ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question
During a code review, a team decides to minify and obfuscate client-side JavaScript before releasing a commercial SaaS application. From a secure build-process perspective, what is the main security objective achieved by code obfuscation in this context?
It significantly increases the effort required for attackers to understand and reverse-engineer the application's proprietary logic.
It automatically eliminates client-side vulnerabilities like cross-site scripting by stripping out malicious code.
It ensures runtime detection of unauthorized code modifications through embedded digital signatures.
It provides end-to-end cryptographic protection for data exchanged between the browser and the server.
Obfuscation systematically transforms source or byte code into a functionally equivalent form that is far more difficult for humans to interpret. This raises the effort required for attackers to reverse-engineer proprietary algorithms or discover internal logic paths, thereby protecting intellectual property and hindering the creation of tailored exploits. Obfuscation does not remove existing vulnerabilities, encrypt data in transit, or verify integrity; those goals require separate controls such as secure coding practices, TLS, and digital code signing.
