Network threat modelling is the process of identifying and evaluating potential security risks to a computer network. It involves mapping out how data and users move through the network, then looking for weak points where attackers could gain access or disrupt services. The goal is to understand what threats exist and prioritise defences before problems…
Real-Time Threat Monitoring is the process of continuously watching computer systems, networks, or applications for signs of possible security threats or malicious activity as they happen. It uses automated tools to detect and alert security teams about suspicious behaviour or unauthorised access attempts without delay. This helps organisations respond quickly to security incidents and minimise…
Zero Trust Network Segmentation is a security approach that divides a computer network into smaller zones, requiring strict verification for any access between them. Instead of trusting devices or users by default just because they are inside the network, each request is checked and must be explicitly allowed. This reduces the risk of attackers moving…
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…
Secure DNS Resolution refers to the process of safely translating website names into their corresponding IP addresses, ensuring that the information cannot be tampered with or intercepted by attackers. Traditional DNS lookups are vulnerable to eavesdropping and manipulation, which can lead users to malicious websites without their knowledge. Secure DNS methods use encryption and verification…
Network flow monitoring is the process of collecting and analysing information about data traffic as it moves through a computer network. It tracks details such as which devices are communicating, how much data is being transferred, and which protocols are being used. This monitoring helps organisations understand how their networks are being used, identify unusual…
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 (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…
Secure Socket Layer Inspection, often called SSL inspection, is a process used by security devices to examine encrypted internet traffic. Normally, data sent over HTTPS is encrypted to keep it private, which also hides it from security tools. SSL inspection temporarily decrypts this traffic so the device can check it for threats like viruses or…
Network Access Control Policies are rules set by organisations to decide who can connect to their computer networks and what resources they can use. These policies help keep networks safe by allowing only trusted devices and users to access sensitive information. They can be based on user identity, device type, location, or time of access,…
