Application layer filtering is a security technique used to examine and control network traffic based on the specific applications or services being accessed. Unlike basic firewalls that only look at addresses and ports, application layer filters can inspect the actual content of messages, such as HTTP requests or email contents. This allows for more precise…

Network Access Control (NAC)
Network Access Control (NAC) is a security solution that manages which devices are allowed to connect to a computer network. It checks the identity and security status of devices before granting access, ensuring that only approved and compliant devices can use network resources. NAC can block, restrict, or monitor devices that do not meet the…
Patch Management
Patch management is the process of updating software, operating systems, or applications to fix security vulnerabilities, correct bugs, or improve performance. It involves identifying which patches are needed, obtaining and testing them, and then deploying them to devices or systems. Proper patch management helps organisations reduce the risk of cyber attacks and ensures their technology…
Secure Software Development Lifecycle
The Secure Software Development Lifecycle, or SSDLC, is a process for building software with security in mind from the very beginning. It includes planning, designing, coding, testing, and maintaining software, ensuring that security checks and practices are part of each stage. By following SSDLC, teams aim to prevent security problems before they happen, rather than…
Fault Injection Attacks
Fault injection attacks are deliberate attempts to disrupt the normal operation of electronic devices or computer systems by introducing unexpected changes, such as glitches in power, timing, or environmental conditions. These disruptions can cause the device to behave unpredictably, often bypassing security checks or revealing sensitive information. Attackers use fault injection to exploit weaknesses in…
Secure Session Management
Secure session management refers to the methods and practices used to keep user sessions safe when interacting with websites or applications. This includes creating, maintaining, and ending sessions in a way that prevents attackers from hijacking or impersonating users. Techniques such as using unique session identifiers, enforcing timeouts, and securely storing session data help protect…
Reverse Engineering
Reverse engineering is the process of taking apart a product, system, or software to understand how it works. This can involve analysing its structure, function, and operation, often with the goal of recreating or improving it. It is commonly used when original design information is unavailable or to check for security vulnerabilities.
Secure DevOps Pipelines
Secure DevOps pipelines are automated workflows for building, testing, and deploying software, with added security measures at every stage. These pipelines ensure that code is checked for vulnerabilities, dependencies are safe, and sensitive data is protected during development and deployment. The goal is to deliver reliable software quickly, while reducing the risk of security issues.
Chaos Engineering for Security
Chaos Engineering for Security is a method where organisations intentionally introduce controlled disruptions or failures to their systems to test and improve their security measures. By simulating attacks or unexpected events, teams can observe how their defences respond and identify weaknesses before real attackers do. This approach helps ensure that security systems are robust and…
Static Application Security Testing (SAST)
Static Application Security Testing (SAST) is a method used to find security flaws in software by analysing its source code, bytecode, or binary code without actually running the program. This process helps developers identify and fix vulnerabilities early in the development cycle, before the software is deployed. SAST tools scan the code for patterns that…
