Final answer:
A covert security alert is discreet and known only to a select group, while an overt security alert is transparent and meant for the general public. Covert alerts are similar to covert content in media that disguises political intent, whereas overt alerts are like overt content where biases are openly stated.
Step-by-step explanation:
The difference between a covert security alert and an overt security alert involves the visibility and intended audience of the information. A covert security alert is known only to a select group of people and not intended for public knowledge. These alerts are communicated in a discreet manner to prevent widespread awareness or possible panic. In contrast, an overt security alert is transparent and intended for the general public, broadcasting information widely so that everyone is aware and can take necessary precautions. This is similar to the use of covert and overt content in media information, where covert content presents political information without making clear its persuasive intent, while overt content transparently provides one side of a debate or opinion, as seen with political commentators or ideologically driven publications.
