Ez a blogposzt a második egy három részes sorozatból mely a gépi tanulás adatvédelmi kockázatairól kíván közérthető nyelven egy átfogó képet nyújtani. Az első egy bevezető volt a gépi tanulás világába, ez a létező támadásait öleli át, míg az utolsó rész a lehetséges védekezéseket mutatja majd be.

Certificate Transparency – the current landscape in Hungary
This blog post was written by Márton Horváth who worked on implementing a monitor for Certificate Transparency logs in the context of his student semester project. As a proof-of-concept, he used the monitor he created to collect information about logged certificates issued in Hungary or issued to Hungarian web sites. This blog post contains the main findings of the analysis of those certificates. Continue reading Certificate Transparency – the current landscape in Hungary
Linux integrity monitoring on the Raspberry Pi
This blog post, written by István Telek, is the last post in a series of blog posts on transforming the Raspberry Pi into a security enhanced IoT platform. This last post describes how we implemented a very basic integrity monitoring function as a trusted application running in OP-TEE. Continue reading Linux integrity monitoring on the Raspberry Pi
Enabling WiFi and converting the Raspberry Pi into a WiFi AP
This blog post, written by Márton Juhász, is the fifth in a series of blog posts on transforming the Raspberry Pi into a security enhanced IoT platform. This post specifically will explain how to convert the Raspberry Pi into a WiFi access point such that it can perform some gateway-like functionality. First, we describe how to enable WiFi and then how to enable other software components to make the Pi an access point. Continue reading Enabling WiFi and converting the Raspberry Pi into a WiFi AP
OS hardening on the Raspberry Pi
This blog post, written by Márton Juhász, is the fourth in a series of blog posts on transforming the Raspberry Pi into a security enhanced IoT platform. Previous posts discussed building a custom Linux system with Buildroot, installing OP-TEE, and verified boot on the Raspberry Pi. This post will describe some OS hardening options you can use to reduce the attacks surface. Continue reading OS hardening on the Raspberry Pi
Verified boot on the Raspberry Pi
This blog post, written by István Telek, is the third post in a series of blog posts on transforming the Raspberry Pi into a security enhanced IoT platform. It describes how you can implement a verified boot process on the Raspberry pi. Continue reading Verified boot on the Raspberry Pi
Using Buildroot to create custom Linux system images
This blog post, written by Szilárd Dömötör, is the second post in a series of blog posts on transforming the Raspberry Pi into a security enhanced IoT platform. The first post explained how to build and install the default OP-TEE implementation for the Raspberry Pi 3. This one describes how you can build your own custom Linux system (with OP-TEE) using the Buildroot environment. Continue reading Using Buildroot to create custom Linux system images
