In this article, we present an initial example of executing mass commands using Ansible on Cisco IOS devices. We will utilize the pre-configured “Cisco Legacy Core-Access topology” lab available in the repository DevNetOps course material:
Ansible is distributed as a Python module installable via PIP. The installation process is straightforward but warrants some considerations. Typically, the automation host, the system from which all automation scripts originate, is one of the most critical systems within an infrastructure.
The first step to work in the IT field today is to set up a laboratory. EVE-NG (formerly UNetLab) can be used for network, network security, and automation labs. EVE-NG is based on Ubuntu Linux 20.
Operating on a data center (DC) or backbone Internet Service Provider (ISP) typically involves a significant amount of human effort, resulting in operational costs that are often overlooked. However, these costs can be optimized by harnessing the power of automation to handle simple and repetitive tasks efficiently.
This is the third part of my IaC overview based on a personal experiment: building Cyber range using the IaC paradigm. Here is the first and second parts. A few weeks ago I met Spacelift and I had the chance to test their product.
This is the second part of my IaC overview based on a personal experiment: building Cyber range using the IaC paradigm. Here are the first and third parts. In a pure design perspective, the client-to-site VPN approach is still the best.
This is the first part of my IaC overview based on a personal experiment: building Cyber range using the IaC paradigm. Here are the second and third parts. During my Twitch session, I’m used to offering a practical lab to attendees.
Years ago I worked on a data center migration project. I was in charge to review network documentation, and automating the configuration, testing, and migration phases. There is no chance to review dozens of switches manually, so I wrote some Python scripts to get neighborship and configuration from switches, drawing Visio diagrams.
I usually don’t write about OSINT techniques, I think that before approaching OSINT we should speak about ethics and respect. By the way, some OSINT automation techniques are harmless: if you don’t know what you have to search for, you won’t be able to get anything regardless you are automating or not.
Security assessments are part of my daily job, and automation is part of my mindset. CIS Controls provides a set of standard controls that should be checked on… anything. To be specific CIS also provides a benchmark (a sort of step-by-step guide) for many environments.
