Improve your Microsoft 365 email security with these three key settings:
Enabling these settings can significantly reduce spam, phishing, and email attacks for your organization.
To enable these features, you need to make DNS record changes as follows:
By taking these steps, you can enhance your organization's protection against malicious email activity.
Within Microsoft 365, there are three essential settings that can enhance your email protection. Implementing these measures is critical for defending against unwanted email threats. The first setting is the SPF, which stands for Sender Policy Framework.
SPF functions by authenticating the email sender against a DNS record. If the domain of the sender does not match the record, the email is treated as a potential threat. The second key setting is DKIM, which is a system for email verification.
DKIM ensures the authenticity of an email by attaching a digital stamp. This stamp confirms that the email was indeed sent from the claimed sender. The third setting is DMARC, which is a robust security protocol.
DMARC incorporates both SPF and DKIM checks. It mandates that emails from a domain are verified through these two methods. Emails failing to meet the criteria are typically discarded.
To activate these settings, specific steps must be taken. For SPF, a DNS record is added to your domain. The record will include specific information to ensure proper setup.
These actions are key to enhancing your email's protection in Microsoft 365. By implementing these settings, you reduce the risk of spam, phishing, or other email-based attacks targeting your organization.
The guidelines for enabling these protocols are straightforward. To set up SPF, you will need to include specific syntax in your DNS. For DKIM, a key pair creation is essential, which is then recorded in the DNS. DMARC also requires DNS record entry, with policy actions ranging from no action to rejection of violating emails.
Embracing these steps will significantly improve your organization's email integrity on the Microsoft 365 platform. While the configurations may seem technical, they play a crucial role in safeguarding communications against advanced email threats modern organizations face.
