BrandPost: Overcoming Digital Transformation Challenges in Financial Services with SD-WAN

By: Gabriel Gomane, Sr Product Marketing Manager, Aruba, a Hewlett Packard Enterprise company.Whether for customers or employees, the digital transformation occurring at financial institutions has only accelerated in recent years. With that digital transformation, financial services organizations face an increasing array of networking and security challenges. These challenges include: digitization and cloud migration; the increasing percent of the workforce working from home; maintaining a modern and resilient network infrastructure; and last but certainly not least – cybersecurity risks and regulatory compliance.In response, SD-WAN has emerged as a key enabler to tackle and overcome these challenges while accelerating business growth. To illustrate how, below are five SD-WAN use cases from the financial services industry.To read this article in full, please click here

Cato adds fine-grained CASB controls to SASE platform

SASE vendor Cato Networks is adding fine-grained cloud access security broker (CASB) controls to its platforms.When employees working from home or branch locations log into SaaS services such as Office 365 or Dropbox or Salesforce, a CASB gateway can track the applications employees access, where they log in from, and sometimes even what they do when using those applications.Previously, Cato only offered limited CASB controls, enabling companies to allow or prohibit the use of particular SaaS tools, says Dave Greenfield, Cato's director of technology evangelism. Now, individual behaviors can be controlled. For example, users might be allowed to download documents from certain cloud file-sharing providers but can only upload documents to a company's preferred platform.To read this article in full, please click here

Gartner: Worldwide IT spending to reach $4.5T in 2022

Research firm Gartner forecasts IT spending will reach nearly $4.5 trillion worldwide this year, with enterprise software, IT services, and data center systems leading the way. The projected $4.45 trillion in spending this year represents an increase of 5.1% compared with 2021.The largest growth segment is enterprise software, which is projected to grow 11% to $672 billion. However, Gartner includes the cloud market in the enterprise software market, and that's where the growth is.

Where have all the global network aggregators gone?

One of the key selling points of SD-WAN is the ability to use a variety of network transport options. Enterprises can select MPLS, dedicated Internet access, business broadband, or wireless broadband, for example – whatever makes the most sense, technically and economically, for each site that needs connectivity. Cultivating a mix of suppliers can allow enterprises to significantly reduce transport costs as well as improve the flexibility of their networks.The growth in SD-WAN deployments over the last four or five years created a sweet spot for Internet transport aggregators, which, frankly, had struggled to break into the enterprise market when it was dominated by traditional MPLS providers.To read this article in full, please click here

Introducing our exciting new ambassador program: Calico Big Cats

The Project Calico community is one of the most collaborative and supportive communities in the open-source space. Our community has shown great engagement through the years, which has helped us maintain and grow the project.

Thanks to our 200+ contributors from all over the world, Calico Open Source (the solution born out of the project) is powering 1.5M+ nodes daily across 166 countries. Our engineering team is committed to maintaining Calico Open Source as the leading standard for container and Kubernetes networking and security!

Given our community’s passion for Project Calico, we wanted to give its members a chance to inspire others by telling their stories. To this end, we are very excited to announce our new Calico Big Cats ambassador program!

What is Calico Big Cats?

Calico Big Cats is an ambassador program that provides a platform for our community to talk about their experiences with Calico. The goal is to help community members connect, inspire, and share common challenges and ways to overcome these challenges using Calico and other tools.

Why join Calico Big Cats?

If you have experience with Project Calico, recognize its value in the open-source networking and security domain, and are passionate about sharing Continue reading

SSH over bluetooth – cleanly

In my previous two posts I set up a login prompt on a bluetooth serial port and then switched to running SSH on it.

I explicitly did not set up an IP network over bluetooth as I want to minimize the number of configurations (e.g. IP address) and increase the chance of it working when needed.

E.g. firewall misconfiguration or Linux’s various “clever” network managers that tend to wipe out network interface configs would have more of a shared fate with the primary access method (SSH over normal network).

This post is about how to accomplish this more properly.

The problems now being solved are:

  • It wasn’t entirely reliable. The rfcomm tool is pretty buggy.

  • There was no authentication of the Bluetooth channel. Not as much a problem when doing SSH, but if there are passwords then there could be a man-in-the-middle attack.

  • The server side had to remain discoverable forever. So anyone who scans for nearby bluetooth devices would see your servers, and would be able to connect, possibly brute forcing passwords. Not as much of a problem if running SSH with password authentication turned off, but why broadcast the name of a server if you don’t Continue reading

No, a researcher didn’t find Olympics app spying on you

For the Beijing 2022 Winter Olympics, the Chinese government requires everyone to download an app onto their phone. It has many security/privacy concerns, as CitizenLab documents. However, another researcher goes further, claiming his analysis proves the app is recording all audio all the time. His analysis is fraudulent. He shows a lot of technical content that looks plausible, but nowhere does he show anything that substantiates his claims.

Average techies may not be able to see this. It all looks technical. Therefore, I thought I'd describe one example of the problems with this data -- something the average techie can recognize.

His "evidence" consists screenshots from reverse-engineering tools, with red arrows pointing to the suspicious bits. An example of one of these screenshots is this on:


This screenshot is that of a reverse-engineering tool (Hopper, I think) that takes code and "disassembles" it. When you dump something into a reverse-engineering tool, it'll make a few assumptions about what it sees. These assumptions are usually wrong. There's a process where the human user looks at the analyzed output, does a "sniff-test" on whether it looks reasonable, and works with the tool until it gets the assumptions correct.

That's the red flag Continue reading
