Embodiments are directed to detecting one or more attacks in a network. One or more network flows may be monitored using one or more network monitoring computers (NMCs). If one or more file write operations are detected based on information included in one or more packets of the one or more network flows, one or more detection rules may be executed to analyze one or more portions of the one or more packets to identify file information that is associated with the one or more file write operations. One or more metrics may be provided based on the one or more detection rules and one or more of the file information, the one or more file write operations, or the like. If one or more metrics exceed one or more threshold values, one or more reports of one or more attacks may be provided.

Detecting attacks using passive network monitoring

Embodiments are directed to monitoring communication over a network using a network monitoring computer (NMC). If one or more flows include healthcare traffic provided by one or more healthcare services, the NMC may perform further actions. Healthcare values from the one or more healthcare services may be provided from the network traffic. Values from one or more network traffic flows that are separate from the healthcare traffic may be provided. Other healthcare values from other flows may be provided that include healthcare traffic provided by the healthcare services. Accordingly, if a comparison of the healthcare values and the other healthcare values meet certain conditions, additional actions may be performed based on rules, or policies. The healthcare traffic may be compliant with one or more of Health Level Seven (HL7) standard, Digital Imaging and Communications in Medicine (DICOM) standard, or the like.
