Why Human Error is the Biggest Risk in M365 Security

6 min. readlast update: 09.21.2024

Microsoft 365 (M365) is a widely adopted platform offering a range of productivity tools that allow employees to collaborate, communicate, and manage data more efficiently. While M365 offers built-in security features to help protect sensitive data, human error remains one of the biggest security risks. Misconfigurations, improper permissions, accidental data sharing, and unintentional oversights can open the door to security vulnerabilities that cybercriminals are quick to exploit.

In this article, we’ll explore why human error poses such a significant risk to M365 security, common mistakes that can compromise your organization’s data, and how Griffin31 can help mitigate these risks by automating security assessments, detecting misconfigurations, and providing real-time alerts.

The Impact of Human Error on M365 Security

Human error is consistently cited as one of the leading causes of data breaches. In a platform as robust and complex as M365, users and administrators are prone to making mistakes that can have significant security implications. Below are some common areas where human error can lead to vulnerabilities in M365:

1. Misconfigurations
M365 has a vast array of settings that govern permissions, data sharing, access controls, and compliance configurations. A single misconfiguration, such as enabling too much access to a sensitive SharePoint folder or misconfiguring Multi-Factor Authentication (MFA), can expose critical data.

- Example: An administrator mistakenly grants full access to a user group for a sensitive document library, allowing unauthorized employees to view confidential information.

2. Improper Permission Management
M365 relies on Role-Based Access Control (RBAC) to manage who can access various resources like files, emails, and applications. Improperly assigning roles or not regularly reviewing permissions can leave sensitive data exposed to users who don’t need access.

- Example: A user is assigned global administrator privileges that aren’t necessary for their role, increasing the risk of unauthorized access to critical settings and data.

3. Accidental Data Sharing
The ease of collaboration in M365, particularly through OneDrive, SharePoint, and Teams, makes it simple to share files both internally and externally. However, employees can accidentally share sensitive information with the wrong individuals or external users.

- Example: An employee inadvertently shares a confidential file with external partners by selecting "Anyone with the link" instead of limiting access to internal team members.

4. Overlooked Security Settings
M365 has many security settings that require careful configuration and continuous monitoring. Administrators can easily overlook or fail to update these settings, leaving the organization exposed to evolving threats.

- Example: Security settings such as email encryption, data loss prevention (DLP), or Safe Links are disabled by default, and an admin fails to enable them.

5. Lack of Continuous Monitoring
Without continuous monitoring, any accidental changes or human errors in security configurations may go unnoticed, potentially exposing the organization to risks for weeks or months.

- Example: An administrator makes a change to the email filtering settings, inadvertently allowing malicious emails to bypass security protocols.

Why Human Error is a Persistent Risk in M365

Even with robust training programs and policies in place, human error will always be a factor in any system that relies on manual input and decision-making. This is particularly true in dynamic environments like M365, where administrators manage complex settings across multiple tools, and employees can unintentionally share sensitive data in the course of daily operations.

- Volume of Settings: M365's vast number of settings across SharePoint, OneDrive, Teams, Exchange, and other services can easily lead to oversight or misconfiguration.
- Constant Change: M365 is constantly evolving, with new features and settings being introduced regularly. Keeping up with these changes can be challenging for IT teams.
- User Actions: End users, who may not be security experts, are frequently responsible for managing document sharing and collaboration, increasing the likelihood of accidental data exposure.

How Griffin31 Can Help Mitigate Human Error in M365 Security

To address the risks posed by human error, organizations need a way to automate security checks, continuously monitor for misconfigurations, and alert administrators to potential vulnerabilities. This is where Griffin31 comes into play.

Griffin31 is designed to automate the process of assessing M365 security configurations, helping organizations quickly identify and remediate issues caused by human error. Here’s how Griffin31 can help:

1. Automated Security Assessments
Griffin31 automatically scans your M365 environment for misconfigurations, ensuring that settings are aligned with security best practices. This eliminates the need for manual checks, reducing the risk of errors.

- Benefit: Automated scans catch common human errors, such as improper permissions, weak authentication settings, or misconfigured sharing options, before they lead to data breaches.

2. Real-Time Alerts for Security Changes
Griffin31 continuously monitors your M365 environment and provides real-time alerts when critical security configurations are modified. This ensures that any accidental changes are detected immediately, giving administrators the ability to respond quickly.

- Benefit: Real-time alerts notify IT teams of changes in security settings, allowing for prompt investigation and remediation of potential vulnerabilities.

3. Misconfiguration Detection
Griffin31 identifies security misconfigurations that could be introduced by human error, such as overly permissive sharing, missing MFA, or excessive administrative privileges.

- Benefit: Misconfiguration detection reduces the chance that employees or administrators will unintentionally expose sensitive information, ensuring that the organization’s security posture remains strong.

4. Regular Compliance Checks
With Griffin31, you can ensure that your M365 environment complies with industry regulations such as GDPR, HIPAA, and ISO 27001. Regular compliance checks ensure that critical security controls, such as data encryption and DLP, are consistently in place.

- Benefit: Regular compliance checks help prevent fines or penalties due to compliance violations caused by human error or misconfigurations.

5. Automated Role and Permission Reviews
Griffin31 helps administrators regularly review user roles and permissions, ensuring that unnecessary or excessive access is promptly removed. This is particularly important for privileged accounts, which pose a high security risk if improperly managed.

- Benefit: Automated role reviews reduce the risk of privilege creep, where users accumulate unnecessary permissions over time, potentially leading to unauthorized access.

Common Human Errors that Griffin31 Can Help Prevent

Here are a few examples of how Griffin31 can help prevent common security issues caused by human error in M365:

- Sharing Sensitive Files with External Users: Griffin31 can detect and alert you when files are shared externally without proper security controls, such as requiring authentication or expiration dates.
  
- Overly Permissive Admin Access: Griffin31 identifies accounts with unnecessary administrative privileges, ensuring that only authorized users can make critical changes to the environment.
  
- Misconfigured Email Security: Griffin31 can detect when email security settings, such as Safe Links or anti-phishing policies, are disabled or misconfigured, ensuring robust protection against email-based attacks.
  
- Inadequate MFA Settings: Griffin31 ensures that MFA is enabled and enforced for all users, reducing the risk of account compromise due to weak or stolen credentials.

Conclusion

Human error is an unavoidable factor in any system, but its impact can be minimized with the right tools in place. In an M365 environment, where complex configurations and frequent user actions create opportunities for mistakes, relying solely on manual processes can lead to security vulnerabilities.

Griffin31 provides an automated solution that helps organizations reduce the risks associated with human error by continuously assessing security settings, detecting misconfigurations, and alerting administrators to potential issues in real-time. By using Griffin31, organizations can maintain a strong security posture, minimize the risk of data breaches, and ensure compliance with industry regulations, all while reducing the burden on IT and security teams.
