In this article I cover CLI device modes and privilege levels. I also cover the basics of navigating between modes and getting more comfortable with some CLI commands.

How do you know the code your web browser downloads when visiting a website is the code the website intended you to run? In contrast to a mobile app downloaded from a trusted app store, the web doesn’t provide the same degree of assurance that the code hasn’t been tampered with. Today, we’re excited to be partnering with WhatsApp to provide a system that assures users that the code run when they visit WhatsApp on the web is the code that WhatsApp intended.
With WhatsApp usage in the browser growing, and the increasing number of at-risk users — including journalists, activists, and human rights defenders — WhatsApp wanted to take steps to provide assurances to browser-based users. They approached us to help dramatically raise the bar for third-parties looking to compromise or otherwise tamper with the code responsible for end-to-end encryption of messages between WhatsApp users.
So how will this work? Cloudflare holds a hash of the code that WhatsApp users should be running. When users run WhatsApp in their browser, the WhatsApp Code Verify extension compares a hash of that code that is executing in their browser with the hash that Cloudflare has — enabling them to easily see Continue reading
The internet has become part of society now and this means that governments will want to put controls on it. Are our standards bodies fit for purpose ?

Social media is one of the most used sites all over the world used by most mobile users counting to hundreds of millions of users. It provides different services to its users. It can be used as a fun site to upload images and videos, as a means of communication, as a way to meet different people of different beliefs and cultures all over the world, to learn and explore new and different things, and also as a business place. You reading this article also includes you among the social media users and you’ll know that there is a lot to benefit from using these sites. Let’s consider some of the most popular social media sites and what you should know about them.
LISP started as yet-another ocean-boiling project focused initially on solving the “we use locators as identifiers” mess (not quite), and providing scalable IPv6 connectivity over IPv4-only transport networks by adding another layer of indirection and thus yet again proving RFC 1925 rule 6a. At least those are the diagrams I remember from the early “look at this wonderful tool” presentations explaining for example how Facebook is using LISP to deploy IPv6 (more details in this presentation).
Somehow that use case failed to gain traction and so the pivots1 started explaining how one can use LISP to solve IP mobility or IP multihoming or live VM migration, or to implement IP version of conversational learning in Cisco SD-Access. After a few years of those pivots, I started dismissing LISP with a short “cache-based forwarding never worked well” counterargument.

VMware-based workload environments are the norm in private clouds for enterprise-class customers. 100%[1] of Fortune 500 companies deploy vSphere/ESXi. Further, ~99% of Fortune 1000 and ~98%[2] of Forbes Global 2000 companies deploy vSphere/ESXi. VMware’s deep presence in enterprise private clouds has made NSX Firewall the preferred micro-segmentation solution for these enterprises.
Below, we expand on how the NSX Firewall has developed its prominent position in enterprise private clouds.
Virtualized x86 workloads on hypervisors represent ~80%[3] of all enterprise workloads. VMware’s hypervisor-based micro-segmentation solution – NSX Firewall – is the preferred agentless solution for such workloads because of the solution’s tight integration with the rest of the VMware eco-system.
~15% of workloads at enterprises are x86-based (Windows, Linux) but not virtualized. The NSX Firewall handles these workloads with NSX agents.
~5% of workloads at enterprises are non-x86-based. VMware provides an (agentless) layer 2-7 gateway firewall that supports micro-segmentation for these workloads. Note that the gateway firewall eliminates the need for integration with physical switches, routers, and load-balancers.
Between these mechanisms, 100% of all workloads in the private cloud are protected. In practice, given VMware’s penetration of enterprises, VMware’s agentless solutions apply to the vast Continue reading
Can computation be drawn into the network, rather than always being pushed to the edge of the network? Taking content distribution networks as a starting point, the COIN research group is looking at ways to make networks more content and computationally aware, bringing compute into the network itself. Join Alvaro Retana, Marie-Jose Montpetit, and Russ White, as we discuss the ongoing research around computing in the network.
