Availability is the information security element that ensures that Stella’s transaction status is immediately reflected in her bank account in this scenario. Information security is the practice of protecting information and information systems from unauthorized access, use, disclosure, modification, or destruction. Information security can be based on three fundamental principles: confidentiality, integrity, and availability. Confidentiality is the principle that ensures that information is accessible only to authorized parties and not disclosed to unauthorized parties. Integrity is the principle that ensures that information is accurate, complete, and consistent and not altered or corrupted by unauthorized parties. Availability is the principle that ensures that information and information systems are accessible and usable by authorized parties when needed. In the scenario, Stella purchased a smartwatch online using her debit card. After making payment for the product through the payment gateway, she received a transaction text message with a deducted and available balance from her bank. This means that her transaction status was immediately reflected in her bank account, which indicates that availability was ensured by her bank’s information system. 

In the context of developing a cryptographic protocol resilient against quantum computing attacks, SHA-3 is the most appropriate choice. Here’s why:

Quantum Computing Threats: Quantum computers can potentially break current cryptographic methods like RSA and ECC due to Shor's algorithm. Traditional hash functions like SHA-256 might not offer sufficient security in a post-quantum world.

SHA-3 Overview: SHA-3, part of the Secure Hash Algorithm family, was designed with quantum resistance in mind. It was selected through an open competition by NIST, ensuring it incorporates advanced cryptographic techniques.

Resilience: SHA-3’s design is fundamentally different from SHA-2, providing enhanced security properties, including resistance to various attack vectors that might be feasible with quantum computing advancements.

For NexaCorp to effectively monitor and analyze system logs, implementing a Security Information and Event Management (SIEM) system is the optimal approach:

SIEM Overview: SIEM systems collect, normalize, and analyze log data from various sources in real-time.

Benefits:

Centralization: Aggregates logs from all systems into a single platform.

Correlation: Identifies patterns and correlates events from different sources to detect anomalies.

Implementation Steps:

Select a SIEM Solution: Choose a suitable SIEM tool (e.g., Splunk, ELK Stack, QRadar).

Integration: Configure the SIEM to collect logs from all relevant systems.

Alerting and Reporting: Set up alerts for suspicious activities and generate periodic reports.
