πŸ›‘οΈ EDR / MDR / XDR

Detect Fast, Respond Safely, Prove Everything

EDR / MDR / XDR is your stacked strategy for finding real threats quickly, stopping them safely, and shipping audit-ready evidence.
SolveForce designs, deploys, and operates these capabilities so they work togetherβ€”with identity, network, cloud, and data controlsβ€”under a Zero-Trust model.

🎯 What Each Piece Means (Clear and Practical)

  • EDR β€” Endpoint Detection & Response
    Agent on endpoints/servers that collects process, script, file, registry, and network telemetry; raises detections; enables isolate/kill/quarantine and forensic collection.
    β†’ Deep dive: EDR (endpoint-focused page)
  • MDR β€” Managed Detection & Response
    24Γ—7 service operating on top of EDR/XDR + SIEM/SOAR to triage, investigate, and contain incidentsβ€”then report with executive evidence.
    β†’ Details: MDR
  • XDR β€” Extended Detection & Response
    Correlates endpoint + network + identity + email/web + cloud signals, reduces noise, and coordinates response across domains via SOAR.
    β†’ Details: XDR

Quick rule: Start with EDR for host truth, add MDR for 24Γ—7 response, lift to XDR to cut false positives and contain across identity/network/cloud.


🧱 Architecture (Four Layers Working Together)

1) Collect & Normalize – EDR agents, NDR sensors, IdP/SSO logs, email/web gateways, cloud control-plane, app/API logs β†’ normalized schema.
2) Detect & Correlate – rules, sequences, baselines (UEBA), intel β†’ high-confidence alerts (XDR).
3) Decide – risk policy + approvals: contain now, step-up MFA, quarantine, rotate secrets, or escalate.
4) Act & Prove – SOAR runs playbooks (isolate host, block domain/IP, NAC quarantine, SD-WAN pin, ZTNA revoke), then writes back evidence to SIEM and cases.

πŸ” Telemetry We Use (and Why)

  • Endpoints (EDR) β€” process trees, command lines, script telemetry, kernel/file events, persistence; fastest host truth.
  • Network (NDR) β€” east–west + egress (DNS, TLS SNI/JA3, flows/PCAP metadata); finds lateral movement/beacons/exfil where agents can’t run. β†’ NDR
  • Identity β€” IdP sign-ins (SAML/OIDC), MFA outcomes, privilege changes; detects account takeover early. β†’ IAM / SSO / MFA
  • Email/Web β€” phishing/BEC verdicts, sandbox results, SWG/CASB; stops the front-door. β†’ SASE β€’ WAF / Bot Management
  • Cloud/Kubernetes β€” CloudTrail/Activity logs, API abuse, storage/object moves, k8s audit; closes cloud blind spots. β†’ Cloud
  • Data Security β€” DLP events, watermark/read-only actions; proves containment of sensitive data. β†’ DLP

🚨 High-Value Detections (ATT&CK-Aligned)

  • Ransomware Behavior β€” rapid file encryption + shadow-copy tamper + suspicious parent tree β†’ isolate host, kill process, hash block, restore path.
  • C2 + Credential Misuse β€” periodic beacons + Kerberos anomalies/SSO token abuse β†’ isolate, revoke sessions, rotate secrets (PAM). β†’ PAM
  • Lateral Movement β€” SMB enum/RDP valid + new service/SchTasks + admin group add β†’ NAC quarantine, kill process, notify IAM. β†’ NAC
  • Data Exfil β€” big egress to new ASN/cloud bucket + DLP hits + odd time/geo β†’ block egress, lock account, open IR case. β†’ Incident Response
  • BEC (Business Email Compromise) β€” inbox rule + lookalike domain + impossible travel β†’ token revoke, tenant purge, finance alert.

🧰 Orchestrated Response (Safe by Design)

  • Endpoints β€” isolate host; kill/quarantine file/process; take triage bundle. β†’ EDR
  • Network β€” FW/WAF rule push, NAC quarantine, SD-WAN path pin/blackhole, Anycast withdraw. β†’ NAC β€’ SD-WAN β€’ WAF / Bot Management
  • Identity β€” session revoke, step-up MFA, account lock, PAM rotate. β†’ IAM / SSO / MFA β€’ PAM
  • Cloud/SaaS β€” disable keys, freeze buckets, snapshot disks, CASB session control. β†’ Cloud β€’ SASE
  • Data β€” quarantine object, watermark, route to tokenization. β†’ DLP

Safety rails: human approvals for destructive steps, simulation/dry-run, blast-radius caps, automatic rollback/circuit-breaker, change IDs via ITSM.

Dashboards live in SIEM/SOAR and the NOC; monthly reports track MTTD/MTTR, precision/recall, auto-contain %, and noise reduction.

πŸ§ͺ Tuning & Noise Reduction (Weekly Loop)

1) Review false positives/negatives; adjust sequences, intel, thresholds; retire noisy rules.
2) Promote successful hunts to rules; remove rules that never fire.
3) Validate ingestion lag and parser health (schema drift = bad detections).
4) AIOps to dedupe flaps and correlate multi-signal incidents. β†’ NOC Services


☁️ Cloud & Hybrid Patterns (Real-World Starting Points)

  • EDR β†’ XDR Start β€” keep your EDR; add identity + NDR + email + cloud to raise fidelity quickly. β†’ NDR
  • Colo Hub + On-Ramps β€” put detection close to Direct Connect/ExpressRoute/Interconnect; deterministic paths for crown-jewel apps. β†’ Direct Connect β€’ Colocation
  • Remote/OT/IoT β€” where agents can’t run, rely on NDR, NAC, and ZTNA to detect/contain. β†’ NAC β€’ ZTNA

πŸ”’ Zero-Trust Interlock (Identity β†’ Device β†’ Network β†’ Data)

  • Identity β€” SSO/MFA, adaptive risk, step-up for admin actions. β†’ IAM / SSO / MFA
  • Device β€” UEM posture gates access; non-compliant devices quarantined. β†’ MDM / UEM
  • Network β€” micro-isolation with NAC/SD-WAN/SASE; Anycast withdraw for sick POPs. β†’ SASE
  • Data β€” DLP rules, tokenization, and watermarks enforced inline. β†’ DLP

🧾 Reporting, Evidence & Compliance

  • Cases β€” alert β†’ triage β†’ actions β†’ closure with artifacts (PCAPs/hashes/logs), owners, approvals, RCAs.
  • Executive IR β€” scope, dwell time, impacted assets, controls added; share with audit.
  • Mappings β€” PCI DSS, HIPAA, ISO 27001, NIST 800-53/171, CMMC; exportable evidence packs.
    All events flow to SIEM; actions executed via SOAR with immutability options for retention. β†’ SIEM / SOAR

🧰 Implementation Blueprint (No-Surprise Rollout)

  1. Source inventory β€” EDR, NDR, IdP, email/web, cloud, FW/WAF, DLP, ticketing.
  2. Schemas & parsers β€” normalized fields (host/user/src/dst/action/severity/labels).
  3. Priority use cases β€” ransomware, ATO/BEC, exfil, lateral movement; set precision/recall targets.
  4. Playbooks & approvals β€” isolate/kill/block/revoke/rotate/snapshot; blast-radius caps; rollback.
  5. SLOs & dashboards β€” MTTD/MTTR, precision/recall, coverage %, ingestion lag.
  6. Drills β€” quarantine VLAN, token revoke, WAF virtual patch, sinkhole; record RCAs. β†’ Tabletop Exercises
  7. Operate & tune β€” weekly loop; publish wins and next steps.

πŸ’΅ Commercials (What Drives Cost)

  • Seat/endpoint count (workstations, servers, VDI).
  • Telemetry scope (EDR-only vs. XDR cross-domain).
  • Retention (hot/warm/cold days) and log egress.
  • SOAR playbook volume and approval gates.
  • 24Γ—7 MDR vs. business hours, and reporting cadence.

We model TCO vs. in-house best-effortβ€”showing improvements in MTTD/MTTR, noise reduction, and audit readiness.
