How BCG Gamma is Transforming Analytics with Docker

Changing the culture and service offerings of a big consulting firm isn’t easy, but BCG has been on that path for the past five years. BCG has evolved from traditional consulting services into a digital transformation powerhouse with six divisions that deliver strategic and technical services to clients.

One of those divisions, BCG Gamma, is a global team of world-class data scientists who build data analytics, machine learning, and artificial intelligence solutions for the firm’s clients. But building and shipping analytics, ML and AI applications to clients is challenging. Andrea Gallego, CTO of the division, is charged with creating an infrastructure that can support delivering high-quality ML and AI models at scale.

The Challenge: Shipping ML and AI Software to Clients at Scale

The big question on her mind was how BCG Gamma could not only build models, but deliver them to clients at the edge with real-time orchestration, monitoring and updates. GDPR and other regulations also meant she had to do this while ensuring integrity, consistency and lineage across data models.

Andrea and her team launched the BCG GammaX initiative, a core team of 30 engineers specializing in analytics software engineering, data engineering, UX design, distributed systems, and Continue reading

Episode 31 – Analytics and Security

Security is facing a crisis of well trained engineers. As a result, operators are relying more heavily on analytics to provide security intelligence. In this show, Eric Osterweil joins Network Collective to discuss the use of analytics in security, and the role analytics can play to augment engineering talent.

Going Proactive on Security: Driving Encryption Adoption Intelligently

Going Proactive on Security: Driving Encryption Adoption Intelligently

It's no secret that Cloudflare operates at a huge scale. Cloudflare provides security and performance to over 9 million websites all around the world, from small businesses and WordPress blogs to Fortune 500 companies. That means one in every 10 web requests goes through our network.

However, hidden behind the scenes, we offer support in using our platform to all our customers - whether they're on our free plan or on our Enterprise offering. This blog post dives into some of the technology that helps make this possible and how we're using it to drive encryption and build a better web.

Why Now?

Recently web browser vendors have been working on extending encryption on the internet. Traditionally they would use positive indicators to mark encrypted traffic as secure; when traffic was served securely over HTTPS, a green padlock would indicate in your browser that this was the case. In moving to standardise encryption online, Google Chrome have been leading the charge in marking insecure page loads as "Not Secure". Today, this UI change has been pushed out to all Google Chrome users globally for all websites: any website loaded over HTTP will be marked as insecure.

Cloudflare Access: Now teams of any size can turn off their VPN

Cloudflare Access: Now teams of any size can turn off their VPN

Cloudflare Access: Now teams of any size can turn off their VPN

Using a VPN is painful. Logging-in interrupts your workflow. You have to remember a separate set of credentials, which your administrator has to manage. The VPN slows you down when you're away from the office. Beyond just inconvenience, a VPN can pose a real security risk. A single infected device or malicious user can compromise your network once inside the perimeter.

In response, large enterprises have deployed expensive zero trust solutions. The name sounds counterintuitive - don’t we want to add trust to our network security? Zero trust refers to the default state of these tools. They trust no one; each request has to prove that itself. This architecture, most notably demonstrated at Google with Beyondcorp, has allowed teams to start to migrate to a more secure method of access control.

However, users of zero trust tools still suffer from the same latency problems they endured with old-school VPNs. Even worse, the price tag puts these tools out of reach for most teams.

Here at Cloudflare, we shared those same frustrations with VPNs. After evaluating our options, we realized we could build a better zero trust solution by leveraging some of the unique capabilities we have here at Cloudflare:

Today, Chrome Takes Another Step Forward in Addressing the Design Flaw That is an Unencrypted Web

Today, Chrome Takes Another Step Forward in Addressing the Design Flaw That is an Unencrypted Web

The following is a guest post by Troy Hunt, awarded Security expert, blogger, and Pluralsight author. He’s also the creator of the popular Have I been pwned?, the free aggregation service that helps the owners of over 5 billion accounts impacted by data breaches.

Today, Chrome Takes Another Step Forward in Addressing the Design Flaw That is an Unencrypted Web

I still clearly remember my first foray onto the internet as a university student back in the mid 90's. It was a simpler online time back then, of course; we weren't doing our personal banking or our tax returns or handling our medical records so the whole premise of encrypting the transport layer wasn't exactly a high priority. In time, those services came along and so did the need to have some assurances about the confidentiality of the material we were sending around over other people's networks and computers. SSL as it was at the time was costly, but hey, banks and the like could absorb that given the nature of their businesses. However, at the time, there were all sorts of problems with the premise of serving traffic securely ranging from the cost of certs to the effort involved in obtaining and configuring them through to the performance hit on the Continue reading

Research: Even Password Complexity is a Tradeoff

Stronger passwords are always better—at least this is the working theory of most folks in information technology, security or otherwise. Such blanket rules should raise your suspicions, however; the rule11 maxim if you haven’t found the tradeoff, you haven’t looked hard enough should apply to passwords, too.

Dinei Florêncio, Cormac Herley, and Paul C. Van Oorschot. 2016. Pushing on string: the ‘don’t care’ region of password strength. Commun. ACM 59, 11 (October 2016), 66-74. DOI: https://doi.org/10.1145/2934663

Begin with this simple assertion: complex passwords are primarily a guard against password guessing attacks. Further, while the loss of a single account can be tragic for the individual user (and in some systems, the loss of a single password can have massive consequences!), for the system operator, it is the overall health of the system that matters. There is, in any system, a point at which enough accounts have been compromised that the system itself can no longer secure any information. This not only means the system can no longer hide information, it also means transactions within the system can no longer be trusted.

The number of compromised accounts varies based on the kind of system in view; effectively breaching Continue reading

Securing U.S. Democracy: Athenian Project Update

Securing U.S. Democracy: Athenian Project Update

Securing U.S. Democracy: Athenian Project Update
Last December, Cloudflare announced the Athenian Project to help protect U.S. state and local election websites from cyber attack.

Since then, the need to protect our electoral systems has become increasingly urgent. As described by Director of National Intelligence Dan Coats, the “digital infrastructure that serves this country is literally under attack.” Just last week, we learned new details about how state election systems were targeted for cyberattack during the 2016 election. The U.S. government’s indictment of twelve Russian military intelligence officers describes the scanning of state election-related websites for vulnerabilities and theft of personal information related to approximately 500,000 voters.

This direct attack on the U.S. election systems using common Internet vulnerabilities reinforces the need to ensure democratic institutions are protected from attack in the future. The Athenian Project is Cloudflare’s attempt to do our part to secure our democracy.

Engaging with Elections Officials

Since announcing the Athenian Project, we’ve talked to state, county, and municipal officials around the country about protecting their election and voter registration websites. Today, we’re proud to report that we have Athenian Project participants in 19 states, and are in talks with many more. We have also strategized with civil Continue reading
