Physical Privacy and Security Components 🔒

Confidentiality and the CIA Principle 🛡️

Confidentiality is a key aspect of the CIA Principle (Confidentiality, Integrity, Availability). It involves protecting data and networks from unauthorized access. Failure to ensure confidentiality can lead to reputational damage, loss of customers, legal liabilities, and financial losses. IT Support specialists play a crucial role in safeguarding confidential information.

Types of Authentication Methods 🔐

1. Something You Know: Passwords or PINs.

2. Something You Have: Physical items like bank cards, USB devices, key fobs, or OTPs (One-Time Passwords).

3. Something You Are: Biometric data such as fingerprints, voice signatures, facial recognition, or retinal scans.

4. Somewhere You Are: Geofencing, GPS, Indoor Positioning Systems (IPS).

5. Something You Do: Gestures, swipe patterns, CAPTCHA, or behavioral patterns.

Biometric Authentication 🧬

• Enrollment and Authentication:

  • Enrollment: Initial capture and storage of biometric data.

  • Authentication: Comparing new scans with stored data to verify identity.

• Types of Biometric Authentication:

  • Fingerprint Scanning: Uses capacitive sensors to detect fingerprint ridges; susceptible to dirt and moisture.

  • Facial Recognition: Requires color and infrared cameras to ensure 3D recognition; prevents access using 2D photos.

  • Iris Scanning: Uses infrared to scan unique patterns in the retina; highly secure but expensive and sensitive to eye conditions.

  • Retinal Scanning: Extremely secure by analyzing unique retinal blood vessel patterns; challenging to replicate but costly.

Geolocation and NFC Authentication 🌍

• Geolocation:

  • Geofencing: Restricts access based on proximity to a specific location.

  • GPS: Uses satellites to determine location; requires GPS-enabled devices.

  • IPS: Uses WiFi, cell towers, and Bluetooth for indoor location triangulation; may restrict access in certain areas.

• Near Field Communication (NFC):

  • NFC: Enables contactless payments and access control; operates at a short range (10 cm) but is vulnerable to interception by rogue scanners.

Behavioral Authentication 🧩

• Gestures and Behaviors:

  • Gestures: Swipe patterns or Picture Passwords for device access.

  • Behavioral Patterns: Monitors login/logout times and other patterns to detect anomalies.

  • CAPTCHA: Differentiates humans from bots by challenging users to identify items in images.

Key Takeaways 📌

• Five Types of Authentication:

  1. Something you know

  2. Something you have

  3. Something you are

  4. Somewhere you are

  5. Something you do

• Importance: Implementing diverse MFA protocols helps protect data and networks, enhancing overall security.
