πŸ›‘οΈ Endpoint Detection & Response (EDR)

(Real-Time Threat Stopper, Audit-Ready)

Endpoint Detection & Response (EDR) gives continuous visibility on laptops, desktops, servers, and VDI, detects malicious behavior in real time, and enables safe remote response (isolate host, kill process, quarantine file, collect forensics). SolveForce designs EDR to fit a Zero-Trust stackβ€”aligned with identity, device posture, network controls, and automated responseβ€”so incidents are found fast, stopped safely, and proven with evidence.

Where EDR sits in your system:

🎯 Outcomes (What a strong EDR program delivers)

  • Rapid detection of malware, fileless attacks, living-off-the-land (LOLBins), and risky behaviors.
  • Fast containment β€” isolate host in minutes, kill processes, block hashes/domains, roll back where supported.
  • Complete evidence β€” timelines, artifacts (hashes, PCAPs/triage bundles), approvals; audit-ready.
  • Lower MTTR β€” automated SOAR playbooks and tested runbooks cut response time. β†’ SIEM / SOAR
  • Zero-Trust alignment β€” access depends on healthy EDR posture; non-compliant devices are quarantined. β†’ ZTNA β€’ SASE

🧱 What EDR Watches (Telemetry Sources)

  • Process & script events (command lines, parent/child chains, PowerShell/AMSI, bash/audit).
  • Kernel & file activity (module loads, registry/autoruns, driver hooks, file rename/encrypt patterns).
  • Network from the endpoint (DNS, destinations, TLS SNI, suspicious beacons).
  • Persistence (services, tasks, WMI, run keys, LaunchAgents/Daemons).
  • Identity context on the endpoint (logon type, token manipulations, elevation).
  • Threat intel (hash/domain/IP, reputation, sandbox verdicts) with continuous updates.

Correlate with NDR for east–west lateral movement and exfil trails. β†’ NDR


πŸ” High-Value Detections (ATT&CK-Aligned)

  • Ransomware behaviors β€” rapid encrypt/rename, shadow-copy tamper, suspicious parent trees.
  • Credential access β€” LSASS memory access, Kerberos ticket abuse, token theft.
  • Persistence & privilege β€” new services/SchTasks, unsigned drivers, LOLBins used abnormally.
  • C2 & beacons β€” low-and-slow periodic callbacks, JA3/JA3S anomalies, DNS tunneling artifacts.
  • Lateral movement β€” abnormal SMB/RDP/WMI/WinRM patterns; sudden admin group adds.
  • Exfiltration β€” large egress from endpoints to new ASNs or cloud buckets.

🚨 Response Actions (Safe, Remote, Reversible)

  • Host isolate (keep SIEM/EDR channels alive).
  • Kill process / quarantine file with hash/domain blocklists.
  • Collect triage bundle (memory/process/file artifacts) for IR.
  • Rollback (where supported) of ransomware activity.
  • Trigger compensating controls β€” NAC quarantine/VLAN, ZTNA revoke, SD-WAN path pin.

All actions run under SOAR with approvals, blast-radius caps, and automatic rollback. β†’ SIEM / SOAR


🧭 Platform & Fleet Realities (How We Deploy)

  • Windows β€” deep ETW/AMSI visibility; script block logging; driver tamper protections.
  • macOS β€” system extensions; notarized agents; Full Disk Access consent flows.
  • Linux β€” eBPF/auditd/kprobe; containers/DAAS via daemonset or golden image.
  • VDI/DAAS β€” persistent vs non-persistent images; post-login health checks.
  • Servers β€” tuned exclusions for DB/backup paths; low-impact modes for latency-sensitive systems.

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

  • Identity β€” SSO/MFA for console & approvals; least-privilege roles. β†’ IAM / SSO / MFA
  • Device β€” EDR posture feeds conditional access; non-compliant β†’ quarantine or ZTNA deny. β†’ ZTNA
  • Network β€” micro-isolation with NAC/SASE/SD-WAN; Anycast withdraw if a POP is β€œsick.” β†’ SASE
  • Data β€” DLP protect/contain (redact/quarantine/watermark) on suspected exfil. β†’ DLP

πŸ”§ Tuning & Noise Reduction (Signal > Noise)

  • Behavior-first rules (ATT&CK) over hash firehoses.
  • Golden exclusions for backup/DB/hypervisor paths (documented; reviewed quarterly).
  • Hunt calendar (weekly queries: persistence sets, anomalous JA3s, LSASS access).
  • AIOps in the NOC to dedupe alert flaps and correlate multi-signal incidents. β†’ NOC Services

🧾 Compliance Mapping (Examples)

  • PCI DSS β€” malware detection, file-integrity/hardening evidence.
  • HIPAA β€” audit controls, person/entity authentication, integrity.
  • ISO 27001 β€” A.12 (ops security), A.16 (incident mgmt).
  • NIST 800-53/171 β€” SI, IR, CM families; endpoint content + incident handling.
  • CMMC β€” detection/response maturity with evidence exports.
