NETWORKING

This blog is co-authored by Mohammad Iqbal and is part four of a four-part series about DevSecOps. The trend towards accelerated application development, and regular updates to an architecture through an agile methodology, reduces the efficacy and effectiveness of point-in-time threat modeling. This recognition led us to explore and strategize ways to continuously, and dynamically, threat model an application architecture during runtime. Today, thanks to a robust DevOps environment, developers can deploy a complex architecture…

In the IT world, specifically in networking, there aren’t many aspects that are as much of an enigma as subnetting—the act of creating subnetworks. Subnets are logical divisions of an existing network that are defined by both class of IP address and the subnet mask. Often, consultants provide network design services to budding businesses to help establish a network that fits their needs at the time. But as the business grows or its needs change…

For 20 years, Cisco and the Cisco Foundation have supported nonprofits that are developing technology-based solutions to help underserved and vulnerable communities. During that time, I have had the privilege to see those innovative solutions give people access to critical needs like food, clean water, and shelter, as well as create more opportunities for people to obtain an education, build skills, or run a business. Partnerships and investments in both nonprofit and for-profit solutions are…

Communications giant Verizon last week launched 5G for Business Internet in 20 new markets, targeting SMBs and enterprises alike. The fixed-wireless plans provide download speeds of 100Mbps ($69/month), 200Mbps ($99/month), and 400Mbps ($199/month) with no data limits. Upload speeds are slower. Verizon is also offering a 10-year price lock for new customers with no long-term contract required. “As 5G Business Internet scales into new cities, businesses of all sizes can gain access to the superfast…

There are quite a few tools that can help test your connectivity on the Linux command line. In this post, we’ll look at a series of commands that can help estimate your connection speed, test whether you can reach other systems, analyze connection delays, and determine whether particular services are available. ping The ping command is the simplest and most often used command for doing basic connectivity testing. It sends out packets called echo requests…

COVID-19 has changed the way we collaborate and communicate. It has also revealed the limitations of some of the digital collaboration tools people have had to use, including in sectors like education and healthcare. COVID-19 created a `rush’ to simply get functions online (classes, health consultations, staff meetings). But people in these sectors are now asking the question – how do we use these digital tools to make these interactions more immersive and engaging, and…

How do you know for sure that a router in your network has not been altered since you deployed it? Wouldn’t it be great if you could cryptographically challenge your router to provide its unique identity? In addition, what if the underlying OS could provide a secure mechanism to detect if the software had been tampered with during boot time and runtime? Networking equipment manufacturers are seeing an increase in supply chain attacks, which means…

2020 put network infrastructures to the test. Work from home and streaming video pushed network traffic loads into the stratosphere. More and more endpoints connected to the network, as enterprises pushed hard to digitize their service offerings, and the rate of cyber-security threats, which continue to present a significant business risk, skyrocketed. While communication service providers juggle these short-term challenges, they are also engaged in a long-term network transformation to speed up service delivery through…

Introducing Vanilla ISE – a simplified ISE GUI for endpoint technicians Some people prefer to begin with the end result, and reverse engineer their way backward. If that is the case, let me make your life easy – here’s a link to the Vanilla ISE GitHub repo. However, if you are interested in the approach we took, our thought process, and tools that led us to the end result – keep on reading! In this…
