📌 Dynamic Application Security Testing (DAST) Summary

Dynamic Application Security Testing (DAST) is a method of testing the security of a running application by simulating attacks from the outside, just like a hacker would. It works by scanning the application while it is operating to find vulnerabilities such as broken authentication, insecure data handling, or cross-site scripting. DAST tools do not require access to the application’s source code, instead interacting with the application through its user interface or APIs to identify weaknesses that could be exploited.

🙋🏻‍♂️ Explain Dynamic Application Security Testing (DAST) Simply

Imagine checking a locked door by trying to open it, pick the lock, or see if the windows are left open instead of just looking at the blueprint. DAST works in a similar way by actively probing a live application for security gaps rather than just reviewing its plans.

📅 How Can it be used?

DAST can be used to automatically scan a web application for vulnerabilities before it is released to users.

🗺️ Real World Examples

An e-commerce company uses DAST tools to scan their online shop during development and before each major update. The tool identifies a vulnerability where customer data could be exposed through a specific URL, allowing the security team to fix the issue before customers are put at risk.

A bank integrates DAST into its software development pipeline to automatically test each new version of its online banking portal. This helps catch and address security flaws related to user authentication and transaction processing before the website goes live.

✅ FAQ

Dynamic Application Security Testing, or DAST, is a way to check how secure an application is while it is running. It works by simulating real-life attacks, much like a hacker would, to spot weaknesses such as poor authentication or unsafe data handling. The process does not involve looking at the code itself but instead tests the application through its interface or APIs to find any security gaps.

DAST helps businesses find security problems that could be missed if only the code is reviewed. Since it tests the application as it runs, DAST can uncover issues that only appear during real use. This means businesses can fix vulnerabilities before attackers find them, making their applications safer for users.

DAST is very effective at finding certain types of security problems, especially those that can be exploited from outside the application, like broken authentication or cross-site scripting. However, it may not spot issues hidden deep in the code or problems that do not show up during normal use. For full coverage, it is often used alongside other security testing methods.

Multi-Party Model Training

Multi-Party Model Training is a method where several independent organisations or groups work together to train a machine learning model without sharing their raw data. Each party keeps its data private but contributes to the learning process, allowing the final model to benefit from a wider range of information. This approach is especially useful when data privacy, security, or regulations prevent direct data sharing between participants.

Deepfake Mitigation Techniques

Deepfake mitigation techniques are methods and tools designed to detect, prevent, or reduce the impact of fake digital media, such as manipulated videos or audio recordings. These techniques use a mix of computer algorithms, digital watermarking, and human oversight to spot and flag artificial content. Their main goal is to protect people and organisations from being misled or harmed by convincing but false digital material.

Process Improvement Initiatives

Process improvement initiatives are organised efforts within a business or organisation to make existing workflows, procedures, or systems more efficient and effective. These initiatives aim to reduce waste, save time, lower costs, or improve quality by analysing current processes and identifying areas for change. They often involve gathering feedback, testing new methods, and measuring results to ensure lasting improvements.

Digital Strategy Playbooks

A digital strategy playbook is a structured guide that outlines how an organisation can use digital tools and channels to achieve its business goals. It includes recommended actions, timelines, and best practices for areas like social media, websites, mobile apps, and digital marketing. Playbooks help teams stay consistent and organised as they implement digital initiatives.

Low-Code Platforms for Business Users

Low-code platforms for business users are software tools that allow people with little or no coding experience to build applications using visual interfaces and simple logic. These platforms use drag-and-drop features and pre-built templates to help users create apps quickly and efficiently. They reduce the need for traditional programming, making it easier for business teams to solve problems and automate tasks themselves.
