Lukáš Šišmiš from CESNET contributed to a significant improvement of the Suricata open-source security tool

Prague, 2 August 2023. Suricata is an open-source network threat detection system that works in both IDS and IPS security modes. It is being developed by an international group of experts under the auspices of the non-profit organisation OISF (Open Information Security Foundation).

A new version of Suricata, which brings several interesting improvements, was released on July 18 this year. The most significant change is the new support for the DPDK interface (Data Plane Development Kit). This important feature was added thanks to the development work of Lukáš Šišmiš from the Administration and Security Tools Department of CESNET. In addition, based on his achievements in DPDK interface support, he became an official member of the Suricata development team.

The DPDK interface represents a key step forward for Suricata, enabling greater performance and efficiency in processing network traffic. “The innovation strengthens the ability of the Suricata system to monitor a large amount of network traffic, which will be appreciated by our users, especially those who are connected to lines with speeds of tens to hundreds of Gbps,” explains Lukáš Šišmiš, who also presented his work on the tool at several professional events, including a webinar organised under the auspices of the OISF.
