Contributors: Jason Zhang (NSBU TAU), Stefano Ortolani (NSBU TAU)
Introduction
Formerly known as the Malware Information Sharing Platform, MISP is a leading open-source threat intelligence platform (TIP) that organizations of all sizes can leverage to store, share, and enrich threat indicators of compromise (IoCs).
The MISP ecosystem primarily comprises two parts: MISP core (or engine) and MISP modules. MISP core is responsible for the main functionality of the platform, while MISP modules were introduced to extend the capability of MISP without changing MISP core components.
Thanks to the simple API interface provided by MISP, many third-party MISP modules have been developed to greatly extend MISP’s capabilities. There are mainly three types of MISP modules: expansion modules, import modules, and export modules. More details on MISP modules can be found on MISP’s GitHub MISP module repository, which includes three modules developed by Lastline (now part of VMware) that integrate MISP with VMware NSX Advanced Threat Analyzer (ATA), as we reported earlier.
Recently VMware’s Threat Analysis Unit (TAU) developed a new expansion module, which replaces the three Lastline modules. The improvements from the new module are twofold: a simplified enrichment process and an augmented enrichment capability.

Bringing OAuth 2.0 to Wrangler
Over the course of this summer, I had the incredible opportunity to join the Workers Developer Productivity team and help improve the developer experience of Workers. Today, I’ll talk about my project to implement the OAuth 2.0 login protocol for Wrangler, the Workers command line interface (CLI).
Wrangler needs to be authorized in order to carry out its job. API tokens are one way to authorize Wrangler, but they do not provide the best user experience as the user needs to manually copy and paste their tokens. This is where the OAuth 2.0 protocol comes into play.
Wrangler login and OAuth 2.0
Previously, the wrangler login command used API tokens to authenticate Wrangler. However, managing API tokens can sometimes be cumbersome, since you need to go to the Cloudflare dashboard to create or modify a token. By using OAuth 2.0, we can allow users to directly choose permissions or scopes from Wrangler. OAuth 2.0 helps simplify the login process while making it more secure.
OAuth 2.0 is an industry-standard protocol for allowing users to authorize applications without having to share a password. In order to understand this protocol, we need to define some Continue reading
What Are Mesh Routers For Wi-Fi
There may be many reasons as to why the Wi-Fi at your house does not work. Weakened Wi-Fi signals could be a result of any physical obstruction or it can also be caused by dead spots. This is the reason as to why the Wi-Fi at your home does not work well. But what can we do to fix this problem? Is this even a problem? Yes definitely it is a problem. Weakened Wi-Fi means nothing but slow internet connectivity which means that you might not be able to join your online class on time, might miss the meeting, might not be able to send in the email to your boss or simply just experience a pause at life. In the rowing times people almost across the globe are highly dependent on Wi-Fi and internet connectivity. Having a slow internet can defiantly become a headache for many of us. The solution can be simple: a mesh router for Wi-Fi or full home Wi-Fi is the most ideal solution

Building a Small Data Center Fabric with Four Switches
One of my subscribers has to build a small data center fabric that’s just a tad too big for two switch design.
For my datacenter I would need two 48 ports 10GBASE-T switches and two 48 port 10/25G fibber switches. So I was watching the Small Fabrics and Lower-Speed Interfaces part of Physical Fabric Design to make up my mind. There you talk about the possibility to do a leaf and spine with 4 switches and connect servers to the spine.
A picture is worth a thousand words, so here’s the diagram of what I had in mind:
Guide to NSX Security at VMworld 2021
The world is changing and as a result, the ability to operationalize network security at scale is more important than ever. Organizations need the ability to monitor and protect both East-West and North-South traffic at scale without adding operational complexity or impacting the user experience. How do organizations do all this in the face of reduced budgets, increasing network complexity, radical changes throughout IT architectures and an increase in volume and sophistication of cybersecurity threats?
We’ll show you at VMworld 2021 with sessions dedicated to helping you operationalize network security at scale in today’s modern world.

Why securing internet-facing applications is challenging in a Kubernetes environment
Internet-facing applications are some of the most targeted workloads by threat actors. Securing this type of application is a must in order to protect your network, but this task is more complex in Kubernetes than in traditional environments, and it poses some challenges. Not only are threats magnified in a Kubernetes environment, but internet-facing applications in Kubernetes are also more vulnerable than their counterparts in traditional environments. Let’s take a look at the reasons behind these challenges, and the steps you should take to protect your Kubernetes workloads.
Threats are magnified in a Kubernetes environment
One of the fundamental challenges in a Kubernetes environment is that there is no finite set of methods that exist in terms of how workloads can be attacked. This means there are a multitude of ways an internet-facing application could be compromised, and a multitude of ways that such an attack could propagate within the environment.
Kubernetes is designed in such a way that allows anything inside a cluster to communicate with anything else inside the cluster by default, essentially giving an attacker who manages to gain a foothold unlimited access and a large attack surface. Because of this design, any time you have Continue reading
Hedge 101: In Situ OAM
Understanding the flow of a packet is difficult in modern networks, particularly data center fabrics with their wide fanout and high ECMP counts. At the same time, solving this problem is becoming increasingly important as quality of experience becomes the dominant measure of the network. A number of vendor-specific solutions are being developed to solve this problem. In this episode of the Hedge, Frank Brockners and Shwetha Bhandari join Alvaro Retana and Russ White to discuss the in-situ OAM work currently in progress in the IPPM WG of the IETF.
