What are the security risks of loT device ?

security risks of IoT (Internet of Things) devices --- ⚠️ Security Risks of IoT Devices The Internet of Things (IoT) has transformed our lives, connecting everything from smart thermostats to wearable health monitors. However, with this convenience comes a significant downside: security risks. Below are some of the most critical concerns: 1. **Weak or Default Passwords** Many IoT devices come with default usernames and passwords (like “admin/admin”), which users often don’t change. Hackers can easily guess these credentials and gain access. 2. **Lack of Regular Updates** IoT manufacturers sometimes neglect to issue regular firmware or security updates. This leaves devices vulnerable to known exploits. 3. **Unencrypted Communication** If a device transmits data without encryption, attackers can intercept sensitive information, such as location, passwords, or personal habits. 4. **Botnet Attacks (e.g., Mirai)** Compromised IoT devices can be t...

Which phone has the best biometric security?

*Best Biometric Security Phones* When it comes to biometric security, several phones stand out for their advanced features and reliability. Here's a breakdown of some top options: *Top Contenders* - *Samsung Galaxy S24 Ultra*: Features an ultrasonic fingerprint sensor that creates a 3D image of your fingerprint, making it more secure and accurate than traditional capacitive fingerprint readers. It also offers facial recognition, although it's not as secure as the fingerprint sensor. - *Apple iPhone 16 Pro Max*: Boasts Face ID, a facial recognition system that uses a TrueDepth camera to project over 30,000 invisible dots, creating a precise depth map of your face. This makes it difficult for hackers to access your device using photos or masks. - *Google Pixel 8*: Offers facial recognition and fingerprint scanning, with the latter being more secure. The Pixel 8's biometric system is securely stored in the phone's Tensor M2 processor. *Biometric Security Features to Consider* - *Ultrasonic Fingerprint Sensors*: More secure than traditional capacitive sensors, as they create a 3D image of your fingerprint. - *Facial Recognition*: Convenient, but may be less secure than fingerprint scanning, especially if it doesn't use 3D mapping. - *Encryption*: Ensures that your biometric data is protected from unauthorized access. *Most Secure Phones* - *Purism Librem 5*: Known for its hardware kill switches that physically disconnect the camera, microphone, and other sensors, providing maximum security and control. - *Bittium Tough Mobile 2C*: Features certified security for confidential level protection, dual-boot capability, and hardware-based security. - Blackphone Privy 2.0: Offers a customized version of Android with restricted app permissions, sandboxing, and secure boot.¹ ²
