Secure Software Design and Development
Secure Software Design and Development - Software security design and development refers to designing, building, and testing software to identify and eliminate potential problems or vulnerabilities. It is crucial to secure software during its development to prevent any bugs or vulnerabilities from being released to the public, thus minimizing risks. Ensuring that software is secured during the early stages of development can identify and address kinks within the software before moving on to continuous stages.
Application security testing is a crucial process used to identify and mitigate potential security vulnerabilities in software applications. Various tools and methodologies are employed to inspect the application's code, design, and functionality to find any potential security risks. These techniques can include static application security testing (SAST), which analyzes source code for vulnerabilities, dynamic application security testing (DAST), which tests the application in its running state, and interactive application security testing (IAST).
Application security testing is a crucial process that involves identifying vulnerabilities and weaknesses in software applications. The main goal of this testing is to ensure that the application is protected from various forms of threats such as data breaches, unauthorized access, and other cyber attacks. By conducting a thorough security assessment, businesses can detect and mitigate any potential security risks before they can cause any damage.
Application security testing can be carried out either manually or through automated tools. Manual testing involves a team of experts who examine the application's code, configuration files, and system architecture to identify any security issues. On the other hand, automated testing uses specialized software tools to scan the application for vulnerabilities and provide a detailed report.
A sample report from an application security test typically includes a list of identified vulnerabilities, their severity level, and recommendations to fix them. It is crucial for businesses to take action on these recommendations to ensure that their application is secure and free from potential threats. By doing so, they can protect their sensitive data, maintain customer trust, and avoid financial losses that can arise from cyber attacks.

Reflection
During the course, I thoroughly enjoyed the hands-on exercises where we used a vulnerable web application and multiple tools to uncover potential vulnerabilities. As cybersecurity professionals, it is our responsibility to continuously assess for vulnerabilities, with thousands of CVEs and OWASP vulnerabilities discovered every year.
We must address these issues to avoid potential damage to our organization that these vulnerabilities could cause. The course taught me that many organizations were hacked due to unpatched vulnerabilities or misconfigurations. Therefore, identifying critical vulnerabilities in web applications should be a top priority. To achieve this, various techniques such as static application scanning to review the existing code for insecure libraries, peer reviews to validate the code, dynamic crawling to identify the behavior of an application potentially allowing for an unauthorized access, interactive testing, or software composition analysis (SCA) review should all be deployed prior to application public deployment.
In the field of web application security, professionals are held to a high standard of ethical and professional conduct. This is because web applications often handle sensitive user data, and any vulnerabilities in their design or implementation can lead to serious privacy and security breaches. They must be diligent in their design and testing processes, and must also keep up-to-date with the latest security threats and best practices in order to ensure that the applications they are responsible for are as secure as possible.
