Basics on Cisco DSL Router Configuration
Today I am going to talk about the DSL router basics and the configuration of the Cisco DSL router. People who are from the Routing and Switching background should have this as a basics level of learning. You can connect Cisco DSL router with the PC. A console connection is made with a rolled cable and connects the console port of the Cisco Digital Subscriber Line (DSL) Router to a COM port on a PC. The console cable that is included with the Cisco DSL Router is a flat light blue cable.
For more information on the pin outs of a rolled cable, or the pin outs of an RJ−45 to DB9 converter, see Cabling Guide for Console and AUX Ports.

- Connect the RJ−45 connector on one end of a Cisco console cable to the console port of the Cisco DSL Router.
- Connect the RJ−45 connector at the other end of the console cable to an RJ−45 to DB9 converter.
- Connect the DB9 connector to an open COM port on your PC.

Will Ransomware Die?
Ransomware has been one of the more prevalent security topics for past few years. Some probably think this form of digital destruction is here for the long haul. While this may be an accurate prediction, I can imagine a turn of events that would end this form of attack. To be clear, my theory is not that enterprise networks will plug every possible entry point. My prediction is that the ransomware business model COULD cease to be viable.
Let me expand on my position. For a business model to work, it has to have a monetization strategy. For ransomware, that strategy includes the victim sending money (typically bitcoin) to the attacker—trusting that they will be given the keys to decrypt their files. In this model, the victim has to trust their attacker [to do the right thing]. In and of itself, that seems to be an oxymoron and a plea in desperation.
So if these types of attacks fail to produce recovery options and gain widespread coverage, this trust is further eroded. To some degree this has already happened with Nyetya.

4 Main Design Principles of Mobile Networks
4 Main, Key Design Principles of Mobile Networks – I will explain the 4 key design principles of cellular networks in plain English. In fact I should have said, cell based systems as mobile networks may not be design based on cell based architecture. Let me explain what would be the other deployment […]

Declarative and Imperative Automation Thinking
Event driven or workflow driven automation for the uninitiated can appear daunting. With the rise of machine learning which adds more complexity to our field, simple rule driven automation feels more in reach than it ever has. This post aims to introduce you to a viewing lens for the world of great automation.
Converting processes in to workflows can be a tough task to accomplish and whilst this is relevant, it isn’t for this post. That’s one for another day but a great talking point and one that will be addressed.
The Layer Cake
Good automation tooling offers two views of the world; one high level that you pass arbitrary data around and one that handles interface implementation, which converts the arbitrary data to meaningful contextual data. In other words, a declarative and an imperative view, the ‘what’ and the ‘how’. The dimension that exists between the two can make or break the tool. If we have to care too much about how data is passed from one layer to the other, we’re not users, we’re more co-developers and it’s a kit not a tool.
Our Layer Cake model is simple at a high level. Two layers are enough to Continue reading
