Introduction

Government organizations require strong cyber security practices because they handle sensitive information related to national security, citizens’ data, and critical infrastructure. Candidates applying for government cyber security roles need to be well-versed not only in technical defense mechanisms but also in governance, risk management, and compliance frameworks.

In Canada, the Communications Security Establishment (CSE) developed ITSG-33, a widely adopted security risk management standard. Similarly, SABI ensures that systems undergo proper assessment and authorization before being deployed. These frameworks are essential for ensuring that systems meet Canadian government security standards.

In the following sections, we will explore interview questions and answers categorized under different themes: general government cyber security, CSE ITSG-33, SABI, Canadian government security standards, and compliance/audit-related topics.

Government Cyber Security Interview Questions and Answers

Question 1: Why is cyber security critical in government organizations?

Answer: CSE ITSG-33 is a Canadian standard called “IT Security Risk Management: A Lifecycle Approach.” It provides guidance on managing IT security risks throughout the system development lifecycle. It is closely aligned with international standards and supports risk-based decision-making.

Question 7: How is ITSG-33 structured?

Answer: ITSG-33 is divided into two main parts:

  • A risk management framework for organizations that outlines governance, roles, and responsibilities.
  • A security control catalogue that provides detailed technical and management security controls aligned with system lifecycles.

Question 8: How do you apply ITSG-33 in practice?

Answer: The process begins with identifying business needs and risks, selecting applicable security controls from the ITSG-33 catalogue, implementing those controls, and continuously monitoring system security throughout its lifecycle.

Question 9: What is the difference between ITSG-33 and NIST standards?

Answer: ITSG-33 is Canada-specific but harmonized with international standards like the NIST Risk Management Framework. While the core principles are similar, ITSG-33 is tailored to Canadian government needs, policies, and terminology.

Question 10: How do you conduct a security control assessment under ITSG-33?

Answer: I begin by identifying the applicable controls, creating a test plan, performing technical and procedural assessments, documenting findings, and then making recommendations. Results are presented as part of the system’s authorization process.

SABI Cyber Security Interview Questions and Answers

Question 11: What is SABI in the Canadian government security context?

Answer: SABI stands for Security Assessment and Authorization for Business Information Systems. It is a framework that ensures systems are assessed against security controls and authorized before being deployed in production.

Question 12: Why is SABI important?

Answer: SABI provides assurance that government systems meet minimum security standards, reducing the risk of unauthorized access, data breaches, and system compromises. It supports risk-informed decision-making for authorizing system operations.

Question 13: What are the main steps in the SABI process?

Answer: The main steps include defining the system, selecting and implementing security controls, conducting an independent assessment, preparing a security assessment report, and finally obtaining authorization from the designated authority.

Question 14: How does SABI align with ITSG-33?

Answer: SABI uses ITSG-33 as a foundation for control selection and assessment. While ITSG-33 provides the framework and catalogue of controls, SABI defines the process for assessing and authorizing government systems.

Question 15: How do you ensure continuous monitoring under SABI?

Answer: Continuous monitoring involves updating risk assessments, performing vulnerability scans, applying patches, and revalidating controls regularly. It ensures that systems remain compliant even as threats and technologies evolve.

Canadian Government Security Standards Interview Questions

Question 16: What are some common Canadian government security standards?

Answer: Key standards include ITSG-33, the Policy on Government Security (PGS), the Directive on Security Management (DSM), and specific requirements for classified systems. These standards guide organizations in managing IT risks and compliance.

Question 17: How do Canadian standards compare with international ones?

Answer: Canadian standards are often harmonized with global frameworks like ISO 27001 and NIST, but tailored to meet Canadian legal and policy requirements. This ensures interoperability while addressing domestic security needs.

Question 18: What is the Policy on Government Security (PGS)?

Answer: The PGS is a Government of Canada policy that establishes responsibilities and expectations for safeguarding government assets, information, and services. It works in coordination with ITSG-33 and other security frameworks.
