Why DAST and SAST Matter in Application Security Testing
DAST (Dynamic Application Security Testing) and SAST (Static Application Security Testing) are crucial for protecting applications from vulnerabilities and cyberattacks. Traditional security testing can overlook key vulnerabilities, and companies without comprehensive testing may face data breaches, compliance issues, and costly fines. That’s where DAST and SAST come into play. These testing methods provide proactive defense by identifying potential security risks at different stages of the development process, allowing for early and effective mitigation.
With DeshCyber’s flexible deployment options, companies can integrate DAST and SAST into their workflows seamlessly, choosing on-premise, cloud, or fully managed solutions to meet their unique needs. This blog will explain the differences, highlight key benefits, and provide real-life code examples to demonstrate how DAST and SAST enhance security.
What is DAST (Dynamic Application Security Testing)?
DAST is a black-box testing method, simulating real-world attacks on applications while they’re running to detect vulnerabilities. Unlike SAST, which looks at the code, DAST focuses on the application’s behavior during runtime.
Code Example: Detecting a Common Runtime Vulnerability with DAST
Consider a web application vulnerable to Cross-Site Scripting (XSS). DAST can simulate an attack by injecting scripts into the application, as shown below:
// User input simulation for XSS testing
let input = "<script>alert('XSS Attack')</script>";
// Check for vulnerabilities by simulating the input
document.getElementById("output").innerHTML = input;
DAST Detection: This code would trigger an alert due to the unsanitized input, revealing an XSS vulnerability. DAST flags the vulnerability by executing scripts that could harm users, providing developers with insights on fixing it
What is SAST (Static Application Security Testing)?
SAST is a white-box testing method, allowing developers to scan their code, bytecode, or binaries without running the application. By catching vulnerabilities in the code itself, SAST helps prevent issues before deployment, reducing risks and remediation costs.
Code Example: Identifying SQL Injection with SAST
In this example, SAST helps detect a potential SQL injection vulnerability:
// Vulnerable Code
String query = "SELECT * FROM users WHERE username = '" + username + "' AND password = '" + password + "'";
SAST Detection: SAST tools detect the SQL injection risk in this concatenated query. By flagging this issue, developers are prompted to use secure code practices like prepared statements:
// Secured Code with Prepared Statements
String query = "SELECT * FROM users WHERE username = ? AND password = ?";
PreparedStatement statement = connection.prepareStatement(query);
statement.setString(1, username);
statement.setString(2, password);
