VCE Cyber Security

VCE Applied Computing Unit 2 Outcome 2 — Cyber Security — is where students learn how real organisations protect their networks, data and users from digital threats, and the legal frameworks that govern how that protection has to work in practice. It covers network hardware, security software, communication technologies, the threats organisations actually face, and the cryptography underneath modern security controls.

This is Cloodit's free worksheet set for VCE Applied Computing Unit 2 Outcome 2: 74 modules covering emerging cyber security trends, core network hardware (routers, switches, firewalls), security software (antivirus, intrusion detection and prevention, AI-based network security), communications technologies (wired, wireless, mobile, VPNs, LANs and WANs), the threat landscape (malware, ransomware, denial-of-service attacks, weak passwords and credential management), cyber security controls (encryption, multi-factor authentication, backup strategies, patching), cryptography from the Caesar cipher through to AES, RSA, ECDH and ECDSA, the Essential Eight and the Information Security Manual, and the Australian and Victorian privacy legislation that applies to how organisations must handle data. Each module includes real practice questions, worked examples, and a full answer key.

The modules are ordered to follow the outcome's own structure, so a student can work through them start to finish and build up exactly the knowledge this outcome assesses. Teachers can also assign these modules as a structured course — see the Cyber Security journey below — with progress tracking, class sprints, and badges for students.

Whether you're a VCE Applied Computing student revising for an outcome task, a teacher looking for ready-made worksheets with answer keys, or brushing up on one specific control or cipher, start with any module below or work straight through the full sequence.

Add this whole curriculum to your class, or just the modules your unit needs — Cloodit tracks who's stuck automatically.

29
Spyware Malware that secretly monitors a user's activity and collects information without their knowledge or consent
30
Viruses Malware that attaches to a host file and spreads by replicating itself when a user runs the infected file
31
Worms Malware that spreads by replicating itself across a network without needing a host file or user action
32
Ransomware Malware that encrypts or locks a victim's files and demands payment to restore access
33
Denial of service attacks An attack that floods a target with traffic, overwhelming its resources and blocking legitimate users
34
Improper credential management When passwords, keys or tokens are stored, shared or reused insecurely, letting attackers steal them and gain unauthorised access.
35
Outdated versions of software Software that hasn't been updated with the latest security patches, leaving known vulnerabilities open for attackers to exploit.
36
Weak passwords A password that is short, common, or predictable, making it easy for attackers to guess or crack.
37
Multi-factor authentication A login method that requires two or more independent proofs of identity, such as a password plus a one-time code.
38
Application of firmware Installing the latest low-level software on a hardware device to patch known security vulnerabilities.
39
Backup strategies A plan for how and when backups are taken and stored, such as scheduling regular backups and keeping copies in multiple locations.

Operating system updates Installing the latest patches for the OS, fixing known security vulnerabilities and bugs.
41
Software malware updates Refreshing the database used by security software so it can recognise and detect newly discovered threats.
42
Staff procedures A documented rule employees must follow, such as reporting incidents or locking devices, to reduce cyber security risk.
43
Encryption and decryption Turning a readable message into a scrambled, unreadable message using a key, so it can only be read again with decryption.
44
Caesar cipher A cipher that encrypts a message by shifting each letter forward by a fixed number, and decrypts it by shifting each letter back by the same number.
45
Polyalphabetic ciphers A cipher that uses a repeating list of shift numbers, so different letters in a message are shifted by different amounts.
46
Vigenere cipher A cipher that uses a keyword, where each keyword letter sets a different shift for the matching letter of the message.
47
Symmetric encryption Using the exact same secret key to both lock and unlock a message.
48
AES A widely used method of symmetric encryption that uses one shared key, which can be 128, 192, or 256 bits long, to lock and unlock data.
49
Asymmetric encryption Encryption that uses a linked pair of keys: a public key to encrypt data and a private key to decrypt it, with no shared secret key needed.
50
RSA A way of locking and unlocking messages using two matching keys: a public key anyone can have, and a private key kept secret by its owner.
51
ECDH A method where two people each combine their own secret with the other's shared piece, ending up with the same matching result without sending the secret.
52
ECDSA A digital signature algorithm that uses a private key to sign a message and the matching public key to verify it.
53
Machine learning analysis of network traffic Using a trained model to classify network traffic as normal or anomalous, based on learned patterns rather than fixed rules.
54
Real-time monitoring and notification Continuously checking network activity as it happens and immediately alerting the right people when a threat is detected.
55
Ethical hacking Authorised testing of a system to find security vulnerabilities before malicious attackers can exploit them.
