CompTIA Exam CAS-004 Topic 10 Question 42 Discussion

Static application security testing (SAST) is a method of analyzing the source code of an application for vulnerabilities and weaknesses before it is deployed. SAST can help identify security issues earlier in the development process, reducing the time and cost of remediation. Dynamic application security testing (DAST) is a method of testing the functionality and behavior of an application at runtime for vulnerabilities and weaknesses. DAST can cover public-facing application components, but it cannot detect issues in the source code or in serverless applications. Runtime application self-protection (RASP) is a technology that monitors and protects an application from attacks in real time by embedding security features into the application code or runtime environment. RASP can help prevent exploitation of vulnerabilities, but it cannot identify or fix them. A web application firewall (WAF) is a device or software that filters and blocks malicious web traffic from reaching an application. A WAF can help protect an application from common attacks, but it cannot detect or fix vulnerabilities in the application code or in serverless applications.Reference: [CompTIA Advanced Security Practitioner (CASP+) Certification Exam Objectives], Domain 3: Enterprise Security Operations, Objective 3.4: Conduct security assessments using appropriate tools
