For cyber security training, it's beneficial to create accounts on well-known cyberranges that offer both free and paid training:
ReadIf you ever tried to set up a web application on your local machine with a secure connection (using HTTPS), you likely generated self-signed TLS certificates. When you create your own self-signed certificate, or even when the application you're using generates the certificate itself, your operating system (OS) will likely not trust the certificate. Consequently, also your other applications will not trust the certificate.
ReadBij Cylab zijn we op zoek naar een voltijdse onderzoeker in het domein van cybersecurity met een masterdiploma cybersecurity, informatica, computerwetenschappen of equivalent. Iets voor jou? Lees vooral snel verder! Voor een eerste project, onder de noemer "AI for Cyber", is het de bedoeling om verschillende nieuwe technieken uit het domein van artificiële intelligentie (AI) te bestuderen, vergelijken en toe te passen bij de bescherming van onze systemen tegen cyberaanvallen.
ReadNous recrutons un chercheur en cyberdéfense, à temps plein, avec un Master en Cybersécurité, Informatique ou équivalent. Pour un premier project, nommé « AI for Cyber », nous planifions d’étudier et comparer les différentes/nouvelles techniques d’Intelligence Artificielle (IA), et de les appliquer dans la protection de nos équipements actifs contre les cyber attaques.
ReadInterpreting a 1-D array of pixels is not possible by the human eye. And yet such data is available in several circumstances, like the dump of pixel arrays from RAM or disk, the availability of image files in RAW format (without the width) or when solving a Capture-The-Flag cybersecurity challenge with images.
ReadArangoDB Graph database Network analysis and visualization Python
In this post we introduce the basics of a graph database and how to access it from Python. The database system used for storing and querying the data is ArangoDB, which was briefly described in a previous blog post. The Python driver of choice, as referenced in the official documentation, is Python-Arango; which can be accessed via its GitHub page.
ReadYou have heard of RDBMS, for Relational Database Management System, or may even intuitively associate the word "database" with a tabular representation of data that you can query using a language such as SQL. Depending on your technical affinity, or the scale of your problem, you would then turn to your tool of choice to store and access your data in a CSV text file, a spreadsheet, ... or table(s) inside a proper database. Ouch! Who says that one of those is better than another? And why even learn about anything else than a tabular model?
ReadThis week we participated, with the colleagues from Cyber Command, in the milCERT exercise organized by the European Defence Agency (EDA). During this exercise the participating teams get tested in a task driven response & investigation activities on full-scale IT Infrastructure live fire environment.
ReadImage format testing is a necessary action for digital preservation to ensure that the data will be readable in the long term. It may also be part of the solution to detect image manipulation for cybersecurity defense or in Capture-The-Flag exercises.
ReadIntrusion Detection Visual Analytics APT Detection
The constant stream of data produced daily, the complicated environment and the need for quick reaction to malicious attacks make the life of cyber defense analyst a living nightmare. Many wonder how are we supposed to be able to review the gigabytes of logs produced daily, how can we manage to analyze them all and extract valuable insight into what is happening in the network?
ReadThe creation of the Cyber Defence Lab was an incremental process. So it's hard to define a precise birth date. There is actually only one date that can be seen as our birth date: the day we registered our domain name cylab.be. And that was on 21 October 2016. So we turn 7. Happy birthday to us!
ReadDid you already want to analyse traffic of a specific application, but this traffic is encrypted using TLS? You start wireshark and then stumble upon this very annoying display where you only see encrypted TLS traffic.
