Claudio Jeker Honored by Internet Security Research Group with Radiant Award
This week another Radiant Award has been awarded by the Internet Security Research Group, the folks behind Let’s Encrypt. The award puts the limelight on the heroes who make the Internet more secure and trustworthy each day.
The newest Radiant Award winner is Claudio Jeker, who receives the prize for his work of a BGP4 implementation on OpenBSD. This makes me horrendously enthusiastic. Why?
OpenBSD is a open-software based operating system that is focused on being secure and feature complete. It comes with a set of tools that make it ideally suited to be deployed, for instance, as a secure route server in an Internet Exchange Point (IXP). A route server is a service that an IXP can host in order to make the participating network service providers lives a little easier. They do not have to get the routing information from each other, but can simply talk to this piece of centralized infrastructure. OpenBSD allows this type of infrastructure to be build from commodity components in a scalable and secure way.
With a route server in place, an IXP can take additional measures to secure the Internet, namely by taking the MANRS actions.
Ultimately this would not be Continue reading

New tools to monitor your server and avoid downtime
When your server goes down, it’s a big problem. Today, Cloudflare is introducing two new tools to help you understand and respond faster to origin downtime — plus, a new service to automatically avoid downtime.
The new features are:
- Standalone Health Checks, which notify you as soon as we detect problems at your origin server, without needing a Cloudflare Load Balancer.
- Passive Origin Monitoring, which lets you know when your origin cannot be reached, with no configuration required.
- Zero-Downtime Failover, which can automatically avert failures by retrying requests to origin.
Standalone Health Checks
Our first new tool is Standalone Health Checks, which will notify you as soon as we detect problems at your origin server -- without needing a Cloudflare Load Balancer.
A Health Check is a service that runs on our edge network to monitor whether your origin server is online. Health Checks are a key part of our load balancing service because they allow us to quickly and actively route traffic to origin servers that are live and ready to serve requests. Standalone Health Checks allow you to monitor the health of your origin even if you only have one origin or do not yet Continue reading
Practice Your Public Cloud Networking with Hands-On Exercises
Design assignments and hands-on exercises were always a big part of ipSpace.net online courses, and our new Networking in Public Cloud Deployments course is no different.
You’ll start with a simple scenario: deploy a virtual machine running a web server. Don’t worry about your Linux skills, you’ll get the necessary (CCIE-level) instructions and the source code for the web server. Building on that, you’ll create another subnet and deploy another virtual machine acting as a back-end application server.
And then we’ll get to the fun part:

At the heart of any reasonably sized network, should be a solid strategy around flow collection, querying and visualization. Proper use of flow logs are crucial to SecOps/NetOps from triaging attacks to capacity planning and traffic trending. I remember some 20 years ago, the first time I saw flow logs being visualized in rrdtools it was pretty close to magic. ...

Network inventory: what do you have, and should it be there?
How do you defend what you don’t know exists? In IT, this is more than just an existential question, or fuel for a philosophical debate. The existence of a complete network inventory—or the lack thereof—has a real-world impact on an organization’s ability to secure their network. Establishing and maintaining a network inventory is both a technological and a business process problem, and serves as an excellent example of the importance of open standards to a modern organization.
Consider for a moment NASA’s Jet Propulsion Laboratory (JPL). In April 2018 the JPL experienced a cybersecurity event. Upon investigation, it was determined that this was caused by someone smuggling an unauthorized Raspberry Pi onto the premises and connecting it to the network.
This incident triggered a security audit, and the results of that June 2019 report were, though not unexpected, still rather disappointing. The auditors’ biggest concern was that the JPL didn’t have a comprehensive, accurate picture of what devices were on its networks, nor did it know whether or not those devices were authorized to be there.
This lack of an up-to-date and automated network inventory led to a successful hack of the JPL via the unauthorized Raspberry Pi. Some Continue reading
