📌 Zero Trust Network Segmentation Summary
Zero Trust Network Segmentation is a security approach that divides a computer network into smaller zones, requiring strict verification for any access between them. Instead of trusting devices or users by default just because they are inside the network, each request is checked and must be explicitly allowed. This reduces the risk of attackers moving freely within a network if they manage to breach its defences.
🙋🏻♂️ Explain Zero Trust Network Segmentation Simply
Imagine a school where every classroom is locked and students need a special pass to enter each room, even if they are already inside the building. This way, if someone sneaks in, they cannot just wander everywhere without being stopped. Zero Trust Network Segmentation works like those locked doors, making sure only the right people can get into each part of the network.
📅 How Can it be used?
Zero Trust Network Segmentation can limit application access in a cloud environment, ensuring only authorised services communicate with each other.
🗺️ Real World Examples
A hospital uses Zero Trust Network Segmentation to separate patient records, medical devices, and staff computers into distinct zones. Only authorised staff can access patient records, and even if a device is compromised, attackers cannot move directly to other sensitive areas.
A financial services company segments its internal network so that the accounting department, customer support, and development teams have isolated access. This ensures a breach in one department does not allow unauthorised access to sensitive financial data in another.
✅ FAQ
What is Zero Trust Network Segmentation and why is it useful?
Zero Trust Network Segmentation is a way of organising a computer network into smaller, separate sections, where every attempt to move between these sections is checked and must be approved. This is helpful because it makes it much harder for attackers to spread through a network if they get in. By not automatically trusting anyone or anything inside the network, it adds an extra layer of security and helps protect important information.
How does Zero Trust Network Segmentation differ from traditional network security?
Traditional network security often assumes that anything inside the network can be trusted, so once someone gets in, they can move around quite freely. Zero Trust Network Segmentation changes this by treating every access request as suspicious, even if it comes from inside. This means that every device and user has to prove they are allowed to do what they are trying to do, making it much harder for threats to spread.
Can Zero Trust Network Segmentation help protect against ransomware?
Yes, Zero Trust Network Segmentation can be very helpful against ransomware. By breaking up the network into smaller zones and requiring strict checks for every move between them, it becomes much more difficult for ransomware to spread quickly. If ransomware does get into one part of the network, these barriers can stop it from reaching other important systems and data.

On-Policy Reinforcement Learning
On-policy reinforcement learning is a method where an agent learns to make decisions by following and improving the same policy that it uses to interact with its environment. The agent updates its strategy based on the actions it actually takes, rather than exploring alternative possibilities. This approach helps the agent gradually improve its behaviour through direct experience, using feedback from the outcomes of its own choices.
Requirements Engineering
Requirements engineering is the process of identifying, documenting, and managing what a system or product must do to meet the needs of its users and stakeholders. It involves gathering information from everyone involved, understanding their needs, and turning those into clear, agreed-upon statements about what the system should achieve. This helps ensure that the final product does what is needed and avoids costly changes later.
Competitive Multi-Agent Systems
Competitive multi-agent systems are computer-based environments where multiple independent agents interact with each other, often with opposing goals. Each agent tries to achieve its own objectives, which may conflict with the objectives of others. These systems are used to study behaviours such as competition, negotiation, and strategy among agents. They are commonly applied in areas where decision-making entities must compete for resources, outcomes, or rewards.
Knowledge Injection Frameworks
Knowledge injection frameworks are software tools or systems that help add external information or structured knowledge into artificial intelligence models or applications. This process improves the model's understanding and decision-making by providing data it might not learn from its training alone. These frameworks manage how, when, and what information is inserted, ensuring consistency and relevance.
Network Security
Network security is the practice of protecting computer networks from unauthorised access, misuse, or attacks. It involves using tools, policies, and procedures to keep data and systems safe as they are sent or accessed over networks. The aim is to ensure that only trusted users and devices can use the network, while blocking threats and preventing data leaks.
