Zero-day defects exist in every projects, whether they are open or closed source. John Fraizer and Alistair Woodman join Tom Ammon and Russ White to discuss an old defect John found in the FRR code, the history of this defect, and the problems inherent in finding and resolving defects in large, diverse code bases.
One of the great advantages of combining GitOps with Ansible is that you get to streamline the automation delivery and the lifecycle of a containerized application.
With the abilities of GitOps we get to:
Standardize configurations of our applications.
Inherit the benefits of version control of our configurations.
Easily track changes of the configuration settings making fixing issues easier.
Have one source of truth for our applications.
Combine the above with Ansible and you have everything you need to accomplish configuration consistency for a containerized app anywhere that you automate.
That leads us to, “how do we combine Ansible and GitOps to manage the lifecycle of a containerized application?”
Simple. By creating an Ansible workflow that is associated with a Git webhook that is part of my application’s repository.
What is a Git webhook you ask?
Git webhooks are defined as a method to deliver notifications to an external web server whenever certain actions occur on a repository.
For example, when a repository is updated, this could trigger an event that could trigger CI builds, deploy an environment, or in our case, modify the configuration of our containerized application.
A webhook provides the ability to execute specified Continue reading
Welcome to our 2022 Q2 DDoS report. This report includes insights and trends about the DDoS threat landscape — as observed across the global Cloudflare network. An interactive version of this report is also available on Radar.
In Q2, we’ve seen some of the largest attacks the world has ever seen including a 26 million request per second HTTPS DDoS attacks that Cloudflare automatically detected and mitigated. Furthermore, attacks against Ukraine and Russia continue, whilst a new Ransom DDoS attack campaign emerged.
The Highlights
Ukrainian and Russian Internet
The war on the ground is accompanied by attacks targeting the spread of information.
Broadcast Media companies in the Ukraine were the most targeted in Q2 by DDoS attacks. In fact, all the top five most attacked industries are all in online/Internet media, publishing, and broadcasting.
In Russia on the other hand, Online Media drops as the most attacked industry to the third place. Making their way to the top, Banking, Financial Services and Insurance (BFSI) companies in Russia were the most targeted in Q2; almost 45% of all application-layer DDoS attacks targeted the BFSI sector. Cryptocurrency companies in Russia were the second most attacked.
Bem-vindo ao nosso relatório de DDoS do segundo trimestre de 2022. Este relatório inclui informações e tendências sobre o cenário de ameaças DDoS — conforme observado em toda a Rede global da Cloudflare. Uma versão interativa deste relatório também está disponível no Radar.
A guerra no terreno é acompanhada por ataques direcionados à distribuição de informações.
Empresas de mídia de radiodifusão na Ucrânia foram as mais visadas por ataques DDoS no segundo trimestre. Na verdade, todos os seis principais setores vitimados estão na mídia on-line/internet, publicações e radiodifusão.
Por outro lado, na Rússia, a mídia on-line deixou de ser o setor mais atacado e caiu para o terceiro lugar. No topo, estão empresas como bancos, serviços financeiros e seguros (BFSI, na sigla em inglês) do país, que foram as mais visadas no segundo trimestre; Continue reading

Willkommen zu unserem DDoS-Bericht für das zweite Quartal 2022. Darin beschreiben wir Trends hinsichtlich der DDoS-Bedrohungslandschaft, die sich im globalen Cloudflare-Netzwerk beobachten ließen, und die von uns daraus gezogenen Schlüsse. Eine interaktive Version dieses Berichts ist auch bei Radar verfügbar.
Im zweiten Quartal haben wir einige der größten Angriffen aller Zeiten registriert, darunter eine HTTPS-DDoS-Attacke mit 26 Millionen Anfragen pro Sekunde, die von Cloudflare automatisch erkannt und abgewehrt wurde. Neben fortgesetzten Angriffen auf die Ukraine und Russland hat sich zudem eine neue Ransom-DDoS-Angriffskampagne entwickelt.
Die wichtigsten Erkenntnisse auf einen Blick
Das Internet in Russland und der Ukraine
Der Krieg wird nicht nur physisch, sondern auch in der digitalen Welt ausgefochten. Dort zielen die Angriffe darauf ab, die Verbreitung von Informationen zu verhindern.
In der Ukraine waren im zweiten Quartal Rundfunk- und Medienunternehmen das häufigste Ziel von DDoS-Angriffen. Tatsächlich sind die sechs am stärkten betroffenen Branchen alle den Bereichen Online-/Internetmedien, Verlagswesen und Rundfunk zuzurechnen.
Demgegenüber sind in Russland die Online-Medien unter den Angriffszielen auf den dritten Platz zurückgefallen. Spitzenreiter war das Segment Banken, Finanzdienstleistungen und Versicherungen (Banking, Financial Services and Insurance – BFSI). Fast 50 % aller DDoS-Angriffe auf Anwendungsschicht richteten sich gegen diese Sparte. Am zweithäufigsten wurden in Russland Continue reading

Most IT executives are probably familiar with the concepts of DevOps and DevSecOps. There’s a new model generating considerable buzz that is particularly relevant to networking professionals: NetDevOps.As with other emerging technologies, the definition of NetDevOps varies depending on who is providing it. But at a basic level, the term refers to the application of DevOps principles to computer networking.“NetDevOps is a pretty hot [and] hyped topic,” says Andrew Lerner, research vice president for networking at Gartner. “But the first question is, what is it, as there are different definitions and perceptions.”How to choose an edge gateway
What is NetDevOps?
Under the Gartner definition, NetDevOps entails applying the DevOps concepts of continuous integration/continuous deployment (CI/CD) to networking activities. Other terms used to describe this model include NetOps 2.0, network as code and GitOps networking, Lerner says.To read this article in full, please click here

File names on Linux systems can be as long as 255 characters. While determining which files in a directory have the longest names might not be the most exciting task at hand, doing this with a script poses some interesting challenges that invite equally interesting solutions.To start, consider passing the output of the ls command, which is used to list files, to a wc command that counts the characters like this:$ ls myreport.txt | wc -c
13
If you counted the letters in “myreport.txt” by looking at “myreport.txt”, you likely noticed that there are 12, not 13 letters in that file name. This is because, just as in the command below, echo sends the requested text through the pipe along with a newline character at the end.To read this article in full, please click here

The Great Re-Evaluation has brought a renewed focus on hiring practices. Candidates expect more from the entire interview, hiring, and onboarding process.
Cloudflare operates in more than 270 cities in over 100 countries, where we interconnect with over 10,000 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions. In many cases, these disruptions can be attributed to a physical event, while in other cases, they are due to an intentional government-directed shutdown. In this post, we review selected Internet disruptions observed by Cloudflare during the second quarter of 2022, supported by traffic graphs from Cloudflare Radar and other internal Cloudflare tools, and grouped by associated cause or common geography.
Optic outages
This quarter, we saw the usual complement of damage to both terrestrial and submarine fiber-optic cables, including one that impacted multiple countries across thousands of miles, and another more localized outage that was due to an errant rodent.
Comcast
On April 25, Comcast subscribers in nearly 20 southwestern Florida cities experienced an outage, reportedly due to a fiber cut. The traffic impact of this cut is clearly visible in the graph below, with Cloudflare traffic Continue reading
