“…Firewalls protect assets by isolating private network networks from public networks by filtering traffic and blocking access to untrusted sources or IP addresses [89]. But the disadvantages of firewalls are also obvious, once an attacker breaches the network's defensive perimeter, the firewall cannot stop him from acting illegally on the internal network.…”

<p>Zero Trust Architecture (ZTA) is a paradigm shift in how we protect data, stay connected, and access resources. ZTA is non-perimeter based defense, which has been emerging as a promising revolution in the cybersecurity field. It can be used to continuously maintain security by safeguarding against attacks both from inside and outside of the network system. However, automation and orchestration ZTA, an essential direction towards its seamless deployments over real-word networks, have been poorly understood in literature. In this paper, we first identify the bottlenecks, discuss the background of ZTA and compare it with traditional perimeter-based security architectures. More importantly, we present a comprehensive direction towards the automation and orchestration of ZTA by employing AI techniques. In other words, the key potential and roles of celebrates AI techniques for the automation and orchestration of ZTA are demonstrated for further exploration. Overall, in this review paper, we develop a foundational view on the challenges and potential enablers for the automation and orchestration of ZTA.</p>

“…It acts like a subnetwork defender, but only in a workstation, meaning that this type of firewall can manage single or multiple hosts, but only within the same network. Being often used as proprietary-based software integrated into cloud platforms, personal firewalls generally have limited network customization facilities [54].…”

Smart healthcare environments are growing at a rapid pace due to the services and benefits offered to healthcare practitioners and to patients. At the same time, smart healthcare environments are becoming increasingly complex environments where a plethora of devices are linked with each other, to deliver services to patients, and they require special security measures to protect the privacy and integrity of user data. Moreover, these environments are exposed to various kinds of security risks, threats, and attacks. Firewalls are considered as the first line of defense for securing smart healthcare networks and addressing the challenges mentioned above. Firewalls are applied at different levels in networks, and range from conventional server-based to cloud-based firewalls. However, the selection and implementation of a proper firewall to get the maximum benefit is a challenging task. Therefore, understanding firewall types, the services offered, and analyzing underlying vulnerabilities are important design considerations that need addressing before implementing a firewall in a smart healthcare environment. The paper provides a comprehensive review and best practices of firewall types, with offered benefits and drawbacks, which may help to define a comprehensive set of policies for smart healthcare devices and environments.

As a critical infrastructure, the electric power grid is vulnerable with respect to malicious physical and cyber attacks. Indeed, the importance of physical and cyber security for smart grids has been highlighted by recent intrusion incidents worldwide. Various types of sensors, instrumentation, information and communications technology (ICT), computational methodologies, and security controls have been developed to enhance the physical and cyber security of the smart grid. In this paper, critical vulnerabilities of a smart grid that can be exploited for physical and cyber intrusions are discussed. A comprehensive survey is conducted on the state‐of‐the‐art research to enhance the physical and cyber security in a smart grid environment. Furthermore, the interdependency of physical and cyber security is illustrated with an intrusion scenario. The emphasis is on the physical and cyber security of power substations. Computer simulation results for a case study are presented. WIREs Energy Environ 2016, 5:519–542. doi: 10.1002/wene.202 This article is categorized under: Energy Infrastructure > Systems and Infrastructure
