Best Practices for Office 365 Security Monitoring

Microsoft Office 365 has largely defined how teams collaborate in the cloud. Today, it’s the most widely used cloud application suite by organizations, with over 100 million monthly active users worldwide.

For many organizations, Office 365 marks an entry point into cloud computing—and with it, cloud security. As organizations migrate sensitive and business-critical data to the Microsoft cloud, many security concerns arise: Is our data secure? Who has access to it, both internally and externally? What if unauthorized users compromise account credentials? How can we detect ransomware and other malware in Office 365? What do we need to do to maintain compliance?

According to the 2017 Cloud Security Spotlight Report conducted by the Information Security Community on LinkedIn, the top three cloud security concerns are protecting against data loss (57%), threats to data privacy (49%), and breaches of confidentiality (47%).

With these cloud security concerns in mind, organizations must take steps to secure and monitor their Office 365 environments. Fortunately, organizations can leverage security monitoring capabilities provided by Microsoft and other security management vendors like AlienVault® to ease Office 365 security monitoring.

In this white paper, we’ll look at security monitoring best practices for Office 365, including what types of activities you should monitor, what types of threats to look for, and what tools you should use to do so.
