IoT startups fill security gaps

As the volume of IoT devices connecting to enterprise networks continues to climb, the number of security threats has been increasing in lockstep. Cybersecurity threats, alongside supply chain issues, chip shortages and geopolitical instability, are a major reason that IoT growth has been slower than many analysts had predicted.Even so, the scale of the IoT security problem is great enough that 52 IoT startups raised a total of $840 million in the latest quarter, and even cautious analysts believe the IoT market will grow steadily in the coming years. In fact, research firm IDC predicts that the IoT market will expand to 55.7 billion connected IoT devices by 2025, with those devices generating 80B zettabytes (ZB) of data.To read this article in full, please click here

Dataplane MAC Learning with EVPN

Johannes Resch submitted the following comment to the Is Dynamic MAC Learning Better Than EVPN? blog post:

I’ve also recently noticed some vendors claiming that dataplane MAC learning is so much better because it reduces the number of BGP updates in large scale SP EVPN deployments. Apparently, some of them are working on IETF drafts to bring dataplane MAC learning “back” to EVPN. Not sure if this is really a relevant point - we know that BGP scales nicely, and its relatively easy to deploy virtualized RR with sufficient VPU resources.

While he’s absolutely correct that BGP scales nicely, the questions to ask is “what is the optimal way to deliver a Carrier Ethernet service?”

On the ‘net: Network Models at Packet Pushers

I’ve just started a new series on network models over at Packet Pushers. The first two installments are here:

I learned the Open Systems Interconnect (OSI) model way back in the mid-1980s, as a part of my basic networking education. Ever since then, I’ve used the OSI model in my day-to-day work as a network engineer.

First, models are not sacrosanct. A model is just a tool. If the model you are using is not working for you, feel free to modify it.

On the ‘Net: The IETF at Packet Pushers

I’ve been writing a series about working within the IETF to publish a new standard over at Packet Pushers. The most recent installments are:

There are other seemingly mystical concepts in the IETF process as well—for instance, what is a “document stream,” and what is a document’s “status?”

You’re almost ready to submit a shiny new document to the IETF for consideration, right? Not quite yet—we still need to deal with mandatory sections and language.

Schedule 0923

Here’s a preview of what I’m working on for those who are interested:

  • September 2023: (this Friday) How Routers Really Work, a three-hour live webinar at Safari Books Online through Pearson
  • October 2023:
    • How the Internet Really Works a four-hour live webinar at Safari Books Online through Pearson; this is newly formatted and reorganized version of the two sessions I used to do
    • I’m speaking at a small theological conference on AI and ethics in Cary, NC
  • November 2023:
    • The new CCST book should be released
    • I have recorded a network basics video series that should be released in late 2023 or early 2024
  • January 2024:
    • What Coders Need to Know about Networks, a new course, co-authored with an engineer from Akamai; a three-hour live webinar at Safari Books Online through Pearson
    • I’ll be teaching a course in network engineering at the University of Colorado for the spring semester
  • February 2024: A new three-hour live webinar on infrastructure interviewing skills at Safari Books Online through Pearson
  • March 2024: BGP Policy, a three-hour live webinar on Safari Books Online through Pearson
  • April 2024: Troubleshooting, a reformatted and rebuilt three-hour live webinar at Safari Books Online through Pearson

IBM X-Force: Use of compromised credentials darkens cloud security picture

As connectivity to cloud-based resources grows, cybercriminals are using valid, compromised credentials to access enterprise resources at an alarming rate.That's one of the chief findings of the IBM X-Force Cloud Threat Landscape Report, which also found a 200% increase (about 3,900 vulnerabilities) in cloud-oriented Common Vulnerabilities and Exposures (CVE) in the last year.“Over 35% of cloud security incidents occurred from attackers’ use of valid, compromised credentials,” wrote Chris Caridi, strategic cyber threat analyst with IBM X-Force, in a blog about the report. “Making up nearly 90% of assets for sale on dark web marketplaces, credentials’ popularity among cybercriminals is apparent, averaging $10 per listing – or the equivalent of a dozen doughnuts.”To read this article in full, please click here
