🚨 Incident Response

Detect, Contain, Eradicate, Recover—With Evidence

Incident Response (IR) is how you detect, triage, contain, eradicate, and recover from security events—quickly and with audit-grade evidence.
SolveForce implements IR as a system: playbooks in SOAR, signal from SIEM, containment via EDR/NDR/SD-WAN/Identity, and recovery powered by immutable backups and DRaaS—all measured by RPO/RTO and MTTx SLOs.

Connected stack:
📊 SIEM / SOAR → /siem-soar • 🛡️ EDR/MDR/XDR → /mdr-xdr • 🖧 NDR → /ndr
🔑 IAM / SSO / MFA → /iam • 🧰 PAM → /pam • 🔐 DLP → /dlp
💾 Cloud Backup → /cloud-backup • 🔒 Backup Immutability → /backup-immutability • ☁️ DRaaS → /draas

🎯 Outcomes (Why SolveForce IR)

  • MTTD/MTTR down— detect and contain in minutes, not hours.
  • Least-blast-radius— identity-, device-, and network-level containment with rollback.
  • Clean recovery— restore from immutable backups and orchestrated DR.
  • Complete evidence— timelines, artifacts, approvals; exportable to auditors.
  • Operational calm— rehearsed playbooks, clear comms, and decision trees.

🧭 Scope (What we handle)

  • Endpoints/Servers/VDI — malware, ransomware, LOLBins, persistence, lateral movement. → /mdr-xdr
  • Network/East-West — C2 beacons, DNS tunneling, exfil, rogue services. → /ndr
  • Identity/Access — account takeover (ATO), token/session theft, privilege abuse. → /iam • /pam
  • Cloud/SaaS — misconfig, API abuse, key leaks, BEC (Business Email Compromise).
  • Apps/Web/API — OWASP Top-10, bot/card testing, L7 DDoS. → /waf • /ddos

🧱 IR Framework (Spelled out)

1) Prepare — playbooks, roles, SLAs, evidence stores, immutable backups, DR runbooks.
2) Detect — high-fidelity rules in SIEM, signals from EDR/NDR/Cloud/Email. → /siem-soar
3) Triage — severity, scope, crown-jewel impact, decision to contain.
4) Contain — EDR isolate, NAC quarantine, SD-WAN path pin/blackhole, ZTNA revoke, WAF/Flowspec blocks. → /nac • /sd-wan • /ztna
5) Eradicate — kill processes, remove persistence, rotate secrets/keys, patch. → /secrets-management • /key-management
6) Recover — restore from immutable backups, validate clean-point, fail back via DRaaS. → /cloud-backup • /backup-immutability • /draas
7) Lessons Learned — RCA, control gaps, policy/module updates, executive report.

Automation: SOAR orchestrates actions with approvals, blast-radius caps, and auto-rollback. → /siem-soar

🚨 Priority Playbooks (ATT&CK-aligned, audit-ready)

1) Ransomware Behavior (Sev-1)

  • Detectrapid encrypt/rename + shadow-copy tamper + suspicious parent tree.
  • ContainEDR isolate host → NAC quarantine VLAN → SD-WAN pin → revoke sessions.
  • Eradicatekill encryptor, remove persistence, rotate secrets/keys.

📐 SLO Guardrails (Commit to numbers)

SLO / KPITarget (Recommended)
MTTD (Sev-1)≤ 5–10 min (SIEM correlation)
Triage start (Sev-1)≤ 10 min from alert
Containment (Sev-1)≤ 15–30 min (EDR/NAC/SD-WAN/Cloud)
Forensic acquisition start≤ 60 min (where applicable)
Clean-point identification (ransomware)≤ 2–4 h with job logs/checksums
RTO (Tier-1 apps)≤ 5–60 min via DRaaS runbooks
Evidence completeness (Sev-1/2 cases)= 100% (timeline, artifacts, approvals)
Executive comms published≤ 24 h initial; updates as agreed

SLO breaches trigger SOAR escalations and management notifications. → /siem-soar

🔒 Zero-Trust Containment (Practical controls)

  • Endpoints: EDR isolate, kill process, quarantine file, rollback (where supported). → /mdr-xdr
  • Network: NAC quarantine, SD-WAN pin/blackhole, WAF/Flowspec blocks. → /nac • /sd-wan • /waf
  • Identity: revoke sessions, step-up MFA, lock/rotate privileged access (PAM). → /iam • /pam
  • Data: DLP quarantine, watermark/read-only, tokenization routes. → /dlp
  • Keys/Secrets: disable/rotate keys, re-issue short-lived creds from vault. → /key-management • /secrets-management

📊 Evidence & Communications

  • Case timelines— alert → triage → actions → recovery; hash all artifacts.
  • Artifacts— PCAPs, memory/drive images (where applicable), logs, configs, screenshots.
  • Approvals— who authorized isolate/lock/rotate/restore; change IDs.
  • Reports— executive summary, scope, dwell time, impact, controls added, next steps.
  • Stakeholders— execs, legal, HR, PR, regulators/customers (as required).
    All exported to SIEM with WORM options; SOAR holds action history. → /siem-soar

🧰 Readiness Pack (what we put in place)

  • Playbook library— ransomware, ATO/BEC, exfil, cloud key leak, DDoS, insider, supply chain.
  • Runbooks— DR cutover, mailbox purge, token revoke, RTBH/Flowspec, cache purge, Anycast withdraw.
  • Access matrix— who can isolate hosts, lock users, rotate keys, fail over, talk to press.
  • Clean-point catalog— pre-validated restore sets for crown-jewel apps.
  • Drills— tabletop & live; lessons learned feed policy & IaC. → /infrastructure-as-code

📜 Compliance Mapping (Examples)

Key terms in plain language

Open a term for a concise explanation of language used on this page.

SD-WAN

Software-defined wide area networking. It manages multiple connections and chooses paths based on application needs, performance, and policy to improve resilience and control.

Software as a Service (SaaS)

Software accessed as an online service instead of being installed and maintained entirely on the customer’s own computers or servers.

Disaster Recovery (DRaaS)

A plan and service for restoring applications, data, and operations after an outage or disruption. DRaaS provides recovery infrastructure through a managed cloud service.

Cybersecurity

The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.

Zero Trust

A security model that does not automatically trust a user or device because of its location. Access is continuously verified and limited to what is necessary.

SASE

Secure Access Service Edge combines networking and security capabilities in a cloud-delivered architecture so users and locations can receive consistent policy wherever they connect.

Identity and Access Management (IAM)

The systems and policies that determine who a user is, what resources they may access, and how that access is authenticated and reviewed.

Multi-Factor Authentication (MFA)

A login control requiring more than one form of verification, such as a password plus an authenticator app, security key, or biometric factor.
