Disaster Recovery as a Service (DRaaS) is a cloud-based solution that helps organisations quickly recover their IT systems and data after an unexpected event, such as a cyberattack, hardware failure, or natural disaster. It works by securely copying critical data and applications to a remote location managed by a third-party provider. When a disaster occurs,…

Cloud-Native Security Models
Cloud-native security models are approaches to protecting applications and data that are built to run in cloud environments. These models use the features and tools provided by cloud platforms, like automation, scalability, and microservices, to keep systems safe. Security is integrated into every stage of the development and deployment process, rather than added on at…
Data Recovery Protocols
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…
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 Remote Access
Secure remote access is a way for people to safely connect to a computer system or network from a different location. It makes sure only authorised users can access sensitive data or services, even when they are not physically present. Security measures like encryption and authentication protect information from being intercepted or misused during the…
Software-Defined Perimeter (SDP)
A Software-Defined Perimeter (SDP) is a security approach that restricts network access so only authorised users and devices can reach specific resources. It works by creating secure, temporary connections between users and the services they need, making the rest of the network invisible to outsiders. This method helps prevent unauthorised access and reduces the risk…
Discretionary Access Control (DAC)
Discretionary Access Control, or DAC, is a method for managing access to resources like files or folders. It allows the owner of a resource to decide who can view or edit it. This approach gives users flexibility to share or restrict access based on their own preferences. DAC is commonly used in many operating systems…
Mandatory Access Control (MAC)
Mandatory Access Control, or MAC, is a security framework used in computer systems to strictly regulate who can access or modify information. In MAC systems, access rules are set by administrators and cannot be changed by individual users. This method is commonly used in environments where protecting sensitive data is crucial, such as government or…
Privileged Access Management
Privileged Access Management, or PAM, is a set of tools and practices used by organisations to control and monitor who can access important systems and sensitive information. It ensures that only authorised individuals have elevated permissions to perform critical tasks, such as changing system settings or accessing confidential data. By managing these special permissions, businesses…
