What is Cisco ACI?

Hello World This is an overview of what I think Cisco ACI actually is. It uses some examples from the lab environment to show you how the things look like when you start to work with ACI. There are other articles in the works which will be online soon and which will go in details through the real configuration of ACI and best practices while doing it. What is this Cisco ACI Fabric? Cisco ACI is a datacenter network Fabric. It actually means that it is a networking system of more networking L3 switches that have a modified, next-generation OS

Onward & Upward: Recapping NSX-T in 2018 and Beyond

Overview

2018 was a big year for NSX-T Data Center, VMware’s network virtualization platform designed and optimized for application workloads running on both vSphere and non-vSphere environments, container platforms, and public clouds. In addition to supporting core use cases around security, automation, and multi-cloud networking, NSX-T Data Center has continued to expand the capabilities of the platform to include enabling networking and security for emerging use cases around containers and cloud-native applications. To support these use cases and increasingly deliver value to customers, NSX-T Data Center saw new versions released, improvements made to plug-ins, and integrations across an expanding ecosystem. 2018 also saw NSX-T Data Center gain significant momentum in terms of customer adoption, delivering enhanced and new capabilities across all use cases to a quickly growing number of customer deployments.

In June, NSX-T Data Center 2.2 was released, bringing with this the ability to manage Microsoft Azure based workloads, referred to as NSX Cloud. The NSX-T Data Center platform was also updated to provide networking and security infrastructure for VMware Cloud on AWS. Other notable capabilities included enhanced data path mode in N-VDS, an improved controller cluster deployment experience, guest Continue reading

First step to becoming a hacker: Linux!

If you're contemplating a career in cybersecurity and haven't come up to speed on Linux, now's the time to get ramped up and here's one easy way to do it. This new book from no starch press was written with people like you in mind. Authored by OccupyTheWeb, the force behind Hackers-Arise, Linux Basics for Hackers provides everything from basic Linux command line skills through to scripting, manipulating logging, network scanning, using and abusing system services, and remaining stealthy in the process.Why Linux? Because Linux is open source, tool developers (and you) have a level of access that is unsurpassed. Linux is transparent and this means that you can learn to manipulate it in ways that are not possible with most OSes. In addition (and undoubtedly for the reason just mentioned), most cybersecurity tools are written to run on Linux.To read this article in full, please click here

Just when you express hope that the network industry can shed the past, somebody demonstrates it won’t be easy. An interview in Light Reading with Amdocs CTO Anthony Goonetilleke proposes that one of the unsung benefits of 5G is that it will enable operators to charge for services rather than for data. Is this really a 5G revolution in making, or are we simply reprising the same kind of silly stuff that’s been around for decades? —Tom Nolle

The Silicon Valley gospel of “disruption” has descended into caricature, but, at its core, there are some sound tactics buried beneath the self-serving bullshit. A lot of our systems and institutions are corrupt, bloated, and infested with cream-skimming rentiers who add nothing and take so much. —Cory Doctorow

The high-order bit in much of the below is complexity. Hardware, software, platforms, and ecosystems are often way too complex, and a whole lot of our security, privacy, and abuse problems stem from that. —Chris Palmer

How much of the internet is fake? Studies generally suggest that, year after year, less than 60 percent of web traffic is human; some years, according to some researchers, a healthy majority of it is bot. For a Continue reading

Oculeus anti-fraud offering protects against telecom system abuse

When most enterprise companies worry about having their systems hacked by attackers, the main concern is for the enterprise networks. Few companies consider that their phone systems may be vulnerable to hacking resulting in costly toll fraud. Nevertheless, the practice of hacking into corporate PBX systems and injecting fraudulent calls over the network is causing billions of dollars in damage worldwide every year.Enterprise companies use modern PBX (private branch exchange) systems to run their communications. A PBX switches calls between enterprise users on local lines while allowing all users to share a certain number of external phone lines. Modern PBX systems work on the Session Initiation Protocol (SIP), which is a signaling protocol used for initiating, maintaining, and terminating real-time sessions that include voice, video, and messaging applications.To read this article in full, please click here

Orange Matter: Automation Paralysis

I’ve been blogging for Solarwinds recently, posting on Orange Matter, with a cross-post to the Thwack Geek Speak forum. This post examines how it’s easy to get so focused on automating the small stuff we have difficulty turning that into the more cohesive automation solution that we’d like to have.

This post appeared on Orange Matter as “Automation Paralysis: Why We Get Stuck Automating The Small Stuff“, but I’m also linking to the version posted on Thwack, mainly because that format allowed me to use more images and be slightly more irreverent. Irreverent? Moi? Of course.
