Protection Against Malicious Attachments
Email security services need to go beyond filtering and address end-user or human error to the maximum extent possible, according to Hannah O’Donnell, director of sales at Collabrance. Microsoft’s Advanced Spam Filter (ASF) settings detect and protect against malicious attachments and flag messages that might contain suspicious activity to verify the user wants to click on them, O’Donnell said.
This protection should extend beyond Exchange and other include other pieces of the Microsoft Suite such as Word and Teams to ensure that suspicious or abnormal activity is highlighted, according to O’Donnell. Meanwhile, O’Donnell said advanced spam filtering blocks suspicious messages from getting into a user’s inbox to help employees avoid clicking on something they shouldn’t click on.
Btely, O’Donnell said no email security service can prevent human error, so customers must be educated to check the sender’s email address and examine the email header and body for unusual spelling mistakes to ensure the sender is legitimate before clicking on links. Companies should also familiarize themselves with popular scams and implement security awareness training via automated campaigns.
