Final answer:
Cornerstones defines indirect information warfare as manipulation of public opinion and communication systems, while the 303 definition pertains to the cognition of meaning-making from information.
Step-by-step explanation:
Cornerstones defines indirect information warfare as a form of military conflict that involves using information and media to manipulate public opinion, sow doubt, and disrupt communications. It is a strategy that aims to achieve strategic goals by exploiting vulnerabilities in information and communication systems. On the other hand, the 303 definition of information/meaning refers to the process of constructing and interpreting meaning from information. It focuses on how individuals attribute significance and make sense of the information they encounter. While indirect information warfare aims to manipulate and disrupt information, the 303 definition focuses on the cognitive aspect of processing information and deriving meaning from it.
