Abstract: Composite electrodes are described herein, comprising a stainless steel substrate and silicon-containing nanostructures extending from the substrate, as well as processes for preparing such electrodes without requiring a catalyst by pre-treatment of the steel. At least a portion of the silicon-containing nanostructures are characterized by: being substantially devoid of a non-silicon catalyst material and/or a noble metal; and/or including along its length a metal constituent originating from the steel substrate; and/or including a metal silicide extending from the substrate and along at least a portion of its length; and/or being fused with at least one other silicon-containing nanostructure at a location removed from a surface of the substrate to form a sponge-like three-dimensional structure; and/or being stainless steel nanostructures having a layer of silicon disposed thereon.

Abstract: A method for providing secure access to cloud computing resources comprising: monitoring communications in sessions between a cloud computing resource, CCaaS, of cloud computing resources and users using web browsers comprised in user equipment, UE, to access the CCaaS; processing the monitored communications to accumulate data for at least one component or any combination of more than one of a set, CCaaS-KPI, of key performance indicators, KPIs, that characterize operation of the CCaaS during the sessions, a set, UE-KPI, of key performance indicators characterizing operation of the user equipment, UE, during the sessions, a set, U-KPI, characterizing actions of users accessing the CCaaS during the sessions, and/or a set, SMETA, of session metadata components that provide indexing and descriptive data for the sessions; processing the accumulated data to determine patterns characterizing normal interaction of users with the CCaaS; and using the normal patterns to detect an anomaly in a user session in which th

Abstract: A method for providing secure access to digital resources, the method comprising: monitoring communications between a website and a user using a web browser comprised in a user equipment (UE) that is useable to access the digital resources; processing the monitored communications to determine: a set (WVF) of website vulnerability features comprising features which as a result of the user connecting to the website render a digital resource of the digital resources with which the user communicates vulnerable to cyber damage; and a set of user browsing behaviour features (BHF) comprising features that characterize the user browsing behaviour and internet use pattern which render the digital resource vulnerable to cyber damage; determining based on the website vulnerability factors and the user profile a security risk indicator (SRI) having a value that provides an estimate of a cyber damage risk to the digital resource resulting from the user connecting to the website and the digital resource; and based on the S

Abstract: A communications system for providing secure access to a digital resource of a group of digital resources accessible via the internet, the system comprising: a data processing hub accessible via an IP (internet protocol) address; and a plurality of user equipment (UEs) useable to communicate via the internet, each configured to have a cyber secure isolated environment (CISE) isolated from ambient software in the UE, and comprising a secure web browser (SWB); wherein the hub and CISE are configured so that digital resources in motion and at rest in CISE are visible to the hub.
