The phase of vulnerability management that involves looking for existing security vulnerabilities on software applications is known as 'Identification'. This step precedes analysis, reporting, and remediation, focusing on discovering known and unknown vulnerabilities within the system or software to assess the security posture effectively.

Ephemeral storage is temporary storage that is tied to the lifecycle of a container or pod. When the container or pod is stopped, restarted, terminated, or rescheduled, all data stored in the ephemeral storage is permanently deleted. This type of storage is commonly used for temporary data like logs, cache files, or intermediate computation results that do not require long-term preservation.

Functional testing is a type of software testing that validates the software system against the functional requirements/specifications. The purpose of Functional tests is to test each function of the software application, by providing appropriate input, verifying the output against the Functional requirements.

A LUN is used by a transport protocol associated with an SCSI, iSCSI, Fibre Channel (FC) or similar interface. LUNs are central to the management of block storage arrays shared over a SAN.
