📌 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

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.

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.

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.

💡Other Useful Knowledge Cards

Department Hub

A Department Hub is a centralised online space where all resources, information, and tools related to a specific department are organised and easily accessible. It serves as a one-stop location for team members to find documents, announcements, contacts, and key processes relevant to their work. Department Hubs help improve communication, collaboration, and efficiency by keeping everything a team needs in one place.

Cloud-Native Development

Cloud-native development is a way of building and running software that is designed to work well in cloud computing environments. It uses tools and practices that make applications easy to deploy, scale, and update across many servers. Cloud-native apps are often made up of small, independent pieces called microservices, which can be managed separately for greater flexibility and reliability.

Data Provenance in Analytics

Data provenance in analytics refers to the process of tracking the origins, history and movement of data as it is collected, transformed and used in analysis. It helps users understand where data came from, what changes it has undergone and who has handled it. This transparency supports trust in the results and makes it easier to trace and correct errors or inconsistencies.

Data Quality Monitoring

Data quality monitoring is the ongoing process of checking and ensuring that data used within a system is accurate, complete, consistent, and up to date. It involves regularly reviewing data for errors, missing values, duplicates, or inconsistencies. By monitoring data quality, organisations can trust the information they use for decision-making and operations.

OAuth 2.1 Enhancements

OAuth 2.1 is an update to the OAuth 2.0 protocol, designed to make online authentication and authorisation safer and easier to implement. It simplifies how apps and services securely grant users access to resources without sharing passwords, by clarifying and consolidating security best practices. OAuth 2.1 removes outdated features, mandates the use of secure flows, and requires stronger protections against common attacks, making it less error-prone for developers.
