Plan threat policies within Microsoft Teams revolve around securing the Teams environment from malicious attacks or accidental breaches. They encompass a range of strategies, from user authentication and access control to data protection and incident response. The aim is to mitigate risks while enabling productivity and collaboration.
Microsoft Teams plan threat policies integrate with Office 365’s Advanced Threat Protection (ATP) to offer:
Establish what the acceptable level of risk for your organization is and set this as your security baseline. This involves identifying sensitive or critical data, potential threats, and regulatory requirements.
Use the Microsoft 365 security center to configure ATP policies for Safe Links and Safe Attachments. These policies must reflect your security baseline.
Configure anti-phishing policies in the Microsoft 365 security center, specifying which users are protected and defining actions on detected phishing attempts.
Train your users on security best practices and inform them about the policies in place, so they understand their role in maintaining a secure ecosystem.
Case Scenario: An employee receives an email in Teams with a link. The Safe Links policy ensures that when they click on that link, ATP checks the URL against a database of known malicious links, and if it’s unsafe, the user is warned or prevented from accessing it.
Example Policy Setup:
Feature | Policy Setting | Action Taken |
---|---|---|
Safe Links | Enabled | Verify links at the time of click |
Safe Attachments | Enabled | Scan for malware in attachments |
Anti-phishing | User impersonation | Alerts and takes action on impersonation |
After defining and implementing plan threat policies, it is essential to track their effectiveness. Microsoft provides administrators with reporting tools to analyze the number of threats detected, types of attacks prevented, and identifies users targeted by attacks. By monitoring these reports, teams can fine-tune their threat policies for optimal protection.
Planning and implementing threat policies in Microsoft Teams is an ongoing process that requires attention to detail and proactive management. As cyber threats evolve, so should your strategies to mitigate them. Using the ATP features within Microsoft Teams and regularly reviewing policy effectiveness will help secure your organization’s collaborative environment.

Safe Attachments is a security feature in Microsoft 365 that scans all inbound email attachments to detect and prevent malware from being delivered to end-users. It works by opening the attachments in a virtual environment and using advanced machine learning algorithms to detect any malicious behavior.
Safe Attachments can be enabled from the Security & Compliance Center in Office 365.
Organizations can customize Safe Attachments policies to meet their specific security needs. This includes setting the severity level for alerts, configuring quarantine options, and specifying which users and domains to apply the policy to.
If a threat is detected, the attachment is automatically blocked, and an alert is sent to the organization’s security team.
Safe Links is a security feature in Microsoft 365 that replaces original URLs in emails and Office documents with a URL that is checked against a list of known malicious URLs. If a URL is found to be malicious, the user is warned of the risk and prevented from accessing the site.
Safe Links can be enabled from the Security & Compliance Center in Office 365.
Organizations can customize Safe Links policies to meet their specific security needs. This includes setting the severity level for alerts, configuring user notifications, and specifying which users and domains to apply the policy to.
If a URL is found to be malicious, the user is warned of the risk and prevented from accessing the site.
Yes, Safe Attachments and Safe Links can be used together to provide comprehensive protection against a wide range of security threats.
Organizations should regularly monitor Safe Attachments and Safe Links alerts to identify any potential threats and take appropriate action to prevent further damage. This can be done through the Security & Compliance Center in Office 365.
Both Safe Attachments and Safe Links are included as part of Microsoft 365’s advanced security features, and there is no additional cost associated with enabling them.
In addition to Safe Attachments and Safe Links, Microsoft 365 also offers features such as Advanced Threat Protection, Information Protection, and Azure Active Directory.
Organizations can provide regular security training and awareness programs to ensure their employees are aware of the latest threats and best practices for staying secure.
