Automation is the name of the game when it comes to managing server configurations and ensuring consistency across your infrastructure. Puppet is a powerful configuration management tool that can help you achieve this goal effortlessly. In this guide, we’ll walk you through the process of installing and setting up Puppet Community Edition on Debian servers with a Debian Puppet Master.
In an era defined by the constant threat of cyberattacks, organizations are increasingly investing in robust cyber security measures. As part of this proactive approach, the Blue Team plays a pivotal role in safeguarding digital assets and sensitive information. We had an article about Red Teams, let’s investigate the role of the Blue Team now!
In the vast and treacherous seas of cyber security, threats come in all shapes and sizes. While phishing and malware attacks are commonly discussed, there’s a bigger fish in the ocean: “whaling” attacks. These are highly targeted and sophisticated cyber threats that aim to harpoon the biggest catch of all—senior executives and high-ranking individuals within organizations.
Containerization has revolutionized software deployment, and Docker Swarm provides a powerful solution for orchestrating and managing containerized applications. In this guide, we will take you through the step-by-step process of setting up and effectively using Docker Swarm on three virtual machines, and then extend it to include a load balancing proxy using Nginx. By the end of this tutorial, you’ll be equipped with the knowledge to harness the benefits of container orchestration and load balancing for your projects.
Docker networks are virtual networks created by Docker to enable communication between Docker containers, allowing them to connect to and communicate with each other or to non-Docker workloads. Containers inside the Docker network can talk to each other by sharing packets of information, and each container sees a network interface with an IP address, a gateway, a routing table, DNS services, and other networking details. By default, the container gets an IP address for every Docker network it attaches to, and when a container starts, it can only attach to a single network, using the –network flag. However, you can connect a running container to multiple networks using the docker network connect command.

In ethical hacking, security professionals utilize an array of tools to assess and fortify the security of digital systems. One such tool that stands out is Hashcat, a powerful password cracking/recovery utility. Hashcat enables ethical hackers to uncover vulnerabilities in systems by attempting to crack hashed passwords, allowing organizations to identify weak passwords and bolster their defenses.
In the digital age, small companies are increasingly becoming prime targets for cyber criminals due to their often limited security resources and vulnerabilities. To safeguard their digital assets and sensitive data, it is crucial for small companies to conduct regular security checks. Tenable Nessus Essentials, a powerful vulnerability scanner, is an ideal solution for these companies to enhance their security posture. In this post, we will explore how to configure Tenable Nessus Essentials for daily security checks, empowering small companies to proactively detect and address potential threats.
In the dynamic world of cybersecurity, organizations are continually striving to stay one step ahead of cyber threats. Among the strategies employed is the concept of Purple Teams, which seeks to combine the strengths of both Red and Blue Teams. While this approach appears promising, some concerns have arisen about their productivity. In this blog post, we will explore the role of Purple Teams, their potential benefits, and the factors that may hinder their productivity.
In today’s ever-evolving IT landscape, the need for self-service automation and precise scheduling has become significant. Enter Rundeck and Ansible, two formidable tools that empower organizations to speed up their infrastructure management. When combined with the containerization capabilities of Podman and the orchestration provided by Podman-Compose, you can create a robust automation environment that not only simplifies self-service tasks but also enables precise scheduling.
Common Lisp is a powerful and versatile programming language known for its expressive syntax and rich ecosystem of libraries. If you’re a seasoned Linux user, particularly on Debian-based distributions like Debian itself or Ubuntu, setting up a Common Lisp development environment with Emacs using SBCL (Steel Bank Common Lisp) is a straightforward process. I write this article because despite the elegance and functionality of Common Lisp the user base of the language is constantly shrinking.
In the technological art of cybersecurity, ethical hackers play a crucial role in safeguarding digital assets and personal information from malicious actors. Ethical hackers, also known as white hat hackers, utilize their skills to uncover vulnerabilities and weaknesses in systems, applications, and services, ultimately enhancing security. Contrary to popular belief, their approach extends far beyond brute force and password cracking.
In the world of DevOps, two buzzwords that frequently come up are Kubernetes and Docker. Both technologies have revolutionized the way applications are developed, deployed, and managed. While they are often used together, they serve different purposes and have distinct roles in the modern software development landscape.
Ansible Vault is a feature of Ansible that allows you to encrypt sensitive data such as passwords or keys in encrypted files, rather than as plaintext in playbooks or roles. This provides the ability to secure any sensitive data that is necessary to successfully run Ansible projects. Ansible Vault uses the AES 256 algorithm to provide symmetric encryption, which means that it uses the same password for encrypting and decrypting files. The ansible-vault command is the main interface for managing encrypted content within Ansible, and it is used to initially encrypt files and subsequently used to view, edit, or decrypt the data. Ansible Vault is especially useful if you have confidential data that you want to secure and prevent from being publicly exposed.
