EXIN ISFS study plan

EXIN ISFS · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Information security fundamentals and ISO/IEC 27001

  • Define information security and distinguish it from IT security and privacy, writing your own one-sentence definition and two contrasting examples

  • Explain the CIA triad (confidentiality, integrity, availability) and give a concrete business failure scenario for each leg

  • Relate the concepts of threat, vulnerability, risk, and control, and correctly classify ten short given scenarios into these four categories

  • Describe why information security is a management responsibility rather than a purely technical one, listing three organisational reasons

Your checkpoint

A one-page glossary of 15 core terms (information security, CIA triad, threat, vulnerability, risk, control, asset, impact, likelihood, and five more) with your own examples, self-scored against a checklist

Week 2

Information security fundamentals and ISO/IEC 27001

  • Map the structure of ISO/IEC 27001: its scope, normative references, terms, and the main clauses 4 through 10

  • Summarise the Plan-Do-Check-Act logic and explain how each main clause fits the cycle

  • Outline the role of Annex A and its control themes, and explain how Annex A relates to ISO/IEC 27002

  • Describe the concept of an Information Security Management System (ISMS) and what it means for an organisation to operate one

Your checkpoint

A hand-drawn or digital diagram of the ISMS clause structure mapped onto PDCA, annotated with one sentence per clause, reviewed for completeness

Week 3

Information security fundamentals and ISO/IEC 27001

  • Explain the purpose of a risk assessment and distinguish risk identification, risk analysis, and risk evaluation

  • Apply a simple qualitative risk matrix (likelihood x impact) to eight scenarios and rank them

  • Distinguish risk treatment options: mitigate, transfer, avoid, and accept, and justify a choice for each of four cases

  • Describe the role of a Statement of Applicability and explain why it is central to ISO/IEC 27001 certification

Your checkpoint

A completed risk register for a fictional 20-person company with at least 10 risks, each scored, ranked, assigned a treatment option, and an owner

Week 4

Information security fundamentals and ISO/IEC 27001

  • Describe the content and purpose of an information security policy and how supporting policies cascade from it

  • Explain the concepts of roles, responsibilities, segregation of duties, and the principle of least privilege

  • Outline awareness, training, and education as distinct activities and explain why awareness programmes matter

  • Summarise the human-factor controls around employment: screening, terms of employment, and termination of responsibilities

Your checkpoint

A draft one-page information security policy for the fictional company, plus a role-responsibility matrix covering at least six roles

Week 5

Information security fundamentals and ISO/IEC 27001

  • Classify assets and explain information classification schemes and labelling

  • Describe physical and environmental controls: zoning, access control, clear desk and clear screen, and equipment protection

  • Explain access control concepts: identification, authentication, authorisation, and accountability, and how they chain together

  • Distinguish authentication factors (something you know, have, are) and give a realistic example of multi-factor authentication

Your checkpoint

An asset inventory of 12 items with classification levels, owners, and the matching access control rule for each, plus a short note on how accountability is logged

Week 6

Information security fundamentals and ISO/IEC 27001

  • Explain the purpose of incident management and outline the phases from detection through evaluation, response, and learning

  • Distinguish an event, an incident, and a weakness, and classify ten given examples

  • Describe business continuity and disaster recovery at a conceptual level and distinguish RTO from RPO

  • Explain the role of supplier relationships and third-party risk in an ISMS

Your checkpoint

An incident response runbook outline for one scenario (lost laptop) with named roles, escalation steps, and three lessons-learned questions

Week 7

Information security fundamentals and ISO/IEC 27001

  • Describe the purpose of internal audit, management review, and continual improvement in the ISMS cycle

  • Distinguish a nonconformity from an observation and outline corrective action steps

  • Explain the difference between certification, accreditation, and conformity assessment in the ISO/IEC 27001 context

  • Identify the main performance evaluation inputs and outputs a management review expects

Your checkpoint

A mock internal audit checklist of 20 questions mapped to ISMS clauses, with a short management review agenda

Week 8

Information security fundamentals and ISO/IEC 27001

  • Consolidate all eight weeks into a single concept map linking terms, clauses, and controls

  • Answer 60 practice questions under timed conditions and review every wrong answer to its source concept

  • Re-explain the five weakest concepts aloud or in writing without notes

  • Recite the ISMS clause structure and PDCA mapping from memory

Your checkpoint

A timed 60-question mock exam with a written error log listing each missed concept, its correct definition, and a one-line memory hook

Milestones

Week 2: Can draw the ISO/IEC 27001 clause structure and PDCA mapping from memory and explain each clause in one sentence

Week 4: Risk register is complete and internally consistent: every risk has a score, a treatment, and an owner, and the Statement of Applicability rationale is explainable

Week 6: Can distinguish event, incident, and weakness correctly on at least 9 of 10 examples, and explain RTO versus RPO without notes

Week 8: Scores at least 80 percent on the timed 60-question mock and has a written error log covering every missed item
