Web applications continue to be the attack surface of choice for hackers attempting to access sensitive data. Per the “2020 Data Breach Investigations Report” from Verizon, successful attacks on web applications accounted for nearly half of all data breaches (43%), representing the single greatest cause of such breaches, and more than double the rate of the previous year.¹

Organizations clearly need to secure their web applications before they are deployed in production. But while development and application security (AppSec) teams often use static application security testing (SAST) and software composition analysis (SCA) solutions to identify security weaknesses and vulnerabilities in proprietary and open source code, they do so statically, at the code or component level. Many vulnerabilities can only be detected by dynamically testing an application during runtime test and release phases.

That’s why many organizations use dynamic application security testing (DAST) or penetration testing. DAST and penetration testing tools are run during QA or a late stage of production to detect vulnerabilities that can’t be found using SAST or SCA tools.

Additionally, while DAST and penetration testing can identify security vulnerabilities, they can’t pinpoint the lines of code containing the vulnerabilities. As a result, critical security issues identified by DAST can be problematic to fix and take a long time to resolve, putting remediation out of reach for the average developer.

Interactive application security testing

These challenges have led development and security teams to seek out alternative dynamic AppSec testing solutions such as interactive application security testing (IAST). IAST tools perform dynamic security tests concurrently during various test stages, while teams perform usual development and QA tests.

IAST tools can integrate seamlessly with continuous integration (CI) and test automation tools, as well as with agile and ad hoc test methodologies, and quickly generate analysis results that identify the specific lines of code where vulnerabilities reside. As a result, developers can fix issues quickly and push their commits as part of CI/CD or automation workflows.

More advanced IAST tools also incorporate SCA to uncover vulnerable third-party and open source components in an application.

Key benefits of IAST solutions

Actionable findings for development teams

IAST has been shown to reduce the time needed to remediate security vulnerabilities by 65% compared to penetration testing.² The reason for this is clear: IAST empowers developers to find and fix vulnerabilities as a part of the development process. Application security experts can remove themselves from the critical path of software development and spend more time on strategic security initiatives.

Comprehensive vulnerability and security risk reporting earlier in the SDLC

IAST enables developers to fix security vulnerabilities as they test. This means finding and fixing runtime vulnerabilities in web apps before deploying them to production. “Shifting left”—doing security testing earlier in the integrated build and testing stages—shortens test cycles and enables substantial cost and resource savings while also reducing security risk.

Low false-positive rates

IAST solutions automatically verify the results, ensuring a high degree of accuracy. They don’t return a high number of false positives that require lengthy manual reviews, troubleshooting, and additional scans to resolve. IAST allows organizations to focus their security resources on more difficult corner-case vulnerabilities that require specialized expertise to identify and verify.

Seamless integration into automated development and testing environments

IAST solutions integrate seamlessly into CI/CD pipelines and run at the speed demanded by agile and DevOps. Both security and development teams benefit from integrating IAST into the SDLC—especially an IAST tool that provides SCA insights into vulnerable components, and contextual e-learning to help developers learn security on the jo

Earlier remediation at less cost and time

What to look for in IAST tools

There are many factors to consider when selecting IAST tools—and a handful of vendors to choose from. No matter which IAST solution your organization chooses, there are several minimum requirements to look for.

Updated security dashboards for standards compliance

Whether you’re beholden to PCI DSS, OWASP Top 10, GDPR, SANS/CWE, or other sets of compliance standards, your organization needs insight into security risks, trends, and coverage—as well as security compliance for running web applications and services, including proprietary code and open source components.

Fast, accurate, and comprehensive results—out of the box

Low false-positive rates mean you spend less time finding and remediating vulnerabilities. Your IAST tool should offer out-of-thebox functionality so you don’t waste time configuring and tuning tools to meet your requirements.

Real-time identification and reporting of vulnerabilities

Your IAST solution should automatically verify detect vulnerabilities and instantly prioritize vulnerabilities by severity levels so developers and AppSec teams can focus their time and resources on critical vulnerabilities that matter most to them.

Sensitive-data tracking

Organizations that need to achieve compliance with key industry security standards such as PCI DSS or GDPR need an IAST tool that lets them define the type of sensitive data they wish to automatically track and secure in their apps.

Ease of deployment in existing SDLC, agile, and DevOps workflows

Web application and DevOps teams rely on agile development and automation. Choose application security tools that seamlessly integrate with standard CI, test, and QA tools.

Enterprise-grade SCA binary analysis integration

Open source and third-party components, libraries, and frameworks are increasingly prevalent in web applications. Your IAST tool must provide visibility into open source security vulnerabilities and license types, as well as assurance that you’re compliant with license requirements.

Detailed security guidance and remediation advice

An IAST solution should provide developers with detailed and contextual information about vulnerabilities, where they are located in their code, and how to remediate them.

Optimal support for modern technologies

More and more organizations are using APIs, microservices and serverless architecture to achieve speed of business innovation. An IAST tool should help teams detect and trace data flows and any tainted data used.
