Book Review: Defensive Security Handbook

Recently I purchased a few infosec books, one of them being the Defensive Security Handbook written by Lee Brotherston & Amanda Berlin. While this book was written back in April 2017, the information contained within is still very relevant today and will give the reader a sound footing when it comes to what you need to have as a secure baseline in your environment. There are 21 chapters that can be read from cover to cover, or each in isolation.

Thehive4 RC1 to RC2 Upgrade

With my Java issue sorted out now, here are the steps to upgrade TheHive from RC1 to RC2. This is a dirty upgrade, but since TheHive is still in Release Candidate status, we can get away with upgrading like this. Ordinarily you should ensure that you have your system backed up in case there are breaking changes. Stop TheHive service sudo service thehive stop Update apt repositories and upgrade May as well apply all the security updates while I am at it.

TheHive 4.0.0-RC2: Last error: Connection refused

I was so excited at the thought of all the cool new features that have popped up in TheHive v4.0.0-RC2 that I went straight onto my lab to give it a spin. Little did I know that my system was broken before I even started and I spent the best part of a few hours trying to figure out what exactly happened. For a brief moment I did consider burning the lab down and just rebuilding it, but I asked myself what would happen if this were a prod system?

TheHive in Docker

Docker is something that i’ve not fully embraced to date, I know, I know… I’m a little late off the mark, but as I get to know Docker more, I can see that it has some worthwhile advantages for me in some of the projects I use and generally getting to know technology is never a bad thing. For instance, why spin up a single server for a service that only has 1 of the 65535 ports used when 99% of the time that server will most likely be idle.

Adding Traefik Reverse Proxy to Opencti

Well this one was a bit of a learning experience for me. You see I have dabbled in the past with Traefik which seems to fit naturally when it comes to reverse proxy and Docker, but my efforts have come up short in the past through no fault but my own. Perhaps it was the fact I was trying to run before I could even crawl. Not to worry though.

Adding MISP to OpenCTI

While im still getting myself familiar with OpenCTI and building out an actor profile, I thought I’d link it up with my MISP instance. OpenCTI provides a connector to do this which will require an update to the docker-compose.yml file and an update of the stack. If you have been following along, this post is a continuation of Installing OpenCTI. To add the MISP connector, login to Portainer and select Stacks, opencti.

OpenCTI Installation

OpenCTI is an open source Cyber Threat Intelligence platform that provides a powerful knowledge management database for storing, organising and sharing knowledge about cyber threats and uses the STIX2 schema for it structure. It has been designed for CTI analysts. The platform is built on Modern technologies of Grakn, GraphQL, Elastic, RabbitMQ, Redis and React. The project is available as a docker image which make installation simple. While I’m probably not going to do the best job of talking up the full feature set of this platform, you can view more about it on their website and github page.

TheHive V4 - More Config

This post is a continuation of TheHive v4 RC1 in that I am providing the instructions to add Internal Authentication to Cassandra as well as a reverse proxy so we can connect back to TheHive with https. Add Internal Authentication to Cassandra It is recommended that you don’t allow access to the cqlsh unless there is some sort of authentication mechanism attached to it. There are too many horror stories of databases being dumped, and the internal authentication will make it that little bit harder to access from the cqlsh shell.

TheHive v4 RC1

TheHive version 4 RC1, it’s here, its been here for a solid few weeks and I’m only just getting around to checking it out now. The new update looks to include a few nice features and a welcome back end technology refresh which should keep the platform in support for a good while yet. At this stage, I would not suggest attempting to either upgrade your existing version 3 installations to version 4, or run a clean install as your main case management production system if you’re just starting out, but get to know this version by spinning up a new virtual machine because when the time comes around, you will give yourself a good leg up.

UniFi Site Migration

I’ve been a little absent of late. I’ve been quite busy at home having to get a few last minute things, like additional landscaping, pressure cleaning concrete, putting together flat pack furniture for my house in preparation for sale. Which brings me to why I’m writing this this post. I am a huge UniFi fan having multiple devices in my home network installation which have been flawless since installation. A few of those components include a CloudKey controller and a number of UniFi Protect cameras which naturally became a bit of a selling point for the house.

Cortex 3.0.0 to 3.0.1 Upgrade

Cortex 3.0.1: The better logging edition has been released now. I am quite surprised that the developers were able to release a point upgrade out while they are working on the new major release of TheHive but I welcome it as it brings a number of fixes and enhancements which you can read about on TheHive project Blog. Some of the bug fixes will make my life easier as some logging issues have been corrected which will make testing and developing responders for Cortex less painful.

Welcome to 2020

Well what a write off of a year so far. Over the Xmas break, I wasn’t able to get in as many hikes as I would like due to the terrible fires we have had over the last few months. Given the air quality has been rated as hazardous, I’ve erred on the side of caution, not wanting to fill my lungs with it. I was however able to write up the 3 that I did.
