App Permissions in Business: How to Stay in Control
Unmanaged app access could be the backdoor cybercriminals are waiting for. Here’s how to shut it before it’s too late.
What’s the Real Risk?
If you’re a business owner in Atlanta, especially in sectors like law, real estate, finance, or manufacturing, you’re likely focused on day-to-day operations. But here’s something that could be quietly undermining your data security:
In Microsoft 365 environments, default settings often allow users to approve third-party apps. These apps can read emails, access documents, or even send messages—all without admin oversight.
This creates three serious risks:
- Data leaks: Sensitive files and emails could be exposed.
- Compliance issues: Violates regulations like HIPAA, GDPR, or CCPA.
- Security vulnerabilities: Attackers use these apps to bypass traditional defenses.
What Are Third-Party App Permissions?
Third-party apps are tools like CRM integrations, calendar plugins, or AI assistants. While they improve productivity, many request access to sensitive data:
- Read/write access to Outlook and OneDrive
- Full mailbox permissions
- Directory (user info) access
- Teams chat and file integrations
These apps gain access through something called OAuth permissions. Once a user clicks “Accept,” that app may have persistent access to company data.
Why Small Businesses in Atlanta Are at Risk
Atlanta’s small businesses often run lean IT operations—or none at all. Without a managed IT strategy, these security gaps remain invisible until a breach occurs.
Common challenges:
- No centralized IT admin
- Default Microsoft 365 security settings
- Employees unaware of risks
- Lack of app permission monitoring
Industries like legal, financial services, and healthcare are especially vulnerable due to regulatory compliance requirements.
Real-World Consequences
📧 Email Leaks
A marketing employee installs a calendar scheduling app that syncs with Outlook. That app requests access to full inbox content and sends data to external servers.
📁 Confidential File Access
A “free” PDF editor connects with OneDrive and gains permission to read and edit files across the business. Sensitive contracts or patient records are exposed.
👤 Identity Theft
Some apps request directory permissions—giving them access to names, job titles, and contact details. This data can be used in spear-phishing attacks.
3 Essential Steps to Regain Control
Let’s break this down into simple, actionable steps:
✅ Step 1: Disable User Consent to Apps
By default, Microsoft 365 allows users to grant app permissions. You need to turn this off.
How to do it:
- Go to Microsoft Entra (formerly Azure Active Directory) > Enterprise Applications.
- Click “Consent and Permissions.”
- Set User Consent for Apps to “Do not allow user consent.”
🔒 Benefit: Prevents unauthorized apps from connecting to business data.
✅ Step 2: Enable Admin Approval Workflows
Instead of blocking all apps, you can set up a system where employees can request access—and IT/admin can approve or reject.
How to do it:
- In Microsoft Entra, enable the Admin Consent Workflow.
- Add business decision-makers as approvers.
- Monitor app access requests and log approvals.
💡 Pro Tip: Create guidelines for what types of apps are acceptable.
✅ Step 3: Review and Revoke Existing Permissions
Don’t just focus on new apps. Review what’s already installed.
How to do it:
- Go to Microsoft Entra > Enterprise Applications.
- Sort by Permissions Granted.
- Remove any apps that are:
- No longer used
- Not business-critical
- From unknown publishers
🧹 Cleanup Tip: Do this quarterly to keep your environment safe.
👁️🗨️ Bonus: Monitor for Shadow IT
Not all risky apps show up in Microsoft logs. Employees may use personal devices to connect third-party tools.
To prevent this:
- Enable Cloud App Security or Microsoft Defender for Cloud Apps.
- Get alerts for unauthorized apps.
- Block unapproved domains and services.
Benefits of Managing App Permissions
Taking control of app access brings immediate advantages:
- ✔ Enhanced Security: Block malicious or vulnerable apps that hackers could exploit.
- ✔ Better Compliance: Stay aligned with industry regulations and avoid fines.
- ✔ Operational Visibility: Know exactly what tools are being used in your environment.
- ✔ Fewer Surprises: No more “I didn’t know we were using that” moments.
Who Should Be Doing This?
If your business falls into any of these categories, it’s time to take action:
- Law firms managing confidential client files
- Real estate agencies using cloud-based listing tools
- CPA and accounting firms working with sensitive financial data
- Medical and veterinary clinics handling HIPAA-protected info
- Consulting firms storing proposal templates and NDAs
- Nonprofits handling donor data and payment records
Even businesses with just 5 to 10 employees can benefit from enforcing proper app permission controls.
