Easy: fundamentals
Governance, risk and compliance basics.
What is GRC? easy
Governance (direction, roles, policy), Risk management (identify, assess, treat) and Compliance (meeting laws, standards and contracts). Together they connect security work to business objectives and obligations.
What is the CIA triad? easy
Confidentiality (only authorised access), Integrity (data stays accurate and unaltered) and Availability (systems are usable when needed). Risk assessments consider impact on each.
Policy, standard, procedure and guideline? easy
A policy states management intent (mandatory, high level). A standard sets specific requirements. A procedure gives step-by-step instructions. A guideline is advice. Keep them layered and owned.
What are the main risk treatment options? easy
Mitigate (add controls), transfer (insurance, contracts), avoid (stop the activity) or accept (formally, with owner sign-off). Residual risk remains after treatment.
What is the difference between an audit and an assessment? easy
An audit independently checks conformance against a defined standard and produces formal findings. An assessment evaluates posture or risk more broadly and may be advisory.
What are ISO 27001 and SOC 2? easy
ISO/IEC 27001 certifies an information security management system (the 2022 edition has 93 Annex A controls). SOC 2 is an attestation report against Trust Services Criteria (security, availability, processing integrity, confidentiality, privacy). Type I tests design at a point in time, Type II tests operating effectiveness over a period.
Medium: applied
Risk, frameworks and process.
Describe a risk assessment process. medium
Define scope and criteria, identify assets, threats and vulnerabilities, estimate likelihood and impact (qualitative or quantitative), calculate and rank risk, choose treatments, record in a risk register with owners and dates, and review regularly.
Qualitative versus quantitative risk analysis? medium
Qualitative uses ratings (low, medium, high) and is quick but subjective. Quantitative uses numbers: single loss expectancy times annual rate of occurrence gives annualised loss expectancy, or approaches like FAIR that model loss frequency and magnitude. Quantitative supports cost-benefit decisions but needs good data.
What is NIST CSF 2.0? medium
A voluntary framework organising outcomes into six functions: Govern, Identify, Protect, Detect, Respond and Recover. Govern was added in version 2.0. Organisations use profiles and tiers to assess current and target state.
What is the difference between a control framework and a regulation? medium
Frameworks (NIST CSF, ISO 27001, CIS Controls) are guidance or certifiable standards adopted voluntarily. Regulations (GDPR, HIPAA, PCI DSS rules via contracts, India DPDP Act, RBI directions) are legally or contractually binding.
What is third-party risk management? medium
Assessing and monitoring vendors that touch your data or systems: due diligence questionnaires, evidence review (SOC 2, ISO), contractual security and breach notice terms, access limitation, continuous monitoring and exit planning. Tier vendors by criticality.
How do you prepare for an audit? medium
Understand scope and criteria, map controls to evidence, collect and test evidence beforehand, fix gaps, brief control owners, keep a single point of contact, and track findings to closure. Continuous control monitoring beats annual panic.
What is data classification and why does it matter? medium
Labelling data by sensitivity (public, internal, confidential, restricted) so controls match risk: access, encryption, retention and sharing. It underpins DLP, privacy and cloud decisions.
Explain key privacy principles in GDPR-style laws. medium
Lawfulness and transparency, purpose limitation, data minimisation, accuracy, storage limitation, integrity and confidentiality, and accountability. Subjects have rights of access, correction and erasure. Breaches must be notified (72 hours to the authority under GDPR).
What are Key Risk Indicators and how do they differ from KPIs? medium
KRIs signal rising risk (unpatched critical systems, privileged accounts without MFA). KPIs measure performance against goals (percentage of staff trained). Both feed dashboards and decisions.
Hard: depth
Leadership and judgment.
How do you translate technical risk for the board? hard
Use business language: what could happen, how likely, financial and operational impact, how it compares with appetite, options with cost, and the decision needed. Use a few meaningful metrics and trends, avoid jargon, and tie to strategic objectives.
How do you define and use risk appetite and tolerance? hard
Appetite is the amount of risk the organisation is willing to pursue, set by leadership. Tolerance sets acceptable variation around objectives. They guide which risks need treatment versus acceptance and when to escalate.
How do you handle a control that is failing but business-critical? hard
Document the gap, assess impact, apply compensating controls, set a remediation plan with owner and date, record time-bound risk acceptance by an authorised executive, and report to the risk committee until closed.
How do you build one control set that satisfies several standards? hard
Create a unified control framework: map requirements from ISO 27001, SOC 2, PCI DSS and local laws to common controls, collect evidence once, and report against each standard. It cuts duplicate audit effort.
What should a good incident notification process include for compliance? hard
Defined triggers and roles, a legal and privacy review step, notification templates, deadlines per regulator (such as GDPR 72 hours and CERT-In reporting windows), customer contract obligations, evidence retention and a decision log.
Compliance does not equal security. Explain. hard
Standards set a baseline at a point in time and can be satisfied on paper. Attackers do not care about audits. Use compliance as a minimum, drive real risk reduction through testing, detection and response, and measure outcomes, not just checklists.
Scenarios
Make a recommendation.
Sales needs a SOC 2 report in six months to win a large customer. What is your plan? hard
Scope the system and criteria, run a gap assessment, prioritise missing controls and evidence, choose Type I as a first step if timing requires then move to Type II, automate evidence collection, assign owners and track weekly.
An engineering team wants to use a new SaaS tool with customer data. How do you assess? hard
Classify the data, run a vendor risk review (security evidence, data location, subprocessors, breach terms), check integration and access design, set contract terms, and approve with conditions or propose alternatives.
The audit finds that user access reviews were not performed. What do you do? hard
Acknowledge the finding, perform the review immediately, remove inappropriate access, assign an owner and calendar, automate reminders and evidence, and show the corrective action to the auditor.
GRC interviews test judgment and communication. Explain frameworks simply, show how you reach a risk decision, and give examples of influencing without authority. Always connect a control to the risk it reduces and the evidence that proves it works.
