How Did We End with 1500-byte MTU?
A subscriber sent me this intriguing question:
Is it not theoretically possible for Ethernet frames to be 64k long if ASIC vendors simply bothered or decided to design/make chipsets that supported it? How did we end up in the 1.5k neighborhood? In whose best interest did this happen?
Remember that Ethernet started as a shared-cable 10 Mbps technology. Transmitting a 64k frame on that technology would take approximately 50 msec (or as long as getting from East Coast to West Coast). Also, Ethernet had no tight media access control like Token Ring, so it would be possible for a single host to transmit multiple frames without anyone else getting airtime, resulting in unacceptable delays.

“I was told to buy a software or lose my computer. I ignored it”: a study of ransomware Simoiu et al., SOUPS 2019
This is a very easy to digest paper shedding light on the prevalence of ransomware and the characteristics of those most likely to be vulnerable to it. The data comes from a survey of 1,180 US adults conducted by YouGov, an online global market research firm. YouGov works hard to ensure respondent participation representative of (in this case) the general population in the U.S., but the normal caveats apply.
We define ransomware as the class of malware that attempts to defraud users by restricting access to the user’s computer or data, typically by locking the computer or encrypting data. There are thousands of different ransomware strains in existence today, varying in design and sophistication.
The survey takes just under 10 minutes to complete, and goes to some lengths to ensure that self-reporting victims really were victims of ransomware (and not some other computer problem).
For respondents that indicated they had suffered from a ransomware attack, data was collected on month and year, the name of the ransomware variant, the ransom demanded, the payment method, Continue reading

Overcoming the Barriers to Micro-segmentation
It should come as no surprise how much emphasis organizations place on security today. Threats are becoming more and more sophisticated and the number of threats grow to uncontrollable rates every day.
One of the biggest downsides is that the rising cost of data breaches in 2019 alone, a global average of $3.92 million as reported by the Ponemon Institute and IBM Security July 2019 report, is enough to cause organizations to rethink or increase emphasis on their security strategies and how they can help secure their most important assets by improving the cyber hygiene in their organizations.
What is Cyber Hygiene?
Cyber hygiene refers to what an organization can do to improve their security postures around physical hardware, software, and applications. If you’ve seen Pat Gelsinger’s keynote from 2017, he goes into the 5 pillars of good cyber hygiene and what organizations can do to improve basic and fundamental security for their business.
Over the last several years, VMware has been focusing on helping organizations move to Software-Defined Data Centers (SDDC) to improve their agility and meet the speed of business. As more organizations adopted the SDDC model, VMware found itself in a unique position Continue reading
