Phones & Tablets: How to Stay Safe Online & Offline!

In our modern digital world, smartphones and tablets have become integral parts of daily life, but they also come with security risks. This guide provides essential tips to help you stay safe while using these devices.

1. Keep Your Software Updated

Outdated software is one of the most common ways attackers can exploit vulnerabilities.

• Why it matters: Regular updates fix security vulnerabilities and provide essential patches that protect against new threats.
• What to do:
  • Enable automatic updates for your operating system and apps.
  • Regularly check for system or app updates, especially if you're not using automatic settings.

2. Use Strong Passwords and Biometrics

A weak password can easily be cracked, exposing your personal information.

• What to do:
  • Create a strong password (8+ characters, including letters, numbers, and symbols).
  • Avoid common passwords like “123456” or “password.”
  • Enable biometric authentication like fingerprint or facial recognition for an added layer of security.

3. Enable Two-Factor Authentication (2FA)

Two-factor authentication adds an extra security layer beyond just your password.

• Why it helps: Even if someone gets your password, 2FA ensures they can’t log in without the secondary authentication.
• What to do: Enable 2FA for apps that offer it (such as banking apps, email services, or social media platforms).

4. Be Cautious of Public Wi-Fi

Public Wi-Fi is convenient, but it's often unsecured, making it easier for hackers to access your data.

• What to do:
  • Avoid accessing sensitive information (like online banking) over public Wi-Fi.
  • Use a Virtual Private Network (VPN) to encrypt your internet connection when using public networks.

5. Install Apps from Trusted Sources Only

Apps can harbor malware or spyware if downloaded from unreliable sources.

• What to do:
  • Stick to official app stores (Google Play, Apple App Store).
  • Avoid downloading apps from unknown websites or third-party stores.

6. Review App Permissions

Many apps request access to personal data that they don’t necessarily need to function.

• What to do:
  • Regularly review app permissions on your device.
  • Disable permissions for apps that don’t need them (e.g., camera, microphone, or location).

7. Use a Secure Lock Screen

If your phone or tablet is stolen or lost, a secure lock screen can prevent unauthorized access.

• What to do:
  • Set up a PIN, pattern, or biometric lock.
  • Avoid simple PINs like “0000” or “1234.”

8. Back Up Your Data Regularly

A lost or stolen device doesn’t have to mean losing all your important information.

• What to do:
  • Set up automatic backups to cloud services like Google Drive or iCloud.
  • Regularly check that your backups are working.

9. Avoid Phishing Scams

Phishing attacks trick users into giving away personal information through fraudulent messages.

• What to do:
  • Be cautious of unsolicited emails or texts asking for personal or financial information.
  • Check URLs in emails before clicking on them, and don’t download attachments from unknown senders.

10. Install Antivirus and Security Apps

Although most phones and tablets come with some built-in protection, it doesn’t hurt to add an extra layer of security.

• What to do:
  • Install reputable security apps that offer virus scanning and anti-malware protection.
  • Enable features like “Find My Phone” to locate, lock, or erase a lost or stolen device.

11. Monitor and Limit Screen Time

Not directly related to security, but staying mindful of your device usage can protect you from overexposure to potential threats.

• What to do:
  • Set screen time limits.
  • Take regular breaks to ensure you’re not unknowingly falling victim to threats like phishing or fake ads during long browsing sessions.

Conclusion Staying safe while using your phone or tablet requires a combination of good practices and being aware of potential risks. By following the above steps, you can greatly reduce the chances of falling victim to cyber threats and keep your personal data secure.

12. Be Aware of Bluetooth and NFC Vulnerabilities

While Bluetooth and Near Field Communication (NFC) are useful features, they can also be exploited by cybercriminals to gain unauthorized access to your device.

• What to do:
  • Turn off Bluetooth and NFC when not in use, especially in public places.
  • Make your Bluetooth connection invisible or undiscoverable to avoid unauthorized connections.
  • Avoid accepting file transfers from unknown devices via Bluetooth.

13. Encrypt Your Device

Encryption protects the data on your phone or tablet, ensuring that even if someone gains physical access to your device, they cannot easily read the stored data.

• What to do:
  • Most modern phones and tablets have built-in encryption, which can be enabled via the security settings.
  • iPhones come encrypted by default, but Android users may need to manually enable this feature under "Security" in settings.

14. Be Cautious with Email Attachments and Links

Cyber Criminals often use email to deliver malware or conduct phishing attacks.

• What to do:
  • Don’t open attachments or click on links in emails from unknown or suspicious sources.
  • Always verify the sender’s email address, as phishing scams often use email addresses that are very similar to legitimate ones (e.g., john@company.com could be spoofed as john@compnay.com).
  • Use a trusted email service that has strong anti-spam and phishing filters.

15. Secure Your Cloud Accounts

Many people store sensitive data, like photos, documents, and backups, in cloud services. Securing these accounts is crucial.

• What to do:
  • Use strong, unique passwords for cloud accounts (Google Drive, iCloud, Dropbox, etc.).
  • Enable two-factor authentication for all cloud services.
  • Regularly review the devices that are connected to your cloud account and revoke access to any unfamiliar devices.

16. Protect Yourself from Identity Theft

Your phone or tablet holds a wealth of personal data, from emails to banking information, making it a prime target for identity thieves.

• What to do:
  • Avoid storing sensitive information (like credit card numbers or passwords) directly on your device.
  • Use secure password managers to store passwords.
  • Immediately report to your service provider and relevant authorities if your device is lost or stolen.

17. Use Safe Browsing Practices

The websites you visit can also be a vector for malicious activity, including malware, spyware, or phishing attempts.

• What to do:
  • Only browse trusted websites, particularly when entering personal information.
  • Use browsers that have built-in security features, like Google Chrome or Safari, which warn you if a website is unsafe.
  • Clear your browsing history and cache regularly to protect your personal information.

18. Turn Off Location Tracking When Not Needed

Location tracking is handy for navigation and apps like ridesharing, but constant tracking can expose your location and habits.

• What to do:
  • Disable location services when they are not required.
  • Be selective about which apps have access to your location. Most apps don’t need to know your location to function.
  • Periodically review and clear your location history.

19. Factory Reset Before Selling or Disposing of Devices

Before selling, donating, or recycling your phone or tablet, it’s important to ensure that all personal data is completely erased.

• What to do:
  • Back up any important data you want to keep.
  • Perform a factory reset on the device to wipe all personal information.
  • Remove any linked accounts (Google, Apple ID, etc.) before handing it over.

20. Be Careful with Social Media Apps

Social media platforms collect vast amounts of personal data, and poorly configured privacy settings can expose more information than you intend.

• What to do:
  • Review the privacy settings for each social media app and adjust them to limit what others can see.
  • Be mindful of the personal information you share publicly (birthdate, location, etc.).
  • Avoid using social media logins to access other apps or services, as this can create a broader attack surface for hackers.
