Document Access Permissions and Security: Who Sees What?

Document access permissions and security: who sees what in your organisation?

Digital documents are easier to share, which is both their strength and their risk. A payroll file sent by mistake to a WhatsApp group, or a contracts folder open to every employee, can cause damage that is hard to undo.

How do I protect digital documents and control who can see them?

Classify your documents by sensitivity, give each role the minimum permissions it needs for its work, and use personal accounts protected by strong passwords and two-factor authentication. Switch on access and edit logs, and keep backups that can’t easily be deleted. Review permissions at every job change or departure.

Classifying documents by sensitivity

Public: Can be shared outside the organisation, such as brochures, announcements and public offers.
Internal: Available to staff but not the public, such as procedures, forms and circulars.
Confidential: Only for those who need them, such as contracts, payroll, employee files and customer data.
Highly sensitive: For a very small number of people, such as critical legal documents and strategic financial data, with extra protection.

Principles of permission control

Least privilege: Staff see only what they need for their work, and get any extra access through a documented request.
Role-based permissions: Granted to job groups, such as accounts or HR, rather than to each person individually, so they are easy to change when roles change.
Separate viewing from editing and deleting: Many people need to view, few need to edit, and fewer still need to delete.
Controlled external sharing: Share links with an expiry date and a password, instead of sending files as open attachments.
Access log: Record who opened, downloaded or edited a document, and review the log whenever something looks wrong.

Common risks to watch for

Shared accounts: One account used by several employees makes it impossible to know who did what.
Passing documents around on WhatsApp: Sending photos of contracts and IDs in personal chats leaves copies on many phones outside the organisation’s control. It is a widespread habit that needs a clear policy.
Departing employees: An ex-employee’s account left active, or copies kept on their personal device, is a frequent cause of document leaks.
Unprotected devices: A computer without a password, or a USB drive lost on the way, exposes everything on it.
Exposed passwords: A password written on a note stuck to the screen or sent in a chat cancels out every other control, so use a password manager instead.

Practical steps to secure documents

01
Classify the main folders
Set the sensitivity level of each main folder and the owner responsible for its permissions.
02
Create role-based groups
Then grant permissions to groups rather than individuals.
03
Turn on two-factor authentication
For every account with access to confidential documents, with no exception for managers.
04
Set joiner and leaver procedures
A checklist run when an employee is hired, moved or leaves, covering accounts, devices and links.
05
Review permissions regularly
On fixed dates, remove unused permissions and close old share links.

Who gets which permission? A simple example

Folder	View	Edit and delete
Procedures and forms	All staff	Quality officer or management
Contracts	Management, finance and the contract owner	Management and legal adviser
Employee files	HR, plus the line manager in part	HR only
Financial data	Senior management and accounts	Finance director

Frequently asked questions

Are cloud documents less secure than a local server?

Not necessarily. Security depends on set-up: permissions, two-factor authentication and backups. An unpatched, exposed local server can be more dangerous than a well-configured cloud service.

How do we stop staff photographing documents with their phones?

It can’t be fully prevented technically. The answer is to limit who sees sensitive documents, have staff sign a confidentiality undertaking, make the consequences clear, and use watermarks on highly sensitive documents.

Do we need to encrypt files?

Encrypting laptops and storage media is recommended, as is an encrypted connection to the server or cloud. Encrypting individual files is useful for highly sensitive documents.

What do we do if we discover a document leak?

Cut off access immediately, review the access log to find the source, assess the damage and notify those affected where needed. Check current local legal requirements on reporting.

Do we need a separate backup if files are in the cloud?

Yes, it is advisable. Accidental deletion, a compromised account or ransomware can reach cloud files and their synced copies, so keep an additional, separate copy that isn’t deleted automatically.
