Security Assessment and Solutioning with Microsoft 365 Security and Compliance Center


This is a deep dive into Microsoft 365 Security and Compliance center OOTB reports and more importantly what potential solutions may be evolved after analysing those reports indicating the current security posture of the enterprise.

The discussion is intended as a multipart series starting with the various reports available and what they mean to the organization. Beyond that, a set of possible solution schemes are fielded based on our current experience in live projects.

Read on!

Few Important Reports

The Security & Compliance Center enables organizations to manage data protection and compliance. The prerequisite is to have the appropriate license and permission, for the security dashboard to enable checking and analysing security and threat protection status in the tenant.

Depending on what your organization’s subscription includes, the Security Dashboard includes several widgets, some of the most prominent features are the Threat Management Summary, Threat Protection Status, Global Weekly Threat Detections, Malware. The commonly used reports are described in short.

Compromised User Report

This report is available in Microsoft 365 organizations with Exchange Online mailboxes. It’s not available in standalone Exchange Online Protection (EOP) organizations.

This report shows the number of user accounts that were marked as suspicious or restricted within last 7 days. These are accounts with problematic or in compromised state. Security and compliance center through Identity and access management and unified audit logging event can track these suspicious user accounts peeping in your organization. To prevent these user account compromise microsoft recommends enforcing modern authentication aka MFA(multi factor authentication). Along with normal auditing, mailbox auditing is also supported in remediation process.

Encryption Report

The Encryption report is available in EOP (subscriptions with mailboxes in Exchange Online or standalone EOP without Exchange Online mailboxes). Organization’s security team can use this report to identify patterns and proactively apply or adjust policies for sensitive email messages.

M365 can identify sensitive information in email and with the help of mail flow rule(aka transport rule) then it can apply auto encryption. Azure rights management has a built in service named as Office 365 Message Encryption (OME) which enforces the encrypted message transport and improve this report score. Microsoft 365 also provides IRM(Information rights management) as an encryption solution that applies usage restrictions on emails along with S/MIME (Secure/Multipurpose Internet Mail Extensions) which is a certificate-based encryption solution that allows you to both encrypt and digitally sign a message. Encryption with Rights Protection can be leveraged to reduce the ability for users that receive encrypted messages to forward them to unintended recipients, print, or access them within certain time restrictions.

To view this report, open the Security & Compliance Center, go to Reports > Dashboard and select Encryption report.

To view the report, open the Security & Compliance Center, go to Reports > Dashboard and select Malware detections in email.

Malware and Spam Detection

The malware detection report tracks the incoming and outgoing email messages and gives report about malware’s presence there. This is part of exchange online protection (EOP). The Spam detections report shows spam email messages that were blocked by exchange online protection or EOP. Messages are counted individually, not per recipient.

Using O365 Manager Plus, admins can comprehensively monitor all inbound and outbound traffic in their Exchange Online environment and get scheduled reports on spam and malware detections. Admins can also set alert notifications for early detection so they can take immediate steps to remediate any such issues. Enabling mailbox auditing is a crucial and finegrained steps to take control of malwares and spams flowing in users mailbox.

Spoof Detection Report

Spoof detection report contains information about how many spoof messages have been detected. Based on this report your organization can implement anti spoofing protection by EOP.

Spoof intelligence in the Security & Compliance Center on the Anti-spam settings page helps to review all senders who are spoofing sender email addresses in your organization’s email domains or spoofing sender email addresses in external domains. We can define Spoofing Filter Rule which help limit the amount of phishing emails that are delivered.

To view the report, open the Security & Compliance Center, go to Reports > Dashboard and select Spoof detections.

Threat Protection Status Report

This report is available in both EOP(Exchange online protection) and Office 365 ATP. This report provides info about malicious content detected with email messages like files or urls those were blocked by anti-malware engine or ATP anti phising.

Depending on the type of subscription this report helps us with below facts on the context of therat management.

EOP but not Microsoft Defender for Office 365Malicious email that was detected and blocked by Exchange Online Prtection (EOP)
Microsoft Defender for Office 365Malicious content, emails detected and blocked by EOP and aggregated count of unique email messages with malicious content blocked by the anti-malware engine.

In this limited sphere it is not possible to discuss all these different features in details, so I will highlight security, compliance and threat management dashboard.

Now to access the mentioned reports you must have an appropriate role assigned for both the Security & Compliance Center and the Exchange admin center.

You must be a global administrator, a security administrator, or a security reader to view the Security Dashboard.

This security and compliance overall scores give holistic insight to an organization’s security perspective in Office 365 environment. The Secure Score is assigned based on the security configurations and activities enabled in an Microsoft 365 environment. As an admin you can analyze current score compared to the maximum score. Though a perfect Secure Score doesn’t provide absolute guarantee that an organization’s security won’t be breached, it does ensure that admins have taken necessary steps towards mitigating the risk of such known security breaches.

Security & Compliance Proposed Solutioning

So, now you know how the Compliance Centre may be used to assess your current security posture. But the job starts there. You need to identify and implement pertinent security solutions based on your alert level and business requirement.

Some of the baseline solutions which can be implemented to minimize the security risks and augment compliance score are highlighted below in short. Discussing those in details would be the focus of my future articles in this area.

  1. Creating solution for auto classifying and labelling the files based on sensitive type it contains.
  2. Leverage Microsoft information protection(MIP) labels to protect files and emails residing in cloud.
  3. Employing appropriate DLP policies to track and prevent any leak and data breach.
  4. Using label analytics to control how sensitive and retention labels are being used.
  5. Implement Conditional access policy for guest and external users in Microsoft 365 cloud apps such as Microsoft Teams, Exchange Online, and SharePoint.
  6. Using Microsoft cloud access security (MCAS) solution for elevating security posture by taking control of your cloud applications and services
  7. Using Intune’s security baselines to help secure and protect your users and devices.
