Why AI Safety Matters
AI systems can process large amounts of information and automate many tasks. This makes them useful, but it also means users need to think carefully about the information they provide and the actions they allow AI systems to perform.
Privacy, security, accuracy, and human oversight are important parts of responsible AI use. Security organizations and standards bodies increasingly emphasize risk management, access controls, monitoring, and the protection of sensitive information when AI is adopted.
The good news is that many AI safety practices are simple. A few careful decisions can significantly reduce unnecessary risk.
1. Do Not Share Sensitive Personal Information
One of the most important AI safety rules is simple: do not enter sensitive personal information unless you fully understand why it is required and how the information will be handled.
Examples of sensitive information include:
- Passwords
- Bank account details
- Credit or debit card numbers
- Government identification numbers
- Private medical information
- Private addresses or confidential personal records
If you are using AI to improve a document, replace private information with placeholders before uploading it.
For example, instead of entering a real customer’s name, address, and account number, use:
- [Customer Name]
- [Address]
- [Account Number]
2. Never Paste Passwords or Security Codes
Never enter your password, one-time verification code, recovery code, private API key, or other authentication secret into an AI chatbot.
AI tools can help you understand security concepts, generate example code, or explain how authentication works. However, real secrets should remain private.
If you need help fixing code that contains a secret, remove the secret before sharing the code.
Bad Example
My API key is ABC123… Please fix my application.
Better Example
My application uses an API key stored in an environment variable. I am receiving an authentication error. Can you help me debug the problem?
3. Check Before Sharing Business Data
Employees and business owners should be especially careful when using AI at work.
Confidential company information may include:
- Customer data
- Financial reports
- Internal business strategies
- Private source code
- Employee information
- Unreleased product plans
Before uploading company data to an AI service, check your organization’s policies and confirm that the tool is approved for that type of information.
This is particularly important when employees use unapproved AI tools without the knowledge of their employer. This practice is often described as Shadow AI.

4. Review AI Privacy Settings
Before regularly using an AI service, spend a few minutes reviewing its account and privacy settings.
Look for options related to:
- Conversation history
- Data retention
- Model training preferences
- Connected applications
- Account permissions
Privacy options can differ between AI services and may change over time. Review settings periodically instead of assuming that your preferences will always remain the same.
5. Use Strong Account Security
Your AI account may contain conversations, uploaded files, connected services, and other useful information. Protect the account as carefully as you would other important online accounts.
Good account security practices include:
- Use a strong and unique password.
- Enable multi-factor authentication when available.
- Do not share your account with other people.
- Review active sessions and connected devices.
- Remove applications that no longer need access.
A secure AI tool is less useful if the account itself is poorly protected.
6. Verify Important AI Answers
AI can generate useful answers quickly, but it can also make mistakes, misunderstand questions, or provide outdated or inaccurate information.
Always verify important information before using it for:
- Medical decisions
- Legal matters
- Financial decisions
- Business reports
- Academic research
- Security decisions
Use AI as a helpful assistant, not as the final authority on high-impact decisions.
A Simple Verification Process
- Ask AI for an explanation.
- Check the important claims.
- Compare the information with reliable sources.
- Correct mistakes before publishing or acting.
7. Be Careful When Uploading Files
AI tools can analyze documents, spreadsheets, images, presentations, and other files. Before uploading a file, check whether it contains information that should remain private.
Ask yourself:
- Does this file contain personal information?
- Does it contain customer data?
- Is the information confidential?
- Do I have permission to upload it?
- Can I remove sensitive information first?
When possible, upload a smaller or anonymized version of the file instead of the complete original document.
8. Give AI Only the Access It Needs
Modern AI tools can connect with email accounts, cloud storage, calendars, documents, and other applications.
These integrations can be useful, but unnecessary permissions can create additional risk.
Follow the principle of least privilege:
Give an AI application only the minimum access required to perform the task.
For example, if an AI tool only needs access to one folder, do not automatically give it access to your entire cloud storage account.
9. Watch Out for AI Scams and Fake Content
AI can make scams, fake images, phishing messages, and misleading content more convincing.
Be cautious when you receive:
- Unexpected requests for money
- Urgent messages demanding immediate action
- Suspicious voice or video messages
- Links asking for login information
- Messages pretending to come from a company or family member
Do not assume that a realistic-looking image, voice, or message is automatically genuine.
When something is important or unusual, verify it through another trusted communication method.
10. Keep a Human in Control
AI can automate tasks, but important decisions should still receive appropriate human review.
This is especially important when AI can:
- Send emails automatically
- Access business systems
- Make purchases
- Change important files
- Access sensitive information
- Perform actions on behalf of a user
Before allowing an AI agent or automation system to perform important actions, clearly define its permissions, limits, and approval requirements.
