Teaching notes for Lesson 5.3, with controls for presenting it.
Keep this page on your own screen. Share only the lesson window. The lesson window holds no teaching notes, so sharing it cannot show them.
Presenting
- Open the lesson in its own window and share that window, not this one.
- Use Next and Previous here, or the lesson’s own, to move through the lesson. Next reveals one thing at a time: the next idea, or the answer to the question on screen, then the next step. Previous takes the last reveal back. The line below says what is on screen and what Next will show.
- Reveal hints and answers when the class is ready, and reset a demonstration before using it again.
The controls need JavaScript and a browser that supports BroadcastChannel. Without them, open the lesson in presentation mode and use its own controls.
The two windows talk to each other only inside this browser, on this device. Nothing is sent to a server, and no account is needed. A second device (a phone or another tablet) cannot follow the lesson window yet.

Learners build the parts of a risk from a house before any term is used, including a house with a broken window and nothing inside, which shows that a weakness is not a risk on its own. The parts are then named and used to write a risk as a scenario sentence, which learners draft before seeing the lesson's. Predictions precede business context (one hour's outage, two systems), a second route to the same database, and the difference between a flaw nobody has found and one with an uninstalled fix. The habit to build: write a risk as a sentence, not the name of an asset.
Objectives
- Describe a risk as what could happen, how likely it is and how much it would matter to this organisation
- Tell assets, threats, vulnerabilities, incidents, impact and likelihood apart
- Write a risk as a scenario sentence, and see how changing one fact changes it
- Explain what the three common risk models show, and why they are not calculations
- Tell a zero-day from a known, unpatched vulnerability, and explain why it matters
Before the lesson
- Open this page on your own screen and use “Open the lesson window” to open the lesson in a second window. Share only that second window.
- Learners need the CIA Triad and GRC lessons first.
- Have somewhere to collect the house answers, ready to sort into five unlabelled groups in the second step.
- The lesson takes about 58 minutes.
- In presentation mode every step is shown in turns: Next reveals one moment, part or answer at a time, and the instructor view names what is on screen and what comes next.
Steps
Introduction Opening
On the lesson window now
On screen: the lesson’s title, module and number; Next adds its objectives and key terms, as the lesson page lists them; Next again begins the first step.
Objectives on screen
- Describe a risk as what could happen, how likely it is and how much it would matter to this organisation
- Tell assets, threats, vulnerabilities, incidents, impact and likelihood apart
- Write a risk as a scenario sentence, and see how changing one fact changes it
- Explain what the three common risk models show, and why they are not calculations
- Tell a zero-day from a known, unpatched vulnerability, and explain why it matters
Purpose: Learners build the parts of a risk from a house before any term is used, including a house with a broken window and nothing inside, which shows that a weakness is not a risk on its own. The parts are then named and used to write a risk as a scenario sentence, which learners draft before seeing the lesson's. Predictions precede business context (one hour's outage, two systems), a second route to the same database, and the difference between a flaw nobody has found and one with an uninstalled fix. The habit to build: write a risk as a sentence, not the name of an asset.
1. A house in the street Think 6 min
On the lesson window now
Purpose: Collect the parts of a risk from a familiar situation, and see that a weakness alone is not a risk.
Ask
- What would make a house more or less at risk of burglary?
- Broken window, empty house: how much does the window matter?
Responses to expect
- “Valuables on show”, “an open window”, “a street with break-ins”, “a neighbour at home”.
- Some say the window is always serious. Ask what a burglar could take.
- On screen in turns: the opening question, its answer; then the question on an empty house, and its answer.
Discussion pause: Collect the list before moving on; do not sort it yet.
In the lesson window
- Think it through: Think of a house. What would make it more at risk of being burgled, and what would make it less?
- Think it through: A house has a window that does not lock. Nobody lives there and there is nothing inside worth taking. How much does the window matter?
2. The idea Explain 5 min
On the lesson window now
Purpose: Sort the learners' list into the five parts, and state what risk is.
Ask
- Which of your answers fit each of the five groups?
Responses to expect
- Most lists cover all five once sorted; likelihood and impact are the two most often merged.
- On screen in turns: the opening; then the parts of a burglary risk, starting with something worth taking; someone who might take it; a way in; how likely it is; how much it would matter; take one part away; cybersecurity risk; the question an organisation asks.
3. Assets, threats, vulnerabilities and business context Explain 9 min
On the lesson window now
Purpose: Name the parts, apply them to an organisation, and see why the same event matters differently in different places.
Ask
- School laptops: which is the threat, the vulnerability and the asset?
- An hour's outage on a test system and on hospital records: same risk?
Responses to expect
- The criminal group is often called the vulnerability; insist on “something that could cause harm” for a threat.
- On screen in turns: the opening; then each part named, with the house held back; the house equivalent of each; the control; one risk, link by link; the diagram’s stages one at a time; the check question on which is the vulnerability, and its answer; the question on the same hour in different places, and its answer; business context; where the house comparison stops.
Misconceptions to challenge
- A learner may believe: “A vulnerability is a risk.” Respond: It is one ingredient; recall the empty house.
Discussion pause: The house column is held back: ask the class to match each term to the burglary before revealing it. Then step through the chain one link at a time.
In the lesson window
- Check your understanding: A school’s laptops run an operating system that has not been updated for a year. A criminal group is known to target schools. Which is the vulnerability?
- Think it through: One hour’s interruption hits two systems: a test system that developers try new features on, and a hospital’s patient records system. Is the risk the same?
4. The customer-database scenario Experiment 5 min
On the lesson window now
Purpose: Have learners write a risk as a scenario sentence before reading the lesson's.
Ask
- Turn the five rows into one sentence.
Responses to expect
- First attempts often just name the database. Ask: who, through what weakness, with what harm?
- On screen in turns: the opening; then the question on writing it as a sentence, and its answer; the risk as a scenario; the questions that follow from it.
In the lesson window
- Think it through: Before reading on: turn the five rows of the table into one sentence that says what could happen and why it would matter.
5. A fictional example Predict 6 min
On the lesson window now
Purpose: Change one fact and see that one asset can carry several risks, each with its own likelihood and remedy.
Ask
- Same database, different way in: same risk?
Responses to expect
- Many say yes because the asset is the same. Ask whether one fix would stop both.
- On screen in turns: the opening question, its answer; then changing one fact, starting with the new scenario; comparing the parts; comparing the likelihood; comparing what would help; what the comparison shows.
Misconceptions to challenge
- A learner may believe: “One asset has one risk.” Respond: Each route to it is a separate risk.
If the explanation does not land: Return to the house: a burglar through the window, and a burglar with a copied key, need different fixes.
In the lesson window
- Think it through: Keep the same customer database, but imagine a different way in: an internet-facing web service that has not been updated. Is that the same risk as before?
6. Three risk models Explain 7 min
On the lesson window now
Purpose: Show what each risk model highlights, and that none is a calculation.
Ask
- Threat 4 × Vulnerability 3 × Asset 5 = 60. What does 60 mean?
Responses to expect
- Nothing measurable. Some will defend it; ask what the units are.
- The “what it is not” column is held back: ask what each model might be mistaken for before revealing it.
- On screen in turns: the opening; then three risk models, with what each is not held back; what each model is not; the empty house again; the check question on Threat × Vulnerability × Asset, and its answer; when numbers are multiplied, starting with a risk matrix; a quantitative model; the three models applied to one risk, starting with the three ingredients; impact and likelihood; what none of the models says.
Misconceptions to challenge
- A learner may believe: “The risk formulas are calculations.” Respond: They show what risk depends on; real numbers need a defined rating scheme or real units.
In the lesson window
- Check your understanding: A manager writes: “Threat 4 × Vulnerability 3 × Asset 5 = Risk 60.” What is wrong with this?
7. Four distinctions that are easy to blur Explain 3 min
On the lesson window now
Purpose: Consolidate four distinctions the later lessons rely on.
Ask
- Which of the four would you most likely mix up? Why?
Responses to expect
- Inherent and residual risk is the usual answer; it is developed in Treating Risk.
- On screen in turns: the opening; then four distinctions, starting with threat and vulnerability; impact and likelihood; risk and technical severity; inherent and residual risk.
8. Vulnerabilities and dependencies Predict 6 min
On the lesson window now
Purpose: Separate flaws nobody has found from flaws with an uninstalled fix, and introduce dependencies.
Ask
- Two flaws: which can the school remove today?
- A fix came out last month and has not been installed. Zero-day or not?
Responses to expect
- “Install updates for both” is common; ask whether an update can exist for an undiscovered flaw.
- Many say zero-day. The maker knows and has a fix.
- On screen in turns: the opening question, its answer; then two kinds of vulnerability, starting with the zero-day; the known, unpatched vulnerability; where no fix exists; the check question on a fix released last month, and its answer; suppliers and dependencies; turning a remark into an assessment.
Misconceptions to challenge
- A learner may believe: “Any unpatched vulnerability is a zero-day.” Respond: A zero-day is unknown to the maker; a flaw with a released fix is known and unpatched.
In the lesson window
- Think it through: A school uses two programs, each with a flaw. The maker of the first has not yet discovered its flaw. The maker of the second released a fix last week. Which flaw can the school remove today?
- Check your understanding: The maker of a program released a fix for a flaw last month, but a school has not installed it yet. Is the flaw a zero-day vulnerability at the school?
9. Apply it in a new situation Apply 4 min
On the lesson window now
Purpose: Set up independent application, ideally on a later day.
Ask
- Who will try these now, and who later in the week?
Responses to expect
- The sports-club question checks writing a risk as a scenario; the council question checks likelihood.
- On screen in turns: the opening; then the question on the sports club’s spreadsheet, and its answer; the question on a rare but catastrophic flood, and its answer.
In the lesson window
- Apply it: A sports club keeps its members’ contact details in a shared spreadsheet that anyone with the link can open. Which statement best describes the risk?
- Apply it: A town council says: “A flood could destroy our records office, so flooding is our biggest risk.” The office is on a hill and has never flooded. What is missing from the council’s reasoning?
10. Check your understanding Check 4 min
On the lesson window now
Purpose: Check the lesson against the approved revision-bank questions.
Ask
- Answer individually, then compare before revealing.
Responses to expect
- The same-flaw question links back to the change-one-fact example.
- On screen in turns: the opening; then the revision questions one at a time, each followed by its answer; where to practise next.
11. What to remember Consolidate 3 min
On the lesson window now
Purpose: Summarise the five points, the key terms and the misunderstandings, and point to Assessing Risk.
Ask
- Without looking: write one risk as a scenario sentence.
Responses to expect
- Threat, vulnerability, asset and impact in one sentence.
- On screen in turns: the opening; then the summary; the key terms; the common misunderstandings.
Lesson recap Closing
On the lesson window now
On screen: the lesson’s objectives again; Next adds the closing question, which asks the class to explain each one in their own words without looking back. It says nothing about what anyone has learnt: use the answers to decide what to revisit.
Points to listen for
- A risk is a scenario: what, to what, through which weakness, how likely, how much it matters.
- Remove a threat, a weakness or the asset, and that particular risk disappears.
- Different routes to one asset are different risks.
- The risk models describe dependence; they do not calculate.
- Known and unpatched is not the same as zero-day.
