</aside>

Types of Door Locks
- Traditional Padlocks
- Easily defeated and offer minimal protection
- Basic Door Locks
- Vulnerable to simple techniques like lock picking
- Modern Electronic Door Locks
- Utilize various authentication methods for enhanced security
- Authentication Methods:
- Identification Numbers
- Require entry of a unique code, providing a balance of security and convenience
- Wireless Signals
- Utilize technologies like NFC, Wi-Fi, Bluetooth, or RFID for unlocking
- Biometrics
- Rely on physical characteristics like fingerprints, retinal scans, or facial recognition for authentication
- Biometric Challenges
- False Acceptance Rate (FAR)
- Occurs when the system erroneously authenticates an unauthorized user
- Lower FAR by increasing scanner activity
- False Rejection Rate (FRR)
- Denies access to an authorized user. Increasing sensitivity can increase FRR
- Crossover Error Rate (CER)
- A balance between FAR and FRR for optimal authentication effectiveness
- Some electronic door locks use multiple factors, such as an identification number and fingerprint to increase security
- Cipher Locks
- Mechanical locks with numbered push buttons, requiring a correct combination to open
- Commonly used in high-security areas like server rooms
- Secure entry areas in office buildings, often use electronic access systems with badges and PINs for authentication
