One of my readers sent me this question:
How can I learn more about reading REST API information from network devices and storing the data into tables?
Long story short: it’s like learning how to drive (well) - you have to master multiple seemingly-unrelated tasks to get the job done.

As I’ve been busy with Cisco Live, I’m only now starting to write these posts. I’m expecting to write a couple of them rather than writing one LONG one.
As a member of the CCIE Advisory Council, I’ve been in the loop for a while and I truly believe these changes are for the better. We’ve tried to do what is best for people that are certified or looking to get certified. There will certainly be corner cases or questions that need answers, but we have done our best to leave noone behind.
This first post will look at what is changing at a high level and then we can dive deeper into the different certifications in the coming posts.
DevNet certifications – There has been some training on automation and even some exams, but no real certifications. This is all changing now. There will be corresponding DevNet certifications for CCNA, CCNP and in the future, CCIE. This offers more career paths within the Cisco world. I will cover the DevNet certifications in a future post.

Way back in the day, when telephone lines were first being installed, running the physical infrastructure was quite expensive. The first attempt to maximize the infrastructure was the party line. In modern terms, the party line is just an Ethernet segment for the telephone. Anyone can pick up and talk to anyone else who happens to be listening. In order to schedule things, a user could contact an operator, who could then “ring” the appropriate phone to signal another user to “pick up.” CSMA/CA, in essence, with a human scheduler.
This proved to be somewhat unacceptable to everyone other than various intelligence agencies, so the operator’s position was “upgraded.” A line was run to each structure (house or business) and terminated at a switchboard. Each line terminated into a jack, and patch cables were supplied to the operator, who could then connect two telephone lines by inserting a jumper cable between the appropriate jacks.
An important concept: this kind of operator driven system is nonblocking. If Joe calls Susan, then Joe and Susan cannot also talk to someone other than one another for the duration of their call. If Joe’s line is tied up, when someone tries to Continue reading
The use of Internet of Things devices has substantially increased in recent years and the trends indicate that the number will continue to grow significantly. In this environment of rapid technological adoption, the inclusive and collaborative approach is essential to face the challenges and take advantage of the opportunities that arise.
Specifically, to overcome the privacy and security challenges associated with the growing number of Internet of Things (IoT) devices and systems, the Internet Society signed an agreement with the Agency of Electronic Government and the Information and Knowledge Society of Uruguay (Agesic). The agreement will encourage us to strengthen our collaborative ties to develop a multistakeholder process that will seek to issue recommendations on IoT security in the country.
The recommendations issued will be useful to guide the processes of development of national and regulatory policies in Uruguay. In addition, the agreement focuses on two broad areas: the exchange of information and the development of training materials on consumer protection and network resilience.
This is undoubtedly great news for the region, since Uruguay joins a group of countries that have opted for the multistakeholder processes to strengthen the security of IoT devices. The most recent example is Canada, whose Continue reading

Big targets: Internet-connected security cameras make up nearly half of all the Internet of Things devices compromised by hackers, ZDNet reports. Smart hubs and network-attached storage devices are next on the hit list. The average U.S. household contains 17 Internet-connected devices, while the average European household has 14.
New rules for the IoT? A U.S. House of Representatives committee has approved an IoT security bill that would create security standards that vendors would have to apply before government agencies could buy IoT devices from them, Nextgov says. The legislation aims to leverage the government’s substantial purchasing power to drive security in the IoT market.
Cleaning house: The Chinese government has blocked several foreign media sites in the name of cleaning up the Internet, Reuters reports. China’s campaign will punish and expose websites for “illegal and criminal actions” and for failing to “fulfil their obligation” to take safety measures or prevent the theft of personal information, the government says.

To kick-off Crypto Week 2019, we are really excited to announce a new solution to a long-standing problem in cryptography. To get a better understanding of the technical side behind this problem, please refer to the next post for a deeper dive.
Everything from cryptography to big money lottery to quantum mechanics requires some form of randomness. But what exactly does it mean for a number to be randomly generated and where does the randomness come from?
Generating randomness dates back three thousand years, when the ancients rolled “the bones” to determine their fate. Think of lotteries-- seems simple, right? Everyone buys their tickets, chooses six numbers, and waits for an official to draw them randomly from a basket. Sounds like a foolproof solution. And then in 1980, the host of the Pennsylvania lottery drawing was busted for using weighted balls to choose the winning number. This lesson, along with the need of other complex systems for generating random numbers spurred the creation of random number generators.
Just like a lottery game selects random numbers unpredictably, a random number generator is a device or software responsible for generating sequences of numbers in an unpredictable manner. As the need for Continue reading
