Question

A development team is migrating a large monolithic application to a microservices architecture running in separate containers, each exposing its own API. The security manager is documenting the security implications of this design change. Which of the following is the MOST significant security consideration introduced by this migration?

Accepted Answer

The increased number of exposed service endpoints expands the overall attack surface that must be secured

Answer

Microservices eliminate the need for network segmentation because each service is already isolated

Answer

Patching becomes impossible because each container runs an embedded real-time operating system

Answer

Microservices remove all availability concerns because a single service failure cannot affect others
