Cybersecurity and Secure Information Systems: Challenges and Solutions in Digital Environment

Dear Colleagues,

In today's interconnected world, cybersecurity has become a paramount concern for businesses, governments, and individuals alike. As technology continues to advance at an unprecedented pace, the sophistication and frequency of cyber threats do too. This Special Issue of Systems invites contributions centered around the field of critical cybersecurity and secure information systems, addressing the persistent and evolving challenges in the digital environment. The research findings and solutions we encourage you to present should not only analyze the current state of cybersecurity but also propose innovative approaches that can effectively mitigate the risks and vulnerabilities faced by organizations and individuals. Your contributions should be focused, yet they should also effectively highlight the complex patterns and interdependencies within the cybersecurity landscape, like in impressionist art. The solutions and strategies proposed should be practical; thus, they should not just be theoretical concepts but should be implementable through the available technological and policy levers in the system.

In this Special Issue, original research articles, review papers, case studies, and conceptual papers are welcome. Research areas may include (but are not limited to) the following:

• Cryptography, encryption, and key management techniques;
• Network security, intrusion detection, and threat intelligence;
• Cloud security, privacy, and trust management;
• Blockchain and distributed ledger technologies for secure systems;
• Secure software development, testing, and vulnerability assessment;
• Human factors, social engineering, and cybersecurity awareness;
• Cybercrime, digital forensics, and incident response;
• Privacy, data protection, and compliance (e.g., GDPR and CCPA);
• Cybersecurity policies, governance, and risk management frameworks;
• Emerging threats, vulnerabilities, and countermeasures;
• AI, machine learning, and big data analytics for cybersecurity;
• IoT, embedded systems, and hardware security;
• Quantum computing and post-quantum cryptography;
• Cybersecurity education, training, and workforce development;
• Applications of large language models (LLMs) in cybersecurity;
• Natural language processing (NLP) techniques for cyber threat intelligence;
• Secure and privacy-preserving LLM architectures and training methods;
• Ethical considerations and the responsible deployment of LLMs in cybersecurity;
• Diffusion models for adversarial machine learning in cybersecurity;
• Digital forensics;
• Generative adversarial networks (GANs) for cybersecurity applications;
• Adversarial attacks and defenses in machine-learning-based cybersecurity systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Systems is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
