Study Notes

  • Key fobs serve as compact RFID devices for accessing locked doors, attaching easily to keychains.
  • They offer the same proximity functionality as access cards in a smaller, more convenient form.
  • Smart cards contain certificates, verifying the cardholder's identity upon connection to a reader.
  • Smart cards are often combined with a PIN or passphrase for multi-factor authentication.
  • Card readers, either built-in or external via USB, are needed to read smart card certificates.
  • Mechanical locks with physical keys offer an alternative to electronic locks.
  • Key cabinets are used to manage and track physical keys in organizations.
  • Organizations often require collateral, like an ID or phone, when checking out physical keys.
  • Biometrics use physical traits like fingerprints, handprints, or retina scans for access.
  • Biometric readers create mathematical representations of scanned features.
  • Biometrics are hard to change and thus a reliable authentication method.
  • Combining biometrics with other factors like PINs improves authentication security.
  • Retina scanners identify users via unique capillary patterns in the eye.
  • Handprint readers use the entire hand for biometric identification.
  • Well-lit areas improve security by enhancing camera visibility.
  • Magnetometers (metal detectors) identify metallic objects, commonly found in airports and large buildings.
  • They cannot detect non-metallic materials like ceramics or plastics.
  • BYOD (Bring Your Own Device) refers to employees using personal mobile phones for work.
  • MDM (Mobile Device Manager) is used to manage and secure company data on personal devices.
  • MDMs enable IT to set usage policies, install apps, and control features on phones.
  • MDMs create logical partitions to separate personal and company data on devices.
  • MDMs can enforce security policies like screen locks and PINs on BYOD devices.
