The main parts of Microsoft Information Protection work together to keep your data safe. Here is a quick look at what each part does:

Benefits

Using Microsoft Information Protection makes your data safer and your work easier. You can:

1. Keep private information safe from people who should not see it.

2. Follow rules for laws like GDPR and HIPAA.

3. Use automatic sorting and labeling to avoid mistakes.

4. Decide who can see, change, or share files, even outside your company.

5. Watch and check data use to find risks early.

You get better control over your data at work or at home. The system helps you follow rules and avoid big problems. You also save time because things like labeling and encryption happen by themselves.

Assess Needs

Identify Sensitive Data

First, you need to find out what sensitive data your company has. Sensitive data means private or important information. Here are some examples:

• Personal details like names, addresses, and social security numbers

• Financial information such as payment cards and bank accounts

• Medical records and health information

• Employee data, including contracts and tax IDs

• Intellectual property, trade secrets, and product details

• Operational documents and inventory lists

• Industry-specific data, like customer needs or marketing plans

You should check every place where your data is stored. This includes emails, documents, databases, and cloud storage. Make a list of all the types of sensitive data you find. This helps you know what you need to protect.

Tip: Many companies make mistakes when finding sensitive data. You can stop these mistakes by splitting up sensitive data, limiting who can see it, and writing down your rules. Always check who else can see your data, like vendors, before you share it.

Define Protection Goals

After you find your sensitive data, you need to set clear goals for keeping it safe. These goals help you choose how to protect your data and meet your business needs. You can use systems like internal classification or Microsoft Purview to sort your data into groups. For example, you might use labels like Personal, Public, Confidential, or Highly Confidential.

Each label should have rules for who can see the data and what they can do with it. Highly confidential data may need encryption and strong access controls. Less sensitive data may only need simple protections.

You should match your protection goals with your business goals. Work with leaders from IT, security, and business teams to set clear results. You want to keep data safe but also easy to use. Check your goals often and get feedback to make changes as your business grows.

Note: Give people clear jobs for protecting data. Make sure everyone knows what to do. Use surveys and reports to see if your protection goals work for your business.

Classify with Sensitivity Labels

Sensitivity labels help you sort and protect data. You use them to mark files, emails, meetings, and groups. Labels show people how to handle information. When you set up labels, it is easier for everyone to follow rules.

Create Labels

First, pick categories that fit your business. Most companies use labels like Public, Internal, Confidential, and Highly Confidential. You can add sub-labels for more details, like Confidential – PII or Confidential – Executive Team. This helps people choose the right label for each case.

Here are steps to make good sensitivity labels:

1. Look at your data classification policy and pick clear levels.

2. Decide where each label should be used—files, emails, meetings, groups, or sites.

3. Choose protection options, like encryption or watermarks, for each label.

4. Set up auto-labeling so the system tags files and emails by their content.

5. Add sub-labels to give more details and help users pick correctly.

6. Keep the number of main labels and sub-labels small. Most companies use five main labels and five sub-labels.

Tip: Ask users to say why they lower or remove a label. This helps you keep track and makes people responsible.

Publish and Set Defaults

After you make your labels, publish them so people can use them. You can set a default label for files, emails, or meetings. For example, you might set "Confidential" as the default for new documents. This makes sure every file gets a label, even if someone forgets.

Many companies use automated rules to set default labels. You can use tools like Microsoft Purview to make these rules. Automation helps stop mistakes and keeps data safe. For meetings, you can set a default label so every invite gets protection, like encryption or watermarking.

Note: Watch how people use labels. Use reports to find mistakes and make your label settings better over time.

Set Up DLP Policies

Data loss prevention (DLP) policies help stop sensitive data from leaving your company by mistake. You use DLP to protect data in emails, files, chats, and cloud storage. DLP works with people, processes, and technology to keep information safe.

Configure DLP Rules

You begin by making DLP rules that fit your company’s needs. Make different rules for sharing inside and outside the company. This helps you control how data moves. You can use notifications and policy tips to warn users about risks when they try to share sensitive data. Blocking actions stop leaks before they happen. But you should let users override blocks if they give a reason. This helps you track and improve your rules.

Follow these steps to set up DLP rules:

1. Make separate policies for sharing inside and outside your company.

2. Turn on user notifications and policy tips to help users.

3. Set up blocking, but let users override if they give a reason for checking later.

4. Teach users before you start strict blocking.

5. Use simulation mode first to test rules and lower false alerts.

6. Check audit logs to see what users do and change rules if needed.

Tip: Block data in steps. This helps users get used to new rules and keeps them from getting upset.

Prevent Data Leakage

DLP policies help stop people from sharing private data by accident. For example, a big bank used DLP to keep personally identifiable information (PII) from leaving in email or Teams. DLP uses AI to check content against your rules, sorts sensitive data, and adds encryption.

Real-world examples show how DLP works:

• DLP finds and blocks sharing of trade secrets, financial data, and intellectual property.

• Policy tips teach users and help stop mistakes before they happen.

• DLP helps you follow laws like GDPR and HIPAA by keeping sensitive data safe.

• Reports and alerts let you watch for problems and make your rules better.

• Training users helps them learn and lowers leaks.

Keep training users and making clear rules. This makes DLP work better. You protect your company’s good name and avoid big mistakes.

Deploy Scanner for On-Premises Data

Discover Sensitive Files

You must find sensitive files on your company’s servers. Use the Microsoft Purview Information Protection On-Premises Scanner for this job. The scanner connects to places like SharePoint Server, NAS, or Windows File Servers. Install the scanner on a Windows Server that can reach Microsoft 365 online. This setup lets you scan files and take action.

Here are steps to find sensitive files:

1. Link your cloud apps to Microsoft Defender for Cloud Apps. Use app connectors or conditional access app control to scan and check policies.

2. Go to the Defender portal to see which files people share. You can also see who can open them and their status.

3. Set up sensitive information types and labels in Microsoft Purview. These labels work with Defender for Cloud Apps.

4. Turn on automatic scanning for new files. The scanner looks for sensitivity labels and warns you if it finds risky content.

5. Make file policies to scan content in cloud apps. The scanner uses Microsoft Purview Information Protection to spot sensitive data almost right away.

Tip: Run your first scan in report mode. This lets you see what the scanner finds before you add labels or make changes.

Apply Labels and Protection

Once you find sensitive files, you must protect them. The scanner can add labels like "confidential" or "highly confidential" based on your rules. These labels stay with the files, even if someone shares or edits them.

• Automated scanning and sorting help you find sensitive data quickly.

• Sensitivity labels are added automatically, so you do not need to label each file yourself.

• Data Loss Prevention (DLP) policies stop people from sharing or deleting files without permission.

• Microsoft Defender for Cloud Apps finds cloud apps that use your data and adds protection.

• Microsoft Intune checks if devices follow your security rules before letting them open sensitive files.

• The Microsoft 365 Compliance Center helps you manage and watch all your policies in one place.

• Retention labels help you keep data only as long as needed for compliance.

Note: All actions and findings are saved in the Microsoft 365 Unified Audit Log. You can look at these logs to track changes and make your data protection plan better.

Train Users

Communicate Policies

You need to make sure everyone understands your data protection rules. Start by using clear and simple labels for your files and emails. When you use easy-to-understand categories, people can quickly choose the right label. Run education campaigns to help your team learn about sensitivity labels and why they matter. You can add tooltips and prompts inside Office apps. These reminders guide users to follow the right steps when they work with sensitive data.

Tip: Work with your legal, HR, and IT teams. This teamwork helps you answer questions and support everyone as they learn new rules.

Keep your training ongoing. Offer short lessons or reminders to help users remember the difference between labels like "Confidential" and "Internal." Use Microsoft tools to show real examples and let users practice labeling files. When you keep the message simple and repeat it often, your team will remember what to do.

Drive Adoption

You want your team to use protection tools every day. Set clear goals for adoption, such as the number of users who finish training or use labels in their work. Track how many people use the tools each day and each month. Watch how long users spend with the protection features. This helps you see if they understand and use the tools well.

• Check onboarding completion rates to see who finishes training.

• Look at how often users return to use the tools.

• Use surveys to ask users what works and what needs to improve.

• Segment your data by department or region. This helps you find teams that need more help.

• Support champions in each team. These users can help others and share tips.

Note: Always protect user privacy. Use only group data and never judge individual performance with these numbers.

When you focus on training and support, your team will feel confident. They will use the protection tools the right way, keeping your company’s data safe.

Apply Permissions and Monitor

Control Access

You must set strong permissions to keep data safe. First, find where your important files are stored. Check places like OneDrive, SharePoint, and Teams. Only give access to people who need it for work. This is called least privilege. Use the Microsoft 365 Admin Center to make special roles. Give these roles to certain sites, channels, or libraries.

• Match job roles with the right permissions.

• Use sensitivity labels in Microsoft Purview to sort and protect files.

• Give short-term access when needed.

• Check permissions often with built-in audit tools.

• Remove access quickly if someone leaves or changes jobs.

• Use access controls with Conditional Access policies for more safety.

• Use Data Loss Prevention (DLP) to stop risky sharing.

• Set up controlled folder access to block unwanted changes.

Tip: Always tell users when permissions change. This helps everyone know why you protect some files.

Review and Optimize

You need to keep checking your protection settings. Regular checks help you find problems early. Use automatic tools to see who can view or change sensitive data. Set alerts for strange actions or broken rules. Microsoft Purview and Defender tools help you watch data use as it happens.

1. Check access rights every month. Remove old or extra permissions.

2. Use reports to see how people use sensitivity labels.

3. Change your policies when new threats or rules come up.

4. Train your team often. Remind them about good habits.

5. Test your incident response plan. Make sure you can act fast if something goes wrong.

6. Run audits to check if data is labeled and protected the right way.

Note: Watching all the time helps you find risks early. You can fix problems fast and follow the law.
