Implementing Enterprise Cybersecurity with Open-Source Software and Standard Architecture
Many small and medium scale businesses cannot afford to procure expensive cybersecurity tools. In many cases, even after procurement, lack of a workforce with knowledge of the standard architecture of enterprise security, tools are often used ineffectively. The Editors have developed multiple projects which can help in developing cybersecurity solution architectures and the use of the right tools from the opensource software domain. This book has 8 chapters describing these projects in detail with recipes on how to use opensource tooling to obtain standard cyber defense and the ability to do self-penetration testing and vulnerability assessment. This book also demonstrates work related to malware analysis using machine learning and implementation of honeypots, network Intrusion Detection Systems in a security operation center environment. It is essential reading for cybersecurity professionals and advanced students.

Cyber Breach Response That Actually Works
You will be breached-the only question is whether you'll be ready A cyber breach could cost your organization millions of dollars-in 2019, the average cost of a cyber breach for companies was $3.9M, a figure that is increasing 20-30% annually. But effective planning can lessen the impact and duration of an inevitable cyberattack. Cyber Breach Response That Actually Works provides a business-focused methodology that will allow you to address the aftermath of a cyber breach and reduce its impact to your enterprise. This book goes beyond step-by-step instructions for technical staff, focusing on big-picture planning and strategy that makes the most business impact. Inside, you'll learn what drives cyber incident response and how to build an effective incident response capability. Expert author Andrew Gorecki delivers a vendor-agnostic approach based on his experience with Fortune 500 organizations. Understand the evolving threat landscape and learn how to address tactical and strategic challenges to build a comprehensive and cohesive cyber breach response program Discover how incident response fits within your overall information security program, including a look at risk management Build a capable incident response team and create an actionable incident response plan to prepare for cyberattacks and minimize their impact to your organization Effectively investigate small and large-scale incidents and recover faster by leveraging proven industry practices Navigate legal issues impacting incident response, including laws and regulations, criminal cases and civil litigation, and types of evidence and their admissibility in court In addition to its valuable breadth of discussion on incident response from a business strategy perspective, Cyber Breach Response That Actually Works offers information on key technology considerations to aid you in building an effective capability and accelerating investigations to ensure your organization can continue business operations during significant cyber events.

Network intrusion detection using a hybrid graph-based convolutional network and transformer architecture
Cloud computing continues to expand rapidly due to its ability to provide internet-hosted services, including servers, databases, and storage. However, this growth increases exposure to sophisticated intrusion attacks that can evade traditional security mechanisms such as firewalls. As a result, network intrusion detection systems (NIDS) enhanced with machine learning and deep learning have become increasingly important. Despite notable advancements, many AI-based intrusion detection models remain limited by their dependence on extensive, high-quality attack datasets and their insufficient capacity to capture complex, dynamic patterns in distributed cloud environments. This study presents a hybrid intrusion detection model that combines a graph convolutional layer and a transformer encoder layer to form deep neural network architecture. Using the CIC-IDS 2018 dataset, tabular network traffic data was transformed into computational graphs, enabling the model called “GConvTrans” to leverage both local structural information and global context through graph convolutional layers and multi-head self-attention mechanisms, respectively. Experimental evaluation shows that the proposed GConvTrans obtained 84.7%, 96.75% and 96.94% accuracy on the training, validation and testing set respectively. These findings demonstrate that combining graph learning techniques with standard deep learning methods can be robust for detecting complex network intrusion. Further research would explore other datasets, continue refining the proposed architecture and its hyperparameters. Another future research direction for this work is to analyze the architecture on other graph learning tasks such as link prediction.

Towards developing a secure medical image sharing system based on zero trust principles and blockchain technology
Background
Data security has been a critical topic of research and discussion since the onset of data sharing in e-health systems. Although digitalization of data has increased efficiency and speed, it has also made data vulnerable to cyber attacks. Medical records in particular seem to be the regular victims of hackers. Several data breach incidents throughout history have warranted the invention of security measures against these threats. Although various security procedures like firewalls, virtual private networks, encryption, etc are present, a mix of these approaches are required for maximum security in medical image and data sharing.
Methods
Relatively new, blockchain has become an effective tool for safeguarding sensitive information. However, to ensure overall protection of medical data (images), security measures have to be taken at each step, from the beginning, during and even after transmission of medical images which is ensured by zero trust security model. In this research, a number of studies that deal with these two concepts were studied and a decentralized and trustless framework was proposed by combining these two concepts for secured medical data and image transfer and storage.
Results
Research output suggested blockchain technology ensures data integrity by maintaining an audit trail of every transaction while zero trust principles make sure the medical data is encrypted and only authenticated users and devices interact with the network. Thus the proposed model solves a lot of vulnerabilities related to data security.
Conclusions
A system to combat medical/health data vulnerabilities has been proposed. The system makes use of the immutability of blockchain, the additional security of zero trust principles, and the scalability of off chain data storage using Inter Planetary File Systems (IPFS). The adoption of this system suggests to enhance the security of medical or health data transmission.
