The implementation of an information system is a complex process.It even more when it comes to business systems.These systems have now evolved into what are commonly known as enterprise systems.Then the threat cyberattacks must also be considered.In this paper we make brief overview major systems.Based on literature review identified most common vulnerabilities associated with them and some recommendations for stopping different kind threats against them.

The world is entering its new era of the industrial systems. endless development technology has undoubtedly improved efficiency processes. Internet Things essential to us these days. real and virtual worlds are already beginning merge into production, ushering in Industry 4.0 or fourth Industrial Revolution. In this article, we will discuss ways companies should approach security challenges inherent market, as well some recommendations them.

Too often, the unified security programs, based on comprehensive analy ses of information from across IT infrastructure, are costly, complex, difficult to implement and inefficient. As a result, most organizations lack accurate threat detection informed risk - management capabilities. Therefore, response new threats can be “security intelligence” approach. It is art ificial intelligence use its methods protect cybercrimes. The aim this study present compare different artificial intel ligence...

With the advent of digital technologies as an integral part today’s everyday life, risk information security breaches is increasing. Email spam, commonly known junk email, continues to pose a significant challenge in realm, inundating inboxes with unsolicited and often irrelevant messages. This relentless influx spam not only disrupts user productivity but also raises concerns, it frequently serves vehicle for phishing attempts, malware distribution, other cyber threats. The prevalence...

Decision making in critical situations is a complex process. There are many processes to consider. This paper describes theoretical approach researching attentional and automatic unconscious terms of metacognition. An application the presented explain decision metacognition as solution for ineffective cognitive biases during crisis situation. Evidence from studies on neuropsychology, control, architectures. recently formulated semiotic methodology implemented that allows design conceptual...

The fourth industrial revolution often referred as Industry 4.0 poses a great cybersecurity risk for Supervisory control and data acquisition (SCADA) systems. Lot of enterprises are changing the energy dependency that they have to be on wind power. These SCADA systems vulnerable against different kinds cyberattacks due IT OT convergence challenges observed. Thus, allowing attackers successfully exploit manipulate farm During our research concept attack scenarios going introduced. leveraging...

Artificial Intelligence (AI) is a very promising field of development, in many directions. It widespread computer technology (biotechnology, nanotechnology, Internet Things, etc.) as well robotics, 3D printing, quantum computing, and more. Using it to predict defend from cyber attacks another its applications. In conduct project study the security cyber-physical connections context next-generation networks, an overview AI methods their application Industry 4.0 has been made. More attention...

The Faculty of Computer Systems and Technology at Technical University – Sofia undertook analyses experiments on the use Artificial Intelligence methods in field Information Security. In course study a Cyber Defence related to classification consisting three phases has been proposed: Operative Intelligence, Tactical Incident Handling. It found that there is no universal method effective for all mentioned above applications. each case, set criteria should be developed select (and then...

In the current age, cyber security is an essential element of any information system. A key aspect in critical infrastructure, where has become a top priority for and network experts. The interoperability ICT infrastructure with other components it important its life cycle. Because Supervisory Control Data Acquisition (SCADA) systems form part their protection particularly strategically industrial sites — power plants, refineries, oil pipelines, treatment manufacturing facilities,...

This article presents a brief overview of the effect new technologies, how they are changing manufacturing process, and machines starting to get lot smarter thanks artificial intelligence. The focus is over examination Industry 4.0 it revolutionized whole segment what promise better, more efficient future brings. analysis focuses primarily on intelligence integrated, benefits brings, big an improvement basic programming. Part research based 771 publications tracked past three five years....

An issue of the Internet Things security which does not belong to traditional problem cybersecurity, as it is a local or distributed monitoring and/or physical systems state connected via Internet, considered. architecture Supervisory Control and Data Acquisition system (SCADA) was considered in previous authors studies. Due SCADA implementation, vulnerabilities various options cyberattacks on them were analyzed. As an example, case study based trees considered, obtained results summarized...

The present paper describes some of the results obtained in Faculty Computer Systems and Technology at Technical University Sofia implementation project related to application intelligent methods for increasing security computer networks. Also is made a survey about existing hybrid methods, which are using several artificial cyber defense. introduces model intrusion detection systems where multi agent bases intelligence applicable by means simple real-time models constructed laboratory environment.

Simulation methodology is becoming increasingly popular among computer network researchers worldwide in time of COVID pandemic. For selecting an appropriate simulator for a particular application, it important to have knowledge the tools available, along with their advantages and disadvantages. The basic ways installation are explained. A proposal good practice online simulators conducting laboratory exercises on networks has been made.

Computer security is defined as the protection of computer systems against threats to confidentiality, integrity and availability. Penetration a set actions compromise integrity, availability resources. To monitor events that occur in or networks called intrusion detection system (IDS). This paper introduces model for IDS based on multi-agent artificial intelligence.

An overview and analysis of security development standards best practices, as well comparison programming languages from the position code are presented in this paper. As a result conducted analysis, set principles criteria for secure software defined order to prevent accidental vulnerabilities programs.
