Understanding Threat in Years 9–10 Digital Systems

What it does: Deliberate threats involve intent to cause harm, so the code labels the threat as deliberate. Internal threats come from people or systems inside the organisation, while external threats come from outside it. A threat is anything that could harm an asset. A weakness in a system is a vulnerability, which is a different idea. The harm was not intended. Human error is an accidental threat. This card is wrong because it limits threats to hackers, ignoring accidental threats like power failures.

Common mistakes: A phishing email is sent on purpose by an attacker, so it is a deliberate threat. The line should be intent = "deliberate". Antivirus software protects an asset, so it is a security control and not a threat. A threat is something that could cause harm, such as a power failure.

Quick Questions

1. Which best describes a threat in digital security?

A. Anything that could cause harm to an asset ✓

B. A weakness that is always fixed by an update

A threat is anything that could harm an asset. A weakness in a system is a vulnerability, which is a different idea.

2. Which one is a threat to a school's student records?

A. A power failure that corrupts the server ✓

B. A strong password on the server

A power failure could damage the asset, so it is a threat. A strong password helps protect the asset, so it is not a threat.

3. A hacker deliberately tries to steal a company's customer data. What type of threat is this?

A. Accidental threat

B. Deliberate threat ✓

The hacker is acting on purpose to cause harm, so this is a deliberate threat.

4. A student accidentally deletes a shared class folder. What type of threat is this?

A. Accidental threat ✓

B. Deliberate threat

The harm was not intended. Human error is an accidental threat.

5. An unhappy employee copies private files before leaving the company. Which type of threat is this?

A. External threat

B. Internal threat ✓

The person already has legitimate access inside the organisation, so this is an internal threat. It is also deliberate.

Match the Pairs

threat → Anything that could cause harm to an asset, such as an attacker, malware, human error or a power failure

threat_type = "accidental" → A threat with no intent to cause harm, such as a student deleting a file by mistake

A deliberate threat is caused on purpose, like a hacker trying to steal data → threat_type = "deliberate"

An internal threat comes from inside the organisation, like a staff member who clicks a bad link → threat_source = "internal"

A threat must always be a hacker, so a power failure is not a threat → A threat can be anything that could harm an asset, including malware, human error and power failures, not just attackers.

threat_source = "internal" for a stranger hacking in from overseas → A stranger hacking from overseas is an external threat, not an internal one. The label should be "external".

Key Term

threat

Anything that could cause harm to an asset, such as an attacker, malware, human error or a power failure. Threats can be deliberate or accidental, and internal or external.

Fill in the Blanks

1. asset ← "school laptop" threat ← "malware"

Hint: Type the variable name for anything that could cause harm to the asset.

2. threat ← "phishing attack" intent ← "deliberate"

Hint: Type the intent word for a threat where someone is purposely trying to cause harm.

3. threat ← "spilled drink" intent ← "accidental"

Hint: Type the intent word for a threat caused by a mistake, not by someone trying to cause harm.

4. threat ← "hacker overseas" source ← "external"

Hint: Type the source word for a threat that comes from outside the organisation.

5. threat ← "staff share password" source ← "internal"

Hint: Type the source word for a threat that comes from inside the organisation, such as its own people.

Spot the Error

Question 1

A asset = "student records"

B threat = "phishing email"

C intent = "accidental"

D source = "external"

Line C — A phishing email is sent on purpose by an attacker, so it is a deliberate threat. The line should be intent = "deliberate".

Question 2

A threat = "antivirus software"

B intent = "accidental"

C source = "external"

Line A — Antivirus software protects an asset, so it is a security control and not a threat. A threat is something that could cause harm, such as a power failure.

Question 3

A threat = "staff typo"

B source = "external"

C intent = "accidental"

Line B — A typo made by a staff member comes from inside the organisation, so it is an internal threat. The line should be source = "internal".

Question 4

A threat = "hacker"

B if threat = "hacker":

C print("Deliberate threat")

Line B — A single = assigns a value. To compare values in a condition you need ==. The line should be if threat == "hacker":.

Question 5

A threats = ["malware", "typo"]

B for t in threats

C print(t)

Line B — A for loop line must end with a colon. The line should be for t in threats:.
