Final answer:
Authorized access to DoD information and resources is granted based on a person's security clearance, which is a status granted after a thorough background investigation.
Step-by-step explanation:
Authorized access to DoD information and resources may be granted based on a person's security clearance. A security clearance is a status granted to individuals who have undergone a thorough background investigation and have been deemed eligible to access classified information.
There are different levels of security clearances, such as Confidential, Secret, and Top Secret, that determine the level of classified information an individual can access.
For example, to access highly sensitive information related to national security, a person would typically need a Top Secret security clearance.
