Mobile security is a specialized discipline within cybersecurity that focuses on protecting portable computing devices, such as smartphones, tablets, and wearables, from threats and vulnerabilities. It addresses the unique risks associated with mobile technology, including malware distributed through app stores, insecure Wi-Fi connections, phishing attacks targeting mobile users, device theft, and data leakage from applications. The field encompasses a range of protective measures, from securing the device's operating system and hardware to implementing mobile device management (MDM) policies, data encryption, and secure application development practices to safeguard both personal and corporate information in an increasingly connected and mobile environment.
