Microsoft 365 brings together the power of productivity tools like Teams, SharePoint, and OneDrive to improve collaboration for businesses. However, the increasing dependency on these digital platforms also exposes them to numerous security threats. Therefore, security operations analysts must be skilled in investigating, responding, and remediating threats to Microsoft Teams, SharePoint, and OneDrive.
Investigating Threats to Microsoft Teams, SharePoint, and OneDrive
Microsoft has robust tools that enable its Security Operations Analysts to investigate threats effectively. Microsoft Threat Protection not only allows for the detection of attacks across Microsoft 365 but also enables correlation and prioritization of alerts, allowing for the investigation into true threats.
For example, if a suspicious file is downloaded through a team chat in Teams, the threat protection suite automatically analyzes the file, alerting the analyst if it is malware. The analyst can view all related alerts linked to the file. All file activities, such as who downloaded, moved, or was attacked by the file, become instantly visible.
For SharePoint and OneDrive, the audit log search in the security and compliance center is a great place to start the investigation. The audit log records user activity enabling analysts to understand activities that may have led to security incidents.
Responding to Threats to Microsoft Teams, SharePoint, and OneDrive
Once threats are identified, it is crucial for analysts to respond swiftly to contain them. Microsoft Integrated Security Solutions like Microsoft Defender ATP, provide incident response capabilities. These capabilities include quarantining suspicious files, restricting access, or blocking compromised user accounts from accessing Teams, SharePoint, and OneDrive.
A response example could be a warning flag raised by a suspicious file in OneDrive. The Microsoft Defender ATP can quarantine the file immediately, eliminate access, and notify users interacting with the file about the possible danger.
Similarly, if a SharePoint site is found disseminating a malicious link, analysts can delete the link and restrict access to the site while further investigations are conducted.
Remediation of Threats to Microsoft Teams, SharePoint, and OneDrive
To recover from any security incident, analysts need to remediate and reverse the effects of the threat. In Microsoft 365, this can be done using built-in remediation processes.
In Teams, for instance, if an account is found to be compromised, it can be recovered by resetting the password and reviewing recent activity on the account for any unusual patterns. If any are found, they can be reverted.
For SharePoint and OneDrive, a file restore feature can be used to restore files to a previous state before the security breach incident to recover lost data.
Conclusion
Knowledge in investigating, responding to, and remediating threats to Microsoft Teams, SharePoint, and OneDrive is essential for SC-200 Microsoft Security Operations Analyst exam aspirants. The functionality of Microsoft 365 suite provides robust security tools that allow you to effectively handle these threats and protect your organization’s assets.
