As a result of digitalization, business mobility is a need-to-have, not a nice-to-have. People engage, communicate, and transact via a variety of devices, while software continues to take its place as the new dominant component of information technology, VMware explained. Competition is aggressive and a highly accelerated speed of business is expected. While employees want to be able to work from anywhere, using any device, customers are demanding personalized experiences and expect products, services, and answers instantaneously. In the absence of a central solution for enabling a digital workspace and delivering secure, real-time access to data and applications across devices and location through identity and policy, IT teams are dealing with organized chaos at best.

Greater Flexibility and Interoperability for Operators Virtualizing Their Software Defined Fiber Access Networks

Broadband Forum | July 14, 2022

Operators can now reduce the time and cost associated with onboarding new Optical Network Unit (ONU) vendors, roll-out services faster, and more easily migrate and evolve their networks by applying new innovations and flexibility thanks to the publication of two new documents from the Broadband Forum today. Broadband Forum’s TR-451 ‘vOMCI Specification’ and MR-451 ‘ONU Management using Virtualized OMCI’ have armed operators with more choice in how they create, activate, and maintain services associated with ONUs. Previously, the management cycle of the ONU was tied to a specific vendor’s Optical Line Terminal (OLT). The latest specification enables operators to de-couple the ONU and OLT from control and management purposes, with the Virtualized ONU Management (vOMCI) being introduced as a solution to centralize operations without relying on each OLT to act as a management entity. This means operators’ OLT vendors no longer needed to be intimately involved in the roll-out of the management services and features provided by the ONU. TR-451 also increases the number of potential ONU vendors, allowing operators to better negotiate the best prices for ONUs. The specification enables easier interoperability testing and on-boarding of ONUs within an operator’s ecosystem and cloud-based network. It supports various deployment models where virtualized functions can be deployed to the cloud or within existing management system solutions. “The latest specification can be used in the evolution of the management of ONUs, not as a replacement for the management processes and data models already in use by operators but to future-proof their infrastructure while maintaining their investment in existing ONU devices,” said Bruno Cornaglia, Co-Director of the SDN/NFV Work Area at Broadband Forum. “Ultimately, ONU management will be more adaptive to changes in operators’ processes and services, as well as less costly to maintain.” About the Broadband Forum Broadband Forum is the communications industry’s leading open standards development organization focused on accelerating broadband innovation, standards, and ecosystem development. Our members’ passion – delivering on the promise of broadband by enabling smarter and faster broadband networks and a thriving broadband ecosystem.

Deloitte Launches Zero Trust Access, a New Managed Security Service

Deloitte | July 16, 2022

To help organizations adopt zero trust more quickly and efficiently, Deloitte is launching a new managed service – Zero Trust Access— that offers a cloud-native approach to securing communications between users, on any device, and enterprise applications, wherever they may reside. The Zero Trust concept commits to removing implicit trust within an information technology (IT) ecosystem and replacing it with a risk-based approach to accessing organizational resources across identities, workloads, data, networks and devices. This trend is gaining momentum, given legacy approaches to security architecture are no longer suitable to secure the ubiquitous nature of the modern enterprise. Part of the newly expanded Zero Trust by Deloitte, Zero Trust Access facilitates zero trust adoption and the evolving needs of organizations in protecting their applications, infrastructure, and data. Following the integration of recently acquired talent and technology into existing Deloitte services, the Zero Trust Access managed service connects users to applications through a frictionless cloud-native solution that is inherently scalable, resilient, agile, and secure. Further, the managed service is available standalone, integrated with other Deloitte offerings, or as part of a broader solution leveraging technologies from Deloitte's alliances ecosystem. "As perimeter-based approaches are no longer suitable to secure the modern enterprise, many organizations are working to enhance protection for their IT ecosystems via zero trust, Zero Trust Access was built as a turnkey managed service helping ourselves and our clients accelerate adoption of this transformative security framework. Our goal was to create a cost-effective solution that can be delivered standalone or complementary to a broader ecosystem and ultimately help decrease the burden on IT and security teams who likely need to manage multiple heterogenous solutions to achieve similar outcomes." Andrew Rafla, Deloitte Risk & Financial Advisory's zero trust offering leader and principal, Deloitte & Touche LLP With innovative data protection leveraging device-level secure microcontainer technology, Zero Trust Access helps protect infrastructure while also enabling organizations to protect sensitive enterprise data and enforce least privilege through dynamic access control to enterprise assets. The managed service can replace remote access solutions inclusive of virtual private network (VPN), virtual desktop infrastructure (VDI), and desktop as a service (DaaS), all of which typically require significant capital expenditure for infrastructure, high operating costs, and technology management overhead. Zero Trust Access includes features such as ephemeral connectivity built upon secure peer-to-peer (P2P) communication, conditional access and continuous authorization, as well as robust data protection for data at-rest, in-use, and in-transit are consistently applied to each session, regardless of the type or location of the applications being accessed (e.g., legacy hosted applications, software as a service (SaaS), thick-client, web-based applications). Implementation of Zero Trust Access can help organizations leverage outcome-based solutions that improve business agility, enhance user productivity, and reduce cost and complexity of security operations. "Beginning zero trust adoption isn't simple, fast or easy for most organizations," Deborah Golden, Deloitte Risk & Financial Advisory Cyber and Strategic Risk leader and principal, Deloitte & Touche LLP. "We're launching Zero Trust Access as the first in many adoption-enabling services and solutions to come, so that our clients are better able to modernize their security programs, enable agile operations and confidently advance with emerging technologies and transformative risk management principles that can build more resilient security practices."
