Batten down the DNS hatches as attackers strike Feds

If enterprise IT folks haven’t taken a look at their DNS ecosystem recently now may be a good time. This week the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) told all federal agencies to bolt down their Domain Name System in the face of a  series of global hacking campaigns.

HPE predicts storage-class memory will replace NAND flash

Storage-class memory (SCM), RAM that has the ability to retain its contents like NAND flash memory but the speed of DRAM, will eventually supplant flash as the high-speed storage medium of choice.That’s the prediction of Ivan Iannaccone, vice president and general manager of HPE’s 3PAR storage unit. But he adds that it will take some time.“It’s not going to happen overnight; it’s just a matter of time for it to become economically viable, but it will eventually take over. Maybe in 10 years,” he told me.[ Read also: Why disk beat tape in the backup wars | Get daily network and data center insights: Sign up for Network World newsletters ] On a per-byte basis, SCM is around four times more expensive than flash. Currently only two vendors make it: Intel and Samsung. Intel sells it under the Optane brand and targets it at enterprises, and Intel’s Optane HPE uses it in its storage arrays.To read this article in full, please click here

Cisco patches serious SD-WAN software security holes

Cisco has patched security vulnerabilities in four packages of SD-WAN Solution software that address buffer overflow, arbitrary file override and privilege access weaknesses that could have led to denial of service attacks or access problems.The first patch, called “Critical” by Cisco, fixes a vulnerability in the vContainer of the Cisco SD-WAN Solution that could let an authenticated, remote attacker cause a denial of service (DoS) and execute arbitrary code as the root user, the company wrote in a security advisory. To read this article in full, please click here

Introducing the Workers Cache API: Giving you control over how your content is cached

Introducing the Workers Cache API: Giving you control over how your content is cached

At Cloudflare, we aim to make the Internet faster and safer for everyone. One way we do this is through caching: we keep a copy of our customer content in our 165 data centers around the world. This brings content  closer to users and reduces traffic back to origin servers.

Today, we’re excited to announce a huge change in our how cache works. Cloudflare Workers now integrates the Cache API, giving you programmatic control over our caches around the world.

Why the Cache API?

Figuring out what to cache and how can get complicated. Consider an e-commerce site with a shopping cart, a Content Management System (CMS) with many templates and hundreds of articles, or a GraphQL API. Each contains a mix of elements that are dynamic for some users, but might stay unchanged for the vast majority of requests.

Over the last 8 years, we’ve added more features to give our customers flexibility and control over what goes in the cache. However, we’ve learned that we need to offer more than just adding settings in our dashboard. Our customers have told us clearly that they want to be able to express their ideas in code, to build Continue reading

Moving Forward to an Internet That’s Interplanetary in Scope and Function

The IPNSIG (InterPlanetary Networking Special Interest Group) has been a Chapter of the Internet Society since February 2014. We are pleased to announce that we recently created a blog dedicated to everyone interested in IPN and DTN, and computer networking in general. It is a first step in providing nonspecialists with easy-to-understand explanations of what IPN is and how it works. Each week, we will post news about the exciting world of IPN, summaries of academic research, or links to IPN in the mainstream media. We’ll also be announcing upcoming IPNSIG events and activities.

Our mission
We aim to realize a functional and scalable system of interplanetary data communications before the year 2020. We will accomplish this objective by engaging the public’s interest in funding and executing the research and technology development necessary to make InterPlanetary Networking (IPN) a reality. We will educate them about the critical need for a reliable, scalable space data network to enable cost-effective exploration and eventual commercial use of the inner solar system. We will excite them about the potential role these same network systems technologies can play in solving communication problems here on earth.

What is IPN?
It is a solution to the constrained Continue reading
