Cisco warns of critical vulnerability in virtualized network software

May 5, 2022 TH Author Network Security, Security, virtualization

Multiple vulnerabilities have been discovered in Cisco’s Enterprise NFV Infrastructure Software (NFVIS). The worst of the vulnerabilities could let an attacker escape from the guest virtual machine (VM) to the host machine, Cisco disclosed. The other two problems involve letting a bad actor inject commands that execute at the root level and allowing a remote attacker to leak system data from the host to the VM.NFVIS is Linux-based infrastructure software designed to help enterprises and service providers to deploy virtualized network functions, such as a virtual router, firewall and WAN acceleration, Cisco stated.To read this article in full, please click here READ MORE HERE…

VMware plan disaggregates servers; offloads network virtualization and security

September 29, 2020 TH Author Data Center, Security, virtualization

VMware is continuing its effort to remake the data center, cloud and edge to handle the distributed workloads and applications of the future.At its virtual VMworld 2020 event the company previewed a new architecture called Project Monterey that goes a long way toward melding bare-metal servers, graphics processing units (GPUs), field programmable gate arrays (FPGAs), network interface cards (NICs) and security into a large-scale virtualized environment.Monterey would extend VMware Cloud Foundation (VCF), which today integrates the company’s vShphere virtualization, vSAN storage, NSX networking and vRealize cloud management systems to support GPUs, FPGAs and NICs into a single platform that can be deployed on-premises or in a public cloud.To read this article in full, please click here READ MORE HERE…

Essential things to know about container networking

March 9, 2020 TH Author Networking, Security, virtualization

Containers have emerged over the past several years to provide an efficient method of storing and delivering applications reliably across different computing environments. By containerizing an application platform and its dependencies, differences in OS distributions and underlying infrastructures are abstracted away. Networking has emerged as a critical element within the container ecosystem, providing connectivity between containers running on the same host as well as on different hosts, says Michael Letourneau, an IT architect at Liberty Mutual Insurance. “Putting an application into a container automatically drives the need for network connectivity for that container,” says Letourneau, whose primary focus is on building and operating Liberty Mutual’s container platform.

SDNs and NFV are complementary and core components of modernized networks

June 5, 2018 TH Author Networking, SDN, Security, virtualization

The terms software defined networking (SDN) and network functions virtualization (NFV) are often used interchangeably, which is incorrect. In a sense, the two are tied together as companies start using NFV as part of their SDN plans but that doesn’t have to be the case.Enterprises could maintain their current network architecture and shift to NFV or they could roll out an SDN and never leverage the benefits of NFV, so it’s important to understand what each is and the benefits of both.[ For more on SDN see where SDN is going and learn the difference between SDN and NFV. | Get regularly scheduled insights by signing up for Network World newsletters. ]
What is software-defined Networking
SDNs are a fundamentally different way to think about networks. Technically, SDNs can be defined as the separation of the management, control and data-forwarding planes of networks. Many people, including technical individuals read that definition and say, “So what?”, but the separation of these planes has a profound impact on networks and enables things that have never been done before.To read this article in full, please click here READ MORE HERE…
