Important tips on IT security
Identifying spam emails
You can identify spam emails by carefully checking the following points:
- Is the sender unknown to you?
- Is the style unusual?
- Is the attachment unexpected?
- Are the links incorrect/unexpected?
If you answer ‘yes’ to more of these points, the more probably it is that the email is malicious. When checking the email address, make sure you check not only the name given but also the address details.
