Within the actual healthcare sector exists two further sorts of bricks, Health IT and Health Cybersecurity. Health IT refers to systems and technology used to collect, store, and manage health related records and data/information, such as patient data or electronic health records. Healthcare cybersecurity goes in hand with Health IT - it is the protection of these Health IT systems and data from threats, such as data breaches which puts patients' information at risk, or DDoS attacks which overwhelm Health systems networks and block access to things like electronic health records. 

Both Health IT and Healthcare cybersecurity depend on each other to successfully function. Health IT needs Healthcare Cybersecurity to protect their services so they can continue storing and managing health information securely, and Health Cybersecurity needs Health IT to even work, since it's all about protecting Health IT. If there is a breach in Healthcare Cybersecurity that only puts Health IT at risk. For example: if a Health IT network is hit with a DDoS attack, the servers get flooded with traffic making health records inaccessible. Without Healthcare Cybersecurity, these records can't be accessed when it's really needed. Health Cybersecurity can prevent this from happening through things like mitigation and redirection of this traffic through set filters or blocking it using firewalls that only allow specific IP addresses and drop suspicious packets. This dependency on each other also causes problems to arise, a poor cybersecurity scene greatly puts Health IT at risk.
