If you follow me, you probably already know that I’m a big fan of OSSEC. I would like to thank 44Con for accepting my next training! If you are interested in learning cool stuff about OSSEC and how to integrate it with third-party tools/sources, this one is for you! OSSEC
I published the following diary on isc.sans.edu: “Suspicious Endpoint Containment with OSSEC“: When a host is compromised/infected on your network, an important step in the Incident Handling process is the “containment” to prevent further infections. To place the device into a restricted environment is definitively better than powering off the system
After the 2018 DeepSec edition in November and the BruCON Spring Training in April, I’m happy to come back on the DeepSec 2019 schedule! 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
I’m in Washington, waiting for my flight back to Belgium. I just attended the 2019 edition of the OSSEC Conference, well more precisely, close to Washington in Herndon, VA. This was my first one and I’ve been honoured to be invited to speak at the event. OSSEC is a very
I published the following diary on isc.sans.edu: “Tracking Unexpected DNS Changes”: DNS is a key element of the Internet and, regularly, we read new bad stories. One of the last one was the Department of Homeland Security warning about recent DNS hijacking attacks. Indeed, when you want to visit the website ‘isc.sans.org’, you
I published the following diary on isc.sans.edu: “Using OSSEC Active-Response as a DFIR Framework”: In most of our networks, endpoints are often the weakest link because there are more difficult to control (example: laptops are travelling, used at home, etc).They can also be located in different locations even countries for
My training submission has been accepted at the BruCON Spring Training session in April 2019. This training is intended for Blue Team members and system/security engineers who would like to take advantage of the OSSEC integration capabilities with other tools and increase the visibility of their infrastructure behaviour. OSSEC is sometimes described as
I published the following diary on isc.sans.edu: “Hunting for Suspicious Processes with OSSEC“: Here is a quick example of how OSSEC can be helpful to perform threat hunting. OSSEC is a free security monitoring tool/log management platform which has many features related to detecting malicious activity on a live system like the
I’m proud to have been selected to give a training at DeepSec (Vienna, Austria) in November: “Hunting with OSSEC“. This training is intended for Blue Team members and system/security engineers who would like to take advantage of the OSSEC integration capabilities with other tools and increase the visibility of their infrastructure behaviour.
I’m using OSSEC to feed an instance of TheHive to investigate security incidents reported by OSSEC. To better categorize the alerts and merge similar events, I needed to add more observables. OSSEC alerts are delivered by email with interesting information for TheHive. This was an interesting use case to play
