Data recovery protocols are organised procedures and methods used to retrieve lost, deleted or corrupted digital information from various storage devices. These protocols guide how to act when data loss occurs, helping ensure that as much information as possible can be restored safely and efficiently. They often include steps for assessing the damage, selecting recovery…

Secure Backup Strategies
Secure backup strategies involve creating copies of important data and storing them in a way that protects against loss, theft, or damage. These methods ensure that information can be recovered if the original data is lost due to accidents, hardware failure, cyber-attacks, or natural disasters. Good strategies use encryption, regular updates, and off-site or cloud…
Key Ceremony Processes
Key ceremony processes are carefully organised procedures used to generate, distribute, and manage cryptographic keys in secure systems. These ceremonies are designed to ensure that no single person has complete control over the keys and that all steps are transparent and auditable. They often involve multiple participants, secure environments, and detailed documentation to prevent unauthorised…
Public Key Infrastructure (PKI)
Public Key Infrastructure, or PKI, is a set of technologies and rules that help keep digital communications secure. It uses a system of digital certificates and encryption to verify the identity of people, devices, or websites. PKI makes sure that the information sent online is private and has not been changed by anyone else
Digital Certificate Management
Digital certificate management is the process of handling digital certificates, which are electronic credentials used to verify the identity of users, devices, or organisations online. It involves creating, distributing, renewing, and revoking certificates to ensure secure communication and data exchange. Proper management helps prevent expired or compromised certificates from causing security risks.
Message Authentication Codes
Message Authentication Codes, or MACs, are short pieces of information used to check that a message really comes from the sender and has not been changed along the way. They use a secret key shared between the sender and receiver to create a unique code for each message. If even a small part of the…
Secure Hash Algorithms
Secure Hash Algorithms, often shortened to SHA, are a family of mathematical functions that take digital information and produce a short, fixed-length string of characters called a hash value. This process is designed so that even a tiny change in the original information will produce a completely different hash value. The main purpose of SHA…
Entropy Pool Management
Entropy pool management refers to the way a computer system collects, stores, and uses random data, known as entropy, which is essential for creating secure cryptographic keys and random numbers. Systems gather entropy from various unpredictable sources, such as mouse movements, keyboard timings, or hardware events, and mix it into a pool. This pool is…
Secure Random Number Generation
Secure random number generation is the process of creating numbers that are unpredictable and suitable for use in security-sensitive applications. Unlike regular random numbers, secure random numbers must resist attempts to guess or reproduce them, even if someone knows how the system works. This is essential for tasks like creating passwords, cryptographic keys, and tokens…
Cryptographic Agility
Cryptographic agility is the ability of a system or application to quickly and easily switch between different cryptographic algorithms or protocols. This flexibility is important because older algorithms can become insecure over time as new vulnerabilities are discovered. By designing systems with cryptographic agility, organisations can update their security measures without having to rebuild or…
