DeepSec2019 Training: Incident Response Detection and Investigation with Open Source Tools – Thomas Fischer & Craig Jones

Sanna/ November 20, 2019/ Conference

Defences focus on what you know! But what happens when the attackers gain access to your network by exploiting endpoints, software or even you people. Under the assumption that you have been breached, how do you work backwards to gain knowledge of what happened? How can you find those adversaries in your infrastructure? IR detection and response relies on a structured process of identifying observables and collecting evidence. One aspect of this is the practice of proactively seeking out evil in your infrastructure, finding needles in haystacks that link to other needles and unveiling how an organization was compromised and possibly even answering the “why?”. This is commonly referred to as Threat Hunting. In this hands-on training participants will learn about the basic building blocks for an IR detection and investigation programme. The training

DeepSec 2019 Training: Threat Hunting with OSSEC – Xavier Mertens

Sanna/ October 26, 2019/ Training

OSSEC is sometimes described as a low-cost log management solution but it has many interesting features which, when combined with external sources of information, may help in hunting for suspicious activity occurring on your servers and end-points. During this training, you will learn the basic of OSSEC and its components, how to deploy it and quickly get results. The second part will focus on the deployment of specific rules to catch suspicious activities. From an input point of view, we will see how easy it is to learn new log formats to increase the detection scope and, from an output point of view, how we can generate alerts by interconnecting OSSEC with other tools like MISP, TheHive or an ELK Stack / Splunk / … and add more contextual content with OSINT feeds. We

DeepSec 2019 Training: Analysing Intrusions with Suricata – Peter Manev & Eric Leblond

Sanna/ September 18, 2019/ Security, Training

Defending your network starts with understanding your traffic. More than just an IDS/IPS, Suricata can provide the visibility to solve incidents quickly and more accurately by enabling context before, during, and after an alert. In this course, attendees will learn the skills required to identify, respond and protect against threats in their network day to day as well as to identify new threats through structured data aggregation and analysis. Hands-on labs consisting of real-world malware and network traffic will reinforce the course’s concepts while utilizing the latest Suricata features. Come and see what you’ve been missing in your network and unlock the full potential of network security, detection, and response with Threat Hunting with Suricata at the DeepSec 2019 training. In this course, students will learn through a combination of lecture and approximately 15

DeepSec 2016 Talk: I Thought I Saw a |-|4><0.- Thomas Fischer

Sanna/ October 21, 2016/ Conference, Development, Security

Threat Hunting refers to proactively and iteratively searching through networks or datasets to detect and respond to advanced threats that evade traditional rule- or signature-based security solutions. “But what does this really mean?”, asks Thomas Fischer. “And what real impact does it have on the security team? Can we use threat hunting to provide a process to better detect and understand when you’ve been breached?” More and more security data is being produced and usually aggregated into a central location or body to hopefully take quick and informed decisions on attacks or compromises amongst a mountain of data. When you start to include data gathered from your endpoints the amount of data starts to explode exponentially. This level of data provides us with a large amount of visibility. But is having visibility enough? What
