Why are complex applications particularly vulnerable in Kubernetes?

1. They require extensive resources

2. They have multiple processes with public access

3. They are often built using outdated technologies

4. They can only be deployed in private clusters

The correct answer is: They have multiple processes with public access

Complex applications are particularly vulnerable in Kubernetes primarily because they consist of multiple processes that often have public access. Each microservice or component of a complex application interacts with others, which increases the potential entry points for an attacker. When these services are exposed to the public network, it opens up opportunities for malicious activities such as unauthorized access, data breaches, and exploitation of vulnerabilities in one service to compromise others. This multiplicity can complicate security configurations, as each component needs to be secured individually while still enabling necessary communication between them. Security best practices, such as using least-privilege access, network policies, and proper API management, become crucial to mitigate these risks effectively. When these practices are not correctly implemented or are overlooked due to the complexity, it can lead to significant vulnerabilities, making these applications targets for exploitation. The other options, while they may relate to challenges in Kubernetes, do not directly address the inherent vulnerabilities posed by the architecture of complex applications and their exposure in a cloud-native environment.
