Privacy, Spam, Cyber Ethics, Digital Etiquette and Responsible Social Media (ICSE Class 9)

Updated 18 October 2026 · Fact-checked

Protecting privacy means controlling who sees your personal data, using strong unique passwords with two-factor authentication, never sharing OTPs and keeping accounts private. Spam is unwanted bulk messages, often scams: do not open, click or reply, and mark, block and report them. Cyber ethics, online safety and digital etiquette guide honest and kind behaviour, and responsible social media use rests on education, guidance and open communication.

Understand Privacy, Spam, Cyber Ethics, Digital Etiquette and Responsible Social Media

Privacy and personal data. Personal data includes name, address, phone number, date of birth, photos, location, school, passwords and bank details. Privacy is at risk through oversharing, weak or reused passwords, phishing (messages that trick people into giving OTPs or passwords), unnecessary app permissions, public Wi-Fi and data breaches.

Safety measures for individuals.
1. Use long, different passwords and turn on two-factor authentication.
2. Never share OTPs, PINs or passwords with anyone, even someone claiming to be from a bank or school.
3. Keep social media accounts private and share location only with trusted people.
4. Give apps only the permissions they need.
5. Look for https and the padlock before entering details; avoid banking on public Wi-Fi.
6. Log out of shared computers and keep software and antivirus up to date.
As on the chapter page, cyber crimes in India can be reported on the national cyber crime portal or on helpline 1930. Organisations that collect data must keep it secure and use it only for the stated purpose.

Spam. Unwanted, unsolicited bulk messages sent by email, SMS, messaging apps or social media. It wastes time, hides important mail, may carry malware and is often used for phishing and lottery or job frauds.
Protection: use the spam filter; do not reply, forward or click links in suspicious messages; do not open unexpected attachments; keep your email address and phone number private; check the sender and look for warning signs such as urgency, prizes you never entered and spelling errors; block and report unknown senders.

Cyber ethics. Responsible and moral behaviour online: respect others' privacy and property (no hacking), credit others' work, do not spread false information, rumours or hate, and use school computers only for permitted purposes.

Online safety. Do not share personal details with online-only contacts, recognise scams, download apps only from official stores, and tell a trusted adult about anything that makes you uncomfortable, saving evidence.

Digital etiquette (netiquette). Be polite, avoid typing in all capitals (it reads as shouting), disagree respectfully, ask before posting or tagging others, check facts before forwarding and name sources.

Digital footprint. The trail of data you leave online (posts, comments, likes, searches). It can be permanent and may be seen later, so build a positive one.

Responsible social media use. The syllabus stresses education (understanding platforms, privacy settings and misinformation), guidance (age rules, screen-time limits, block, mute and report tools) and open communication (talking with parents and teachers, who should listen without blaming). In cyberbullying: do not reply in anger, save screenshots, block the person, report to the platform and a trusted adult or the school, and never forward hurtful content. Before posting ask: is it true, kind and necessary?
