📌 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.

💡Other Useful Knowledge Cards

Byzantine Fault Tolerance

Byzantine Fault Tolerance is a property of computer systems that allows them to keep working correctly even if some parts fail or act unpredictably, including being malicious or sending incorrect information. It is particularly important in distributed systems, where multiple computers or nodes must agree on a decision even if some are unreliable. The term comes from the Byzantine Generals Problem, a scenario illustrating the difficulties of reaching agreement with unreliable participants.

Key Performance Indicators

Key Performance Indicators, or KPIs, are specific and measurable values that help organisations track how well they are achieving their goals. These indicators focus on the most important aspects of performance, such as sales numbers, customer satisfaction, or project completion rates. By monitoring KPIs, teams and managers can quickly see what is working well and where improvements are needed.

Cloud Monitoring

Cloud monitoring is the process of observing, tracking, and managing the performance, health, and availability of resources and services hosted in the cloud. It helps organisations ensure that their cloud-based applications, servers, databases, and networks are running smoothly and efficiently. Cloud monitoring tools provide alerts and reports, allowing teams to quickly detect and address any issues before they impact users.

Actor-Critic Methods

Actor-Critic Methods are a group of algorithms used in reinforcement learning where two components work together to help an agent learn. The actor decides which actions to take, while the critic evaluates how good those actions are based on the current situation. This collaboration allows the agent to improve its decision-making over time by using feedback from the environment.

Shadow AI Detection Protocols

Shadow AI Detection Protocols are methods and processes used to identify artificial intelligence tools or systems being used within an organisation without formal approval or oversight. These protocols help companies discover unauthorised AI applications that might pose security, privacy, or compliance risks. By detecting shadow AI, organisations can ensure that all AI usage follows internal policies and regulatory requirements.
