SDL Security Testing & Code Analysis

Question 1

What is the purpose of security testing in software development?

Accepted Answer

To detect security flaws and vulnerabilities

Answer

Security testing is a crucial phase in the Software Development Lifecycle (SDL) specifically designed to identify weaknesses and loopholes in software. Its primary goal is to uncover security flaws, vulnerabilities, and potential threats that could be exploited by malicious actors, ensuring the software is robust against attacks before deployment.

Question 2

Which testing method involves analyzing source code without execution?

Accepted Answer

Static Application Security Testing (SAST)

Answer

Static Application Security Testing (SAST) is a white-box testing method that analyzes an application's source code, bytecode, or binary code without actually executing the program. It identifies potential security vulnerabilities such as buffer overflows, SQL injection flaws, and cross-site scripting issues early in the development cycle. This allows developers to fix security defects before the software is compiled and run.

Question 3

What does Dynamic Application Security Testing (DAST) do?

Accepted Answer

Simulates attacks on running software

Answer

Dynamic Application Security Testing (DAST) is a black-box testing method that analyzes an application in its running state, typically from the outside. It simulates real-world attacks against the live application to identify vulnerabilities that might only appear during execution, such as authentication bypasses or server misconfigurations. DAST tools interact with the application through its web interface or APIs, much like an attacker would.

Question 4

Why is code review important in security testing?

Accepted Answer

It improves code quality and security

Answer

Code review is a critical practice in security testing where developers manually or automatically examine source code for errors, adherence to coding standards, and potential security vulnerabilities. This collaborative process helps identify design flaws, logic errors, and security weaknesses that automated tools might miss, ultimately leading to more secure and higher-quality software. It fosters knowledge sharing and reduces the likelihood of introducing new bugs.

Question 5

What is fuzz testing?

Accepted Answer

Feeding random data to find bugs

Answer

Fuzz testing, or fuzzing, is a software testing technique that involves intentionally injecting malformed, unexpected, or random data inputs into a software program. The goal is to discover software bugs, security vulnerabilities, or crashes that occur when the program attempts to process these unusual inputs. It's particularly effective at uncovering edge cases and robust error handling issues.
