With the complexity of our industry, two things should be obviously necessary. These two things are Network Design and Validation Testing. Design requires identifying the requirements of the business and of dependent systems. This could include things like minimum bandwidth, maximum jitter, convergence time, recovery time, minimal redundancy, etc. It is also important to understand that more rigorous requirements often contribute to cost and operational complexity. Operational complexity creates additional challenges that often erode the very parameters that have been identified as requirements. When this is found true, there are some conversations that need to be had about what is and is not achievable, given the operational and capital budgets–as well as the realistic capabilities of the staff managing the environment.
Validation is also critically important. I posted an article a few weeks ago that illustrated an interesting failure with CAPWAP. Avoiding issues like this require us to first design our network then validate the behavior against the design. Allow me to make a bold statement–If you haven’t designed and validated your network, you DON’T know how it works. Without validation–How do you know that your convergence is subsecond? How do you know that your backup routes work with applications? Continue reading

In this post I’ll briefly describe the problem in the gRPC domain and a solution based on gRPC-Web, Envoy proxy and Istio to neatly solve it.
gRPC is a universal, high-performance, open-source RPC framework based on HTTP/2. Essentially, it lets you easily define a service using Protocol Buffers (Protobufs), works across multiple languages and platforms, and is simple to set up and scale. All this leads to better network performance and flexible API management.
gRPC-Web addresses a shortcoming in the core gRPC framework. As developers look to benefit from the advantages it confers beyond backend microservices—the fact that it doesn’t work so well with web applications running on browsers. Although most browsers support HTTP/2 and gRPC is based on HTTP/2, gRPC has its own protocols that web applications must understand in order to work properly with it. Web applications do not have this capability because browsers don’t support gRPC out of the box.
One way to get around this problem is to use the gRPC-Web plugin and run a proxy like Envoy along with it. Envoy serves as the default proxy for Istio, and on configuring its gRPC-Web filter, it can transcode HTTP requests/responses Continue reading
In 2018 the Internet Society launched the Trust by Design campaign, to make sure that security and privacy features are built into Internet of Things (IoT) products. We focused our activities on consumer IoT, a segment particularly vulnerable, despite having the biggest share in the IoT market. We believe trust should come as standard, and so we’ve been working with manufacturers and suppliers to make sure privacy and security are included in the initial design phase all the way through the product lifecycle, as outlined in the OTA IoT Trust Framework. Our work does not stop there, as this goal can only be achieved when consumers drive demand for security and privacy capabilities as a market differentiator and policymakers create a policy environment that strengthens trust and enables innovation.
Consumer IoT devices and services without adequate security pose a wide range of risks, from directly threatening the security, privacy, and safety of their owners to the devices themselves turning into botnets that can initiate DDoS attacks against the Internet. As more and more connected devices with weak security are rushed to the market due to competition and cost concerns, missing trust is deeply rooted in economics. To better understand the Continue reading

What’s my password again? Microsoft has changed its baseline security configuration, which had suggested passwords be changed every 60 days, Ars Technica reports. Requiring users to change passwords so often can be counterproductive by encouraging them to pick easy-to-remember passwords, the article says.
Big money: Facebook has set aside $3 billion to pay a potential fine to the U.S. Federal Trade Commission over its handling of users’ personal data and various data breaches, CNet reports. Some critics say the expected fine, which could reach $5 billion, is a slap on the wrist for a company that clears tens of billions a year in profits, Recode suggests.
Blocking speech: Terrorist attacks in Sri Lanka that killed more than 350 people on April 21 have prompted the government there to block social media in an effort to prevent the spread of fake news, CNN reports. While some groups praised the decision others said that restricting free speech isn’t productive, Wired.com says.
Censorship on the rise: Meanwhile, it’s becoming increasingly common for governments to block Facebook and other social media for a variety of reasons. This social media blocking could lead to wider censorship efforts, The Verge suggests.
