The valuable insights into data and user behavior across your cloud services give you visibility and control over your environment.
Identifying Security Risks
Microsoft Defender for Cloud Apps leverages billions of daily inputs from diverse sources such as endpoints, user activities, files, and more. These disparate data sources are unified in their system where they implement behavioral analytics and anomaly detection to understand normal versus risky behavior.
Security alerts can be categorized under the following broad types:
- Anomalous behavior: This includes risky behaviors such as mass download by a user or multiple failed login attempts.
- Privileged account activity: This involves potentially risky activities performed by privileged accounts.
- DLP policy violation: This includes alert regarding potential data leaks.
- Compliance violation: Any issues that may lead to non-compliance with industry regulations.
Investigating Security Risks
Once you have identified the security risks, you can deep dive into the details provided by Microsoft Defender for Cloud Apps to investigate further. For instance, you can see who are the users associated with the alert, their past activities, and other pertinent details.
Following are the steps to investigate a risk detected by the system:
- In the activity log, filter out the activity or user you want to investigate.
- After filtering, choose a specific activity to see more details.
- A pop-up will show details associated with the activity including users, device info, IP address, date and time of activity, and other specifics.
- If the issue seems dangerous after investigation, you can create a policy to monitor similar future activities.
Remediation of Security Risks
Remediating security risks is the final step in securing your cloud application environment. Microsoft Defender for Cloud Apps allows you to implement remedial actions for identified risks.
Actions you can take for instance-made alerts include:
- Suspend user: If you detect a user involved in a suspicious activity, you can suspend their account.
- Require user to sign in again: To verify the user, you can force them to sign in again.
- Make user change password: If you suspect the user’s password is compromised, compel them to change the password.
- Reset user session: If you find a user session suspicious, you can reset it.
