SOC Technology & Digital Tools 3 — Questions and Answers
Question 1: In a SOC 1 engagement, a service organization processes payroll on behalf of user entities. Which technology control is most relevant to ensuring input completeness?
- Hash totals or record counts validated between submitted files and processed records (Correct answer)
- Antivirus scans on uploaded payroll files
- Encryption of payroll data in transit
- Role-based access to payroll reports
Correct answer: Hash totals or record counts validated between submitted files and processed records
Hash totals and record counts are automated controls that verify all submitted payroll records were received and processed without loss or duplication.
Question 2: A SOC 2 report covers a cloud provider's vulnerability management program. What technology provides the foundational evidence of this program's operation?
- A data loss prevention (DLP) tool
- Scheduled vulnerability scanner reports showing identified and remediated findings (Correct answer)
- A web application firewall (WAF) blocking report
- Employee phishing simulation results
Correct answer: Scheduled vulnerability scanner reports showing identified and remediated findings
Scheduled vulnerability scanner reports demonstrating identified findings and their remediation provide direct evidence that a vulnerability management program is operating effectively.
Question 3: When assessing the availability trust service criteria, an auditor would most likely examine which technology artifact?
- Penetration test reports
- System uptime monitoring dashboards and incident response logs (Correct answer)
- Data classification policies
- User authentication logs
Correct answer: System uptime monitoring dashboards and incident response logs
Uptime monitoring dashboards and incident response logs directly evidence that the organization monitors system availability and responds to disruptions.
Question 4: What is the significance of immutable audit logs in the context of a SOC examination?
- They prevent unauthorized users from viewing log data
- They ensure log records cannot be altered or deleted, preserving the integrity of the audit trail (Correct answer)
- They compress log data to reduce storage costs
- They automate the reporting of security events to management
Correct answer: They ensure log records cannot be altered or deleted, preserving the integrity of the audit trail
Immutable logs preserve the integrity of the audit trail, ensuring evidence of system activities cannot be tampered with, which is critical for SOC monitoring controls.
Question 5: A service organization uses a cloud access security broker (CASB). Which SOC 2 trust service criteria does this tool most directly support?
- Processing integrity
- Confidentiality and security, by enforcing policies on data moving to and from cloud services (Correct answer)
- Availability, by routing traffic during outages
- Privacy, by anonymizing user identities in cloud apps
Correct answer: Confidentiality and security, by enforcing policies on data moving to and from cloud services
A CASB enforces security and data handling policies for cloud services, directly supporting the confidentiality and security trust service criteria.
Question 6: During a SOC 2 Type II audit, the auditor tests controls over a 12-month period. Which technology evidence best demonstrates continuous operation of a backup control?
- A current backup policy document signed by the CISO
- Automated backup job logs showing successful execution and periodic restoration test records throughout the period (Correct answer)
- A list of all data classified as critical
- A vendor contract with a backup software provider
Correct answer: Automated backup job logs showing successful execution and periodic restoration test records throughout the period
Backup job logs and restoration test records over the audit period provide evidence that the control operated consistently throughout the examination window.
Question 7: Which technology tool would provide the best evidence that a service organization is monitoring for unauthorized data exfiltration?
- Intrusion prevention system (IPS) blocking logs
- Data loss prevention (DLP) system alerts and incident records (Correct answer)
- Endpoint encryption status reports
- Password manager audit logs
Correct answer: Data loss prevention (DLP) system alerts and incident records
A DLP system is specifically designed to detect and prevent unauthorized data transfers, and its alert and incident records evidence that exfiltration monitoring is active.
