Microsoft 365 Cloud Security Review

Microsoft 365, widely used in organizations large and small, provides security, yet under the Shared Responsibility Model, securing its configuration remains primarily the user's responsibility.

What is a Microsoft 365 Cloud Security Review?

Microsoft 365, a widely used cloud-based business tool, provides security, but as per the Shared Responsibility Model, configuring it securely is primarily your responsibility.

In its default state, many of the controls do not make best use of the inbuilt security features. Sadly attackers are equally aware of this and often use weak configuration settings to perform attacks against users.

For example, using the default Legacy Authentication Protocols (POP and IMAP) completely negates any security provided by Multi-Factor Authentication.

In a Microsoft 365 Configuration Review, we can identify and advise on potential risks. We can help move your Microsoft 365 Tenancy towards best practice and security compliance.

Key Assessment Areas

Embarking on a Microsoft 365 Cloud Configuration Review is essential to meticulously assess and enhance the security, efficiency, and compliance of your Azure environment, for a broad range of reasons.

Email
Security

In Microsoft 365, email is a prime target for phishing. Robust configurations thwart common techniques, while admin visibility aids in swift incident response.

Data Management and Storage

Secure your sensitive data with proper Data Loss Prevention (DLP) and Classification controls. Fundamental to Information Risk Management, they ensure control and protection.

Event and Security Auditing

Audit essential for investigations. Ensuring accurate data auditing is key to understand incident impact and identify malicious activity promptly.

Mobile Device Management

Enable device security policies for continuous data access. Uphold confidentiality with PIN requirements, device restrictions, and the ability to remotely wipe lost or stolen devices.

Exisiting Accounts

Reviewing the account structure reveals issues in fundamental processes. Ensuring administrative collaboration and minimizing privileged accounts helps reduce the organizational attack surface.

Authentication

Securing authentication is crucial to mitigate malicious access risks. Reviewing mechanisms ensures controls align for robust security, preventing contradictions and vulnerabilities, like Legacy Protocols lacking MFA support.

Application Permissions

Microsoft 365's broad capabilities and third-party integrations attract attackers. Reviewing permissions is crucial to maintain control, preventing data exposure or malicious file sharing.
