How To Configure An Apache SSL Reverse Proxy on Linux?

~ Tom's IT Cafe ~ Leave a comment

What is Apache?

Apache is a free and open-source cross-platform web server software that allows users to deploy their websites on the internet. It was launched in 1995 and has been the most popular web server on the Internet since April 1996.

What is a reverse proxy?

A reverse proxy is a server that sits in front of web servers and forwards client requests to those web servers. It acts as an intermediary, intercepting and inspecting incoming client requests before forwarding them to the web server. Reverse proxies can provide additional levels of abstraction, control, security, and performance optimization. They are commonly used for load balancing, web acceleration, and to hide implementation details about the web servers.

What is SSL?

SSL, or Secure Sockets Layer, is a protocol for establishing authenticated and encrypted links between networked computers. Its current iteration is called TLS (Transport Layer Security).

How To Create A Scalable Jenkins CI/CD Environment Using Containers?

~ Tom's IT Cafe ~ Leave a comment

Jenkins is a platform for creating a Continuous Integration/Continuous Delivery (CI/CD) environment. It is written in Java and provides support for various version control tools such as Git, running Bash scripts and Windows batch files, building Ant and Apache Maven-based projects, and more. Jenkins helps build, test, and continually deploy software. It is an open-source system and one of the leading automation servers. Jenkins requires scripting some automation steps, but it provides a fast and robust way to systematize the software development lifecycle. The program runs web containers and plugins, such as Apache Tomcat, and helps manage lifecycle and access rights requests. Over 1700 plugins for Jenkins enrich the software integration, automation, and delivery processes and provide a customizable environment. Jenkins is used for the whole software delivery pipeline, including deployment.

Detecting Rootkits with RKHunter

~ Tom's IT Cafe ~ Leave a comment

In the ever-evolving landscape of cyber security, the importance of safeguarding your Unix-based systems cannot be overstated. Malicious actors continuously seek new ways to infiltrate and compromise your systems. One particular threat that often goes undetected is the rootkit—a sophisticated malware that conceals its presence by subverting system functions. To counter this menace, one valuable tool in your cyber security arsenal is RKHunter, short for Rootkit Hunter. This open-source, command-line utility is specifically designed to identify and help mitigate rootkit infections on Linux and other Unix-based systems.

Mastering Docker Networking: Exposing Ports Only to Other Containers

~ Tom's IT Cafe ~ Leave a comment

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.

A Deep Dive into Ansible Vault: Safeguarding Your Sensitive Data

~ Tom's IT Cafe ~ Leave a comment

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.

Securing Ansible Automation with Single Entry Points: SSH Jump Hosts

~ Tom's IT Cafe ~ Leave a comment

Using SSH jump hosts (also known as bastion hosts or SSH gateways) with Ansible allows you to securely access and manage servers in a remote network or behind a firewall. Jump hosts act as intermediaries, forwarding your SSH connection to the target hosts. You can configure Ansible to use jump hosts for managing remote servers. Here’s how to set it up:
