log-pager

Overview

Lightweight security log forensics and blacklisting web interface, intended to provide a dashboard for threats. Displays log events as heatmap using tile plot, allowing user to click on a given period to drill down into the log. Performs asynchronous geolocation and reverse DNS resolution.

Threat intel and blocking

For each IP in the log, there is a button to pull intel about an IP, including port scans, whois, traceroute and ping graphs. There is also a button to add the IP to a blocklist if desired. The intent here is to supplement automated "fail to ban" approaches with the potential for manual permanent blocking by a human administrator.

Approach

The approach is to treat the log file itself as truth and run UNIX tool commands on the host (within a Docker container) to extract data from the log file directly, essentially running the kinds of local unix forensic commands a sysadmin would. This approach is intended to minimize the impact on the server, with no resources being used except when the web interface is actively being used.

Potential blacklist service

If enough people adopt this, the next step will be to build a service that would collect blacklisted IPs (if you voluntarily configured your instance of log-pager to forward blacklist items) and publicly provide provde aggregated blacklists based on crowdsourced human judgement, rather than algorithms. If you think this would be interesting, please reach out.

Docker image

This repo automatically builds a Docker image that can be pulled from the GitHub Container Registry. See the Packages tab in the GitHub repo for the latest version.

General usage

Mount the log files of interest as /access.log and /auth.log in the Docker container. Connect to the container on HTTP port 80 and the default interface will be served. There is no security or SSL provided as this is primarily intended as an auxilary container to be integrated with other containers and hosted behind a reverse proxy, such as Traefik. Right now this only work with CLF log files, but will eventually be made to work with at least standard auth logs, as well.

You can quickly stand up a fully functional demo using the docker-compose.yml file found in /test/stack.

Use with docker-compose

Here is an example docker-compose.yml file showing how to integrate with a reverse proxy (Traefik) to access logs for all proxy traffic. (Obviously, you'll want to have other services as well which I haven't shown here.)
