-The paper is related to system and method for protection of an automated control system (ACS) against un-authorized devices connected to the ACS via wired or wireless channels that substantially obviates the disadvantages of the related art. The protection system monitors the signals spreading in the network analyzing the performance of the network for malicious code or hidden connections of attacker. The system is developed specifically for this purpose and it can protect the industrial control systems more effectively than standard anti-virus programs. Specific anti-virus software installed on a central server of the automated control system protects it fro m software-based attacks both fro m internal and external offenders. The system co mprises a plurality of bus protection devices of different types, including any of a twisted-pair protection device, a power lines protection device, On-Board Diagnostics signal protocol protection device, and a wireless protection device.

Nowadays mobile phone manufacturers offer their customers not only devices for calling and sending SMSmessages, but also multi-functional smartphones with much broader capability. Mobile phones are used to access the Internet, for e-mailing, social networking, finding phone owner`s location and routing, etc. Due to its multiple functionalities, a smartphone can store a lot of data that may be breached by theft or data leakage. This article focuses on development of security software for mobile devices able to detect malicious software and infected files on the device as well as to protect the user from applications recording personal conversations, secretly transmitting data and activating programs. Antivirus software monitors secret camera activation warning the user. The paper also provides the comparison of the proposed security software with popular antiviruses: Kaspersky Mobile Security, Dr.Web, ESET, Norton Antivirus, etc.
