What are the best practices for securing cloud apps during penetration testing?

Testing should cover the application itself, its network communications, and its APIs, since cloud-hosted apps depend heavily on backend services and data flowing between them. Static analysis of the codebase combined with dynamic testing while the app is running helps catch both design flaws and runtime vulnerabilities. Following an established framework like the OWASP Mobile Top 10 provides a proven structure for uncovering the most serious issues across these layers.
