Internet 09 Zasady bezpieczeństwa w sieci

Introduction

The purpose of this tutorial is to provide essential guidelines for enhancing your online safety. The internet poses various risks, including data theft, fraud, and system breaches. By following these practices, you can significantly reduce your vulnerability and protect your personal information.

Step 1: Use Strong Passwords

• Create complex passwords that are difficult to guess.
• Combine upper and lower case letters, numbers, and special characters.
• Avoid using easily accessible information such as birthdays or names.
• Change your passwords regularly and use unique passwords for different accounts.

Step 2: Enable Two-Factor Authentication

• Activate two-factor authentication (2FA) for your online accounts.
• This adds an extra layer of security by requiring a second form of verification (e.g., a text message or authentication app).
• Regularly review account security settings to ensure 2FA is enabled where possible.

Step 3: Be Wary of Phishing Scams

• Always verify the sender’s email address before clicking on links or downloading attachments.
• Look out for suspicious emails that create a sense of urgency or request personal information.
• Hover over links to see the actual URL before clicking.

Step 4: Keep Software Updated

• Regularly update your operating system, browsers, and software applications.
• Enable automatic updates to ensure you receive the latest security patches.
• Use reputable antivirus software to protect against malware and perform regular scans.

Step 5: Secure Your Wi-Fi Network

• Change the default username and password for your router.
• Use WPA3 encryption for your Wi-Fi network for better security.
• Disable guest networks unless needed and monitor connected devices.

Step 6: Be Cautious with Personal Information

• Limit the amount of personal information shared on social media.
• Review privacy settings on platforms to control who can see your information.
• Think twice before sharing sensitive details publicly or in online forums.

Conclusion

By implementing these safety principles, you can significantly improve your online security and reduce the risk of data breaches and fraud. Start by assessing your current security practices and make adjustments where necessary. Stay informed about new threats and continue to educate yourself on best practices for internet safety.
