📌 Network Segmentation Summary
Network segmentation is the practice of dividing a computer network into smaller, isolated sections. Each segment can have its own security rules and access controls, which helps limit the spread of threats and improves performance. By separating sensitive systems from general traffic, organisations can better manage who has access to what.
🙋🏻♂️ Explain Network Segmentation Simply
Imagine a school where students from different year groups are in separate classrooms with locked doors. If someone causes trouble in one room, it does not affect the others. Network segmentation works like those locked doors, keeping different parts of a computer network apart so problems in one area do not spread elsewhere.
📅 How Can it be used?
Segmenting the office network can keep staff computers separate from servers, reducing the risk of malware spreading.
🗺️ Real World Examples
A hospital uses network segmentation to keep medical equipment and patient data systems on separate networks from staff Wi-Fi. This ensures that if the guest Wi-Fi is compromised, critical medical systems are still protected from unauthorised access.
A retail store separates its payment processing systems from its public customer Wi-Fi. This helps protect credit card transactions and customer information, even if the public Wi-Fi is attacked or misused.

Cloud Workload Optimization
Cloud workload optimisation is the process of making sure that applications and tasks running in a cloud environment use resources efficiently. This includes managing how much computing power, storage, and network capacity each workload needs, so that costs are kept low and performance stays high. By monitoring and adjusting resources as needed, organisations avoid waste and make the most of their cloud investment.
Incident Response Playbooks
Incident response playbooks are step-by-step guides that organisations use to handle security incidents, such as cyber attacks or data breaches. They outline the actions to take, who is responsible, and how to communicate during and after an incident. Playbooks help teams respond quickly and consistently, reducing the impact of threats and speeding up recovery.
Net Promoter Score Framework
The Net Promoter Score Framework is a method used by organisations to measure customer loyalty and satisfaction. It involves asking customers how likely they are to recommend a company, product, or service to others on a scale from 0 to 10. The responses are then grouped into three categories: promoters, passives, and detractors, which help companies understand their overall customer sentiment and identify areas for improvement.
Learning Management System
A Learning Management System (LMS) is a software platform used to deliver, track, and manage educational courses or training programmes. It allows teachers or trainers to create and share lessons, assign tasks, conduct assessments, and monitor student progress all in one place. LMSs are commonly used by schools, universities, and businesses to organise learning activities and provide online access to educational content.
Policy Iteration Techniques
Policy iteration techniques are methods used in reinforcement learning to find the best way for an agent to make decisions in a given environment. The process involves two main steps: evaluating how good a current plan or policy is, and then improving it based on what has been learned. By repeating these steps, the technique gradually leads to a policy that achieves the best possible outcome for the agent. These techniques are commonly used for solving decision-making problems where outcomes depend on both current choices and future possibilities.
