Why Security Matters

Risks of Unsecure Sharing

If you share files without good security, your information is not safe. There are many dangers that can hurt your files or your group. Look at this table to see some common security threats you might face when sharing files on cloud platforms like OneDrive:

You could also have problems like sharing private folders by mistake, ransomware attacks, or syncing files to devices that are not protected. Sometimes, workers share files by accident or use apps that do not keep files safe. These problems can cause data leaks, make people lose trust, or even get your business in legal trouble.

Tip: Always check who can see your files before sharing. Use strong passwords and do not use public links.

Benefits of Secure Sharing

When you use secure sharing in OneDrive, your files are safer and your team can work better. Secure sharing lets you pick who can see or change your files. You can set passwords, make links expire, and stop downloads to keep your data safe. OneDrive encrypts your files when you upload them and when they are stored, so your info stays private.

Secure sharing also helps your group follow rules like GDPR and HIPAA. You can use tools like Data Loss Prevention and audit logs to see who looks at your files and stop leaks. These tools help you show that you follow data protection laws.

Groups that use secure sharing in OneDrive say they get more done. You and your team can find files faster, do not need to send many emails, and work together safely from anywhere. Secure sharing keeps your work safe and helps everyone stay organized and work well.

How to Share Files

Sharing files in OneDrive helps you work with others while keeping your information safe. You can use both the web and desktop apps to share files or folders. Follow these steps to make sure you share files securely.

Select Files or Folders

Start by choosing what you want to share. You can pick a single file, many files, or a whole folder. On the web, sign in to OneDrive and find your files. On the desktop app, open your OneDrive folder on your computer.

Steps to select files or folders:

1. Open OneDrive on the web or your computer.

2. Find the file or folder you want to share.

3. Click once to select it. For more than one, hold the Ctrl key and click each item.

Tip: Only share files with people who need them. Avoid sharing with "everyone" or making files public. This keeps your data safer.

Set Permissions

After you select your files, you need to set permissions. Permissions control what others can do with your files. You can let people view, edit, or comment.

Common permission levels:

To set permissions:

1. Click the Share button.

2. In the sharing window, look for link settings or a gear icon.

3. Choose if people can view or edit. Uncheck "Allow editing" to make it view-only.

4. For extra safety, turn on "Block download" so others cannot save a copy.

Note: Giving edit rights lets others change your files. Use view-only if you do not want changes.

Choose Recipients

You decide who gets access to your files. You can share files with specific people by entering their email addresses. This is safer than sharing with a link that anyone can use.

How to choose recipients:

1. In the Share window, select "Specific people."

2. Enter the email addresses of the people you trust.

3. Add a message if you want to explain what you are sharing.

You can also share files with groups or people in your organization. If you need to share with someone outside your group, check your settings first. Some organizations block sharing with people outside the company.

Alert: If you share a folder link, people can forward it. Always check who has access and remove people who no longer need it.

Send Secure Links

When you finish setting permissions and choosing recipients, you can send the link. OneDrive lets you copy the link or send it by email. Before you send, review the link settings.

Steps to send secure links:

1. Click "Apply" after setting permissions.

2. Copy the link or use the "Send" button to email it.

3. For more security, set an expiration date for the link. This makes the link stop working after a certain time.

4. If you want, add a password for the link (only for "Anyone" links).

You can also block downloads for view-only links. This stops others from saving or printing your files. If you need to stop sharing later, go to the file in OneDrive, open the details pane, and remove access or delete the link.

Tip: Review your shared files often. Remove access for people who no longer need it. This keeps your files safe.

By following these steps, you can share files in OneDrive without risking security. Always check your settings before you share files, and use the tools OneDrive gives you to control access.

Advanced Security

Expiration Dates

You can make shared links in OneDrive expire. This means people can only use the link for a set time. After that, the link will not work anymore. This helps stop people from using old links to get your files.

Tip: Always use expiration dates for shared links, especially with people outside your group.

Password Protection

You can put a password on your shared links in OneDrive. This makes your files safer. Only people with the password can open the link. Make your password strong by using 12 to 14 characters. Use big and small letters, numbers, and symbols. You can also use a passphrase, which is easier to remember.

1. Turn on password protection when you share files or folders.

2. Make a strong password with different kinds of characters.

3. Give the password to your friends in a safe way.

Note: Never send the password in the same message as the link.

Block Download

OneDrive lets you stop downloads for shared files. When you use this, people can only look at the file online. They cannot save, print, or copy the file to their computer. This keeps your private files safer.

• Blocking downloads lets people only view the file.

• It helps stop others from sharing your files without asking you.

• OneDrive blocks downloads for Office files, audio files, some pictures, and some PDFs.

Alert: Use block download if you want to share files but do not want others to keep them.

Revoke Access

You can stop people from seeing your shared files any time. If you do not want someone to see your files, you can take away their access. You can do this on the OneDrive website or with admin tools.

1. Go to the file or folder in OneDrive.

2. Open the sharing settings.

3. Remove the person or delete the link to stop sharing.

4. Admins can use special tools to manage access for many people.

Tip: Check your shared files often. Take away access from people who do not need it anymore.

Extra Protection Features

Personal Vault

You can use OneDrive Personal Vault to keep your most sensitive files extra safe. Personal Vault is a special locked spot inside your OneDrive. It gives you more protection than normal folders.

• Personal Vault needs two-factor authentication, like a code sent to your phone or a fingerprint scan.

• The vault locks itself if you stop using it for a short time.

• Files in Personal Vault are encrypted on your device with BitLocker (on Windows 10 PCs).

• You cannot share files straight from Personal Vault, which helps stop mistakes.

• Files are never left unprotected or saved on your device or browser.

• You can scan papers right into the vault from your phone for quick, safe storage.

Tip: Use Personal Vault for things like passports, tax records, or medical files. This keeps them safe from people who should not see them.

File Request Folders

You can collect files from others safely using file request folders in OneDrive. This feature lets people upload files to a folder you pick, even if they do not have a OneDrive account.

When you set up a file request:

• People can only upload files. They cannot see, edit, or delete anything in the folder.

• Uploaders cannot see other files or know who else has uploaded.

• You control the link and can turn it off anytime to stop uploads.

• You see who uploaded each file, which helps you stay organized.

Note:

Encryption

OneDrive protects your files with strong encryption both when you upload them and when they are stored.

• Data moving between devices uses SSL/TLS with 2048-bit keys to keep your files safe.

• Data that stays in OneDrive is protected with BitLocker and per-file encryption using AES 256-bit keys.

• Each file gets its own encryption key, and these keys are kept separate from your files.

• OneDrive’s encryption meets FIPS 140-2 standards, which are trusted by banks and governments.

Best Practices

Review Shared Files

You need to check your shared files often to keep them safe. First, see who can look at or change your files. Go to the "Manage Access" page in OneDrive. There, you will find a list of people and groups who have access. Take away access from anyone who does not need it anymore. If someone outside your group needs access, add them as a guest user in Azure Active Directory. This helps you control what they can do.

Here are some easy steps to help you review shared files:

1. Make rules for sharing with your Security or Compliance team.

2. Use Data Loss Prevention (DLP) to keep private info safe.

3. Create security groups to control sharing outside your group.

4. Choose default link types and permissions that limit file access.

5. Set expiration dates on links so access ends after a while.

6. Teach users about safe sharing with messages and training.

7. Watch sharing activity using audit logs and reports.

8. Manage guest users to keep outside access safe.

Tip:

Educate Recipients

You help keep files safe when you teach others how to use them. Tell people the difference between "View Only" and "Can Edit" permissions. Remind them to use links instead of sending files as attachments. This helps you control who sees the newest version.

You can also ask people to use BitLocker encryption on their devices. Tell them to turn on file versioning. Remind them to watch for alerts about strange activity.

Monitor Activity

You need to watch what happens to your shared files. OneDrive gives you tools to do this. Use the "Shared by You" report to see what you have shared. The "Shared with You" report shows what others have shared with you. The "Manage Access" page lets you check who has access and what they can do.

If you are an admin, use the Microsoft 365 admin center to see user activity reports. These reports show who looked at, changed, or synced files. You can also use other tools for more reports and alerts about strange activity, like someone making many anonymous links.

Alert: Set up alerts for odd sharing or access. This helps you find problems early and keep your files safe.

---

You can keep your files safe in OneDrive if you follow some simple steps:

1. Make sure you set who can see your files and check these settings every three months.

2. Pick strong passwords and turn on two-factor authentication for more safety.

3. Watch who you share with and delete links you do not use anymore.
