Incident response modernization

Integrate NIST SP 800-61r2, ISO/IEC 27035-1:2023, SEC Regulation S-K Item 106, and CISA federal incident playbooks into a single automation-ready response system.^{NIST SP 800-61r2}^{ISO/IEC 27035-1:2023}^{SEC Regulation S-K Item 106}^{CISA Federal Incident Response Playbook}

Anchor lifecycle governance

Adopt lifecycle language that regulators, auditors, and operators share so incident actions remain defensible.

Standardize the four phases. Use NIST SP 800-61r2’s prepare, detect/analysis, contain/eradicate/recover, and post-incident cycle as your canonical taxonomy and align status reports, tickets, and playbooks to those phases.^{NIST SP 800-61r2}
Codify ISO event classes. Mirror ISO/IEC 27035-1:2023 event categories and escalation triggers so SOC analysts know when an event becomes an incident that requires formal evidence capture and leadership notification.^{ISO/IEC 27035-1:2023}
Embed disclosure clocks. Map materiality assessments and the four-business-day Form 8-K disclosure window into containment runbooks for registrants subject to SEC Item 106 so investigation notes, decision logs, and board updates are audit-ready.^{SEC Regulation S-K Item 106}

Connect detection engineering outputs to response playbooks with predefined evidence, communications, and regulatory checkpoints.

Link detections to playbooks. For each MITRE ATT&CK technique in your SIEM/XDR content library, bind the triggering rule to the correct CISA playbook step so automated tickets launch the right containment and eradication actions.^{MITRE ATT&CK}^{CISA Federal Incident Response Playbook}
Pre-stage forensic evidence. Enforce tamper-evident log retention, chain-of-custody fields, and image-capture procedures that match ISO/IEC 27035-1:2023 and NIST SP 800-61r2 guidance before an incident occurs.^{ISO/IEC 27035-1:2023}^{NIST SP 800-61r2}
Automate stakeholder notifications. Parameterize messaging for legal, privacy, customers, and suppliers so communications satisfy SEC Item 106, contractual reporting clauses, and sector rules like DORA Article 19 without manual drafting during crises.^{SEC Regulation S-K Item 106}^{EU DORA Article 19}

Exercise the program on the cadence regulators expect and capture evidence in a reusable format.

Design realistic scenarios. Rehearse ransomware, supplier compromise, cloud credential theft, and operational technology intrusions using ATT&CK and ATT&CK for ICS techniques so playbooks reflect current tradecraft.^{MITRE ATT&CK}^{MITRE ATT&CK for ICS}
Test cross-team communications. Align exercise injects with CISA’s federal playbook communication checkpoints and ISO/IEC 27035-1:2023 roles so legal, communications, and executive teams can practice rapid decision-making.^{CISA Federal Incident Response Playbook}^{ISO/IEC 27035-1:2023}
Capture audit-quality evidence. Store tabletop minutes, metrics (MTTD/MTTR), decision logs, and remediation tickets in a repository that can be shared with regulators or auditors to demonstrate continuous improvement. ^{NIST SP 800-61r2}^{SEC Regulation S-K Item 106}

Define clear interfaces so external partners accelerate containment without introducing new risks.

Set CSIRT service levels. Align managed detection and response contracts with the FIRST CSIRT Services Framework so triage, analysis, and stakeholder coordination expectations are explicit.^{FIRST CSIRT Services Framework v2.1}
Control data handling. Require suppliers to follow CISA playbook evidence-handling steps and NIST SP 800-61r2 retention guidance so legal and privacy obligations are preserved during outsourced investigations.^{CISA Federal Incident Response Playbook}^{NIST SP 800-61r2}
Build feedback loops. Convert after-action items into detection engineering tasks and policy updates tied to MITRE ATT&CK coverage so continuous improvement is measurable. ^{MITRE ATT&CK}
