Cyber Security Fundamentals in Bangla

1. VPN (Virtual Private Network): The most effective way to protect yourself while using public WiFi is by connecting to a VPN service. A VPN creates a secure and encrypted connection between your device and the internet, masking your IP address and all data transmitted from view.

2. Use HTTPS: Whenever possible, ensure that websites you visit use HTTPS (Hypertext Transfer Protocol Secure) instead of HTTP. This means that the website supports encryption to protect your data in transit.

3. Update Your Devices: Regularly update your operating system and applications on your devices with the latest security patches to close any potential vulnerabilities before you connect to a public WiFi network.

4. Disable File Sharing: On your laptop or other devices, turn off any file-sharing capabilities that are not needed when you are using public WiFi. This reduces the risk of being targeted by malware or attackers who might try to access files on your device.

5. Use Two-Factor Authentication (2FA): Whenever possible, enable two-factor authentication for your important online accounts. This adds an extra layer of security beyond just a password and username.

6. Avoid Transmitting Sensitive Data: If you don't absolutely need to send sensitive information while connected to public WiFi, wait until you are on a secure network before doing so.

7. Turn Off Automatic Connections: Avoid having your devices automatically connect to WiFi networks, especially when those networks can be easily accessed by others. Only manually join recognized and trusted networks.

8. Use Anti-Virus and Anti-Malware Software: Keep anti-virus and anti-malware software up to date on your devices to protect against known malware.

9. Disable WiFi When Not in Use: If you are not actively using the internet, turn off your device's WiFi connection to minimize the time it is exposed to potential threats.

10. Monitor Your Accounts: Regularly check your bank and email accounts for any unusual activity that might indicate a session hijacking or unauthorized access.

11. Avoid Providing Personal Information on Public WiFi: Engaging in activities that do not require you to enter personal information, such as streaming videos or browsing news sites, is less risky than conducting transactions or logging into accounts with sensitive information.

By following these guidelines and maintaining a healthy level of skepticism about unfamiliar networks, you can significantly reduce the risks associated with using public WiFi. Remember that no method is completely foolproof, so always err on the side of caution.
