The concept of the “human firewall” emphasizes the importance of individual awareness and skepticism in cybersecurity. It involves being cautious about sharing personal information online, discerning the trustworthiness of websites and links, and understanding what personal details are most vulnerable. Strong password protection, vigilance against fake Wi-Fi connections, and safe use of public networks, ideally with a VPN, are key practices. This approach underlines personal responsibility in safeguarding against cyber threats by questioning and verifying before trusting digital interactions.
