This article highlights key challenges associated with offering cyber range training using AWS. It also presents Ravello cybersecurity lab as a way to run cyber ranges for training on public cloud (AWS & Google cloud) to overcome these challenges.
If you’re getting to the point where the training capacity in your datacenter is insufficient, or on the contrary – you find that there is severe under-utilization of hardware that’s just lying there – you might consider a different option: migrating virtual training environments from VMware to AWS. By doing so you will increase your training infrastructure efficiency, you will not waste capacity, and you will gain other benefits – like geographical flexibility, fast environment provisioning, cloud economics, and more.
Colocation with third-party network elements/servers in demilitarized zone (DMZ) is an issue for security architects and puts pressure on network security architecture. How do we connect third party equipment to inhouse security appliances in a flexible way? This is an issue for many large financial & health care institutions, and other enterprises that have to securely connect 3rd party equipment.
Financial institutions and enterprises require flexible network security architecture to accommodate external network devices/servers in their DC/colo facilities. This article provides a way to design and implement such a network security architecture using Border Gateway Protocol (BGP) + VXLAN tunnels along with VM-series firewall from Palo Alto Networks. Ravello Network Smart Labs provides an easy way to test and deploy an architecture before moving it to the enterprise infrastructure.
A productive training process is key to the success of new products (from internal training to channel partners and customers). Since ILT also involves a substantial investment, it isn’t surprising that more and more training organizations are seeking to understand instructor led training best practices – essentially – what they can do to maximize the effectiveness of their training sessions. At Ravello we believe that the essentials are: easily provisioned and deployed isolated full-featured product environments for each student anywhere and anytime, where the instructor and student can collaborate.
Have you ever used an unsecured public wifi connection and wondered if someone could be hacking you? Who could possibly be interested in monitoring your browsing activity on the web? In this post, we focus on a particularly active and common type of network hacking – man-in-the-middle (MITM) attacks. Network security testing is essential to discover these attacks, and Ravello cybersecurity labs provide an easy way to replicate enterprise environments on AWS and Google cloud and carry out MITM security testing.
In the previous post in the pentest on AWS and Google series, we set up a complete security testing environment to play with. As you have seen, it really isn’t that difficult for an attacker to pwn your network. A lot of what attackers do is observation, trial-and-error, and guesswork. I left most of those parts out of the article, but bad network cleanliness and practices make things a lot simpler for adversaries.
This next post in the network penetration testing lab series will get you acquainted with the technical details of the pentest blueprint and settings required to test security capabilities and run pentesting on AWS or Google Cloud.

This blog shows how to install and create Windows containers on AWS or Google using Ravello, with an example. Ravello’s nested virtualization technology allows you to deploy existing data center workloads on leading public clouds. Our earlier blogs show you how to install Windows XP, Windows 7 or Windows 8 on AWS or Google using an ISO. This blog post guides you step-by-step explaining how to install Windows 2016 on AWS/Google, how to optimize performance using the correct device drivers, how to install Windows Container role, configure networking and configure Windows containers.
Network and data-center architects are evaluating network virtualization solutions to bring workload agility to their data-centers. This article (part 3 of a 3 part series) details how to setup fully-functional VMware NSX and Cisco Nexus 1000v deployment on Ravello to evaluate each of the solutions. Part 1 compares the architectural components of Cisco Nexus 1000v and VMware NSX, and Part 2 looks into the capabilities supported by of each.
With SDDC (Software Defined Data Center) gaining prominence, network architects, administrators and data-center experts in enterprises around the globe find themselves staring at the inevitable question – should I go for vSphere environment with Cisco Nexus 1000v or VMware’s NSX as the network virtualization solution that facilitates my SDDC? This article (part 2 of 3-part series) compares Cisco Nexus 1000v with VMware NSX from deployment model, components, multi-data-center support and network services perspective. Part 1 compares capabilities supported by Cisco Nexus 1000v and VMware NSX, and Part 3 walks through how to setup a fully functional environment of each on Ravello Networking Smart Labs (powered by nested virtualization and networking overlay).
Network virtualization brings many benefits to the table – reduced provisioning time, easier/cheaper network management, agility in bringing-up of sophisticated deployments to name a few. A large number of network and data-center architects around the globe are evaluating VMware NSX and Cisco Nexus 1000v to enable network virtualization in their data-centers. This article (part 1 of 3 part series) walks through the architectural elements of VMware NSX & Cisco Nexus 1000v, and explains how Ravello (powered by nested virtualization and networking overlay) can be used as a platform to run and deploy each of the solutions with a couple of clicks for evaluation during the decision-making process. Part 2 compares capabilities supported by Cisco Nexus 1000v and VMware NSX, and Part 3 walks through steps to create a Cisco Nexus 1000v & VMware NSX deployment on Ravello.
This blog describes how to work with OpenStack networking on Ravello Systems, which enables OpenStack lab environments in the cloud. When configuring networks in an OpenStack environment on Ravello, you are essentially setting up nested KVM and overlay networks. Ravello’s…
How to setup and run a penetration testing (pentest) lab on AWS or Google Cloud with Kali Linux, Metasploitable and WebGoat
In this blog, I describe how you can deploy Kali Linux and run penetration testing (also called pen testing) on AWS or Google Cloud using Ravello System’s nested virtualization technology. This ‘Linux/Web Security Lab’ lets you hit the ground running in a matter of minutes and start exploiting security vulnerabilities. By the way, if you haven’t already seen it, this blog by SimSpace about on-demand Cyber Ranges on Ravello is very interesting as well.
Congratulations to all the newly minted vExperts of 2016! I’d like to personally thank each and every one of you because as Corey rightly said in the announcement, “each of these vExperts have demonstrated significant contributions to the community and…
Public cloud is great. It brings to table agility, on-demand capacity, unlimited resources, global reach and most importantly ability to align costs with operational needs. More and more organizations are embracing cloud to augment their datacenter capacity or to move their existing workloads off their datacenters. As datacenter and network architects embark on this journey, they need to be aware that there are some inherent differences in the way networking works in an Amazon VPC when compared to datacenters – so that they can plan ahead.
