Broadcast encryption is a method that allows a broadcaster to send encrypted information so that only specific, authorised users can decrypt and access it. This technique is often used when a message needs to be sent to a group, but not everyone should be able to read it. The broadcaster manages keys so that only…
A Secure API Gateway is a tool or service that acts as a checkpoint between users and backend services, filtering and managing all requests to APIs. It helps protect sensitive data by enforcing security policies, authentication, and rate limiting, ensuring only authorised users can access certain resources. Secure API Gateways also provide monitoring and logging…
Application layer filtering is a security technique used to examine and control network traffic based on the specific applications or services being accessed. Unlike basic firewalls that only look at addresses and ports, application layer filters can inspect the actual content of messages, such as HTTP requests or email contents. This allows for more precise…
Network Access Control (NAC) is a security solution that manages which devices are allowed to connect to a computer network. It checks the identity and security status of devices before granting access, ensuring that only approved and compliant devices can use network resources. NAC can block, restrict, or monitor devices that do not meet the…
Transport Layer Security (TLS) optimisation refers to the process of improving the speed and efficiency of secure connections over the internet while maintaining strong security. It involves techniques such as reducing handshake times, reusing session data, and choosing faster cryptographic algorithms. The goal is to make encrypted communications as fast and seamless as possible for…
Cross-Origin Resource Sharing (CORS) is a security feature used by web browsers to control how resources on one website can be requested from another domain. It helps prevent malicious websites from accessing sensitive information on a different site without permission. CORS works by using special HTTP headers set by the server to specify which external…
OAuth token revocation is a process that allows an application or service to invalidate an access token or refresh token before it would normally expire. This ensures that if a token is compromised or a user logs out, the token can no longer be used to access protected resources. Token revocation helps improve security by…
Protocol fuzzing is a method used to test the security and reliability of communication protocols by automatically sending large amounts of random or unexpected data to them. This helps uncover hidden bugs, vulnerabilities, or weaknesses that might not be found through regular testing. By exposing how a protocol handles unusual input, developers can fix problems…
Container security refers to the set of practices and tools designed to protect software containers, which are lightweight, portable units used to run applications. These measures ensure that the applications inside containers are safe from unauthorised access, vulnerabilities, and other threats. Container security covers the whole lifecycle, from building and deploying containers to running and…
A Cloud Access Security Broker (CASB) is a software tool or service that sits between users and cloud service providers to monitor and control data traffic. It helps organisations enforce security policies, protect data, and ensure compliance when employees access cloud applications. CASBs provide visibility into cloud usage, detect risky behaviour, and can block unauthorised…
