Introduction # In a previous post I have talked about introduction and basic usage with iptables. I did some more research on the subject and I found out more information about it which I would like to share with you.
Best Practices for Configuring iptables Rules # When configuring iptables rules, it’s important to follow best practices to ensure that your firewall is effective and secure. Here are some best practices for configuring iptables rules:
Introduction # Not until recently, I was compelled to learn iptables when I was working with Firecracker VM. iptables is a tool to manipulate network packets.
Iptables is a powerful and versatile firewall tool that is used to protect and secure networks. It is an open-source program that is installed on Linux-based operating systems. Iptables works by inspecting and filtering network traffic based on a set of rules. These rules define what traffic is allowed and what is blocked, based on criteria such as the source and destination IP address, port number, and protocol.
Introduction # Why rootless docker?
“Rootless” Docker refers to running Docker containers without granting the Docker daemon full root privileges on the host system. This can provide added security, as it reduces the potential attack surface and damage that could be caused by a malicious or compromised Docker daemon.
In normal Docker usage, the Docker daemon runs as the root user, which means it has complete access to the host system. While this is necessary for many Docker features and functionality, it can also represent a significant security risk, especially when running untrusted or unknown containers.
Introduction # We have previously seen how you can Spin up your own VPN on Ubuntu 20.04. Among many benefits, one of the benefits of the VPN is geographical anonymity.
Today we are going to discuss and set up yet another benefit. We are going to tweak our VPN server set up a little bit to enable ad-blocker out of the box. Meaning that you won’t have to install an ad-blocker on your browser. It will be enabled connection-wide. You won’t be seeing any ads on devices that you can’t control ads on, like smart TV, etc.
Recap # We have already seen how to enable HTTPS on a domain if you have a VPS and you are using Nginx. In one other post we have also talked about getting started with Ansible in which I wrote about basic concepts in Ansible such as inventory, module, playbook. We have also talked about Ansible Roles which are about directory structures.
Introduction # I have already posted about how we can automate installation of Jenkins & Nginx with Ansible. I have also done a post where I talk about how to enable HTTPS on a non-wildcard basis i.e. only for the root domain and not on subdomain.
Today I’ll go through how go get and configure a HTTPS certificate from Let’s Encrypt for all the subdomain. I’ll automate all these using Ansible.
Introduction # There are a plenty of VPN providers out there. What’s common between all of them? You can’t trust them. They may have a no-log policy but as a company, there is always a tendency that they might share our browsing data to some third party. In this post you’ll learn how you can spin up your own VPN with Amazon AWS.
Introduction # In 2014, Google hinted that they are running tests taking into account whether sites use secure, encrypted connections as a signal in our search ranking algorithms. This means it will affect SEO in some way. Today in the age of HTTP2, https is default. Default in the sense that many server software will only allow HTTP2 when https is configured.
