In a hospital, which guideline has likely NOT been violated following the theft of a laptop with unencrypted patient data?

The guideline that has likely not been violated following the theft of a laptop with unencrypted patient data is regarding network security measures. This is because the incident specifically pertains to the physical theft of a device rather than a breach or compromise of network security.

Network security involves protecting data as it travels across networks and generally includes measures such as firewalls, intrusion detection systems, and secure communication protocols. The theft of a physical device does not inherently indicate that these network protocols or firewalls were inadequate or that there was no protection in place for data traversing the network.

In contrast, the other guidelines emphasize the necessity of device-level protections, such as access controls and encryption, which were evidently not adhered to, given that the laptop contained unencrypted patient data. The lack of physical security measures could also be inferred, as the theft suggests that the laptop was not secured properly. Hence, while network security is a critical aspect of data protection, the specific theft incident does not point to a failure in this area.
