Cybercrime and threats, malware, encryption, passwords, access levels, backup, firewalls, protocols, FTP, HTTP and HTTPS.
How to study for CCEA GCSE Digital Technology
Connect precise digital concepts to scenario evidence, design decisions, testing and evaluation, then rehearse the controlled-practice lifecycle under your centre's current CCEA instructions.
Core concepts
Concept 1
Cybersecurity threats differ by goal and method, while malware types describe how malicious software behaves or spreads.
Exam cue: Name the asset, threat, vulnerability and control when evaluating a scenario.
Concept 2
Layered protection combines identity, least privilege, encryption, filtering, backup, patching and user behaviour rather than relying on one control.
Exam cue: Explain what a safeguard protects and what residual risk remains.
Concept 3
Protocols define communication rules; FTP, HTTP and HTTPS serve different transfer purposes and security properties.
Exam cue: Separate encrypted web transport through HTTPS from authentication or the security of an endpoint.
Risk pitfalls and guardrails
Calling every cyber threat a virus.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Treating backup as prevention of unauthorised access.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Assuming HTTPS proves the information or organisation is trustworthy.
Guardrail: Keep to Northern Ireland CCEA scope, never add the weights of both routes, and distinguish a digital concept from unsupported product or technology claims.
Memory anchors
Malware
Software intentionally designed to disrupt, damage, spy or gain unauthorised access.
Phishing
Deceptive communication intended to obtain data or trigger unsafe action.
Firewall
A control filtering network traffic according to defined rules.
Encryption
Transforming readable data so authorised decryption is needed to understand it.
Protocol
An agreed set of rules for communication between systems.
HTTPS
HTTP carried through an encrypted and authenticated transport connection.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
