In organisations where information security is a priority, access control has become a crucial element in protecting sensitive data. Document management platforms, which store and organise large volumes of documents, need robust mechanisms to ensure that only authorised users can access specific information. This article examines the components of access control (authentication, authorisation and logs), best practices, strong authentication and account management from when users join until they leave, on document management platforms.
What is access control?
Access control refers to the process of restricting and managing who can view, edit or delete documents on a document management platform. This process involves defining permissions based on different criteria, such as the user’s role, the location of the document and the confidentiality level of the information.
Components of access control
- Authentication: Verifies the user’s identity through credentials, such as a username and password, or more advanced methods, such as multi-factor authentication.
- Authorisation: Determines the permissions the user has after authentication, such as accessing, editing or sharing specific documents.
- Access logs: Keeps a record of who accessed which documents, when and for what purpose.
Why access control matters on document management platforms
Implementing an efficient access control system is vital to protecting an organisation’s digital assets. Such a system not only protects information but also promotes more efficient document management.
Protecting sensitive data
In any organisation, some documents contain highly sensitive information, such as financial data, confidential contracts or the personal data of employees and clients. Access control therefore ensures that only authorised people have access to these documents, reducing the risk of information leaks.
- Protection against insider threats: Not every employee needs access to every document. Access control prevents unauthorised users from accessing information outside the scope of their work.
- Security against external threats: In the event of a security breach, access control limits the damage, because it makes it harder for attackers to reach critical information.
Regulatory compliance
Many sectors are subject to strict rules on privacy and information security, such as the GDPR (General Data Protection Regulation) in Europe. Access control helps organisations comply with these rules by ensuring that only authorised people can access confidential data and that all access is logged for auditing.
- Compliance documentation: During audits, organisations can demonstrate that they have effective mechanisms to protect sensitive information, minimising the risk of fines and penalties.
- Access rights management: Platforms allow access rights to be defined and adjusted in line with legal and regulatory requirements, ensuring that information is managed in accordance with good practice.
Improving organisational efficiency
Access control is not just a matter of security but also of efficiency. By ensuring that employees only have access to information relevant to their roles, organisations can improve workflow and reduce the time spent on unnecessary tasks.
- Optimised workflows: With restricted access to specific documents, employees can focus better on their tasks, increasing productivity.
- Fewer errors: Reduces the risk of human error by limiting the editing or deletion of documents to users with the necessary knowledge and authorisation.
Best practices for implementing access control
Implementing an effective access control system involves following a few best practices that ensure security and efficiency in document management.
Defining access policies
Establishing role-based access policies is one of the most effective approaches. Each role (for example, manager, employee, auditor) has a set of permissions that defines what the user can and cannot do within the platform.
- Granular permissions: Tailor permissions to ensure that each user has only the level of access needed to perform their duties.
- Segmentation by department: Define permissions based on the different organisational units, ensuring that relevant documents are accessible only to the departments responsible.
Using multi-factor authentication (MFA)
Multi-factor authentication adds an extra layer of security by requiring users to confirm their identity through two or more authentication methods, such as passwords, codes sent by SMS, authenticator apps or biometrics.
- Greater security: Significantly reduces the risk of unauthorised access, even if a user’s credentials are compromised.
- Ease of implementation: Most modern document management platforms support MFA, making it simple and effective to implement.
Regular monitoring and auditing
Continuous monitoring of access and regular audits are essential to ensure that access control policies are working as expected.
- Log analysis: Regularly review the access logs to identify suspicious or anomalous behaviour that could indicate an attempted security breach.
- Permission adjustments: Carry out periodic audits to ensure that access permissions are aligned with employees’ current responsibilities.
Employee training and awareness
Finally, it is essential that employees understand the importance of access control and know how to use the document management platform securely.
- Regular training: Provide training on security best practices and the importance of keeping access credentials secure.
- Responsible use policies: Implement clear policies that define responsible use of the platform and the consequences of failing to comply with them.
Access control models
In practice, there are several models for assigning permissions. The most common is role-based access control, known as RBAC: each profile, such as safety technician, site manager or auditor, has a set of permissions, and each user receives one or more profiles. On the other hand, attribute-based access control, or ABAC, makes decisions based on characteristics of the user, the document and the context, such as the site, the company or the confidentiality level. In any model, the principle of least privilege should apply: each person has only the access they need for their duties, and only for as long as necessary.
Joiners, movers and leavers
Many access problems arise when people change roles or leave the organisation. It is therefore advisable to define a process for three moments: joining, when initial profiles are assigned; changing roles, when old access is removed; and leaving, when the account is deactivated on the same day. In addition, access for external contractors should have an end date linked to the duration of the contract.
Strong authentication
Not all multi-factor authentication methods are equally robust. SMS codes are better than nothing, but they can be intercepted or diverted. Whenever possible, it is therefore advisable to prefer authenticator apps, FIDO2 security keys or passkeys, which are more resistant to phishing. Likewise, single sign-on with the company directory simplifies management and allows all access to be deactivated at once.
Practical example: A technician who changes role
Consider a technician who moves from the document validation team to the sales department. Without a defined process, they would still be able to see fitness-for-work certificates and worker data. With the role change process, by contrast, the manager requests the profile change and the platform removes the old access the same day. As a result, the company complies with the principle of least privilege and reduces the risk of improper access to personal data.
Access control checklist
- Role-based profiles with minimum permissions.
- Mandatory multi-factor authentication, preferring phishing-resistant methods.
- Documented joiner, mover and leaver process.
- Contractor access with an end date.
- Access review at least every six months.
- Access logs retained and analysed.
Common mistakes to avoid
A frequent mistake is giving administrator profiles to users who do not need them. Another mistake is sharing accounts between several people, which makes it impossible to know who performed each action. In addition, many organisations forget to deactivate the accounts of former employees and contractors.

Frequently asked questions
How often should we review access?
At least every six months and whenever roles change. For profiles with access to sensitive data, reviews should be more frequent.
Conclusion
Access control is a fundamental pillar of security and efficiency on document management platforms. By implementing robust access control policies, organisations not only protect sensitive data against unauthorised access but also improve regulatory compliance and operational efficiency. With effective authentication, authorisation and monitoring practices, companies can ensure that their information is secure and that their employees have quick, easy access to the documents they need to do their work.
