Zero Trust Architecture is a security approach that assumes no user or device, inside or outside an organisation’s network, is automatically trustworthy. Every request to access resources must be verified, regardless of where it comes from. This method uses strict identity checks, continuous monitoring, and limits access to only what is needed for each user…

Access Control
Access control is a security technique that determines who or what can view or use resources in a computing environment. It sets rules that allow or block certain users from accessing specific information or systems. This helps protect sensitive data and prevents unauthorised use of resources.
Digital Signature
A digital signature is a secure electronic method used to verify the authenticity of a digital message or document. It proves that the sender is who they claim to be and that the content has not been altered since it was signed. Digital signatures rely on mathematical techniques and encryption to create a unique code…
Cryptographic Hash Function
A cryptographic hash function is a mathematical process that takes any amount of digital data and creates a fixed-size string of characters, which appears random. This process is designed so that even a small change in the original data will result in a completely different output. The function is also one-way, meaning it is practically…
Private Key Management
Private key management refers to the processes and tools used to securely store, use, and protect cryptographic private keys. These keys are critical for accessing encrypted data or authorising digital transactions, so their security is essential to prevent unauthorised access. Good private key management involves creating, storing, backing up, and eventually destroying private keys safely,…
Public Key Cryptography
Public key cryptography is a method for securing digital communication by using two different keys. One key is public and can be shared with anyone, while the other key is private and kept secret. Messages encrypted with the public key can only be decrypted with the matching private key, ensuring that only the intended recipient…
Identity Verification
Identity verification is the process of confirming that a person is who they claim to be. This often involves checking official documents, personal information, or using digital methods like facial recognition. The goal is to prevent fraud and ensure only authorised individuals can access certain services or information. Reliable identity verification protects both businesses and…
Role-Based Access
Role-Based Access is a method for controlling who can see or use certain parts of a system or data. It works by assigning people to roles, and each role has its own set of permissions. This helps organisations manage security and privacy, making sure that only the right people have access to sensitive information or…
Access Control Management
Access control management is the process of deciding who can use or view certain resources, data, or areas within a system, building, or network. It involves setting up rules and systems that determine which users have permission to perform specific actions, such as reading, editing, or deleting information. This helps organisations protect sensitive information and…
DevSecOps
DevSecOps is a way of working that brings together development, security, and operations teams to create software. It aims to make security a shared responsibility throughout the software development process, rather than something added at the end. By doing this, teams can find and fix security issues earlier and build safer applications faster.
