Integrated sensing and communication (ISAC) is regarded as a recent advanced technology, which is expected to realize the dual functions of sensing and communication simultaneously in one system. Nevertheless, it still faces the challenges of the information security and transmission robustness caused by the openness of wireless channel, especially under antagonistic environment. Hence, this article develops a generalized framework, named cognitive joint jamming, sensing and communication (cognitive J 2 SAC), to empower the current sensing/communication/jamming system with a "brain" for realizing precise sensing, reliable communication and effective jamming under antagonistic environment. Three kinds of gains can be captured by cognitive J 2 SAC, including integrated gain, cooperative gain and cognitive gain. Moreover, we highlight the enabling mechanism among jamming, sensing, and communication, as well as illustrating several typical use cases of cognitive J 2 SAC. Furthermore, several key enabled technologies are analyzed and a typical sensing enhance integrated communication and jamming case study is discussed to verify the effectiveness of the proposed method. Last but not the least, the future directions are listed before concluding this article.
