DAA
Step-by-step explanation:
DAA ( Designated approving authority ) is the authority charged with the supervision and authorization of the use of personal PED'S or contract owned PED'S to transmit classified data of the DOD ( department of Defense ) or even store DOD data.
The function of the DAA is to ensure that classified data doesn't fall into the wrong hands that are not cleared by the DOD to receive or have access to certain information and also to prevent hackers to tap into classified information/data for the purpose of undermining National security.
