What is DAST and how does it work?
Dynamic application security testing (DAST) is a cybersecurity assessment method that analyzes running applications to identify security vulnerabilities. Unlike static application security testing (SAST), which examines source code before deployment, DAST scanning simulates real-world attacks by probing a web app’s inputs and responses. The term DAST is generally understood to refer to automated security testing using vulnerability assessment tools.
For small and mid-sized businesses, ease of use and speed are crucial when selecting a DAST solution. Many SMBs do not have dedicated security teams, so tools that provide automated scanning, straightforward setup, and actionable reports are essential. DAST tools help detect security flaws such as SQL injection (SQLi), cross-site scripting (XSS), authentication issues, and misconfigurations, providing an effective first layer of defense against hackers. They work as black-box testing solutions, meaning they do not require access to source code, which makes them compatible with various programming languages and web application security frameworks.
Why DAST-first is a better approach to AppSec
When it comes to testing their applications, most organizations rely on SAST, software composition analysis (SCA), and other static scanning tools that flood developers and security teams with false positives and non-actionable findings—and that’s a problem:
- SAST and SCA don’t prove exploitability but do frequently generate hundreds of alerts without showing what can actually be reached and attacked.
- Developers get overwhelmed and waste time fixing low-risk issues instead of real threats—and eventually start treating all security warnings as false alarms.
- Security teams lack clear prioritization when you can’t separate critical issues from less urgent tasks and from sheer noise.
A DAST-first approach flips this on its head:
- DAST scanning focuses on what attackers see by probing live applications to find exploitable vulnerabilities.
- Automated validation confirms potential vulnerabilities with features like proof-based scanning to cut through false positives.
- Faster remediation and higher efficiency with short time to value as teams focus on first fixing what matters most.

E20 Petrol in India: Green Revolution or Hidden Scam?
For the past few years, India has been pushing hard towards adopting alternative fuels and reducing its dependency on imported crude oil. One of the most talked-about initiatives is the rollout of E20 petrol, which is a blend of 80% petrol and 20% ethanol. On paper, this looks like a revolutionary step — it’s designed to reduce carbon emissions, cut down fuel imports, and boost ethanol demand that directly benefits Indian farmers. But there’s a rising question among common people: If E20 petrol contains only 80% petrol, why are we still paying the same price as regular petrol? Shouldn’t the price be lower since 20% of the mix is ethanol, which is significantly cheaper to produce compared to crude oil-based petrol? This is where many start suspecting that the promotion of E20 might not be as transparent as it seems. […]
JSON Web Token Attacks And Vulnerabilities
[ad_1] JSON Web Tokens (JWTs) are a widely used method for securely exchanging data in JSON format. Due to their ability to be digitally signed and verified, they are commonly used for authorization and authentication. However, their security depends entirely on proper implementation—when misconfigured, JWTs can introduce serious vulnerabilities. This guide explores common JWT attacks and security flaws, providing a technical deep dive into how these weaknesses can be exploited and how to mitigate them. The Structure of a JSON Web Token (JWT) A JSON Web Token (JWT) is composed of three parts: a header, payload, and signature, all encoded using Base64URLand separated by dots. The format follows this structure: HEADER.PAYLOAD.SIGNATURE Here is an example of a real JWT: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9. eyJuYW1lIjoiSm9obiBEb2UiLCJ1c2VyX25hbWUiOiJqb2huLmRvZSIsImlzX2FkbWluIjpmYWxzZX0. fSppjHFaqlNcpK1Q8VudRD84YIuhqFfA67XkLam0_aY Breaking Down the JWT Header The header contains metadata that defines the token’s properties, including: The algorithm (alg) […]
Mitigating Fragmented SQL Injection Attacks: Effective Solutions
[ad_1] This blog post breaks down Fragmented SQL Injection, a method hackers use to bypass authentication by manipulating two different input fields at the same time. Our security expert explains why single quotes matter in SQL injection attacks and how using Prepared Statements (also called Parameterized Queries) can effectively prevent these types of exploits. LEARN MORE: How to prevent SQL Injection If you ask someone how to check for an SQL injection vulnerability in a web application, their first suggestion might be to enter a single quote (‘) into an input field. If the application responds with an error, it could indicate that the input is interfering with the database query—a classic sign of SQL injection. In fact, some people even refer to SQL injection as “Single Quote Injection” because of how often this method is used to test for […]
Preventing CSRF Attacks with Anti-CSRF Tokens: Best Practices and Implementation
[ad_1] The most widely used method to prevent cross-site request forgery (CSRF) attacks is the implementation of anti-CSRF tokens. These are unique values generated by a web application and validated with each request to ensure authenticity. CSRF attacks exploit a user’s active session to execute unauthorized actions, such as redirecting them to a malicious website or accessing sensitive session data. To effectively mitigate these risks, it is essential to generate, manage, and validate CSRF tokens correctly, ensuring robust protection against unauthorized requests. What Is an Anti-CSRF Token? An anti-CSRF token (also known as a CSRF token) is a security mechanism designed to verify the legitimacy of a user’s request. It works by assigning a unique, unpredictable token to the user’s browser, which must be included in subsequent requests. This ensures that the request originates from the authenticated user and not […]
XSS Filter Evasion: How Attackers Bypass XSS Filters – And Why Filtering Alone Isn’t Enough
[ad_1] XSS filter evasion techniques allow attackers to bypass cross-site scripting (XSS) protections designed to block malicious scripts. This article explores some of the most common filter bypass strategies, explains why relying solely on filtering is ineffective, and outlines the best practices for preventing XSS attacks. Attackers have developed hundreds of methods to evade XSS filters, making it clear that filtering alone is not a foolproof defense. For an XSS attack to succeed, two conditions must be met: The application must have an XSS vulnerability that allows user-controlled input to be injected into web pages. The attacker must find a way to execute malicious JavaScript within the victim’s browser. XSS filtering aims to stop these attacks by detecting and removing suspicious code before it reaches the browser. However, because attackers continuously develop new techniques to disguise or encode their payloads, […]
