Organizations developing applications have in-place a process by which each application is designed, developed, tested, and deployed. This sequence of stages that define these processes is called the software development lifecycle, often referred to as the SDLC. An organization’s SDLC helps shape the way their apps are built and defines the exact processes each application should go through, as well as the milestones an application needs to hit before going to the next stage of the SDLC.
A Secure SDLC is a process which has security touch points in every stage, as well as security milestones. Secure SDLC’s go above and beyond the current SDLC structure in order to ensure that the applications being deployed are secure upon release, without creating a delay in the original SDLC.
The biggest advantages of organizations adopting a secure SDLC is to create a high-quality, secure product
Both SDLC and Secure SDLC typically revolve around five stages, where within each stage of the SDLC (Requirements, Design, Development, Testing, and Deployment) there are security processes to be done during that time: Risk assessment, threat modeling and design review, static analysis, security testing and code review, and finally security assessment and secure configuration.

Static code analysis (SCA) is one of the driving forces behind the secure SDLC philosophy after the requirements have been clearly defined and clarified to the developers.
One of the biggest advantages of using static code analysis throughout the SDLC is that testing can be fully automated, enabling developers to implement secure coding practices and sanitize the whole development process with minimal effort. Product release deadlines can then be easily met without cutting corners or releasing with risky security issues.
In a Secure SDLC, static code analysis tools can quickly find and help developers protect against SQL Injections, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF) and other malicious attacks. Without a Secure SDLC using static code analysis, there’s no assurance that an application is released without security vulnerabilities.
Why companies need to integrate security testing tools in a Secure SDLC for secure applications
Web threats are one of the largest potentially-devastating risks that companies with a web presence face today. Malware is the leading threat to companies, and the costs associated with defending from and recovering from malware attacks stretches into the billions of dollars each year. However, network security has become incredibly efficient in recent years, which has caused attackers to turn their attention to other vulnerable areas – especially the application layer. Application code with security flaws can be exploited to have devastating, unintended consequences on an organization and its’ customers. Data breaches cost companies millions of dollars annually, but software testing tools offer a helpful line of defense against such malicious attacks.
