CERT Société Générale's incident response cheat sheets

Incident Response Methodologies (IRM) is CERT Société Générale’s free collection of incident-handling cheat sheets, one PDF per incident type, from worm infections and DDoS to phishing and ransomware, in English with a French translation by CERT aDvens. This 2022 edition, published at the end of November with CERT aDvens as contributor, succeeds the earlier IRM set the CERT put on GitHub in 2016. Every sheet follows the same six steps (preparation, identification, containment, remediation, recovery and lessons learned), which the IRMs attribute to NIST’s Computer Security Incident Handling Guide. Pro tip: print the one you need before the incident, not during it.
