Security Fundamentals: ATM, Biometrics, Transposition Cipher Analysis

This assignment addresses key concepts in information security, covering ATM security, biometric technologies, and transposition ciphers. The first section defines ATM systems, detailing confidentiality, availability, and integrity. The second section uses permutation to calculate the maximum PIN attempts for an ATM. The third section discusses the limitations of biometric technologies, including accuracy, cost, and security issues. The fourth section explores scenarios leading to false negatives in biometric authentication. Finally, the fifth section explains the transposition cipher technique and demonstrates its encryption and decryption process with an example. The assignment provides a comprehensive analysis of these security fundamentals, supported by cited references.
