Office 365 is a popular cloud-based productivity suite that offers many benefits for businesses of all sizes. These Top 5 Security Settings in O365 should help you get started on your path towards a more secure cloud. However, with great power comes great responsibility. As an O365 administrator, you need to ensure that your organization’s data and users are protected from cyber threats and unauthorized access. In this blog post, we will share with you the top 5 security settings in O365 that you should configure to enhance your security posture and reduce your risk exposure.
1. Enable multi-factor authentication (MFA). MFA is a simple but effective way to prevent account compromise by requiring users to provide an additional factor of authentication besides their password, such as a code sent to their phone or email, or a biometric verification. MFA can stop attackers from accessing your O365 account even if they have your password. You can enable MFA for all users or specific groups in the Azure Active Directory portal.
2. Set up conditional access policies. Conditional access policies allow you to control who can access what resources in O365 based on certain conditions, such as location, device, app, or risk level. For example, you can block access to O365 from untrusted locations or devices, or require MFA for high-risk sign-ins. You can create and manage conditional access policies in the Azure Active Directory portal.
3. Configure data loss prevention (DLP) policies. DLP policies help you prevent sensitive data from leaving your organization or being shared with unauthorized parties. You can define what types of data are sensitive, such as credit card numbers, social security numbers, or health records, and what actions are allowed or blocked when such data is detected in O365 apps, such as Outlook, SharePoint, OneDrive, or Teams. You can create and manage DLP policies in the Microsoft 365 compliance center.
4. Enable audit logging and alerts. Audit logging and alerts help you monitor and respond to suspicious or malicious activities in your O365 environment. You can view and search audit logs for various events, such as user sign-ins, file downloads, mailbox access, password changes, or admin actions. You can also set up alerts to notify you when certain events occur, such as a user logging in from an unusual location or a file containing sensitive data being shared externally. You can access audit logs and alerts in the Microsoft 365 security center.
5. Review and update your security settings regularly. Security is not a one-time task but an ongoing process. You should review and update your security settings regularly to keep up with the changing threat landscape and best practices. You can use the Microsoft Secure Score tool to assess your current security posture and get recommendations on how to improve it. You can also use the Microsoft Security Roadmap to plan and prioritize your security initiatives. You can access both tools in the Microsoft 365 security center.
These are some of the most important security settings in O365 that you should configure to protect your organization’s data and users. By following these steps, you can enhance your security posture and reduce your risk exposure in the cloud.
