Defending The SOC, the first stage of CTF International MetaRed '21 concluded with record participation in the exercise organized by the service managed by FCCN, the RCTS CERT.

The 24-hour Defending The SOC event, organized by the computer security incident response service of the FCCN unit of the Foundation for Science and Technology (FCT), RCTS CERT, took place from 10 to 11 August.

The online event was composed of 30 challenges from various categories, and had around 800 entries, which resulted in the formation of 478 teams. Of the 372 that scored, 89% solved at least 3 challenges.

This Capture The Flag is part of the CTF International MetaRed '21 championship, which will have 4 more stages organized by the international MetaRed partners in Argentina, Mexico, Ecuador and Portugal again.

The 30 challenges proposed by RCTS CERT were distributed by the categories of cryptography, forensic analysis, OSINT, networks, reverse engineering, pwn, web and mission. Of these, 9 were designed with a logical sequence, in the mission category, within a framework of an attack on a SOC (Security Operations Centre ) and consequent defensive and offensive reaction.
