Cyber Resilience Strategy Changes You Should Know in the EU’s Digital Decade

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 includeRead more.

Use Elastic to represent MISP threat data

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 attributeRead more.

Cybersecurity Ethics: Establishing a Code for Your SOC

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 andRead more.

5G – 101

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:

Handle phishing e-mails with a phishing alert button and TheHive

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.

How to Support Defenders with the Permissible Actions Protocol

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 acceptRead more.

Difference between MISP REST API search for events and attributes

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 weRead more.

Mindmap Demystifying the “SVCHOST.EXE” Process and Its Command Line Options

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.

From threat intelligence to client scanning

An antivirus solution is an indispensable component in your defence arsenal but it does not protect you against all threats. Complimentary to an antivirus is Loki, an open-source IOC scanner. Loki is a scanner that allows you to search for intrusion activity such as

Network connections to C2 servers or malicious domains; Presence of files related to APT activity; Process anomalies such as malicious implants or patches in memory ; Credential dump activities; Checks forRead more.

A walkthrough of Watcher

One of the nice things of working in infosec is that there is always a new tool available to make your work easier. It can also cause a lot of frustration, as there is yet another new tool that you need to master. A tool I recently discovered is Watcher, a platform for discovering new cybersecurity threats targeting your organisation. Some of its key features include

Detecting emerging trends via social networks and RSS feeds;Read more.
