Concepts
Anti-malware protection is critical in today’s digital landscape, especially for messaging systems like Microsoft 365. Configuring and managing anti-malware policies ensures that your organization’s data remains secure and protected from malicious threats. In this article, we will explore how to effectively configure and manage anti-malware policies for Microsoft 365 Messaging.
Configuring Anti-Malware Policies
To configure and manage anti-malware policies in Microsoft 365 Messaging, follow these steps:
- Sign in to the Microsoft 365 Security & Compliance Center using your admin credentials.
- Navigate to the Threat management section and select ‘Policy’ from the left-hand menu.
- Click on ‘Anti-malware’ to access the Anti-malware policies.
- By default, Microsoft 365 uses the ‘Default’ policy, which applies to the entire organization. You can modify this policy or create new ones based on your requirements.
- To create a new policy, click on the ‘Create’ button. Give your policy a meaningful name and provide a description, if required.
- Specify the malware detection settings. You can choose between ‘Standard’ and ‘Strict’ options. The ‘Standard’ option balances detection rates and the number of false positives, while the ‘Strict’ option increases detection sensitivity but may result in more false positives. Select the one that aligns best with your organizational needs.
- Configure the action to be taken when malware is detected. You can choose to ‘Block’ the malware, ‘Replace the attachment’ with a notification, ‘Quarantine’ the message, or ‘Notify the recipient’ without blocking the message.
- Customize the notification options. You can select whether to notify both the sender and the recipient, only the recipient, or not to send any notifications at all.
- Specify the action when malware is detected in SharePoint Online, OneDrive for Business, or Microsoft Teams. You can choose to ‘Allow’ or ‘Block’ access to files containing malware.
- Determine whether you want a report of all detected malware sent to the administrators. Enabling this option allows you to receive regular reports on malware activity within your organization.
- After configuring the desired settings, click on ‘Save’ to create the anti-malware policy.
Applying Anti-Malware Policies
Once the anti-malware policy is created, it can be applied to specific users, groups, or the entire organization. To apply the policy, navigate to the ‘Apply this policy to’ section in the policy settings and select the desired recipients.
Regular Review and Updates
It’s important to regularly review and update your anti-malware policies to ensure they remain effective against new and evolving threats. Microsoft 365 allows you to monitor and analyze the effectiveness of your policies through reporting and advanced threat protection capabilities.
In conclusion, configuring and managing anti-malware policies in Microsoft 365 Messaging is crucial to maintaining a secure and protected communication environment. By following the steps outlined in this article, you can customize anti-malware settings, define actions, and apply policies to safeguard your organization’s data and users from malicious threats.
