Phishing emails try to trick users into sharing passwords, OTPs, bank details, or clicking malicious links.
Signs of phishing:
Spoofing means the attacker forges the sender address to look like a trusted person/company.
Attachments like .exe, unknown .zip, or macro-enabled files can contain malware.
MFA adds one more layer like OTP/app approval. Even if password is leaked, MFA reduces risk.
Backup means keeping an extra copy of important data so it can be restored after loss. Common backup options:
Rule: “Backup regularly and test restore.”
if sender_domain is not official_domain then flag "suspicious"
if email asks for OTP/password/PIN then flag "phishing"
if link domain != shown brand domain then flag "phishing"
if attachment type is executable or unknown then flag "malware risk"
if flagged then do not click; verify via official channel
Digital footprint is the data trail you leave online while using the internet.
Best practice: share minimum personal data and review privacy settings.

Cyber laws provide legal protection against online fraud, hacking, identity theft, and misuse of data. Users should:
Always verify the sender and the link domain. Banks and genuine companies never ask for OTP/PIN/password over email. When in doubt, open the official website manually instead of clicking the email link.
Your posts, comments and even browsing history can create a lasting record. Use privacy settings, think before posting, and avoid sharing sensitive personal information.
Professional emails should be clear, polite and structured. A good subject line, proper greeting, brief body and correct signature create a strong business impression.

From this topic
CC (Carbon Copy) is used to send a copy of email to additional recipients and all recipients can see the CC list, whereas BCC (Blind Carbon Copy) hides the BCC recipients from other recipients. CC is used when transparency is required for information sharing, whereas BCC is used when privacy is required or when sending mail to many recipients without showing addresses. In CC, recipients know who else received the mail, whereas in BCC, other recipients do not know the BCC recipients. (Any three differences can be written.)
Email etiquette means writing and using email in a professional, polite and effective manner. In business communication, good email etiquette creates a positive impression and reduces misunderstandings.
Firstly, a business email should have a clear and meaningful subject line so the receiver understands the purpose quickly, such as “Submission of project report” or “Request for quotation”.
Secondly, the email should begin with a proper greeting (Dear Sir/Madam or Dear Mr./Ms. Name) and the message should be written in a polite tone using words like please, kindly and thank you.
Thirdly, the content should be short, clear and well‑structured. Important points can be written in paragraphs or bullet points. Avoid slang, informal words, and avoid writing in ALL CAPS because it looks rude.
Fourthly, correct grammar and spelling are important. The sender should proofread before sending, because errors reduce professionalism.
Fifthly, if any file is attached, it should be attached properly and the attachment should be mentioned in the email body. Also, a professional signature with name, designation/class and contact details should be added at the end.
Finally, one should reply within reasonable time, maintain the email thread, and use CC/BCC properly. Therefore, following email etiquette helps in effective and respectful business communication.
