Microsoft SharePoint is used for document collaboration and knowledge sharing, as well as workflow automation, and it enables teams to work together efficiently across departments and locations.
However, the same flexibility that makes SharePoint powerful can also introduce SharePoint security mistakes when governance and access controls are not clearly defined. Without the right policies and configuration, organisations may unknowingly expose sensitive information, create permission chaos, or allow site sprawl that makes content difficult to manage.
Many of these common SharePoint mistakes stem from governance gaps rather than technical failures. The good news is that most SharePoint security issues are not caused by sophisticated cyberattacks but by common configuration and governance mistakes.
Most Common SharePoint Security Mistakes, and How They Can be Avoided:
The following SharePoint security and governance mistakes are frequently seen in growing environments where collaboration expands faster than controls.
Granting SharePoint Permissions Directly to Users:
One of the most common SharePoint governance mistakes is assigning permissions directly to individual users. While this may seem convenient initially, it quickly becomes difficult to manage as the number of users grows. Now this causes-
- Issues to track who has access to which files
- Track former employees or role changes with outdated permissions
- Increased risk of accidental data exposure
Use role-based access control (RBAC) and SharePoint groups instead of individual permissions.
| Best practise | Why it helps |
| Use SharePoint groups | Simplifies permission management |
| Assign permissions by role | Maintains consistency across teams |
| Regularly review group membership | Ensures access remains up to date |
Broad-Spectrum Access to SharePoint Content:
While broad permissions may appear to improve collaboration, they can significantly increase the risk of sensitive information being accessed or shared incorrectly.
- Risks of excessive permissions
- Sensitive files visible to unintended users
- Increased likelihood of accidental data leaks
- Higher exposure during security incidents
Follow the principle of least privilege to prevent this:
- Give users only the access required for their role
- Conduct regular permission reviews
- Remove outdated permissions promptly
- Even small permission adjustments can significantly improve SharePoint security.
Unsure how exposed your SharePoint environment is?
A quick security consultation can highlight risks without disrupting users.
Lack of SharePoint Governance leading to Site Sprawl:
Without governance policies, SharePoint environments often grow uncontrollably. Teams may create multiple sites for similar purposes, duplicate files, and leave unused sites active. SharePoint site sprawl creates several operational problems.
- Hundreds or thousands of unmanaged sites
- Duplicate documents are stored across multiple locations
- Difficulty locating the correct version of a file
- Governance Best Practices
- Establish site creation approval processes
- Use clear naming conventions
- Assign owners responsible for each site
- Archive unused sites regularly
A well-defined governance framework helps maintain a clean and organised SharePoint environment.
Weak Authentication and Account Security:
Account security remains one of the most important factors in protecting SharePoint environments. Weak passwords or missing authentication controls can allow attackers to gain access to sensitive data if credentials are compromised. Common authentication risks:
- Weak or reused passwords
- Phishing attacks targeting employees
- Lack of multi-factor authentication (MFA)
This can be avoided by:
| Security Measure | Benefit |
| Enable multi-factor authentication | Adds an extra verification layer |
| Implement strong password policies | Reduces credential compromise risk |
| Provide phishing awareness training | Helps employees detect threats |
Strengthening identity security is one of the simplest ways to reduce SharePoint risk.
Poor Data Classification and Protection:
SharePoint often stores highly sensitive business information. If documents are not classified correctly, employees may unintentionally share confidential files. This can create compliance issues, particularly for organisations handling regulated data. Risks include-
- Confidential data shared incorrectly
- Employees unsure how to handle sensitive documents
- Regulatory compliance violations
- Recommended Solutions
Data classification categories include public, internal, confidential, and restricted. How can they be handled?
- Apply sensitivity labels and data protection policies
- Train employees on proper document handling
- Clear classification policies help ensure sensitive information remains protected.
- Breaking Permission inheritance frequently
SharePoint allows administrators to break permission inheritance for specific folders or libraries. While useful in certain situations, excessive use can create complicated permission structures.
Over time, this complexity makes it difficult to understand who has access to what, leading to confusion around access structures, increased risk of misconfigured permissions, and more time spent managing access rights. This can be avoided by keeping permission structures simple and maintaining inheritance whenever possible.
Poor Monitoring and Auditing of SharePoint Activity
Without monitoring, suspicious activities such as unusual file downloads or permission changes may go unnoticed.
Monitoring is necessary to detect-
- Detect unauthorised access quickly
- Identify unusual user behaviour
- Improve incident response capabilities
- Monitoring Best Practices
- Enable SharePoint audit logging
- Configure alerts for high-risk activities
- Regularly review audit reports
Monitoring provides valuable visibility into how data is being accessed and shared.
Blocking External sharing without Secure Alternatives:
Some organisations disable external sharing entirely to avoid security risks. Unfortunately, this often creates unintended consequences. Employees may resort to personal email accounts or unsanctioned file-sharing tools to collaborate with partners.
This behaviour, known as shadow IT, can create even greater security risks.
Instead of disabling sharing completely, configure secure sharing controls.
| Secure Sharing Method | Benefit |
| Require authentication for shared files | Ensures only verified users access content |
| Use expiring sharing links | Limits long-term access |
| Restrict sharing to trusted domains | Reduces external risk |
This allows collaboration while maintaining control over sensitive information.
Lack of SharePoint Security Training for Users:
Technology alone cannot guarantee security. Even the best security tools can fail if employees do not understand how to use them correctly. Many SharePoint incidents occur simply because users are unaware of security best practices.
Security training reduces accidental data leaks, improves awareness of phishing threats and encourages responsible data handling. Training should include secure document sharing practices, password and authentication best practises and finally the ability to recognise suspicious activity
These SharePoint permission issues often escalate into long‑term access control problems if not governed centrally.
How Do you Build a Secure SharePoint Environment?
SharePoint can be an incredibly powerful collaboration platform, but its effectiveness depends on proper governance and security practices. Organisations that proactively address common mistakes such as poorly managed permissions, lack of monitoring, or weak authentication can significantly reduce their risk exposure.
A strong SharePoint governance strategy should include:
- Clear permission structures
- Defined data classification policies
- Active monitoring and auditing
- Regular user training
- Controlled external sharing
By addressing SharePoint security mistakes through consistent governance, organisations can reduce risk without slowing collaboration.
