Firewall rule optimisation is the process of reviewing and improving the set of rules that control network traffic through a firewall. The aim is to make these rules more efficient, organised, and effective at protecting a network. This can involve removing duplicate or unused rules, reordering rules for better performance, and ensuring that only necessary…

BGP Security Mechanisms
BGP Security Mechanisms are methods and tools used to protect the Border Gateway Protocol, which helps route internet traffic between different networks. These mechanisms aim to prevent attacks or mistakes that could reroute, block, or intercept data. Common techniques include filtering, authentication, monitoring, and the use of cryptographic tools to ensure only trusted updates are…
Virtual Private Network Tunneling
Virtual Private Network (VPN) tunneling is a method of securely sending information over the internet by creating a protected path, or tunnel, between your device and another network. This tunnel hides your data from others so that it cannot be easily read or intercepted. VPN tunneling is commonly used to keep online activities private and…
Disaster Recovery as a Service (DRaaS)
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…
