Below are some security tips to protect you and your computer from email viruses and scams:
Sometimes it is difficult to recognize if an email is coming from the genuine sender by looking at the "from address" or the message context. Try to ask for additional confirmation from the counterpart if there is any doubt.
Another better way is to use the digital signature technology. Namely,
people can digitally sign their outgoing emails such that recipients would
have confidence that the messages are actually coming from them. A digital
signature technology based on digital certificate (i.e. e-Cert) has been
introduced to the campus users for nearly a decade and now all members of
the University can use their e-Cert to digitally sign their outgoing messages.
By looking for the "Signed"
message (message with the verified
icon in HKUST WebMail or thesigned
icon in Microsoft Outlook), you can assure sender's identity easily.
Viruses are often sent via email attachments. Our email firewall scans
incoming email and blocks known viruses. However, new viruses may get through
before the up-to-date virus signatures are available (just like they get
through your workstation's anti-virus software when new virus signatures
are not yet available).
Besides, neither ITSC nor software vendors like Microsoft will send system patches as e-mail attachments. Instead, they will ask users to download the required software from their web sites. As a rule of thumb, do not open an attachment unless you are expecting it.
Don't Send Sensitive Personal or Financial Information in Email
When you send a message, you no longer have control over what is done with it or to whom it is forwarded. Do not send sensitive data in email as it is unsafe.
