DeepSec 2021 Press Release: DeepSec and DeepINTEL Publish Conference Program

Sanna/ September 23, 2021/ Conference, DeepIntel, Press

IT security has a lot of catching up to do, digitization is on an insecure foundation. The COVID-19 pandemic will celebrate its second birthday next year. Our everyday life has become more dependent on digital tools and platforms. If you want to rely on the convenience of the digital world, data and communication must not be threatened by weak points. Unfortunately, this is not the case, which is why the annual DeepSec IT security conference will again address threats for companies and authorities this year. Expectations Digitization is largely viewed uncritically as a metaphorical bringer of salvation. It should make work easier, make information more accessible, reduce administration and, in principle, solve or at least reduce problems in every area. The term Artificial Intelligence is often used when promoting the future. In the key

DeepSec 2021 Training: How to Break and Secure Single Sign-On (OAuth and OpenID Connect) – Karsten Meyer zu Selhausen

Sanna/ August 23, 2021/ Training

Implementing single sign-on has huge benefits in general. It allows to design the registration and login process for users to be as simple as possible, and enables applications to be connected to social networks. Although OAuth and OpenID Connect are established as today’s common standards, serious attacks on them have been discovered within recent years. These attacks exploit the complexity of the underlying standards and implementation flaws, and allow attackers to authenticate themselves as arbitrary users or to access confidential user data. By doing so, attackers can potentially read, manipulate, or delete data of arbitrary users across these applications. Due to the critical role that single sign-on fulfills in applications nowadays, it is important to understand and address pitfalls when using OAuth and OpenID Connect. However, automatic security scanners are not able to properly
