ICS456 Essentials for NERC Critical
Infrastructure Protection Exam 2026 |
Questions and answers 2026 | Latest Update
1.
Which objective best describes the primary purpose of the NERC CIP standards?
A. Regulating electricity pricing across markets
B. Protecting bulk electric system cyber assets from compromise
C. Managing customer billing systems
D. Improving residential electrical wiring standards
Correct Answer: B
Rationale:
NERC CIP standards are designed to protect the cybersecurity and operational reliability of
the Bulk Electric System (BES) by safeguarding critical cyber assets.
2.
Under CIP asset categorization, which system classification represents the highest security risk
to the Bulk Electric System?
A. Low Impact BES Cyber Systems
B. Medium Impact BES Cyber Systems
C. High Impact BES Cyber Systems
D. Non-BES Cyber Systems
Correct Answer: C
Rationale:
High Impact BES Cyber Systems are those whose compromise could significantly affect the
reliability of the Bulk Electric System.
3.
,Which CIP standard governs electronic security perimeters and inbound/outbound
communication controls?
A. CIP-003
B. CIP-005
C. CIP-009
D. CIP-011
Correct Answer: B
Rationale:
CIP-005 focuses on Electronic Security Perimeters (ESPs) and controlling remote electronic
access to critical cyber assets.
4.
Which concept ensures that users only receive system privileges necessary for their job
functions?
A. Segmentation
B. Least privilege
C. Network redundancy
D. Role replication
Correct Answer: B
Rationale:
Least privilege minimizes security risk by limiting access rights to only those required for
specific job responsibilities.
5.
Which standard requires formal cybersecurity policies approved by senior management?
A. CIP-002
B. CIP-003
C. CIP-006
D. CIP-010
Correct Answer: B
,Rationale:
CIP-003 mandates governance structures, cybersecurity policies, and management oversight.
6.
What is the primary purpose of Electronic Security Perimeters (ESPs)?
A. Protecting substations from lightning strikes
B. Restricting electronic access to critical cyber assets
C. Managing billing transactions
D. Controlling employee payroll access
Correct Answer: B
Rationale:
ESPs create a controlled network boundary to monitor and restrict access to critical systems.
7.
Which security control most directly prevents unauthorized remote access to BES Cyber
Systems?
A. Multi-factor authentication
B. Data compression
C. Static IP assignment
D. Load balancing
Correct Answer: A
Rationale:
Multi-factor authentication (MFA) ensures stronger identity verification for remote access.
8.
Which CIP standard addresses personnel risk assessment and training requirements?
A. CIP-004
B. CIP-007
C. CIP-009
D. CIP-011
, Correct Answer: A
Rationale:
CIP-004 requires background checks, training, and personnel risk assessments for
individuals with access to BES Cyber Systems.
9.
What is the main goal of CIP-007 System Security Management?
A. Managing corporate finance systems
B. Maintaining secure configuration and patch management for cyber assets
C. Managing vendor contracts
D. Monitoring electricity demand
Correct Answer: B
Rationale:
CIP-007 focuses on system hardening, patching, malware prevention, and vulnerability
management.
10.
Which measure reduces the likelihood of malware propagation within operational technology
networks?
A. Network segmentation
B. Email encryption only
C. Printer redundancy
D. Power supply backups
Correct Answer: A
Rationale:
Segmentation isolates network zones to prevent malware from spreading across systems.
11.
Which CIP standard focuses on physical security of BES Cyber Systems?
