Mobile security refers to the protection of smartphones, tablets, and other portable devices from threats such as malware, unauthorized access, and data breaches. It involves implementing measures like strong passwords, encryption, and security software to safeguard personal and sensitive information stored on these devices. As mobile devices often connect to various networks, they can be vulnerable to attacks. Users should be aware of risks associated with public Wi-Fi and should regularly update their operating systems and applications. Employing features like two-factor authentication and remote wipe can further enhance mobile security and protect against potential threats.
