A Trusted Execution Environment (TEE) is a secure area within a main processor that ensures sensitive data and code can be processed in isolation from the rest of the system. This means that even if the main operating system is compromised, the information and operations inside the TEE remain protected. TEEs are designed to prevent…

Secure Boot
Secure Boot is a security feature that ensures a device only runs software that is trusted by its manufacturer. When a computer starts up, Secure Boot checks each piece of software, such as the operating system and drivers, against a list of approved signatures. If the software has not been approved or has been tampered…
Byzantine Fault Tolerance
Byzantine Fault Tolerance is a property of computer systems that allows them to keep working correctly even if some parts fail or act unpredictably, including being malicious or sending incorrect information. It is particularly important in distributed systems, where multiple computers or nodes must agree on a decision even if some are unreliable. The term…
Secure Coding Practices
Secure coding practices are a set of guidelines and techniques used by software developers to write code that protects applications from security threats. These practices help to prevent vulnerabilities, such as data leaks, unauthorised access, or malicious attacks, by making sure the code is robust and safe. Developers follow secure coding practices throughout the software…
File Integrity Monitoring (FIM)
File Integrity Monitoring (FIM) is a security process that checks and tracks changes to files on a computer system or network. It helps ensure that important files, such as system configurations or sensitive data, are not changed without authorisation. FIM tools alert administrators if files are modified, deleted, or added unexpectedly, helping to detect potential…
Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) is a security process that requires users to provide two or more independent credentials to verify their identity. These credentials typically fall into categories such as something you know, like a password, something you have, such as a phone or security token, and something you are, like a fingerprint or facial recognition….
Brute Force Protection
Brute force protection is a set of measures used to stop attackers from repeatedly guessing passwords or access codes in an attempt to break into an account or system. It works by detecting and limiting repeated failed login attempts, often by locking accounts or introducing delays after several wrong tries. These methods help keep information…
Network Segmentation
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.
Ransomware Containment
Ransomware containment refers to the steps taken to stop ransomware from spreading to other computers or systems once it has been detected. This process aims to limit damage by isolating infected devices, cutting off network access, and preventing further files from being encrypted. Effective containment helps organisations recover more quickly and reduces the risk of…
Malware Sandbox
A malware sandbox is a secure, isolated digital environment where suspicious files or programmes can be run and observed without risking the safety of the main computer or network. It allows security professionals to analyse how potentially harmful software behaves, looking for signs of malicious activity like stealing data or damaging files. By using a…
