In today's security world, there are numerous security solutions that can limit access to company data and IT resources and lock down access. However, when it comes to using AI apps and their back-end models, the answer is not so simple.We speak with Carl Solder, Chief Technology Officer - Cisco Australia/New Zealand and get his insights into the challenge that Cisco saw looming on the horizon years ago and has culminated in a brand-new solution called Cisco AI Defence. Prior to this role, Carl was Cisco's Vice President of Engineering for the Enterprise Networking and Cloud Engineering organisation at Cisco HQ in San Jose, California. In this role he was responsible for Technical Strategy for the Enterprise Network and Cloud portfolio. His portfolio included the Catalyst Routing, Switching and Wireless platforms, the Intent Based Networking Software Innovations around Automation, Assurance, Machine Learning and Artificial Intelligence as well as the Policy, Identity and Segmentation Software solutions that include Cisco's Identity Services Engine (ISE).Through his time at Cisco, Carl has also held various Engineering leadership roles in Cisco HQ San Jose and served as a Distinguished Engineer working on early developments in the area of Mass Scale Data Centre Architectures, OpenFlow and Software Defined Networking. With more than 35 years of technical, business and sales leadership experience in the ICT industry, Carl has a diverse ICT background that provides great insight into emerging market transitions.Further Reading/WatchingCisco AI summit: https://www.ciscoaisummit.com/AI defence: https://newsroom.cisco.com/c/r/newsroom/en/us/a/y2025/m01/cisco-unveils-ai-defense-to-secure-the-ai-transformation-of-enterprises.htmlOWASP Top Ten vulnerabilities for AI white paper -https://genaisecurityproject.com/resource/owasp-top-10-for-llm-applications-2025/#Cisco #AIdefence #mysecuritytv
Adi Jagannathan, the CEO and co-founder of OpenFlow, joins the show to talk about OpenFlow's journey from being a CRM software and industry agnostic firm to deeply specializing in the cannabis and dispensary industry. Adi shares the challenges he faced while operating agnostically, the evolution of his agency's business model, and how his category specialization (RevOps), industry specialization (cannabis), and software specialization (HubSpot) came to be. He also shares the unique opportunities that are present within the cannabis industry—especially around CRM, customer platforms, and the power of integrating dispensary point of sale data with customer data.
Software-Defined Networking (SDN) wird oft als eine weitreichende Umwälzung im Internet beschrieben, an der wir beide nicht ganz unbeteiligt waren. In dieser Episode von Neulich im Netz analysieren wir die technische Motivation und ökonomischen Triebkräfte bei der Entwicklung und Adoption von OpenFlow – der SDN-Kerntechnologie – und erläutern die grundlegenden Prinzipien, Vorteile und mögliche Probleme. Hat SDN, und OpenFlow insbesondere, die Versprechungen gehalten? Wir werden diese Technologien heute eingesetzt und wer sind die treibende Kräfte? Diese und weitere Fragen diskutieren wir in dieser Folge von Neulich im Netz. Mehr zu Neulich im Netz auf https://www.neulich-im.net/ music by scottholmesmusic.com Quellen: Martin Casado, Michael J.

Pour ce 23e épisode, je reçois Olivier Wenin pour son initiative OpenFlow. Olivier Wenin est ingénieur civil et a passé la plus grande partie de sa carrière dans des moyennes et grosses organisations. C'est après s'être vu poser la question de ce qu'il faisait comme travail par ses enfants qu'il s'est rendu compte que la réponse qu'il leur donnait n'était pas satisfaisante à ses yeux. Et pourtant, c'était sympa : "Je construis des robots dans le domaine pharmaceutique..." Mais Olivier Wenin s'est remis en question en se demandant à quoi il contribuait réellement. Une idée trottait dans sa tête après plusieurs lectures. Mutualiser les ressources et penser le monde de demain. Il a donc créé Open Flow. Open Flow est une coopérative qui regroupe des personnes qui ont envie de contribuer à la transition des entreprises. Comment ? En accompagnant la transition dans les entreprises vers un mode plus durable. En incubant des projets à impacts sociétaux positifs. En développant une communauté qui réfléchisse au monde de demain. Lors de la crise du coronavirus, Olivier Wenin et Open Flow ont pu démontrer que ce n'était pas qu'un rêve, mais bien une initiative concrète. En effet, ils ont créé « UV Flash » et « Namur Boutik ». Pour en savoir plus, écoutez l'épisode. Olivier Wenin y explique bien mieux que moi comment tout ça fonctionne de manière hyper agile et vertueuse ! Dans cet épisode, on parle de : UVFlash Namur Boutik Fabian Gillard et le Sport2Gether Start.Lab Fabian Pinckaers et Odoo APM Pablo Servigne Elon Musk Neuralink Blockchain Tom Nixon - Work with source Frédéric Laloux - Reinventing Organizations
На линкмитапе у меня состоялся любопытный диалог про SDN и контроллеры - У нас SDN. - SDN? Серьёзно? Фу-фу-фу. И стало понятно, что не для всех SDN - это объективная реальность уже без малого лет 10. А тут и тема уже назрела - оверлейные сети. Про что: Истоки и история Про оверлейные сети и SDN vrouter/vswitch/vfirewall/vhub/vbridge Openflow vs BGP vs XMPP vs gRPC Почему нельзя взять open source и 1 человека на поддержку?

This podcast introduction was written by Nick Buraglio, the host of today’s podcast. In the original days of this podcast, there were heavy, deep discussions about this new protocol called “OpenFlow”. Like many of our most creative innovations in the IT field, OpenFlow came from an academic research project that aimed to change the way that we as operators managed, configured, and even thought about networking fundamentals. For the most part, this project did what it intended, but once the marketing machine realized the flexibility of the technology and its potential to completely change the way we think about vendors, networks, provisioning, and management of networking, they were off to the races. We all know what happened next.Read more …

Software-defined networking (SDN) is an approach to create a centrally controlled programmable packet network. Any protocols with the same approach could be considered as SDN as well.For open protocols, we have one popular standard protocol “OpenFlow” talking among the central controllers to all managed networking devices. Open Network Foundation (ONF) defines OpenFlow protocol.In fact, vendors also have developed proprietary protocols to implement this same approach. For example, Cisco’s ACI is a proprietary SDN solution.Here I summarize 3 most probable scenarios when we deploy SDN.Scenario 1: Open protocol, open multiple vendorsSince OpenFlow protocol from ONF is open, any vendors can develop inter-operable software and hardware products. For enterprise customers, the first natural approach is to buy from multiple networking venders.For example, controllers from vendor A, some switches from vendor B, some routers from vendor C, and so on and so forth.The most obvious benefit of this scenario is lower buying cost. Enterprises can buy any compatible networking products from any vendors in the market with the lowest price. White-brand, or no-brand vendors have opportunities to compete on price against existing networking vendors.However, only the buying cost is lower. We also must consider other costs to build and maintain a working network. Integration of software and hardware itself is a heavy project.When we already have a capable team of hardware and software integration, we can work comfortably with this approach. If we simply don’t have such a “Tiger Team”, or we are just about to create a team from scratch, this scenario could be difficult and costly. It could cancel out all benefits of lower buying cost.Scenario 2: Open protocol, one major vendorSome vendors are capable to provide all components for OpenFlow. For example, Cisco. In this scenario, basically we buy controllers and network devices from single major vendor. For less important areas, we buy some from other venders in the market.In this approach, we might have higher buying costs. Because we now have a major vender, we can gain better support from that major vendor. We can also achieve less integration cost because our team have fewer combinations of products to experiment and integrate with. We don’t need a huge team like previous scenario.I am more familiar with Cisco. Let me summarize what Cisco can provide for OpenFlow.“Cisco Open SDN Controller” is OpenFlow protocol controller. The software is a commercial distribution of OpenDaylight by OpenDaylight open source project. This software is packaged as a virtual machine format.In addition, Cisco’s Nexus 3000 and 9000 family switches can run “Cisco OpenFlow Agent” inside to become OpenFlow switches so they can be controlled by standard OpenFlow controllers.We can deploy OpenFlow by simply selecting all components from Cisco. Because OpenFlow protocol is open, we also have the flexibility to add non-Cisco but OpenFlow compatible devices.Scenario 3: Close protocol, one vendorSome vendor can provide all features and benefits of “centrally controlled programmable packet network”, with proprietary protocol. For example, again, Cisco.Cisco’s Application Centric Infrastructure (ACI) is Cisco’s proprietary SDN solution. With Cisco’s ACI, we can achieve even more than OpenFlow such as:Device managementBetter integration with non-networking devices such as Layer 7 switches and stateful firewallsBetter programmer-friendly abstraction instead of VLANs and subnets.In this scenario, we have the highest buying cost and we are locked into single vendor. However, we have the lowest integration cost and we now have full support from that single vendor. We only need an even smaller support team and concentrate all resources on using the network instead of experimenting interoperability among vendors.One more thing…Winter flowers near Taoyuan High Speed Rail Station.SDN is a promising approach for next generation networking. Programmable network indeed is the foundation for network automation.On the other hand, I don’t think it fits well for all types and sizes of customers. Let me talk more about who needs SDN in the coming posts.I am Li-Ji Hong. This is my blog “Show IP Protocols”. See you next time!

Is the CCIE still relevant? Are CCNA, CCNP and CCIE certs even worth it? Surely SDN and Network Automation are replacing certifications? The CCIE is no longer worth it as networks will be automated. Right? With SDN and network automation, there is no longer a need for CCNA, CCNP or CCIE certifications. Jeff McLaughlin, Director, Technical Marketing at Cisco tells us his thoughts on this. He also explains SD-Access (SDA) and other Cisco SDN technologies. Menu: Who is Jeff: 00:24 The CCIE is dead: 2:20 Is Networking still a good career?

How Intel docs were misinterpreted by almost any OS, a look at the mininet SDN emulator, do’s and don’ts for FreeBSD, OpenBSD community going gold, ed mastery is a must read, and the distributed object store minio on FreeBSD. Headlines Intel documentation flaw sees instruction misimplemented in almost every OS A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs. + A detailed white paper describes this behavior here + FreeBSD Commit Thank you to the MSRC Incident Response Team, and in particular Greg Lenti and Nate Warfield, for coordinating the response to this issue across multiple vendors. Thanks to Computer Recycling at The Working Center of Kitchener for making hardware available to allow us to test the patch on additional CPU families. + FreeBSD Security Advisory + DragonFlyBSD Post + NetBSD does not support debug register and so is not affected. + OpenBSD also appears to not be affected, “We are not aware of further vendor information regarding this vulnerability.” + IllumOS Not Impacted Guest Post – A Look at SDN Emulator Mininet A guest post on the FreeBSD Foundation’s blog by developer Ayaka Koshibe At this year’s AsiaBSDCon, I presented a talk about a SDN network emulator called Mininet, and my ongoing work to make it more portable. That presentation was focused on the OpenBSD version of the port, and I breezed past the detail that I also had a version or Mininet working on FreeBSD. Because I was given the opportunity, I’d like to share a bit about the FreeBSD version of Mininet. It will not only be about what Mininet is and why it might be interesting, but also a recounting of my experience as a user making a first-time attempt at porting an application to FreeBSD. Mininet started off as a tool used by academic researchers to emulate OpenFlow networks when they didn’t have convenient access to actual networks. Because of its history, Mininet became associated strongly with networks that use OpenFlow for their control channels. But, it has also become fairly popular among developers working in, and among several universities for research and teaching about, SDN (Software Defined Networking) I began using Mininet as an intern at my university’s network research lab. I was using FreeBSD by that time, and wasn’t too happy to learn that Mininet wouldn’t work on anything but Linux. I gradually got tired of having to run a Linux VM just to use Mininet, and one day it clicked in my mind that I can actually try porting it to FreeBSD. Mininet creates a topology using the resource virtualization features that Linux has. Specifically, nodes are bash processes running in network namespaces, and the nodes are interconnected using veth virtual Ethernet links. Switches and controllers are just nodes whose shells have run the right commands to configure a software switch or start a controller application. Mininet can therefore be viewed as a series of Python libraries that run the system commands necessary to create network namespaces and veth interfaces, assemble a specified topology, and coordinate how user commands aimed at nodes (since they are just shells) are run. Coming back to the port, I chose to use vnet jails to replace the network namespaces, and epair(4) links to replace the veth links. For the SDN functionality, I needed at least one switch and controller that can be run on FreeBSD. I chose OpenvSwitch(OVS) for the switch, since it was available in ports and is well-known by the SDN world, and Ryu for the controller since it’s being actively developed and used and supports more recent versions of OpenFlow. I have discussed the possibility of upstreaming my work. Although they were excited about it, I was asked about a script for creating VMs with Mininet preinstalled, and continuous integration support for my fork of the repository. I started taking a look at the release scripts for creating a VM, and after seeing that it would be much easier to use the scripts if I can get Mininet and Ryu added to the ports tree, I also tried a hand at submitting some ports. For CI support, Mininet uses Travis, which unfortunately doesn’t support FreeBSD. For this, I plan to look at a minimalistic CI tool called contbuild, which looks simple enough to get running and is written portably. This is very much a work-in-progress, and one going at a glacial pace. Even though the company that I work for does use Mininet, but doesn’t use FreeBSD, so this is something that I’ve been working on in my free time. Earlier on, it was the learning curve that made progress slow. When I started, I hadn’t done anything more than run FreeBSD on a laptop, and uneventfully build a few applications from the ports tree. Right off the bat, using vnet jails meant learning how to build and run a custom kernel. This was the easy part, as the handbook was clear about how to do this. When I moved from using FreeBSD 10.3 to 11, I found that I can panic my machine by quickly creating and destroying OVS switches and jails. I submitted a bug report, but decided to go one step further and actually try to debug the panic for myself. With the help of a few people well-versed in systems programming and the developer’s handbook, I was able to come up with a fix, and get it accepted. This pretty much brings my porting experiment to the present day, where I’m slowly working out the pieces that I mentioned earlier. In the beginning, I thought that this Mininet port would be a weekend project where I come out knowing thing or two about using vnet jails and with one less VM to run. Instead, it became a crash course in building and debugging kernels and submitting bug reports, patches, and ports. It’d like to mention that I wouldn’t have gotten far at all if it weren’t for the helpful folks, the documentation, and how debuggable FreeBSD is. I enjoy good challenges and learning experiences, and this has definitely been both. Thank you to Ayaka for working to port Mininet to the BSDs, and for sharing her experiences with us. If you want to see the OpenBSD version of the talk, the video from AsiaBSDCon is here, and it will be presented again at BSDCan. **iXsystems** [iXsystems LFNW Recap](https://www.ixsystems.com/blog/lfnw-2018-recap/) 10 Beginner Do's and Don't for FreeBSD 1) Don't mix ports and binary packages 2) Don't edit 'default' files 3) Don't mess with /etc/crontab 4) Don't mess with /etc/passwd and /etc/groups either! 5) Reconsider the removal of any options from your customized kernel configuration 6) Don't change the root shell to something else 7) Don't use the root user all the time 8) /var/backups is a thing 9) Check system integrity using /etc/mtree 10) What works for me doesn't have to work for you!

We've all seen the threads on mailing lits, USENET news groups and web forums about the relative merits of Emacs vs vi, including endless iterations of flame wars, and sometimes even involving lesser known or non-portable editing environments. And then of course, from the Linux newbies we have seen an endless stream of tweeted graphical 'memes' about the editor vim (aka 'vi Improved') versus the various apparently friendlier-to-some options such as GNU nano. Apparently even the 'improved' version of the classical and ubiquitous vi(1) editor is a challenge even to exit for a significant subset of the younger generation. Yes, your choice of text editor or editing environment is a serious matter. Mainly because text processing is so fundamental to our interactions with computers. But for those of us who keep our systems on a real Unix (such as OpenBSD or FreeBSD), there is no real contest. The OpenBSD base system contains several text editors including vi(1) and the almost-emacs mg(1), but ed(1) remains the standard editor. Now Michael Lucas has written a book to guide the as yet uninitiated to the fundamentals of the original Unix text editor. It is worth keeping in mind that much of Unix and its original standard text editor written back when the standard output and default user interface was more likely than not a printing terminal. To some of us, reading and following the narrative of Ed Mastery is a trip down memory lane. To others, following along the text will illustrate the horror of the world of pre-graphic computer interfaces. For others again, the fact that ed(1) doesn't use your terminal settings much at all offers hope of fixing things when something or somebody screwed up your system so you don't have a working terminal for that visual editor. DigitalOcean Digital Ocean Promo Link for BSD Now Listeners Distributed Object Storage with Minio on FreeBSD Free and open source distributed object storage server compatible with Amazon S3 v2/v4 API. Offers data protection against hardware failures using erasure code and bitrot detection. Supports highly available distributed setup. Provides confidentiality, integrity and authenticity assurances for encrypted data with negligible performance overhead. Both server side and client side encryption are supported. Below is the image of example Minio setup. Architecture Diagram The Minio identifies itself as the ZFS of Cloud Object Storage. This guide will show You how to setup highly available distributed Minio storage on the FreeBSD operating system with ZFS as backend for Minio data. For convenience we will use FreeBSD Jails operating system level virtualization. Setup The setup will assume that You have 3 datacenters and assumption that you have two datacenters in whose the most of the data must reside and that the third datacenter is used as a ‘quorum/witness’ role. Distributed Minio supports up to 16 nodes/drives total, so we may juggle with that number to balance data between desired datacenters. As we have 16 drives to allocate resources on 3 sites we will use 7 + 7 + 2 approach here. The datacenters where most of the data must reside have 7/16 ratio while the ‘quorum/witness’ datacenter have only 2/16 ratio. Thanks to built in Minio redundancy we may loose (turn off for example) any one of those machines and our object storage will still be available and ready to use for any purpose. Jails First we will create 3 jails for our proof of concept Minio setup, storage1 will have the ‘quorum/witness’ role while storage2 and storage3 will have the ‘data’ role. To distinguish commands I type on the host system and storageX Jail I use two different prompts, this way it should be obvious what command to execute and where. WeI know the FreeNAS people have been working on integrating this Best practises for pledge(2) security Let's set the record straight for securing kcgi CGI and FastCGI applications with pledge(2). This is focussed on secure OpenBSD deployments. Theory Internally, kcgi makes considerable use of available security tools. But it's also designed to be invoked in a secure environment. We'll start with pledge(2), which has been around on OpenBSD since version 5.9. If you're reading this tutorial, you're probably on OpenBSD, and you probably have knowledge of pledge(2). How to begin? Read kcgi(3). It includes canonical information on which pledge(2) promises you'll need for each function in the library. This is just a tutorial—the manpage is canonical and overrides what you may read here. Next, assess the promises that your application needs. From kcgi(3), it's easy to see which promises we'll need to start. You'll need to augment this list with whichever tools you're also using. The general push is to start with the broadest set of required promises, then restrict as quickly as possible. Sometimes this can be done in a single pledge(2), but other times it takes a few.

Paul Coggin is my SME when I need to know about anything network #security related. And this time, we wanted to have him on our show to discuss Software Defined Networking (#SDN) Software defined networking allows for applications to make connections, manage devices and even control the network using #APIs. It in effect allows any developer become a network engineer. Obviously this could be a recipe for disaster if the dev is not fully understanding of the rammifiications. And there's more good news (if you're a black hat), there's no role based security, parts of the #specification isn't fully fleshed out yet, and there are vendor specific frameworks of their own, that may not be fully interoperable with each other... Paul talks to us about some background of #SDN, some of the pitfalls and what you need to think about when implementing Software Defined Networking.

Software Defined Networking (SDN) is rapidly emerging as a technology with potential to improve network flexibility via software-based management and control. A consortium of researchers from nine universities and the CSIRO, led by UNSW and including Swinburne, has been awarded a LIEF grant by the Australian Research Council to deploy SDN equipment within each of their labs. These sites are being interconnected by AARNet to create a national wide-area SDN testbed environment, with the potential to peer internationally with testbeds in the USA, Europe and elsewhere. This testbed is helping us better understand the SDN ecosystem - Openflow-enabled hardware (Noviflow, Pica8, Corsa), controller software (Floodlight, Ryu, ONOS), application development APIs, and SDN applications themselves. Building this wide-area testbed is helping us learn the complexity, maturity, performance, and scalability aspects of carrier SDN deployment, as well as identify current gaps. The intended result is a growing store of knowledge and experience, to be shared with network operators who are potentially interested in exploring SDN solutions. In this presentation, the architecture of the SDN testbed will be presented, along with examples of the planned research experiments and potential use-cases.

We first talked about TTPs in Weekly 220 in a discussion with Curt Beckmann back in January 2015. While Curt was fairly enthused that TTPs were going to move the ball forward, Rob is not convinced that TTPs are the long-term answer to make it easier for OpenFlow controllers and switches to share capabilities. The post PQ Show 64: OpenFlow TTPs Won’t Save Us with Rob Sherwood appeared first on Packet Pushers.

Richard chats with Tom Hollingsworth about the Software Defined Network (SDN) landscape and how it's evolving into a more open set of standards that interoperate well together. Of course, it's never that easy, but one aspect that has really grabbed ahold is whitebox networking - standard hardware with custom software. Normally the two are supplied by the same vendor, but that is starting to change. Remarkably, Hewlett Packard has some leading edge aspects of this, including their own SDN App Store, so that you can choose what networking software you want to run on their hardware. And other hardware vendors while still supplying their own software are supporting OpenFlow, using the OpenFlow protocol to make highly interoperable switches. The future of SDN is very cool!
Conventional networks have been around for decades, proprietary protocols, interoperability issues have plagued network engineers to utilize multi-vendor architectures. ASIC based network switches and routers have come a long way but are reaching speed and compatibility constraints. Software Defined Networking looks to be the network architecture of the future and is being driven by customers.
