Page 2: Checklist for 1.4
The page outlines the key areas covered in the OCR GCSE Computer Science 1.4 attacks and prevention section. It includes forms of attack, identifying vulnerabilities, and preventing attacks/vulnerabilities. This checklist serves as a roadmap for students studying this topic.
Highlight: The checklist covers three main areas: forms of attack, identifying vulnerabilities, and prevention methods.

Page 3: Specification Details
This page details the specific requirements from the OCR GCSE Computer Science specification for section 1.4. It covers forms of attack such as malware, social engineering, brute-force attacks, denial of service attacks, data interception and theft, and SQL injection. The page also outlines common prevention methods and the required knowledge for each topic.
Vocabulary: SQL injection - A type of cyber attack where malicious SQL statements are inserted into application queries to manipulate the database.
Example: Phishing is given as an example of social engineering, highlighting people as the 'weak point' in system security.

Page 4: Key Definitions
This page introduces the concept of key definitions, setting the stage for the detailed explanations that follow in subsequent pages. It emphasizes the importance of understanding fundamental terms in network security threats and solutions.

Page 5: Definition of Attack
This page provides a concise definition of an attack in the context of computer security. An attack is described as an attempt to access, edit, or delete data from a computer or network without authorization.
Definition: Attack - Trying to access/edit/delete data from a computer or network without proper authorization.

Page 6: Penetration Testing
The concept of penetration testing is explained on this page. It is defined as the practice of hiring a third-party to check a network or computer for vulnerabilities, which is a crucial aspect of physical security in computer science.
Definition: Penetration Testing - Hiring a third-party to check a network/computer for vulnerabilities.

Page 7: Firewall
This page defines a firewall and its function in network security. A firewall is described as a security measure that blocks certain IPs from accessing specific websites, playing a crucial role in network security threats and solutions.
Definition: Firewall - Blocks certain IPs from certain websites.

Page 8: Encryption
The concept of encryption is explained on this page. It is defined as using a unique secret code to ensure that files sent over the internet cannot be understood by unauthorized parties. Only the sender and recipient have the decryption key.
Definition: Encryption - Using a unique secret code to ensure the files sent over the internet cannot be understood. Only sender and recipient have the de-encryption key.

Page 9: Anti-Malware
This page defines anti-malware software and its role in computer security. It is described as software that regularly checks a network or computer for any malware present and removes it if detected.
Definition: Anti-Malware - Software that regularly checks a network/computer for any malware present and removes it if there is.

Page 10: User Access Levels
The concept of user access levels is explained on this page. It describes how users are grouped on a network, with each group having different access levels. This is an important aspect of software-based security methods in computer science.
Example: Senior staff members may have administrator level access.

Page 11: Physical Security
This page focuses on physical security measures in computer systems. It mentions examples such as locking doors, using CCTV, and employing security guards as part of physical security in GCSE Computer Science OCR.
Definition: Physical Security - Locking doors, CCTV, Security Guards.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
