interact with online – some people may have bad intentions, like online predators or scammers.
- Conduct is how you behave online – you should be respectful and responsible, and avoid cyberbullying or other harmful actions.
- Being a good digital citizen means using technology safely, respectfully, and responsibly.
- You should be able to recognise inappropriate content, contact, and conduct, and know how to report your concerns.
Phishing
- Phishing is a scam where criminals pretend to be a trustworthy source (like a bank or a friend) to trick you into giving them private information.
- They often send fake emails or create fake websites that look identical to real ones, so you don't suspect anything.
- The goal is to steal passwords, credit card numbers, or other personal data.
- Never click on suspicious links or give out personal information in response to an unexpected email or message.
A phishing message uses urgency to make you click; the safe response is stop, check independently, report.

Malware and Spyware
- Malware is malicious software designed to harm your device or steal information.
- Spyware is a type of malware that secretly collects and sends your private information, like passwords, without your knowledge.
- Malware can be hidden in emails, software downloads, or files from unofficial sources.
- Types of malware include viruses, trojans, ransomware, worms, and rootkits.
- Malware is often hard to detect because it can be encrypted or disguised, so always use trusted sources and keep your security software updated.
The malware infection chain: delivery, execution, infection, impact, then persistence and spread.

Cyberstalking and Cyberbullying
- Cyberstalking is using the internet or electronic means to harass or stalk someone – it can include false accusations, threats, or gathering personal information to embarrass or harm.
- Cyberbullying is using online communication (like social media or messaging) to abuse, intimidate, or overpower someone.
- Cyberbullying is a serious problem: studies show that 23% of teens have been victims, and some victims experience suicidal thoughts.
- It can include posting hurtful comments, spreading rumours, or sharing embarrassing photos without permission.
- Child-on-child abuse online often falls under cyberbullying, but it can also involve physical or sexual harassment, relationship abuse, or grooming.
Obscene or Offensive Content
- Some websites contain offensive, explicit, or hateful content that can make users feel unsafe or uncomfortable.
- This content can appear as pop-up ads, unsuspecting links, or on social media.
- Hate speech targets marginalised groups and is often not taken seriously by moderation teams.
- Platforms try to balance moderation with free speech, but offensive content can still slip through.
- If you see offensive content, you should report it to the platform and talk to a trusted adult.
How to Stay Safe and Report Concerns
- Protect your personal information – never share passwords, addresses, or other private details online.
- Think before you post – once something is online, it can be hard to remove and may be shared widely.
- Use privacy settings on social media to control who can see your posts and contact you.
- Block and report users who make you feel uncomfortable or who are abusive.
- If you are worried about anything online, tell a trusted adult (like a parent or teacher) or use report buttons on websites and apps.
- In the UK, you can report concerns to CEOP (Child Exploitation and Online Protection) or the NSPCC.
Small habits: keep software updated, check the web address, use official sources, and pause before entering information.

Being a Good Digital Citizen
- Respect others online – treat people the way you would like to be treated.
- Don't spread rumours or share hurtful content about others.
- Check facts before sharing information to avoid spreading misinformation.
- Support friends who are being bullied online and encourage them to report it.
- Remember that your online actions have consequences – they can affect your reputation and others' wellbeing.
