📌 Zero Trust Network Design Summary

Zero Trust Network Design is a security approach where no device or user is trusted by default, even if they are inside a private network. Every access request is verified, and permissions are strictly controlled based on identity and context. This method helps limit potential damage if a hacker gets inside the network, as each user or device must continuously prove they are allowed to access resources.

🙋🏻‍♂️ Explain Zero Trust Network Design Simply

Imagine a school where every student and teacher must show their ID card every time they enter a classroom, even if they have been there before. No one gets special access just because they are already inside the building. This way, it is much harder for someone who should not be there to go unnoticed or reach important areas.

📅 How Can it be used?

A company could implement Zero Trust by requiring employees to verify their identity before accessing sensitive files, even when working remotely.

🗺️ Real World Examples

A hospital uses Zero Trust Network Design by requiring doctors and nurses to use multi-factor authentication before accessing patient records. Even if someone manages to get onto the hospital’s internal network, they cannot view sensitive data without proving their identity and having the right permissions.

A financial services firm sets up Zero Trust by segmenting its network and only allowing access to trading systems for staff who have passed strict security checks, ensuring that even if a device is compromised, it cannot access everything.

✅ FAQ

Zero Trust Network Design is a way of protecting computer systems by not automatically trusting anyone or anything, even if they are inside your organisation. Every person or device must prove who they are every time they ask to use a resource, like files or apps. This helps stop hackers from moving freely if they do manage to get in, limiting the damage they can cause.

With Zero Trust, access is always checked, no matter where you are or what device you are using. Instead of just logging in once and having access to everything, you will need to prove your identity and permissions more often. This means it is much harder for someone who should not be there to get hold of sensitive information, even if they are inside the company network.

Yes, Zero Trust Network Design is especially helpful for remote work. It checks every access request based on who you are, where you are, and what device you are using. This makes it much safer for people working from home or on the go, as it reduces the chances of someone sneaking in just because they are connected from outside the office.

Technology Adoption Framework

A Technology Adoption Framework is a structured approach that helps organisations or individuals decide how and when to start using new technologies. It outlines the steps, considerations, and factors that influence the successful integration of technology into daily routines or business processes. These frameworks often consider aspects like readiness, training, support, and measuring impact to ensure that technology delivers its intended benefits.

Application Rationalisation

Application rationalisation is the process of reviewing and evaluating an organisation's software applications to determine which should be kept, updated, replaced, or retired. This helps reduce unnecessary costs, complexity, and duplication by ensuring only the most valuable and effective applications are used. The goal is to streamline the technology environment, making it easier to manage and support.

Model Deployment Automation

Model deployment automation is the process of automatically transferring machine learning models from development to a live environment where they can be used by others. It involves using tools and scripts to handle steps like packaging the model, testing it, and setting it up on servers without manual work. This makes it easier, faster, and less error-prone to update or launch models in real applications.

Injection Mitigation

Injection mitigation refers to the techniques and strategies used to prevent attackers from inserting malicious code or data into computer systems, especially through user inputs. These attacks, often called injection attacks, can cause systems to behave in unintended ways, leak data, or become compromised. Common types of injection include SQL injection, command injection, and cross-site scripting, all of which exploit vulnerabilities in how user input is handled.

Cross-Site Scripting (XSS) Mitigation

Cross-Site Scripting (XSS) mitigation refers to the methods used to protect websites and applications from XSS attacks, where malicious scripts are injected into web pages viewed by other users. These attacks can steal data, hijack sessions, or deface websites if not properly prevented. Mitigation involves input validation, output encoding, proper use of security headers, and keeping software up to date.
