Output of compliance log extraction command

You run the command to extract compliance logs from a SCADA system:

scada-cli export-logs --start 2024-01-01 --end 2024-01-02 --format json

What is the expected output format?

SCADA systems

scada-cli export-logs --start 2024-01-01 --end 2024-01-02 --format json

A Error: Unsupported format 'json' for export-logs

B <logs><log><timestamp>2024-01-01T00:00:01Z</timestamp><event>sensor_read</event><value>23.5</value></log></logs>

C

timestamp,event,value
2024-01-01T00:00:01Z,sensor_read,23.5

D [{"timestamp": "2024-01-01T00:00:01Z", "event": "sensor_read", "value": 23.5}, {"timestamp": "2024-01-01T00:05:00Z", "event": "alarm_trigger", "value": "high_temp"}]

💡 Hint

The command specifies JSON format, so the output should be a JSON array.

The command uses --format json, so the output is a JSON array of log objects with timestamp, event, and value fields.

Purpose of compliance reporting in SCADA systems

Why is compliance reporting critical in SCADA systems?

A To document and verify adherence to security and operational policies

B To ensure system uptime by automatically restarting devices

C To optimize sensor data for faster processing

D To provide real-time control commands to field devices

💡 Hint

Think about rules and regulations in industrial control environments.

Compliance reporting documents that the SCADA system follows required security and operational policies, which is essential for safety and audits.

❓ Troubleshoot

Troubleshooting missing compliance logs

You notice that compliance logs for a critical time period are missing after running the export command. Which is the most likely cause?

A The network connection was too slow to export logs

B The export command was run with the wrong output format

C The SCADA system's clock was incorrectly set during that period

D The sensor data was corrupted and deleted automatically

💡 Hint

Consider what affects log timestamps and retrieval.

If the system clock is wrong, logs may have incorrect timestamps and not appear in the requested time range.

🔀 Workflow

advanced

Steps to generate a compliance report

What is the correct order of steps to generate a compliance report from SCADA logs?

A 2,1,3,4

B 1,2,3,4

C 1,3,2,4

D 3,1,2,4

💡 Hint

Think about the logical order from data extraction to submission.

First export logs, then process them, review the results, and finally submit the report.

Best practice for securing compliance reports

Which practice best secures compliance reports generated from SCADA systems?

A Encrypt reports and restrict access to authorized personnel only

B Store reports on a publicly accessible server for easy access

C Send reports via unencrypted email to all team members

D Print reports and keep physical copies only

💡 Hint

Think about confidentiality and controlled access.

Encrypting reports and limiting access protects sensitive compliance data from unauthorized viewing.
