Introduction In this previous post, I detailed my transition from WordPress to Hugo static sites. This post discussed hosting the site locally in a Docker container web server and exposing ports 80 and 443 to a reverse proxy on my DMZ network. Today, I will show you how you can host your Hugo static site on Cloudflare–FREE. This will absolve your responsibility to host the site, expose ports to the public, and deal with SSL certs. Cloudflare will automatically take care of all of this for you, and Clouflare will even automatically build your site from a Git repo when changes are pushed. ...

Introduction This post will cover how to set up a Docker container of Cloudflared on your internal network to provide a private tunnel from Cloudflare to your internal resources. After setting up the Cloudflared tunnels, you will no longer need to expose ports 80 and 443. This post assumes you currently have a vibrant and functioning internal network with a reverse proxy (in my case, Nginx Proxy Manager) already configured. Additionally, this post assumes you have a Cloudflare account with the ability to modify DNS records for your domain(s). ...

Introduction In this previous post, I showed how to connect to a Unifi router with HTTPS, effectively ridding you of the tedious words, “Your connection is not private.” However, the method shown in that post directs your connection to an external DNS server (e.g., CloudFlare) in order to resolve your Unifi router. This adds some latency by requiring your traffic to flow out and in rather than staying local. Additionally, it requires opening some ports externally. While this is not necessarily bad, it certainly increases the risks and attack surface of your network. ...

Introduction OSSIM is a powerful open source security information and event management (SIEM) operating system. AlienVault OSSIM is the open source version of AlienVault, which is sold by AT&T. I have used OSSIM in professional deployments in the past, and I currently use OSSIM for vulnerability scanning, asset management, and security alerts. OSSIM can often be overly complicated to set up and install, and the documentation available for troubleshooting is sparse. I have learned a lot of great tricks over the years by trial and error. ...

Introduction Logging and traffic monitoring are of utmost importance in information security. Having searchable stored logs can allow visibility into a variety of critical activities related to a data breach. For example, individual computer event logs can provide insight into an attacker’s lateral movement within an environment. Active Directory authentication logs can provide more detail into this lateral movement and even help to establish a timeline of this movement. Firewall logs can provide insight into an attacker’s first contact or the first time an attacker utilized a particular command or control domain. NetFlow logs allow visibility into how a user interacts with other devices internally. ...
