An Asynchronous AAA Blockchain-Based Protocol for Configuring Information Systems

Energies (2022)

Michał Bajor Marcin Niemiec

The increasing number of security breaches in centralized systems provides the necessity to introduce decentralization in more fields. The Blockchain is a widely utilized decentralization technology that is implemented in various industries. Therefore, this technology can be used to protect sensitive services, such as those associated with the configuration changing of information systems. This article proposes a new protocol operating as a decentralization layer over any configuration scheme. It uses smart contracts—programs existing on the Blockchain—to keep track of configuration proposals and authorize new configurations. The configuration change can be proposed at any time. However, only once it is authorized by appropriate parties can it be introduced to the system. The new protocol provides an additional security layer, ensuring that every action is accounted for and authenticated. Furthermore, it enforces that administrators authorize every change. The protocol was designed to be flexible and easily adaptable to scenarios that did not use distributed ledger technology before. It uses the HTTP protocol with the JSON standard for protocol messages to allow easier adoption and transparency. The features of the proposed protocol were analyzed from a security point of view as well as from the financial perspective related to costs of using Blockchain technology. Security analysis shows that the protocol is resilient to the most common security risks that haunt state-of-the-art IT systems. Additionally, the authors proved that this solution could be implemented in both private and public Blockchains. A reference implementation was shared in a public repository. The proposed protocol was also compared with the most similar state-of-the-art work in the academic research highlighting the key differences and improvements.

Heuristic-based Intrusion Detection Functionality in a Snort Environment

Information & Security An International Journal (2021)

Bartłomiej Gdowski Rafał Kościej Marcin Niemiec

This article provides an introduction to intrusion detection systems, focusing on extending the Snort environment's functionalities by adding a new heuristic detection algorithm.The algorithm allows to detect selected types of cyberattacks through analysis of received packets and based on a list of malicious Internet Protocol addresses.Furthermore, the algorithm underwent functional verification.The results confirmed that the algorithm successfully detects the packets originating from the provided list and rates them accordingly.

Quantum cryptography - The analysis of security requirements

Marcin Niemiec

This article describes the security requirements of communication systems from quantum cryptography point of view. The background of consideration is the model of secure communication system, presented in ITU-T recommendation X.805. The requirements are described in two sections: end-users requirements, which should be clarified at the beginning of security architecture designing and system requirements, which should be met before quantum cryptography implementation.

GDC 2: Compression of large collections of genomes

Scientific Reports (2015)

Sebastian Deorowicz Agnieszka Danek Marcin Niemiec

Abstract The fall of prices of the high-throughput genome sequencing changes the landscape of modern genomics. A number of large scale projects aimed at sequencing many human genomes are in progress. Genome sequencing also becomes an important aid in the personalized medicine. One of the significant side effects of this change is a necessity of storage and transfer of huge amounts of genomic data. In this paper we deal with the problem of compression of large collections of complete genomic sequences. We propose an algorithm that is able to compress the collection of 1092 human diploid genomes about 9,500 times. This result is about 4 times better than what is offered by the other existing compressors. Moreover, our algorithm is very fast as it processes the data with speed 200 MB/s on a modern workstation. In a consequence the proposed algorithm allows storing the complete genomic collections at low cost, e.g., the examined collection of 1092 human genomes needs only about 700 MB when compressed, what can be compared to about 6.7 TB of uncompressed FASTA files. The source code is available at http://sun.aei.polsl.pl/REFRESH/index.php?page=projects&project=gdc&subpage=about .

Universal privacy‐preserving platform for SecaaS services

International Journal of Network Management (2017)

Tytus Kurek Marcin Niemiec Artur Lasoń Andrzej R. Pach

Summary With the rapid growth of the Security‐as‐a‐Service market, concerns about privacy in exposing customer security policies to Cloud Service Providers have become critical. To resolve these issues, several solutions have been proposed over the past few years, each for a different kind of security service. However, as the number of security services outsourced into a cloud continues to grow, the need for a unified solution has become significant. This article introduces and presents a universal privacy‐preserving platform for SecaaS services that is based on a hybrid cloud architecture for maintaining the confidentiality of the customer's security policy. It is shown that this platform can be applied to all security services whose security policies can be represented in the form of a decision tree. This includes the vast majority of existing cloud‐based security services. With the small number of computationally‐expensive operations performed in a private cloud, the solution also does not require the implementation of a performant security engine on the customer's premises, allowing full advantage to be taken of private cloud offloading. It is also shown that the platform achieves better performance results than other existing solutions of this type. These findings were confirmed by experimental results.
