A Web Application Firewall (WAF) is a security system that monitors, filters, and blocks harmful traffic to and from web applications. It acts as a protective barrier between a website and the internet, helping to stop attacks such as SQL injection, cross-site scripting, and other common threats. By analysing incoming and outgoing web requests, a…

Browser Isolation
Browser isolation is a security technique that separates web browsing activity from the rest of a computer or network. It works by running browser sessions in a secure, isolated environment, often on a remote server or a virtual machine. This way, if a user visits a malicious website, any harmful code or malware is contained…
Certificate Transparency
Certificate Transparency is a system that helps make digital certificates, which secure websites, more open and trustworthy. It works by publicly logging every certificate issued, so anyone can check for mistakes or unauthorised certificates. This helps prevent attackers from creating fake certificates to impersonate websites and improves overall trust in internet security.
Secure File Transfer
Secure file transfer refers to the process of sending files from one device or location to another in a way that protects the contents from unauthorised access or tampering. This is usually achieved by using encryption, which scrambles the data so only the intended recipient can read it. Secure file transfer methods also ensure that…
Content Security Policy (CSP)
Content Security Policy (CSP) is a security feature in web browsers that helps prevent malicious scripts and other harmful content from running on websites. It works by letting website owners specify which sources of content are allowed to be loaded, such as images, scripts, and stylesheets. By setting these rules, CSP can stop many types…
Network Traffic Analysis
Network traffic analysis is the process of monitoring, capturing, and examining data packets as they travel across a computer network. This helps identify patterns, detect unusual activity, and ensure that the network is running smoothly. It is used by IT professionals to troubleshoot problems, improve performance, and enhance security by spotting threats or unauthorised access.
Honeypot Deployment
Honeypot deployment refers to setting up a decoy computer system or network service designed to attract and monitor unauthorised access attempts. The honeypot looks like a real target but contains no valuable data, allowing security teams to observe attacker behaviour without risking genuine assets. By analysing the interactions, organisations can improve their defences and learn…
Front-Running Mitigation
Front-running mitigation refers to methods and strategies used to prevent or reduce the chances of unfair trading practices where someone takes advantage of prior knowledge about upcoming transactions. In digital finance and blockchain systems, front-running often happens when someone sees a pending transaction and quickly places their own order first to benefit from the price…
DNS Tunneling
DNS tunnelling is a technique that uses the Domain Name System (DNS) protocol to transfer data that is not usually allowed by network restrictions. It works by encoding data inside DNS queries and responses, which are typically allowed through firewalls since DNS is essential for most internet activities. This method can be used for both…
Session Fixation
Session fixation is a type of security vulnerability where an attacker tricks a user into using a specific session ID. If the web application does not properly generate a new session ID after login, the attacker can gain access to the user’s session. This means the attacker can impersonate the user and access private information…
