Swiss Army knives are the quintessential symbol for an all-in-one device. But really they are only as good as the functions that were thought up ahead of time, then added once and for all to the knife. If you don’t buy the one with the scissors, then there’s no adding scissors later on when you need them. Network security is no different. Fixed function firewalls, fixed function routers, load balancers and packet brokers are all feature rich but only if the manufacturer designed the feature in (and you pay to turn it on). Handy up until now but not sustainable going forward.
Corsa has been working for a while to create a better way to add flexible, dynamic, adjustable security to your network. It’s all built on SDN principles and harnesses the dynamic power of SDN service chaining to build out network security that provisions functions virtually – at any scale. I recently had the opportunity to discuss Corsa with TAG Cyber‘s Ed Amoroso and it took less than 5 minutes for him to get it. For him, Corsa is a software-defined firewall solution. His article is here and it will make you think about the practicality of Swiss Army knives going forward.
Network architects and security engineers are challenged to ensure their networks always operate with integrity and are properly protected. They are looking to be proactive in their approach to network security by taking all of the information gleaned from leading network performance and analytics solutions, matching it against policy and then in real-time, updating traffic flow and network configuration (yes, I have to say leveraging AI… (more…)
I always enjoy watching the predictions columns appear towards the end of a calendar year. We made ours and they are out there for you to review (think network security and vulnerabilities). Two places worth checking out are (more…)
I was at TechEx last week in beautiful San Francisco. Despite the smell of smoke from the (more…)
DDoS attacks against Customers are the top security threat facing service providers today. These attacks, however derogatory, also present an opportunity: (more…)
Today’s networks have diverse user groups with individual requirements. Think about a service provider network, campus or research network – the interest groups using them are all over the map, literally and figuratively. (more…)
Program helps partners deepen DDoS mitigation and SDN expertise
At Corsa Technology we have recently launched our ‘Universal’ Partner Program. (more…)
In part 1 and part 2 of this series on DDoS protection, we addressed the core deficiencies with traditional mitigation solutions such as rigid ASIC, unscalable NPUs, inadequate packet parsing and too much state. All these things by themselves drag down a solution. (more…)
Volumetric DDoS attacks using hijacked IoT devices are growing at an alarming rate. There are billions of IoT devices worldwide so no lack of soldiers to muster for an attack. (more…)
I am catching up on my reading and just read the 4th quarter Akamai report on the state of the internet. For those of us who follow information security, it provides a fascinating, and ultimately, harrowing look into the current state of mega DDoS attacks. Here is what struck me … (more…)
In part one of this series, we looked at how existing DDoS mitigation techniques lag when combined with traditional routing gear. They are unable to adapt to the fast-moving landscape to defend against DDoS attacks. (more…)
Tuesday evening, September 20, 2016, was a warm, rainy day in Northern Virginia that had given no hint of what was to come. And then, at 8:00 pm, BOOM! The biggest distributed denial of service (DDoS) attack the world had ever seen (more…)
Protecting networks at scale is hard. If every provider had only a few 1G links, the existing solutions might indeed be sufficient for another few years. But 1G connections are not the norm these days. Providers are packed with 10G and 100G links (more…)
In the past, cybercriminals lurked in the dark shadows of the Internet quietly scanning target systems, evading detection eventually to launch a silent attack. The era of silent attacks has evolved to tidal waves of volumetric traffic coming from literally everywhere and everything, hitting like a ton of bricks. (more…)
What is going on in the world of DDoS protection that has high volume network and security operations scrambling to find a solution that actually works? Today’s threat landscape is intensifying, and it’s not going away anytime soon. The number of infected Internet of Things (IoT) devices continues to surge with the release of the Mirai source code and appearance of the Leet Botnet. (more…)
As we head into 2017, Corsa has gathered our predictions for what we expect to see in networking in the New Year. From security in the control/data plane to open source SDN, these are the trends we see in the market and how they might impact network functionality and scalability in 2017. Give them a read and let us know what you think in the comments. (more…)
Hardware has become the networking professional’s arch nemesis. Providers are spending more money and resources to install and maintain hardware, but end up using a fraction of the new systems’ capabilities. SDN promises to replace this burden and waste with an autonomous network that flexes and bends at the command of global control to offer dynamic networks for new service delivery. (more…)
I just got back from a week in The Hague as both an attendee and an exhibitor at the 5th annual SDN World Congress. My first observation is that the name of this show struggles to keep up with what’s actually happening (more…)
Gartner’s Andrew Lerner, who covers enterprise networking products including SDN, participated in a session on SDN at the most recent Gartner IOM conference in Orlando. (more…)
We all live SDN vicariously through Google building extremely large scale out routing. But in the real world of networking, SDN makes a difference in automatic, dynamic, policy-driven network slicing, multi-domain QoS, and per flow traffic engineering in a myriad of internet scale deployments besides the hyper-scale poster child. (more…)
If you missed us at the TNC16 Conference in Prague, you can still see what we shared on operationalizing SDN. (more…)
Harnessing Open Source Orchestration and Control Plane Software with Data Plane Hardware to Create a Networking Solution
Today’s SDN network architects are now able to source open hardware and software that is beginning to meet the various needs of their architectures. (more…)
I’ve spent the last few blogs building up Corsa’s vision for SDN where the right combination of performance, flexibility, scale and open programmability lead to a hardware platform that genuinely shifts how we do networking.
Now I’d like to introduce a further evolution of this networking change. (more…)
Google “SDN” and you’ll find a number of excellent resources like this page on Tech Target’s SearchSDN that explain the key objective of software-defined networking is to deliver cost-effective automated orchestration of networks that matches the level of automation and performance in cloud computing. But that’s a philosophy, not a solution. (more…)
There are three attributes network architects must incorporate when designing networks for organizations like service providers, ISPs and backbone networks that routinely run multiple 100G connections: scale, performance and flexibility. (more…)
Today is the day SDN realizes its potential.
This morning we launched the Corsa DP2000 series, our new open SDN switching and routing platform that redefines how network operators deliver subscriber-level networking, on-demand services and real-time (more…)
In real estate, when it is time to sell a house with an unfinished basement, or a kitchen that is falling apart, one uses the term “ready for your creative design”. It is a method for turning a negative into a positive. There is a curious similarity to this positioning within the SDN marketplace. (more…)
SDN is the boldest and most exciting concept in networking in recent years. It began with the premise that in the post-ATM / MPLS era we had become bogged down for two reasons. (more…)
