Which of the following members of a client organization are most likely authorized to provide a signed authorization letter prior to the start date of a penetration test?

The IT department typically manages systems but often lacks the ultimate authority for formal approval of a penetration test due to its potential impact and legal implications.

A penetration test involves simulating real-world attacks, potentially impacting business operations and data, and carries significant legal implications. Therefore, executive management (e.g., CEO, CIO, CISO) has the organizational authority to approve such an intrusive activity, while legal personnel ensure that the scope and terms comply with laws and internal policies, making their combined authorization crucial and legally binding.

Organizational security personnel define security requirements and may manage the penetration test, but they generally require executive-level authorization to proceed with a formal, potentially disruptive test.

The human resources team is responsible for personnel matters and has no direct authority or responsibility over authorizing technical security assessments like penetration tests.
