6.5.1 Hardware Methods
Biometric Authentication:
Many modern devices come equipped with biometric sensors, such as fingerprint scanners or facial recognition cameras. These hardware components provide an extra layer of security by ensuring that only authorized users can access the device.
Secure Boot:
Secure boot is a hardware- based process that ensures only trusted software is loaded during the device startup. It prevents malware from infecting the boot process.
Firewalls:
A firewall is a security system that helps protect computers and networks from unauthorized access. It acts like a barrier, blocking unwanted traffic from entering or leaving a network while allowing safe, approved traffic to pass through. Firewalls help keep personal and sensitive information secure by filtering out potential threats, such as hackers or malware, before they can reach your device or network.
