Helping To Build Cloudflare, Part 6: What does Cloudflare’s CTO do?

This is the final part of a six part series based on a talk I gave in Trento, Italy. To start from the beginning go here.

If you are still awake there’s really one final question that you might want to know the answer to: What does the CTO do? The reality is that it means different things in different companies. But I can tell you a little about what I do.

The longest temporary job

I didn’t join Cloudflare as CTO. My original job title was Programmer and for the first couple of years I did just that. I wrote a piece of technology called Railgun (a differential compression program used to speed up the connection between Cloudflare and origin web servers) and then I went on to write our WAF. After that I worked on our Go-based DNS server and other parts of the stack.

At some point Lee Holloway decided he didn’t want to manage Cloudflare’s growing staff and Michelle Zatlyn (one of Cloudflare’s founders) asked me if I would ‘temporarily’ manage engineering. This is now the longest temporary job I’ve ever had!

Initially a lot of what I did was manage the team and help interview Continue reading

Securing your SWIFT environment with VMware

The SWIFT Controls Framework was created to help customers figure out which controls are needed to better secure their SWIFT environment.  The SWIFT security controls framework is broken down into objectives, principles, and controls.   The three objectives are “Secure your environment, Know and Limit Access, and Detect and Respond”.

Customers interested in exploring VMware product alignment with the SWIFT framework should evaluate the end-to-end solution. This includes VMware products, as well as other technology that support a customer’s SWIFT platform. The following is a high-level alignment of some of the SWIFT framework controls and VMware products.

VMware Product Alignment with SWIFT Objectives

Restrict internet access & Protect Critical Systems from General IT Environment

As part of a SWIFT deployment, a secured and zoned off environment must be created. This zone contains the SWIFT infrastructure that is used for all SWIFT transaction.  Two SWIFT Principles that we will discuss are

• Protect Critical Systems from General IT Environment
• Detect Anomalous Activity to Systems or Transaction Records

These controls are required to be enforced on the SWIFT infrastructure.  SWIFT requires that all traffic from the general IT infrastructure to the SWIFT zone be as restricted as possible.   They also Continue reading

Cisco to MikroTik – Switching and VLANs

About the Cisco to MikroTik series

One of the most difficult configuration challenges for MikroTik equipment seems to be switching and VLANs in the CRS series. Admittedly, the revamp of VLAN configuration for MikroTik CRS switches in early 2018 made things a lot easier. But, sometimes there is still confusion on how to configure VLANs and IP addresses in VLANs with MikroTik RouterOS operating on a switch.

This will only cover VLAN configuration for CRS 3xx series switches in RouterOS as SwitchOS is not nearly as common in operational deployments.

CRS 1xx/2xx series use an older style of configuration and seem to be on the way out so I’m not 100% sure whether or not i’ll write a similar guide on that series.

If you’ve been in networking for a while, you probably started with learning the Cisco CLI. Therefore, it is helpful to compare the commands if you want to implement a network with a MikroTik and Cisco switches.

This is the fourth post in a series that creates a Rosetta stone between IOS and RouterOS. Here are some of the others:

History of Networking: ILNP with Saleem Bhatti

Using a single IP address to provide both identity and location information can create challenges and inefficiencies in network design. In this History of Networking episode, we sit down with Saleem Bhatti to talk about the history of ILNP and IP mobility to see how this tech aims to resolve this challenge.

IDG Contributor Network: The role of open source in networking

Technology is always evolving. However, in recent time, two significant changes have emerged in the world of networking. Firstly, the networking is moving to software that can run on commodity off-the-shelf hardware. Secondly, we are witnessing the introduction and use of many open source technologies, removing the barrier of entry for new product innovation and rapid market access.Networking is the last bastion within IT to adopt the open source. Consequently, this has badly hit the networking industry in terms of slow speed of innovation and high costs. Every other element of IT has seen radical technology and cost model changes over the past 10 years. However, IP networking has not changed much since the mid-’90s.To read this article in full, please click here

BrandPost: 3 Ways 802.11ax Makes Wi-Fi Better

Introduced in 1997, the IEEE 802.11 standard, more commonly known as Wi-Fi, has continually evolved to address the need of increased speeds in enterprise Wi-Fi networks. Of late, however, data rate and throughput have become table stakes in any high-density WLAN deployment.That's because there has been an explosion in the number of client devices per household. Offices and public spaces like malls, stadiums, and concert venues also boast of highly dense client environments. The demand has shifted from "high speed Wi-Fi" to "fast and efficient Wi-Fi in extremely dense environments."Enter 11ax. With the introduction of 802.11ax (also known as Wi-Fi 6), the wireless industry is now delivering bandwidth and efficiency several times that of the legacy 802.11b.To read this article in full, please click here

Cloudflare Support for Azure Customers

Cloudflare seeks to help its end customers use whichever public and private clouds best suit their needs.  Towards that goal, we have been working to make sure our solutions work well with various public cloud providers including Microsoft’s Azure platform.

If you are an Azure customer, or thinking about becoming one, here are three ways we have made Cloudflare’s performance and security services work well with Azure.

1) The development of an Azure application for Cloudflare Argo Tunnel.

We are proud to announce an application for Cloudflare Argo Tunnel within the Azure marketplace. As a quick reminder, Argo Tunnel establishes an encrypted connection between the origin and the Cloudflare edge. The small tunnel daemon establishes outbound connections to the two nearest Cloudflare PoPs,  and the origin is only accessible via the tunnel between Cloudflare and origin.

Because these are outbound connections, there is likely no need to modify firewall rules, configure DNS records, etc.  You can even go so far as to block all IPs on the origin and allow traffic only to flow through the tunnel. You can learn more here. The only prerequisite for using Argo Tunnel is to have Argo enabled on your Cloudflare zone. You can Continue reading
