Endpoint Detection & Response (with MDR & XDR Options)
Endpoint Detection & Response (EDR) continuously monitors laptops, desktops, servers, and VDI to detect, investigate, and contain threats in real time. SolveForce designs EDR as part of a Zero-Trust stack—integrated with identity, device posture, network controls, and orchestration—so incidents are found fast, stopped safely, and documented for audits.
Where EDR fits in the SolveForce model:
🔒 Security (Semantics) → Cybersecurity • 👤 Identity → IAM / SSO / MFA
📱 Device Trust → MDM / UEM • 🌐 Access → ZTNA / SASE
📊 Analytics & Automation → SIEM / SOAR • 🖧 East-West → NDR
🔄 Ops → Patch Management • NOC Services
🎯 Outcomes (What a strong EDR program delivers)
- Rapid detection of malware, fileless attacks, and suspicious behaviors.
- Containment in minutes (isolate host, kill process, block hash/domain).
- End-to-end evidence (timeline, artifacts, and actions) for IR and audits.
- Lower MTTR via automated SOAR playbooks and clear runbooks.
- Zero-Trust alignment with identity, device posture, and network policy.
🧭 EDR vs. MDR vs. XDR (Spelled out)
| Term | What it means | When to choose |
|---|---|---|
| EDR — Endpoint Detection & Response | Agent on endpoints collects telemetry (processes, modules, registry, network), detects threats, and enables remote response. | You have a security team running detections and response. |
| MDR — Managed Detection & Response | A provider operates 24×7 monitoring, triage, and response on top of your EDR. | You need round-the-clock eyes and expertise. |
| XDR — Extended Detection & Response | Correlates endpoint with email, identity, network, cloud telemetry for higher-fidelity detections. | You want fewer false positives and cross-domain visibility. |
SolveForce can implement EDR-only, EDR + MDR, or XDR depending on your team and scope.
🧱 Core EDR Capabilities
- Behavior analytics — process trees, script/PowerShell logging, LOLBins detection, in-memory indicators.
- Ransomware prevention — suspicious encryption patterns, shadow-copy tamper alerts, rapid isolate.
- Threat intel & hash control — blocklists/allowlists, suspicious publisher detection.
- Response actions — isolate endpoint, kill/quarantine, registry/file rollback (where supported), collect triage package.
- Hunt & query — fleet-wide queries (e.g., “who has
xyz.dllloaded?”), scheduled hunts with saved results. - Forensics — timeline, artifacts, persistence keys, network beacons, exfil domains.
🔒 Zero-Trust Interlock (Identity → Device → Network → Data)
- Identity: require SSO/MFA for console access; role-based least privilege. → IAM / SSO / MFA
- Device: MDM/UEM posture gates access (encryption on, EDR healthy, OS version). Non-compliant → quarantine. → MDM / UEM
- Network: isolate host, apply microseg rules, or route through ZTNA/SASE for inspection. → ZTNA • SASE
- Data: invoke DLP for suspected exfil; watermark or block uploads. → DLP
🧩 Telemetry & Detection Sources
- Process & script telemetry (command lines, parent/child relations, AMSI where supported).
- Kernel/driver events (file, registry, handle operations).
- Network events (destinations, DNS, TLS SNI, certificate metadata).
- Persistence & autoruns (services, tasks, WMI, Run keys).
- User/identity signals (logon type, token operations, privilege escalations).
- Threat intel (hash/domain/IP feeds; sandbox verdicts).
Correlate with NDR (Network Detection & Response) for east-west visibility and exfil. → NDR
🚨 Response Playbooks (Concrete, repeatable)
Sev-1: Active ransomware behavior
1) Isolate host from network.
2) Kill offending process; revoke tokens; disable scheduled tasks.
3) Block hash/domain; snapshot/dump forensics.
4) Halt propagation via NAC/SD-WAN policy; force reauth via IAM. → NAC • SD-WAN
5) Recover files (restore points/immutable backup). → Backup Immutability
Sev-2: Suspected credential theft (infostealer/DCOM abuse)
1) Expire sessions; force MFA for impacted identities. → IAM / SSO / MFA
2) Rotate secrets (PAM for privileged). → PAM
3) Hunt for lateral movement; tighten ZTNA groups. → ZTNA
Sev-3: PUA/Adware
1) Remove; 2) Add to blocklist; 3) Ticket for user coaching; 4) Close.
All playbooks run via SOAR (Security Orchestration, Automation & Response) to cut MTTR. → SIEM / SOAR
🧰 Deployment Patterns (OS & fleet realities)
- Windows — kernel/ETW visibility; AMSI; script block logging.
- macOS — system extensions; full disk access consent; notarized builds.
- Linux — eBPF/auditd/Kprobe visibility; container/daemon sets for servers.
- VDI/DAAS — persistent vs non-persistent images; update via golden image + post-login health.
- Servers — exclusion tuning for DB/backup paths; low-impact modes for latency-sensitive hosts.
🧪 Tuning & Noise Reduction (Keep signal high)
- Golden exclusions for backup paths, hypervisors, DB stores—documented and reviewed.
- Behavior-first rules (avoid pure hash firehose); use ATT&CK-mapped detections.
- AIOps in the NOC to dedupe flaps and correlate multi-signal incidents. → NOC Services
- Hunt calendar (weekly scheduled queries); retire detections that never fire or always false-positive.
📐 SLO Guardrails (Experience & speed you can prove)
| Metric | Target (Recommended) | Notes |
|---|---|---|
| Mean Time To Detect (MTTD) | ≤ 5 minutes for Sev-1 | With high-fidelity rules/SOAR |
| Mean Time To Contain (MTTC) | ≤ 15 minutes Sev-1 | Auto-isolation + kill + block |
| Agent coverage | ≥ 98–99% endpoints | Exceptions documented & risked |
| False Positive Rate | ≤ 5% of total alerts | Weekly tuning loop |
| CPU/Memory overhead | ≤ 3–8% / ≤ 300–500 MB | Per vendor/feature set |
| Evidence completeness | 100% of Sev-1/2 with timeline & artifacts | IR/audit-ready |
Dashboards live in SIEM, EDR console, and NOC views; weekly reports summarize trends and actions.
🔒 Compliance Mapping (examples)
- PCI DSS — malware detection, file-integrity monitoring, least privilege, log retention.
- HIPAA — audit controls, integrity, person/entity authentication.
- ISO 27001 — A.8, A.12 (ops security), A.16 (incident mgmt).
- NIST 800-53/171 — SI/CM/IR families; endpoint content and incident handling.
- CMMC — detection & incident response maturity.
Evidence streams to SIEM/SOAR with incident IDs, actions, and approvals.
✅ Pre-Engagement Checklist
- Fleet inventory — OS mix, VDI, server roles, privileged endpoints.
- Use-case priorities — ransomware stop, lateral-movement detection, PII/PHI protection.
- Integrations — IdP/SSO, MDM/UEM, NAC/SD-WAN, SIEM/SOAR, ticketing.
- Playbooks — isolate, kill, block, secrets rotate, restore, reauth, notify.
- Exclusions — DB/backup/AV paths; high-IO workloads.
- SLOs — MTTD/MTTC, coverage %, FP rate, performance caps, reporting cadence.
