b) Customizing Windows Firewall settings

Customizing Windows Firewall settings is crucial for optimal security. Moreover, it helps prevent unauthorized access.

1. Turning Windows Firewall on or off: Open Windows Security Center and click “Firewall & network protection.” From there, you can enable or disable the firewall for different network types.
2. Creating rules for inbound and outbound connections: Go to “Advanced settings” in the “Firewall & network protection” section. Here, you can create custom rules for specific programs or connections.

c) Using Windows Security Center

Windows Security Center is your go-to hub for managing security features. In short, it’s a user-friendly tool that helps avoid computer repair due to malware infections.

1. Navigating the dashboard: Open Windows Security Center from the Start menu or system tray. The dashboard provides an overview of your computer’s security status.
2. Configuring notifications and alerts: Click the gear icon in Windows Security Center. From there, you can enable or disable notifications for specific security features.

d) Enabling Secure Boot

Secure Boot is a valuable security feature that prevents unauthorized software during boot-up.  

1. Checking if your device supports Secure Boot: Open “System Information” and look for “Secure Boot State” under “System Summary.” If it says “Supported,” your device is compatible.
2. Activating Secure Boot in the UEFI firmware settings: Restart your computer and enter the UEFI firmware settings. Locate the “Secure Boot” option and enable it. Save the changes and exit to apply the new settings.

Best Practices for Enhanced Computer Security

a) Regularly updating Windows 11 and other software

Regular updates are crucial for maintaining your computer’s security. In other words, they help fix vulnerabilities. Ensure that your Windows 11 and other software are up to date.

• Updating Windows 11: Go to “Settings,” then click “Windows Update.” From there, you can check for updates and install them as needed.
• Updating other software: Periodically check for updates on the software you use. Consequently, you’ll ensure that you have the latest security patches.

b)Using strong, unique passwords

Strong, unique passwords are vital for securing your computer and online accounts. By doing so, you minimize the risk of unauthorized access.

• Creating strong passwords: Use a combination of uppercase and lowercase letters, numbers, and symbols. Also, avoid using easily guessable information.
• Using a password manager: A password manager can help generate and store complex passwords. As a result, you’ll enhance your computer’s security.

c) Backing up your data

Regular data backups can save you from potential data loss. In short, they’re a crucial preventive measure against computer repair due to malware infections.

• Using Windows 11 backup features: Go to “Settings” and click “Backup.” Here, you can configure backup settings and choose a storage location.
• Utilizing cloud storage: Cloud storage services provide additional backup options. By doing so, they ensure your data is safe, even in case of hardware failure.

d) Avoiding phishing emails and malicious websites

Phishing emails and malicious websites are common sources of malware.

• Identifying phishing emails: Be wary of suspicious emails and avoid clicking on unfamiliar links. Also, verify the sender’s email address before taking any action.
• Using browser security features: Modern browsers have built-in security features. Therefore, enable them to block malicious websites automatically.

e) Disabling Autorun for external devices

Malware can spread through external devices like USB drives. By disabling Autorun, you reduce the risk of infection.
