 Masking is the technique that Andre employed in the above scenario. Masking is a deidentification technique that can replace the critical information in database fields with special characters such as asterisks (*) and hashes (#). Masking can help protect sensitive data from unauthorized access or disclosure, while preserving the format and structure of the original data . Tokenization is a deidentification technique that can replace the critical information in database fields with random tokens that have no meaning or relation to the original data. Hashing is a deidentification technique that can transform the critical information in database fields into fixed-length strings using a mathematical function. Bucketing is a deidentification technique that can group the critical information in database fields into ranges or categories based on certain criteria.

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.

To analyze the IoT network traffic capture and identify the command sent to IoT devices, follow these steps:

Open the Capture File:

Use a network analysis tool like Wireshark to open theIoT_capture.pcapngfile.

Filter and Analyze:

Apply appropriate filters to isolate relevant traffic. Look for command patterns typically sent to IoT devices.

Identify the Command:

Upon analyzing the captured traffic, the commandForest_Fire_Alert444is identified as the one sent over the network to IoT devices during the attack.
