Ansible is allowing me to control some devices, so what can I do with it to improve security on my Pi network? Note: This post forms part of the my collection of posts on Ansible including installation; SSH set-up and the basics of a playbook/commands. Chage Raspbian has a function called chage that lets you see … Continue reading Ansible – Looking At Basic Security (Raspberry Pi)
With Ansible installed and connections to other devices set up, it is now time to have some fun and start using Ansible. For this project I am using a Raspberry Pi 3 running Raspbian OS (Buster) with Ansible installed and two Raspberry Pi Zero Ws running Raspbian OS (Buster). The two previous blog entries discussed … Continue reading Ansible – Looking at commands & Playbooks (Raspberry Pi)
In the previous post I walked through installing Ansible on a Raspberry Pi and finished at the point of the Ansible inventory being set up but needing some SSH. For this part of the project I am using: A Raspberry Pi 3 with Ansible installed, running Raspbian OS (Buster). This is my controller. 2x Raspberry Pi … Continue reading Ansible Setting Up SSH (Raspberry Pi)
My professional day-to-day role sees me administrating Windows OS based systems using Microsoft System Centre Configuration Manager (SCCM) and Active Directory/Group Policy. Knowing what tools are available to manage so many Windows systems at once I'm looking for something similar to manage several Raspberry Pi (Linux) systems at once. Previously I have looked at network … Continue reading Installing Ansible (Raspberry Pi)
Raspbian Buster is available and, if like me, you cannot currently afford to upgrade to a Raspberry Pi 4 and you don't want to install Buster from fresh then it is time to do an in place operating system (OS) upgrade. https://www.youtube.com/watch?v=tp50DoA6hCk&feature=youtu.be I am going to doing this in place upgrade on my Raspberry Pi … Continue reading Raspbian OS Buster Upgrade (Raspberry Pi)
In the previous post I discussed the basics of setting up the UFW firewall on a Raspberry Pi, now I'll dig into some of the slightly more advanced features. Numbered Rules Every allow, deny or limit that UFW is told about is remembered as a numbered rule. To view the numbering enter: sudo ufw status … Continue reading Configuring A Firewall (Raspberry Pi)
If you are opening your Raspberry Pi to the internet then security should be a concern/part of your project design. So today I'm going to look at configuring a software firewall called UFW. Installing UFW Installing a firewall on the Raspberry Pi (Raspbian) is accomplished easily via the terminal and the following line: sudo apt … Continue reading Installing A Firewall – Basics (Raspberry Pi)
With my adventures looking at Java I have also been using a different IDE (Integrated Development Environment) called IntelliJ on my Macbook. However I also want to look at using Java on my Raspberry Pi. The Raspbian OS (Stretch) comes with a Java IDE called BlueJ, which is designed around Java and supporting beginners to Java. … Continue reading Installing IntelliJ IDE On Raspberry Pi (Java / Raspberry Pi)
Today I am having a quick play with the socket library in Python, and using it on my Rasperry Pi as a port scanner to check for vulnerabilities on devices connected to my home network. Yes, I know there are other tools available (such as nmap) that can do this but I wanted to see … Continue reading Creating A Port Scanner (Python / Raspberry Pi)
With the Raspberry Pi running Apache Tomcat it is time to secure it. HTTP (non-secure) traffic may be okay for a closed home/test environment but for a work/production environment HTTPS (secure) should be used. To show how to turn HTTPS on for Tomcat I will be using a self-signed certificate. If you are using a public … Continue reading Securing Apache Tomcat (Raspberry Pi)
