📌 Web Application Firewall (WAF) Summary

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 WAF can prevent unauthorised access and keep sensitive data safe.

🙋🏻‍♂️ Explain Web Application Firewall (WAF) Simply

Imagine a security guard standing at the entrance of a building, checking everyone who comes in to make sure they are not carrying anything dangerous. A WAF does the same job for websites, examining all data that tries to enter or leave to make sure it is safe and allowed.

📅 How Can it be used?

A WAF can be set up to protect an online shop from hackers trying to steal customer information or disrupt services.

🗺️ Real World Examples

An e-commerce company uses a WAF to protect its website from cyber attacks during a busy sales event. The WAF automatically blocks suspicious requests that look like someone trying to steal credit card details or disrupt the checkout process, keeping the site running smoothly and protecting customer information.

A local council uses a WAF to shield its online services from attacks that aim to exploit weaknesses in its web forms. The firewall filters out attempts to inject malicious code, helping to ensure that residents can safely access services such as bill payments and appointment bookings.

✅ FAQ

A Web Application Firewall works like a security guard for your website. It checks every request coming in and going out, looking for anything suspicious or harmful. By blocking dangerous traffic, it helps keep your website and its visitors safe from common attacks like hackers trying to steal data or break in.

Websites are often targeted by attackers looking for weaknesses. A Web Application Firewall helps protect your site from threats that could lead to stolen information or downtime. It acts as a barrier, so you can worry less about cyber attacks and focus more on running your site smoothly.

While a Web Application Firewall is very effective at blocking many common threats, no security tool can catch absolutely everything. It is a strong first line of defence, but it works best when combined with other good security practices, like keeping your software up to date and using strong passwords.

Business Integration Playbook

A Business Integration Playbook is a structured guide that outlines the steps, best practices and tools for combining different business processes, systems or organisations. It helps companies ensure that their operations, technologies and teams work together smoothly after a merger, acquisition or partnership. This playbook typically covers planning, communication, managing change and measuring success to reduce risks and improve results.

Fraud Detection

Fraud detection is the process of identifying activities that are intended to deceive or cheat, especially for financial gain. It involves monitoring transactions, behaviours, or data to spot signs of suspicious or unauthorised actions. By catching fraudulent actions early, organisations can prevent losses and protect customers.

Adversarial Example Defense

Adversarial example defence refers to techniques and methods used to protect machine learning models from being tricked by deliberately altered inputs. These altered inputs, called adversarial examples, are designed to look normal to humans but cause the model to make mistakes. Defences help ensure the model remains accurate and reliable even when faced with such tricky inputs.

Kerberos Exploitation

Kerberos exploitation refers to techniques used by attackers to abuse weaknesses or misconfigurations in the Kerberos authentication protocol. Kerberos is widely used in Windows environments to manage secure logins and resource access. Attackers can exploit vulnerabilities to gain unauthorised access, impersonate users, or escalate their privileges within a network.

Penetration Testing Framework

A penetration testing framework is a structured set of guidelines, tools and processes used to plan and carry out security tests on computer systems, networks or applications. It provides a consistent approach for ethical hackers to identify vulnerabilities by simulating attacks. This helps organisations find and fix security weaknesses before malicious attackers can exploit them.
