Medical IoT systems have recently become one of the most sophisticated medical technologies in well-developed countries. The remote monitoring of medical services may benefit greatly from this technology. According to a new study, security measures and training are critical in protecting IoMT systems from cyber-attacks. In this paper, the primary security and privacy challenges with IoMT are examined using current security solutions. Non-cryptographic and cryptographic approaches are used for a variety of attacks. It's therefore possible to compare the computational complexity of the various solutions and the resources they demand. Besides, the discussion of attack versions with causes for possible solutions, the dangerous scenarios of various attacks are also provided here. IoMT security methods, particularly in the rapidly expanding field of digital healthcare, show a trade-off between security level and system performance. There is a final section that talks about the acceptable security solutions, such as various attacks through common solution methods and protocols.
