Interested in sharing your MISP usage experiences? How did you integrate MISP in your incident response workflow? Have anything to say about threat sharing in general?
There’s a BelgoMISP Meeting 0x01 for all Belgian MISP users. Submit your proposals via Github or contact us via Twitter.
I published an article on the IBM SecurityIntelligence blog on how to Measure and Improve the Maturity of Your Incident Response Team
The post describes how you can create an incident response development plan and which proven frameworks exist to assist you with this. I then provide more details on the NIST and the Global CSIRT Maturity framework. The latter, which is based on SIM3 and the ENISA three-tier approach, is then covered in more … Read more.
I published an article on the IBM SecurityIntelligence blog on How PR Teams Can Prepare for Data Breach Risks With Incident Response Planning
The post describes how you can take control of the incident response communication, how to prepare for incidents by identifying your stakeholders and preparing communication templates and which tooling is available for communication during a security incident.
Attributes in MISP have a boolean flag to_ids allowing you to indicate if an attribute should be used for detection or correlation actions. According to the MISP core format data standard, the to_ids flag represents whether the attribute is meant to be actionable. Actionable defined attributes that can be used in automated processes as a pattern for detection in Local or Network Intrusion Detection System, log analysis tools or even filtering mechanisms.
Unfortunately attributes marked … Read more.
Installing PyMISP can sometimes be difficult because of a mixup between Python2 and Python3 libraries or problems with pip install. To solve this I created a PyMISP docker container that allows you to run the scripts in the example directory, without the need of installing PyMISP itself.
The Dockerfile is in the Github repository PyMISP-docker. The docker container is available via Docker Hub cudeso/pymisp.
In a previous post I covered how to create MISP data … Read more.
The MISP API includes a couple of features that you can use to report on the type of data stored in the database. For example the User statistics or Attribute statistics give a pretty good overview. Unfortunately, as of now it’s not possible to limit the output of these functions to a specific timeframe. For my use case I’d like to report on the MISP data statistics for the last month. The information that I … Read more.
For a new project I had to identify the source network of visitors of an http site, served via Apache. I did not need their individual IP address. This is something you’ll encounter when dealing with logs in light of the GDPR and having to store only the minimum amount of personal data necessary.
In essence it meant I needed a way to store the log requests and remove the last octet of the IP … Read more.
I run a couple of honeypots which allow me to map some of the bad actors and scanners on the internet. The most popular honeypots are Dioanea, Cowrie (ssh, previously kippo) and Conpot (ICS). So far I’ve not really used this honeypot data that much for defensive purposes but a recent writeup on using ModSecurity and MISP gave me inspiration to transform this data into information that I can use as a defender.
The core … Read more.
I published an article on the IBM SecurityIntelligence blog on How to Patch BlueKeep and Get to Know Your Company’s Critical Assets
The post has a very brief introduction to Remote Desktop Protocol and what caused the BlueKeep vulnerability. I then cover how to protect against blueKeep, which measures you can take to be prepared for the regular patch Tuesday and which tools and techniques are available to keep track of your (vulnerable) assets.
I sometimes contribute to open source projects on Github. The workflow then often consist of creating a fork, adding my own code and then submitting pull requests.p
Unfortunately sometimes when you do this the upstream (meaning, the ‘original’ repository) has changed so much that it’s not possible to easily submit (or include) your changes. You then need to sync your fork with the upstream repository.
For what concerns the repositories related to MISP, these are … Read more.
