Network Automation: Where Does it Work?

Network automation tools abound. But getting them to work together is hard work.

Pixelfed – Part 1 – Installing

About this series

I have seen companies achieve great successes in the space of consumer internet and entertainment industry. I’ve been feeling less enthusiastic about the stronghold that these corporations have over my digital presence. I am the first to admit that using “free” services is convenient, but these companies are sometimes taking away my autonomy and exerting control over society. To each their own of course, but for me it’s time to take back a little bit of responsibility for my online social presence, away from centrally hosted services and to privately operated ones.

After having written a fair bit about my Mastodon [install] and [monitoring], I’ve been using it every day. This morning, my buddy Ramón asked if he could make a second account on ublog.tech for his Campervan Adventures, and notably to post pics of where he and his family went.

But if pics is your jam, why not … [Pixelfed]!

OSPF Convergence In a Hub and Spoke Topology

My dear friend Micheline Murphy posted an excellent question on OSPF in a Hub and Spoke topology at the Cisco Learning Network. The scenario is a Hub and Spoke topology with two Hub routers that are ABRs belonging to area 100 and area 200. SP-101 and SP-102 belong to area 100. SP-201 and SP-202 belong to area 200. The topology is shown below:

The OSPF areas are shown below:

Some facts about the setup and intent of this post:

All routers are Catalyst8000v running IOS-XE 17.6.3.
Hub routers are connected to area 0 where the prefix 198.51.100.0/24 is being advertised.
Each spoke advertises a /28 from 192.0.2.0/24.
All interfaces are point to point as the purpose is not to simulate a NBMA topology.
The intent is to verify what happens in a failure scenario but lab first shows the stable topology.

The expectation is that in a stable topology each Spoke will have two ECMP routes, one via each Hub, to the other spokes. The router SP-202 will be used to demonstrate. First let’s verify that everything is working as expected. SP-202 is a router in area 200:

Unmasking the top exploited vulnerabilities of 2022

The Cybersecurity and Infrastructure Security Agency (CISA) just released a report highlighting the most commonly exploited vulnerabilities of 2022. With our role as a reverse proxy to a large portion of the Internet, Cloudflare is in a unique position to observe how the Common Vulnerabilities and Exposures (CVEs) mentioned by CISA are being exploited on the Internet.

We wanted to share a bit of what we’ve learned.

Based on our analysis, two CVEs mentioned in the CISA report are responsible for the vast majority of attack traffic seen in the wild: Log4J and Atlassian Confluence Code Injection. Although CISA/CSA discuss a larger number of vulnerabilities in the same report, our data clearly suggests a major difference in exploit volume between the top two and the rest of the list.

The top CVEs for 2022

Looking at the volume of requests detected by WAF Managed Rules that were created for the specific CVEs listed in the CISA report, we rank the vulnerabilities in order of prevalence:

Popularity rank	Description	CVEs
1. Improper Input Validation caused Remote Code execution in Apache Log4j logging library	Log4J	CVE-2021-44228
2. Atlassian Confluence Server and Data Center Remote Code Execution Vulnerability	Atlassian Confluence Code Injection	CVE-2022-26134

Chip makers team up to take on Arm with RISC-V

Five companies that manufacture semiconductors for smartphones, automobiles and more have announced that they will form a company designed to advance the open source RISC-V architecture, in a move widely seen as being designed to reduce their dependence on licensed technology from Arm.The companies — Qualcomm, Robert Bosch, Infineon Technologies, NXP Semiconductors and Nordic Semiconductors — have yet to name this joint venture, but said in a statement issued Friday that the company will be registered in Germany, and that its focus will be on providing reference architectures and establishing industry solutions. The initial focus, according to the statement, will be on the automotive industry, but plans are in place to expand into mobile and IoT use cases.To read this article in full, please click here

Hedge 189: Data Center Careers with Carrie Goetz

When network engineers think of a data center, we think of fabrics and routers and switches. There is a lot more to a data center, though—there is power, building construction, environmentals, and a lot of others. What possible jobs are out there in the data center space for people who want to work in IT, but don’t either want to code or build networks? Carrie Goetz, author of Jumpstart Your Career in Data Centers joins Tom Ammon and Russ White to tell us about a few, and about the importance of other careers in the data center.

DNSOP at IETF117

After the flurry of work in various aspects of DNS privacy, the IETF’s agenda for DNS has shifted towards more maintenance and update. This does not mean that the volume of work has abated in any way, but it has dropped the more focussed stance of previous meetings to a broader diversity of topics in operating DNS infrastructure.

IEPG at IETF117

The IEPG meets for a couple of hours before each IETF meeting. It's a somewhat eclectic collection of presentations, with some vague common thread of relevance to Internet operations. Here's a summary of my impression from these IEPG session presentations for IETF 117.

Using Web Application Firewall at container-level for network-based threats

The microservices architecture provides developers and DevOps engineers significant agility that helps them move at the pace of the business. Breaking monolithic applications into smaller components accelerates development, streamlines scaling, and improves fault isolation. However, it also introduces certain security complexities since microservices frequently engage in inter-service communications, primarily through HTTP-based APIs, thus broadening the application’s attack surface. This scenario is similar to breaking a chunk of ice into smaller pieces, increasing its surface area. It is crucial that enterprises address these security challenges before benefiting from adopting a microservice architecture.

Challenges implementing defense-in-depth for containers with perimeter-based Web Application Firewall

Kubernetes is the de-facto standard for microservices orchestration. However, as organizations increasingly adopt Kubernetes, they run the risk of inadvertently introducing security gaps. This is often the result of attempts to integrate traditional security tooling into a cloud-native ecosystem that is highly dynamic, ephemeral, and non-deterministic. Instead of implementing security around the platform, DevOps, security, and platform teams must look at enforcing defenses through the platform.

Let’s look at an example of a web application firewall (WAF) which is typically deployed at the ingress of a network or application. As shown in the diagram below, HTTP traffic is Continue reading
