What does the CIA triad stand for in information security?
CIA stands for Confidentiality, Integrity, and Availability — the three core principles that guide IT security policies in banking environments.
What is the difference between a virus and a worm in the context of banking malware?
A worm self-replicates across networks without human action, unlike a virus.
What is the purpose of a Public Key Infrastructure (PKI) in banking communication?
PKI provides a framework of digital certificates, certificate authorities, and registration authorities to enable secure, authenticated, and encrypted communication between parties in banking transactions.
What is a honeypot in network security and how do banks use it?
A decoy system that lures attackers to detect and study intrusion attempts.
What is the difference between symmetric and asymmetric encryption?
Symmetric encryption uses the same key for encryption and decryption, while asymmetric encryption uses a public-private key pair — asymmetric is used for secure key exchange and digital signatures in banking.
What is the purpose of a digital watermark in banking document security?
It embeds invisible identifiers to prove ownership and detect document tampering.
What is SSL/TLS and why is it critical for digital banking?
SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols that establish encrypted communication channels between clients and banking servers, protecting data in transit.
What is the role of Transport Layer Security (TLS) 1.3 in modern banking communication?
It provides faster, stronger encryption for secure data transmission between client and server.
