This article discusses the vulnerabilities and complexity of designing secure IoT-solutions, and then presents proven approaches to protecting devices and gateways. Specifically, security mechanisms such as device authentication (including certificate-based authentication), device authentication, and application a verification of identification are described. The authors consider a protocol of message queue telemetry transport for speech and sensor networks on the Internet, its features, application variants, and characteristic procedures. The principle of "publishersubscriber" is considered. An analysis of information elements and messages is carried out. The urgency of the theme is due to the rapid development of "publisher-subscriber" architecture, for which the protocol is most characteristic.

Nowadays, Memory Forensics is more acceptable in Cyber Forensics Investigation because malware authors and attackers choose RAM or physical memory for storing critical information instead of hard disk. The volatile physical memory contains forensically relevant artifacts such as user credentials, chats, messages, running processes and its details like used dlls, files, command and network connections etc. Memory Forensics involves acquiring the memory dump from the Suspect's machine and analyzing the acquired dump to find out crucial evidence with the help of windows pre-defined kernel data structures. While retrieving different artifacts from these data structures, finding the network connections from Windows 7 system's memory dump is a very challenging task. This is because the data structures that store network connections in earlier versions of Windows are not present in Windows 7. In this paper, a methodology is described for efficiently retrieving details of network related activities from Windows 7 x64 memory dump. This includes remote and local IP addresses and associated port information corresponding to each of the running processes. This can provide crucial information in cyber crime investigation.
