Today, we are excited to share that Cloudflare and Accenture Federal Services (AFS) have been selected by the Department of Homeland Security (DHS) to develop a joint solution to help the federal government defend itself against cyberattacks. The solution consists of Cloudflare’s protective DNS resolver which will filter DNS queries from offices and locations of the federal government and stream events directly to Accenture’s analysis platform.
Located within DHS, the Cybersecurity and Infrastructure Security Agency (CISA) operates as “the nation’s risk advisor.”1 CISA works with partners across the public and private sector to improve the security and reliability of critical infrastructure; a mission that spans across the federal government, State, Local, Tribal, and Territorial partnerships and the private sector to provide solutions to emerging and ever-changing threats.
Over the last few years, CISA has repeatedly flagged the cyber risk posed by malicious hostnames, phishing emails with malicious links, and untrustworthy upstream Domain Name System (DNS) resolvers.2 Attackers can compromise devices or accounts, and ultimately data, by tricking a user or system into sending a DNS query for a specific hostname. Once that query is resolved, those devices establish connections that can lead to malware downloads, phishing websites, Continue reading
In this episode Rick and Melchior invited Rolf Schaerer from Pensando Systems and ask him all how Pensando redefines the Netwok Server Edge.
“A New Way of Thinking About Next-Gen Cloud Architectures” leveraging a custom, programmable P4 processor Pensanso refers to as Capri. Capri is optimized to execute a software stack delivering cloud, compute, network, storage, and security services at cloud scale. Capri is easily installed in any standard server via the Pensando Distributed Services Card (DSC). The DSC provides software-defined services at the server edge, eliminating an assortment of discrete appliances throughout the data center and simplifying IT operations.
Hello my friend,
Talking to some our partners, they mentioned that they are extensively using the unit tests python libraries for the development of the software in Python. They are creating their applications in Django framework; therefore, they are using a built-in Django testing library, which is based on Python’s standard unittest. We start looking, how we can use that ourselves…

What do we, network engineers, do to quickly check that our network devices are reachable? We do ping. However, is that really good enough to check that your devices are OK? The one could say: I don’t even use a ping for that, as I rely on my NMS. This is also a good answer. In the same time, though, the vast majority of the NMS doesn’t contain all the details of network devices configuration and their operational data: e.g. all the details of OSPF and Continue reading
Enums group a related number of values and store the values internally as integers. Enums are good to use when the number of values are not too big. Considerations Enums are a type safe alternative to Symbols. It is recommended to use Enums whenever possible and only use Symbols for an...continue reading

Figure 3-1 shows the Overlay Network Control-Plane interaction. Edge-xTR-11 registers reachability information (IP address and location) of EP1 to MapSrv-22. MapSrv-22 stores the information into the Mapping database and then installs it to RIB. Then MapSrv-22 exports the information to the BGP process and sends BGP Update using VPNv4 address format to Border-PxTR-13. Border-PxTR-13 imports NLRI into BRIB and RIB. Then it sends BGP Update to the local SD-WAN edge device vEdge-1. After importing the received information into BRIB and RIB, vEdge-1 exports the information to the OMP process and advertises it over a DTLS connection to vSmart (SD-WAN Control-Plane node). vSmart, in turn, advertises information to remote SD-WAN device vEdge-2. After importing the received information into the RIB, vEdge-2 exports the information to the BGP process and sends BGP Update to Border-Leaf-13. Border-Leaf-13 installs the information into BRIB and RIB. Next, Border-Leaf-13 sends BGP Update message using EVPN route type 5 (IP Prefix Route) to its iBGP peer Spine-1 (BGP Route-Reflector) using auto-generated Route-Target 65030:10077. Spine-1 forwards the BGP Update to Leaf-1, which imports the information into L3VNI used with VRF NWKT and installs the route into the VRF NWKT RIB.
