Understanding the Shared Responsibility Model in Serverless

In serverless computing, who is primarily responsible for securing the underlying infrastructure?

A The cloud service provider

B The end user

C The application developer

D Third-party security vendors

💡 Hint

Think about what the cloud provider manages versus what the developer controls.

In serverless, the cloud provider manages and secures the infrastructure, while developers focus on securing their code and data.

Common Security Risks in Serverless Architectures

Which of the following is a common security risk specific to serverless applications?

A Long-lived server sessions

B Physical server theft

C Function event data injection

D Manual patching of operating systems

💡 Hint

Consider how data passed to functions might be exploited.

Function event data injection occurs when attackers manipulate input events to execute malicious code in serverless functions.

Evaluating Access Control in Serverless Environments

Given a serverless application with multiple functions, what is the best practice to minimize security risks related to permissions?

A Grant all functions full access to all resources to avoid permission errors

B Use a single shared role for all functions to simplify management

C Disable all permissions and enable them only when an error occurs

D Use the principle of least privilege, granting each function only the permissions it needs

💡 Hint

Think about limiting access to reduce potential damage from compromised functions.

Applying the principle of least privilege limits each function's permissions to only what is necessary, reducing attack surface.

Impact of Cold Starts on Serverless Security Monitoring

How can cold starts in serverless functions affect security monitoring and incident response?

A Cold starts improve monitoring by providing more logs automatically

B Cold starts can delay function execution, causing gaps in real-time monitoring

C Cold starts disable security features temporarily

D Cold starts have no impact on security monitoring

💡 Hint

Consider how delays might affect the timing of alerts and logs.

Cold starts introduce latency that can delay function execution and logging, potentially causing gaps in real-time security monitoring.

Comparing Serverless Security to Traditional Server Security

Which statement best describes a key difference between serverless security and traditional server security?

A Serverless shifts infrastructure security responsibility to the cloud provider, reducing operational overhead

B Traditional servers eliminate the need for application-level security controls

C Serverless requires managing operating system patches, unlike traditional servers

D Traditional servers do not require network security measures

💡 Hint

Think about who manages what in serverless versus traditional setups.

In serverless, the cloud provider handles infrastructure security, allowing developers to focus on application security, unlike traditional servers where the operator manages both.
