Privacy vs Security: What's the Difference?
Security is primarily about protecting systems and information from unauthorized access, alteration, destruction or disruption.
Privacy is about how information about you is collected, processed, stored and shared.
For example, using a strong password improves account security. Limiting unnecessary app permissions can improve privacy.
You should think about both.
1. Use Strong and Unique Passwords
One of the easiest ways to improve account security is to use a different strong password for every important account.
Avoid using:
- Your name
- Date of birth
- Phone number
- Simple sequences
- Common words
- The same password everywhere
A long, unique password or passphrase is generally much better than a short predictable password.
2. Use a Password Manager
Remembering dozens of unique passwords can be difficult. A reputable password manager can generate and store passwords so you don't have to memorize every one.
A password manager can help you:
- Create strong passwords
- Store unique credentials
- Reduce password reuse
- Identify weak passwords
- Save time when logging in
Protect your password-manager account with a strong master password and appropriate multi-factor authentication.
3. Enable Multi-Factor Authentication
Multi-factor authentication (MFA) adds an additional verification step beyond your password.
Depending on the service, this could involve:
- Authenticator applications
- Security keys
- Passkeys
- SMS codes
- Biometric verification
Where available, stronger phishing-resistant methods such as passkeys or security keys can provide significant protection.
4. Keep Your Software Updated
Operating systems, browsers, applications and devices receive security updates that can fix vulnerabilities.
Enable automatic updates when appropriate and regularly check devices that don't update automatically.
Don't ignore security updates simply because an application appears to work normally.
5. Learn to Recognize Phishing
Phishing is a social-engineering technique designed to trick people into revealing information, installing malicious software or performing an unwanted action.
Warning signs can include:
- Unexpected urgent messages
- Requests for passwords
- Requests for verification codes
- Suspicious attachments
- Unusual payment requests
- Misspelled or suspicious domains
- Messages asking you to bypass normal procedures
When in doubt, visit the organization's official website directly instead of clicking the message's link.
6. Be Careful With Unknown Links
Don't click links simply because they arrive through email, SMS, social media or messaging applications.
Before opening a link, consider:
- Who sent it?
- Were you expecting it?
- Does the domain look correct?
- Is it asking for sensitive information?
- Does the message create unnecessary urgency?
7. Review App Permissions
Apps may request access to your camera, microphone, location, contacts, files or other device features.
Review permissions periodically and remove access that an application doesn't genuinely need.
On Android and other modern operating systems, permission controls can help you limit unnecessary access.
8. Secure Your Wi-Fi
Your home router is an important part of your digital security.
Recommended practices include:
- Change default administrator credentials
- Use modern Wi-Fi security
- Use a strong Wi-Fi password
- Update router firmware
- Disable unnecessary features
- Review connected devices
9. Be Careful on Public Wi-Fi
Public Wi-Fi can be convenient, but you should avoid assuming that every network is trustworthy.
When using public networks:
- Prefer HTTPS websites
- Avoid sensitive transactions on questionable networks
- Disable automatic connection to unknown networks
- Keep your operating system updated
- Use appropriate security controls
10. Understand VPNs
A VPN can encrypt traffic between your device and a VPN endpoint, depending on how the service is configured.
VPNs can be useful for certain privacy and remote-access scenarios, but a VPN doesn't make you anonymous or protect you from every type of online threat.
A VPN should be considered one layer of security rather than a complete security solution.
11. Improve Browser Privacy
Your browser is one of the most frequently used applications on your device.
Good practices include:
- Keep your browser updated
- Remove extensions you don't need
- Review website permissions
- Use secure connections
- Review privacy settings
- Avoid installing unknown extensions
12. Manage Cookies and Tracking
Cookies can be useful for website functionality, but some are also used for analytics, personalization and advertising.
Review your browser's privacy settings and website cookie controls to decide which tracking you are comfortable with.
13. Protect Your Social Media Accounts
Social media accounts can contain personal information that attackers may use for social engineering.
Protect them by:
- Using unique passwords
- Enabling MFA
- Reviewing active sessions
- Checking connected applications
- Limiting unnecessary personal information
- Reviewing privacy settings
14. Secure Your Email Account
Your primary email account is especially important because it may be used to reset passwords for other services.
Protect it with:
- A unique strong password
- MFA or a passkey where available
- Recovery options
- Security alerts
- Regular session reviews
15. Protect Online Banking
Use only official banking applications and websites when accessing financial services.
Never provide banking credentials or one-time authentication codes to someone who contacts you unexpectedly.
Enable transaction notifications where available and report suspicious activity to your financial institution immediately.
16. Download Software Carefully
Download applications from official sources whenever possible.
Be particularly careful with:
- Cracked software
- Modified applications
- Unknown APK files
- Random browser extensions
- Unverified installers
- Suspicious download websites
Free software isn't automatically safe, and paid software isn't automatically safe either. Verify the source.
17. Maintain Backups
Backups can protect you against hardware failure, accidental deletion, ransomware and other incidents.
Important files should be backed up using a strategy appropriate for their importance.
Consider maintaining more than one copy and periodically verifying that backups can actually be restored.
18. Understand Encryption
Encryption protects information by transforming it into a form that requires the appropriate key or mechanism to access.
You may encounter encryption in:
- HTTPS
- Encrypted messaging
- VPN connections
- Encrypted storage
- Cloud services
Encryption is an important security technology, but it doesn't eliminate all risks.
19. Protect Your Cloud Accounts
Cloud services often contain valuable documents, photos and other personal information.
Protect them with:
- Strong unique passwords
- MFA
- Security alerts
- Regular session reviews
- Careful sharing settings
Check who has access to shared files and folders.
20. Secure Your Devices
Protect your computers and smartphones with basic security controls.
- Use a screen lock
- Keep software updated
- Install applications carefully
- Enable device encryption where available
- Review installed applications
- Use security software where appropriate
21. Check for Data Breaches
Your email address or other information may appear in a data breach involving an online service.
Use reputable breach-notification services to monitor exposed accounts and change passwords immediately when necessary.
If a password was reused across multiple websites, change it everywhere it was used.
22. Reduce Unnecessary Permissions
Review permissions on your smartphone, browser and applications.
Ask yourself:
- Does this app really need my location?
- Does it need microphone access?
- Does it need my contacts?
- Does it need access to my photos?
- Does it need access all the time?
Grant only the access necessary for the service to function.
23. Think Before Sharing Personal Information
Information posted publicly can sometimes be combined with other information to create a detailed profile.
Avoid unnecessarily sharing:
- Home address
- Personal phone numbers
- Travel plans
- Identification documents
- Financial information
- Private account details
Think carefully before posting information publicly.
24. Learn Common Online Scams
Cybersecurity isn't only about technical attacks. Many attacks rely on human psychology.
Common scams include:
- Fake job offers
- Investment scams
- Fake technical-support messages
- Delivery scams
- Fake account-verification messages
- Romance scams
- Impersonation scams
- Fake giveaways
If someone unexpectedly asks for money, passwords or authentication codes, stop and independently verify their identity.
25. Create a Personal Security Plan
The best security strategy is one you can maintain consistently.
Create a simple personal security routine:
- Review important accounts.
- Enable MFA.
- Update devices.
- Check account sessions.
- Review app permissions.
- Check backups.
- Remove unused applications.
- Review privacy settings.
What Should You Secure First?
If you have limited time, prioritize your most important accounts.
| Priority | Account / Device | Action |
|---|---|---|
| 1 | Primary Email | Unique password + MFA |
| 2 | Banking / Financial | Official apps + alerts + MFA where available |
| 3 | Password Manager | Strong master password + MFA |
| 4 | Cloud Storage | MFA + review sharing |
| 5 | Social Media | MFA + privacy review |
