Cybersecurity Review

  ✅ PART 1: Satisfaction Survey Design (4–5 marks) What examiners want: A well-structured survey with clear formatting A mix of quantitative and qualitative questions Questions that assess security, usability, and performance Defined rating scales and response options Your plan: Title : “Longstaff Marketing Solutions Post-Project Satisfaction Survey” Intro : Brief explanation of purpose (e.g., “We’d like your feedback on recent system upgrades to help us improve future projects.”) Question types : Rating scales (e.g., 1–5 for clarity, security confidence, satisfaction) Multiple choice (e.g., “How do you access files?”) Open-ended (e.g., “What challenges are you still experiencing?”) Ranking (e.g., “Rank the IT issues you face most often”) Key topics to cover: Ease of access to resources Confidence in cyber security Training and guidance received Remote access experience (speed, reliability, ease) Shared account issues Impact of new router/firewall Overall satisfaction ✅ PART ...

 INTRODUCTION Longstaff Marketing Solutions is a fast-growing marketing agency which has recently  moved from its original home office to a new city centre office within business centre.  They have recently been major growth in the organization, with staff increasing to 25  employees in the past year. Most of the equipment from the older home office has  been moved to the newer office which forms the basis of the network. Currently, the  organization has a single virtual private network server, however it uses features  from its small office and home office network (SOHO) router provided by the internet  service providers (IPS). The same router is used to protect the network through its  implemented firewall. At the moment there are many key issues that affect the  organizations connectivity and compatibility issues. Many of these include: - SOHO router: They can pose several security concerns, including security  vulnerabilities, l...

 Executive Summary SkyLink Financial Systems Ltd is currently experiencing network performance issues, security vulnerabilities and poor remote access control due to an outdated and unstructured network design. With the organisation planning to expand from 220 employees to significantly more over the next five years, a modernised and scalable network infrastructure is essential. This proposal identifies the key causes of the existing connectivity problems, evaluates the associated cyber security risks, and provides a fully costed, secure network redesign. The proposed solution introduces network segmentation, modern firewall appliances, a cloud-based identity and access management system (Azure AD), an upgraded VPN platform, and infrastructure capable of supporting both business growth and secure remote access for Drone Display teams. The proposal also includes cyber-security mitigations, updated policy requirements, and costed investments in hardware, software, and cloud licensing...

 Task 3  Alongside the main assessment evidence (a project proposal that includes a network topology diagram), task 3  also assesses mathematics skills. The AO4 mathematics skills Mark Scheme is detailed after task 3. Note: tasks 2, 3 and 4 also assess English skills holistically. The AO4 English skills Mark Scheme is detailed after  task 4, though it may be useful to refer to the Mark Scheme whilst assessing the tasks to support an appropriate,  holistic judgement Band Mark Descriptor 5 20 to 24 The student provides a response to the task that: • demonstrates an excellent understanding of network connectivity issues (in relation  to the scenario of the brief) that is comprehensive and highly detailed • demonstrates an excellent understanding of how to resolve network connectivity  issues and address business needs (in relation to the scenario of the brief) that is  comprehensive and highly detailed • makes judgements on the equipment, software an...

Executive summary SkyLink must replace ad-hoc, under‑spec domestic networking with a secure, segmented, resilient architecture that protects intellectual property (drone displays), enforces least privilege, supports remote Drone Display teams, and scales for rapid growth. Recommended solution: enterprise router + managed switch(es), firewall with segmentation and high-availability, hardened on‑premises directory and file services integrated with cloud identity and file services (Azure AD + Microsoft 365 Business Premium + SharePoint/OneDrive), device management (Intune), endpoint protection, and a zero‑trust remote access model for Drone teams. This proposal includes an annotated network topology, security mitigations, rollout and testing plan, incident processes, staff training, and costed estimates with clear calculations to support AO4 mathematics and top‑band grading. Proposed network topology (annotated) Key features shown and explained below: Separate physical network for s...
