Explanation:
Box 1: Safe attachments policy
The ATP Safe Attachments feature checks to see if email attachments are malicious, and then takes action to protect your organization.
Box 2: Safe attachments policy
When you set up ATP Safe Attachments policies in Office 365, you can choose from several options, such as Block, Replace, and Dynamic Delivery. The dynamic delivery option eliminates email delays by sending the body of an email message through with a placeholder for each email attachment. The placeholder remains until the attachment is scanned by ATP Safe Attachments in Office 365. Email recipients can read and respond to their email messages right away, knowing that their attachments are being analyzed.
Box 3: Safe Link policy
ATP Safe Links in email
At a high level, here’s how ATP Safe Links protection works for URLs in email (hosted in Office 365, not on-premises):
1. People receive email messages that contain URLs.
2. All email goes through Exchange Online Protection, where IP and envelope filters, signature-based malware protection, anti-spam and anti-malware filters are applied.
3. Email arrives in people’s inboxes.
4. A user signs in to Office 365, and goes to their email inbox.
5. The user opens an email message, and then clicks on a URL in the email message.
6. The ATP Safe Links feature immediately checks the URL before opening the website. The URL is identified as blocked, malicious, or safe.
