  Researchers are now focusing on 6G as a new network technology that will
bring significant gains over the previous generations while many sectors are
still implementing the 5G network in their business processes and operations.
Meanwhile, key technological fields that will be influenced by 6G networks have
been identified. These include distributed artificial intelligence, intelligent
radio, real-time intelligent edge computing, and 3D intercoms. Additionally,
each area and potential application of 6G is supported by relevant emerging
technologies. Nevertheless, these 6G technology and applications have
significant security vulnerabilities that must be addressed before the complete
adoption of 6G networks. The healthcare is one of the sectors that are
benefiting from the great features introduced in the 5G networks that enhance
digital communications and data protection; that notwithstanding, there are
still security flaws in 5G technologies that can be transferred to the 6G
networks if not properly addressed. This paper highlights the key areas of 6G
networks that would provide grand support for the development of healthcare
systems. It also identifies certain vulnerabilities in the previous cellular
networks that are transferable to 6G networks, and suggests security strategies
including zero trust initiatives that could be implemented to address the
security concerns.
