The identification of the cybersecurity (CS) state of Internet of things (IoT) devices determines the necessity to search for and improve approaches to detecting various threat types. The unification used in the mass development of IoT devices facilitates software and hardware modification to block certain built-in protective functions from the side of a potential intruder. A need arises to develop universal methods for identifying the cybersecurity state of devices using comprehensive approaches to analyzing data from internal and external information channels. The article presents an approach to identifying the cybersecurity of IoT devices based on processing time series recorded from sensors during various processes, and internal and external (thirdparty) sources. The approach is based on classification methods. The presented solution uses template sequences containing synchronized time series showing numerical values obtained from various probes and sensors during process execution. The proposed approach makes it possible to identify IoT device cybersecurity states without increasing the volume of information stored and processed in internal resources.

The causes of arterial embolism are acute myocardial infarction, heart aneurysms, valvular defects accompanied by cardiac arrhyth-mias. The rarer causes include myxoma of the left atrium, artificial valves, septic endocarditis, pneumonia, lung tumors, and previous acute viral respiratory infections. The new coronavirus infection is not an exception. SARS-CoV-2 contributes to parietal clotting, thromboembolic complications including acute arterial insufficiency. Adequate anticoagulation, antiplatelet and cardiac therapy cannot always protect the patient from such thromboembolic events. In this situation, only correct approach is imme-diate surgical recovery of arterial patency. We report successful surgical treatment of a patient with COVID-associated embolism in two arterial systems (brachiocephalic and lower limb arteries), that is a rather rare observation. Surgical treatment ensured com-plete regression of neurological and ischemic symptoms. © 2021, Media Sphera Publishing Group. All rights reserved.
