Safe and Responsible Online Behaviour

What this domain covers

This domain tests judgement: how you act online and how you protect yourself and others.

Digital footprint: everything you post, share, or that others post about you can persist. Assume public posts are permanent and searchable. Review privacy settings and limit what you share about location, routines, and identity.

Social media hygiene: verify connection requests, avoid oversharing personal details, and be cautious with third-party apps that request account access.

Safe browsing: check URLs carefully for lookalike domains, prefer typing addresses or using bookmarks, and avoid downloading software from unofficial sources. On public Wi-Fi, avoid sensitive transactions or use a trusted VPN.

Responsible conduct: do not share others' personal data without consent, respect copyright and licensing, and report cyberbullying or harmful content. Know your organisation's acceptable use policy and report suspected incidents promptly - early reporting limits damage.

Netiquette and law: treat others respectfully, avoid spreading unverified claims, and understand that online actions carry real-world legal and professional consequences.

Traps in questions

  • Assuming deleting a post removes all copies - screenshots and caches persist.
  • Believing a private profile makes all sharing safe; friends can reshare.
  • Treating public Wi-Fi as private; traffic may be intercepted.
  • Thinking incident reporting can wait until you are certain - report suspicions early.

Worked example

A stranger messages you asking to "confirm your account details" to unlock a prize. The safe response: do not reply or share anything; report and block the account, and verify through the official service directly.
