NIST SP 800-61 Rev. 3 (Incident Response Recommendations)
The current NIST incident-response guidance, published in April 2025 as a CSF 2.0 Community Profile. It supersedes Rev. 2 and frames incident response across the CSF functions (Govern, Identify, Protect, Detect, Respond and Recover) rather than the older four-phase lifecycle.
MITRE ATT&CK Framework
A comprehensive, living knowledge base of adversary tactics and techniques. In 2026, it is used to map observed attacker behavior during an incident to known threat actor groups and remediation playbooks.
TheHive
StrangeBee's commercial case-management platform for SOC, CSIRT and CERT teams. It covers alert triage, investigation, collaboration and reporting, with MISP and MITRE ATT&CK integration and 300+ connectors. TheHive was open source until 2021, when distribution moved to a commercial model.
Shuffle
An open-source SOAR platform that allows IR teams to automate repetitive tasks (like blocking an IP in a firewall or resetting a password) using a visual workflow builder.
Velociraptor
A state-of-the-art digital forensics and incident response (DFIR) tool. It enables surgical precision when collecting forensic artifacts from thousands of remote endpoints simultaneously.
MISP (Malware Information Sharing Platform)
An open-source platform for sharing, storing, and correlating Indicators of Compromise (IoCs). It allows organizations to share threat data with peers to prevent the spread of a localized attack.
Timesketch
An open-source tool for collaborative forensic timeline analysis. It allows multiple investigators to analyze logs and system artifacts together to reconstruct the sequence of a breach.
CISA Incident Response Playbooks
Highly structured operational procedures for conducting cybersecurity incident and vulnerability response. Essential for organizations aligning with federal compliance standards.
SANS Cybersecurity Posters & Cheat Sheets
SANS's library of printable security posters and cheat sheets, including incident-response references for memory forensics, DDoS response and quick-look intrusion discovery on Windows and Linux.
NIST SP 800-84 (Exercise & Drill Guide, 2006)
Published in 2006 and still current, this guide covers testing IR capabilities through tabletop exercises, functional drills and full-scale simulations. Rehearsing the plan is what keeps a real event from turning into improvisation.
NIST SP 800-184 (Cyber Event Recovery, 2016)
Published in 2016 and still current, this guide focuses on the 'Recover' function: strategies for planning, testing and improving the restoration of data and systems after a destructive cyber event.
DFIR-IRIS
An open-source, collaborative incident-response platform. Cases, timelines, evidence and shared war rooms sit in one workspace, with MISP, VirusTotal and SIEM integrations, and it can be self-hosted on your own infrastructure.
Volatility 3
The reference framework for memory forensics, rewritten for Python 3. It analyses a RAM image for running processes, network connections, injected code and cached credentials, which is often the only evidence left once malware has removed its files. Released under the Volatility Software License.
