Large Scale Network Design LiveLesson

Alvaro and I finished recording a new LiveLesson back in December; it should be available for pre-purchase at the end of January. For those folks interested in network design, this is going to be a great video series. We originally started out with the idea of updating Optimal Routing Design, but the project quickly morphed into its “own thing,” which means this video series is actually more of a compliment to ORD, rather than a replacement. Some pieces will be more up-to-date than the book, but there are a number of things covered in the book that are not covered in the video.

Large Scale Network Design LiveLessons takes you through the concepts behind stable, scalable, elegant network design, including modularity, resilience, layering, and security principles. This livelesson will focus on traditional distributed link state, distance vector, and path vector routing protocols, as well as the basic principles of centralized control planes (such as OpenFlow). A special point will be made of sorting out the relationship between policy and reachability, and where they can best be managed in a large scale network.

IDG Contributor Network: SADA Systems grows its cloud consulting business

Cloud. Despite all the hype about it being super easy, being self service and having a low on-ramp, the reality is service providers often still need to help organizations with the move to the cloud.You can tell an area is getting widespread attention when the large consulting firms start pricking up there ears. And so it is with cloud computing, where we have seen over the past few years the large consulting firms (both the “big four” accounting firms and the more traditional IT consulting firms) building out cloud computing service offerings—either from within or via strategic acquisitions of service providers.+ Also on Network World: Cloud adoption soars, but integration challenges remain + A good example of this came in 2015 when Accenture acquired Cloud Sherpas, a Salesforce and Amazon Web Services (AWS) consulting partner that had grown rapidly over the preceding years via a number of acquisitions and mergers.To read this article in full or to leave a comment, please click here

Secdo automates alert investigation with preemptive incident response  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.   “We don’t receive enough alerts in our security operations center,” said no security analyst ever. The fact is, most SOC teams are overwhelmed with security alerts and they must prioritize which ones to investigate. Many alerts are simply ignored for lack of resources, yet quite often after a data breach it turns out there was an alert pointing at the breach early on. In the case of one prominent breach at a major retailer a few years ago, many sources report that a FireEye tool generated an alert confirming that malicious software showed up on a company system. Because so many of those particular alerts were false positives, it was ignored, which subsequently led to one of the largest and most costly retail data breaches in history.To read this article in full or to leave a comment, please click here

Worth Reading: Studying the IPv4 transfer market

The Internet community anticipated this almost two decades ago and standardized IPv6 as a long-term solution. IPv6 uptake is, however, still lagging. Hence, affected businesses have actively started seeking stop-gap measures to prolong the lifetime of IPv4 addresses. These measures include address space redistribution, deploying large scale NATs, and trading IPv4 blocks on the IPv4 transfer market. The emergence of this market has radically changed the nature of IPv4 addresses from a free resource to a commodity, which has raised many questions about market regulations. This blog post explores the evolution of the IPv4 transfer market. —APNIC

Attackers start wiping data from CouchDB and Hadoop databases

It was only a matter of time until ransomware groups that wiped data from thousands of MongoDB databases and Elasticsearch clusters started targeting other data storage technologies. Researchers are now observing similar destructive attacks hitting openly accessible Hadoop and CouchDB deployments.Security researchers Victor Gevers and Niall Merrigan, who monitored the MongoDB and Elasticsearch attacks so far, have also started keeping track of the new Hadoop and CouchDB victims. The two have put together spreadsheets on Google Docs where they document the different attack signatures and messages left behind after data gets wiped from databases.To read this article in full or to leave a comment, please click here

4 Critical Internet Questions The G20 Leaders Will Debate in 2017

More proof the cloud is winning big

One way to track the growth of cloud computing is to follow the investments in the infrastructure and equipment that make it run. That’s why IDC’s Worldwide Quarterly Cloud IT Infrastructure Tracker is so revealing.The cloud is growing faster According to the IDC report, total spending on IT infrastructure products—including server, enterprise storage and Ethernet switches—for use in cloud environments will grow a healthy 18 percent this year to top $44 billion. Meanwhile, IDC said, investment in old-school non-cloud architecture equipment will actually decline by more than 3 percent in 2017.To read this article in full or to leave a comment, please click here
