MISP correlations are a way to find relationships between attributes and indicators from malware or attacks campaigns. Correlation support analysts in detecting clusters of similar activities and pivot from one event to another.
When the volume of data in your MISP instance grows, the number of correlations can however explode and make your system less responsive. I cover some approaches that you can use to stay in control.
Correlation basically is a way for … Read more.
I published an article on the blog of the MISP project on how to create your own custom object: Creating a MISP Object, 101. This is a follow-up to a previous post on how to create your own MISP galaxy or MISP cluster (Creating a MISP Galaxy, 101).
I published an article on the IBM Security Intelligence blog : Cyber Resilience Strategy Changes You Should Know in the EU’s Digital Decade. The article describes the new EU Cybersecurity Strategy and one the proposal for a revised Directive on Security of Network and Information Systems
The EU Commission attempts to improve cyber resilience with the NIS2 Directive and provides an overview of cyber resilience challenges for 5G and IoT. Other topics discussed include … Read more.
In this post I go through the process of representing threat data from MISP in Elastic. The goal is to push attributes from MISP to Elastic and have a representation with a couple of pretty graphs. This is an alternative approach to using the MISP dashboard (and MISP-Dashboard, real-time visualization of MISP events).
The Filebeat component of Elastic contains a MISP module. This module queries the MISP REST API for recently published event and attribute … Read more.
I published an article on the IBM Security Intelligence blog : Cybersecurity Ethics: Establishing a Code for Your SOC. The article describes the dilemmas you can face when working in a SOC or doing incident response work.
The articles describes Cybersecurity Ethics Guidance Frameworks, Best Practices and a Practical Approach for Cybersecurity Ethics, including a set of commandments to adhere. For example
Do not use a computer to harm other people. Protect society and … Read more.
A short introduction on 5G. What is 5G, why do we need it and where will it be used?
5g 101 from Koen Van Impe
If you want to read about the security threats on 5G then these are a couple of interesting resources:

Your users are the first line of defence against threats, especially for what concerns phishing. One of the ways to get more involvement is offering a simple and easy way to report suspicious messages, such as phishing e-mails. You can do this via a phishing alert button that allows users to notify the helpdesk of a suspicious message. The technology behind such a button is straightforward:
Forward the message; Remove the message from the inbox. … Read more.
In a previous article I described how to defend with the courses of action matrix and indicator lifecycle management. The courses of action matrix describes passive and active actions that defenders can take with a varying type of impact on the attacker (or intrusion). The Permissible Actions Protocol or PAP achieves something similar, but with a focus on what defenders are allowed to do.
PAP is a protocol that describes how much that we accept … Read more.
MISP includes a powerful REST API that allows you to automate the dissemination of threat intelligence and threat data. If you aren’t familiar with the API you can explore its features (and the inline documentation) via Event Actions, REST client. In the latest versions of MISP the REST API client supports autocompletion, which is useful if you want to search for events or attributes with specific tags. And these tags are the vocabularies that we … Read more.
Nasreddine Bencherchali published an article on Demystifying the “SVCHOST.EXE” Process and Its Command Line Options where he describes how the svchost.exe process works, the different command line flags it uses and which two registry keys are important. For my own notes I documented his article in a mindmap.
