Amid the worldwide pursuit of digital transformation, the software has seen a meteoric rise, and application security has become paramount. As more companies become software-centric, they publish more applications, increasing the risk vulnerable code will be released. To help reduce this risk, static application security testing (SAST) can help dev teams find and fix weaknesses in near-real-time. This means the software is made secure earlier in the software development lifecycle (SDLC), where it’s more cost-effective to fix and reduces overall risk.
Applications are the top attack vector for cybercriminals and the main source of breaches. Research has shown 83 percent of scanned applications contain at least one security flaw, and 20 percent contain at least one high severity security flaw. But it only takes one vulnerability for an attack to succeed.
Organizations are pushing more code, more often than ever before - sometimes multiple times a day, making it increasingly challenging to find and fix flaws before they’re released. Case in point, recent research from d Enterprise Strategy Group revealed nearly half of the organizations regularly release vulnerable code, in part because they find flaws too late in the SDLC.
Early SAST tools were used primarily by security professionals to discover weaknesses in source code. Unlike those early versions of static analysis tools that only assessed completed code at the end of the development cycle, today’s static analysis solutions check and secure code throughout the development cycle making them a valuable tool for app developers.
In keeping with the shift-left movement, developers are using SAST tools integrated with continuous integration/continuous delivery (CI/CD) and development environments to help build security into the development process and fix flaws in their code in their IDE.
There are several important benefits for organizations implementing SAST.
This last point is particularly important as security education is nearly absent in most computer programming degrees, leaving such training to employers. However, the ESG research found 50 percent of organizations only provide developers with security training once a year or less, and security training programs are insufficient to meet the demands being put on developers today. SAST gives developers real-time security feedback as they are coding, which helps them improve their knowledge of code vulnerabilities.
SAST is an important and effective tool for prerelease application security scanning, but it’s just one part of a comprehensive strategy. As such, organizations must consider how SAST integrates with other security and development tools in the environment and invest accordingly.
In an era of escalating threats and risks, it's essential to address application security as comprehensively as possible. Addressing code issues earlier in the SDLC is not only more cost-effective than remediating flaws later, but it also reduces risk overall. When implemented as part of a comprehensive, integrated application scanning program, SAST enables and empowers developers to take an active role in securing their code while increasing their security knowledge. And there’s no doubt educated, security-focused developers can improve the overall security posture of the application development environment.
