Essential Tips: Safeguarding Your Smartphone – Basic Security and Privacy Practices

Leave a comment

Basic security and privacy practices are essential to ensure the safety of your smartphone and the personal information it contains. Those fundamental steps you can take to enhance the security and privacy of your smartphone:

1. Passcode/Password: Enable a strong passcode or password to unlock your device. Use a combination of numbers, letters, and symbols for added security.

2. Biometric Authentication: If your smartphone supports biometric authentication (such as fingerprint or facial recognition), consider using it in addition to a passcode for added security.

3. Software Updates: Regularly update your smartphone’s operating system and apps. Updates often include security patches that fix vulnerabilities and protect against potential threats.

4. App Permissions: Review the permissions that apps request before installing them. Only grant necessary permissions to apps, and be cautious about granting access to sensitive data like your location, camera, and microphone.

5. App Sources: Download apps only from official app stores (like the Apple App Store or Google Play Store). Third-party app stores can pose a higher risk of downloading malicious apps.

6. Security Software: Consider using reputable mobile security software or antivirus apps to help protect your device from malware and other threats.

7. Lock Screen Notifications: Configure your lock screen settings to hide sensitive content from notifications. This prevents others from seeing your private information without unlocking your device.

8. Encryption: Enable device encryption to secure your data in case your smartphone is lost or stolen. Modern smartphones often come with encryption enabled by default.

9. Remote Tracking and Wiping: Activate the “Find My Device” feature (or equivalent) so you can track your device’s location and remotely wipe its data if it’s lost or stolen.

10. Public Wi-Fi: Avoid using unsecured public Wi-Fi networks for sensitive tasks like online banking or accessing personal accounts. If you must use public Wi-Fi, consider using a virtual private network (VPN) for added security.

11. App Updates: Keep your apps up to date as well. App updates often include security fixes and improvements.

12. Two-Factor Authentication (2FA): Enable 2FA whenever possible for your accounts. This adds an extra layer of security by requiring a second verification step, usually a code sent to your phone.

13. Secure Browsing: Use a secure browser and be cautious when clicking on links in emails, text messages, or websites, as they could lead to phishing attempts or malicious sites.

14. Review Privacy Settings: Regularly review the privacy settings on your smartphone and individual apps. Adjust settings to limit the sharing of your personal information.

15. Data Backup: Regularly back up your smartphone’s data to a secure cloud storage service or your computer to prevent data loss in case of device damage, loss, or theft.

By following these basic security and privacy practices, you can significantly reduce the risk of unauthorized access to your smartphone and personal data.

The most terrifying thing is anyone can be targeted by cybercriminals.

Whether you are just an individual or a company or an organization. No matter what your size is! Here are some cybersecurity basics and putting them in practice will help us protect our business and the risk of a cyber-attack.

Let’s protect our files and devices;

Keep your software up to date whenever new updates are available.

Secure your files by backing up important data offline, on an external hard drive, or in the cloud. Also, ensure the safety of physical paper files.

For enhanced security, password-protect all laptops, tablets, and smartphones. Avoid leaving these devices unattended in public areas.

How we can protect our wireless network?

We can secure our router by doing those primanry steps;

  • By changing the default name and password.
  • Turn off remote management.
  • Log out as the administrator once the route is set up.

Make Smart Security your business as usual

Require strong passwords
  • At least 12 characters.
  • A mix of numbers, symbols, and capital lowercase letters.
  • Never reuse passwords.
  • Don’t share them on the phone, in texts, or by email.
  • Limit the number of unsuccessful log-in attempts to limit password-guessing attacks.
Train all staff

Encourage a secure culture by regularly training employees on security practices. Keep employees informed about new risks and vulnerabilities as they arise. If employees fail to attend these updates, consider restricting their access to the network.

The NIST Cybersecurity Framework

The National Institute of Standards and Technology (NIST) at the U.S. Department of Commerce recommends a framework that helps businesses of all sizes better understand manage, and reduce their cybersecurity risk and protect their network.

There are 5 areas NIST cybersecurity framework suggests. Those are;

Identify
Protect
Detect
Respond
Recover

Identify

Identify starts with making a list of all equipment, software, and data being used, including laptops, smartphones, tablets, and point-of-sales devices.

Create and share a company cybersecurity polity that covers;

Roles and responsibilities for employees, vendors, and anyone else with access to sensitive data.

Steps to take to protect against an attack and limit the damage if one occurs.

Protect

  • Control who logs on to your network and uses
    your computers and other devices.
  • Use security software to protect data.
  • Encrypt sensitive data, at rest and in transit.
  • Conduct regular backups of data.
  • Update security software regularly, automating
    those updates if possible.
  • Have formal policies for safely disposing of
    electronic files and old devices.
  • Train everyone who uses your computers,
    devices, and network about cybersecurity.
    You can help employees understand their
    personal risk in addition to their crucial role
    in the workplace.

Detect

Monitor your computers for unauthorized personnel access, devices (like USB drives), and software.

Check your network for unauthorized users or connections.

Investigate any unusual activities on your network or by your staff.

Respond

Notifying customers, employees, and others whose data may be at risk.

Keeping business operations up and running.

Reporting the attack to law enforcement and other authorities.

Investigating and containing an attack.

Updating your cybersecurity policy and plan with lessons learned.

Preparing for inadvertent events (like weather emergencies) that may put data at risk.

Recover

Repair and restore the equipment and parts of your network that were affected.

Keep employees and customers informed of your response and recovery activities.
