SecOT+ Legacy System Risk in OT Environments

1. True or False: Legacy OT systems are immune to cyber attacks because they use older technologies.

True

False

2. Which scenario best represents a residual risk in OT security?

Risk remaining after mitigation controls are implemented

Risk that existed before any security measures were taken

Risk that affects only IT systems, not OT

Risk that is completely eliminated by firewalls

Submit

4. Select all appropriate responses to identified risks in legacy OT systems:

Risk mitigation through technical controls

Risk acceptance with documented justification

Risk elimination through system replacement

Risk denial and ignoring vulnerabilities

Risk transfer through insurance

Submit

5. What is the relationship between asset criticality and risk prioritization in OT environments?

Higher criticality assets require more intensive risk mitigation efforts

All assets should receive equal security investment regardless of function

Asset criticality is irrelevant to risk assessment

Only non-critical assets need security controls

6. True or False: Network segmentation is unnecessary if OT systems are connected only to trusted internal networks.

True

False

Submit

8. Which of the following represents the highest risk in a legacy OT system?

Unpatched critical vulnerability exposed to an untrusted network

Employees using strong passwords

Regular security awareness training

Documented system architecture

Submit

10. What is the primary goal of implementing defense-in-depth in OT environments?

Create multiple layers of security controls to mitigate single points of failure

Eliminate all legacy systems immediately

Reduce the number of security professionals needed

Increase network bandwidth

11. What is the primary difference between IT and OT security risk management?

IT focuses on data availability; OT prioritizes safety and continuity of operations

OT systems use only proprietary protocols that cannot be breached

IT requires constant patching; OT systems never need updates

OT environments have no regulatory compliance requirements

12. In risk assessment, what does 'threat' specifically refer to?

A potential adversary or attack vector targeting OT systems

The cost of security implementation

The age of installed equipment

The number of system users

13. Select all factors that increase risk in legacy OT environments:

Inability to patch systems without downtime

Lack of encryption in communications

Presence of air-gapped networks

Use of outdated authentication methods

Frequent security audits

Submit

14. Which compliance framework most directly applies to critical infrastructure OT security?

NIST Cybersecurity Framework and IEC 62443

GDPR and HIPAA

PCI-DSS only

SOC 2 Type II exclusively

Submit

16. Which risk mitigation strategy is most appropriate for legacy OT systems that cannot be patched?

Implement network segmentation and intrusion detection systems

Disable all network connections permanently

Increase employee access to compensate for lack of patches

Rely solely on antivirus software for protection

17. True or False: Legacy OT systems can safely operate without network segmentation if they are internally monitored.

True

False

18. In SecOT+ frameworks, what does the 'risk' component primarily assess?

The likelihood and impact of security threats on OT systems

The cost of replacing all legacy equipment

The speed at which data travels through the network

The number of employees with system access

19. Which of the following is NOT a common vulnerability in legacy OT systems?

Absence of built-in encryption

Default or hardcoded credentials

Inability to support security patches

Excessive real-time monitoring capabilities

Submit
