description

Guides information security engineering—implementing and operating security controls, identity and access systems, encryption and secrets management, security tool integrations (SIEM, EDR, SOAR), cloud guardrails, hardening baselines, and remediation engineering for vulnerabilities. Use when building SSO/RBAC/PAM patterns, configuring KMS or certificate lifecycle, deploying WAF/DLP or EDR connectors, writing security-as-code policies (OPA, SCPs, CIS benchmarks), integrating logging to SIEM, automating security workflows, or validating control fixes—not for SOC triage (soc-analyst), pentesting (penetration-tester, network-pentester, web-pentester), red team (red-team-specialist), CI gates only (devsecops), platform provisioning without security ownership (infrastructure-engineer), CISO/exec program (chief-information-security-officer), security program strategy (cybersecurity), GRC program and audit prep (compliance-specialist), or product tenancy isolation (product-infrastructure-security-engineer).

Information Security Engineer

When to Use

• Implement and operate security controls such as SSO, RBAC, PAM, KMS, certificate management, WAF, DLP, EDR, or SIEM integrations
• Translate security architecture, audit findings, or policies into deployable guardrails and validation checks
• Build identity, encryption, secrets, logging, or security automation workflows
• Harden cloud accounts, endpoints, SaaS apps, and baseline configurations with security ownership
• Validate remediation for vulnerabilities and control gaps

When NOT to Use

• Board briefings, risk appetite, security budget, crisis exec comms → chief-information-security-officer
• Define security strategy or enterprise security program → cybersecurity
• GRC program, framework scope, audit prep, questionnaires → compliance-specialist
• Triage alerts, SOC playbooks, or shift ops → soc-analyst
• Deep investigation, hunts, or detection authoring → defensive-security-analyst
• Execute authorized pentests or exploit validation → penetration-tester, network-pentester, web-pentester
• Plan adversary simulation or purple-team campaigns → red-team-specialist
• Add CI/CD security gates, SBOMs, or artifact signing only → devsecops
• Design tenant isolation and product data-plane boundaries → product-infrastructure-security-engineer
• Cloud org guardrails, CSPM, multi-account IAM/network security → cloud-security-engineer
• IAM program design, access reviews, federation, PAM, SoD (without tool deploy) → iam-specialist

Core Workflows

1. Control implementation

Translate architecture or policy into deployable controls:

1. Confirm requirement source (policy, threat model, audit finding)
2. Choose control type: preventive, detective, corrective
3. Implement in IaC or managed config (versioned, reviewed)
4. Define validation test (automated where possible)
5. Document owner, exception process, and review cadence

See references/control_hardening.md for baselines and guardrail patterns.

2. Identity and access engineering

human identity (SSO/MFA) → RBAC/ABAC → service identities → privileged access (PAM) → periodic review

• Federate apps to IdP; enforce MFA and conditional access
• Least-privilege IAM roles; no long-lived access keys on humans
• Break-glass accounts monitored and rare
• Quarterly access reviews with evidence export

See references/identity_access_engineering.md for patterns and anti-patterns.

3. Encryption and secrets

Layer	Typical implementation
Data at rest	KMS, volume encryption, TDE
Data in transit	TLS 1.2+, cert automation (ACME/internal CA)
Application secrets	Vault, cloud secret manager, rotation
Keys	CMK policies, separation of duties, audit logs

Never commit secrets; scan repos; rotate on incident.

See references/encryption_secrets.md for key lifecycle and TLS checklist.

4. Security tooling integration

Integration checklist:

1. Log/agent deployment coverage target (e.g., 95% endpoints)
2. Parser/normalization and field mapping
3. Correlation rules owned by detection team
4. SOAR playbooks for approved auto-actions only
5. Health monitoring on collectors and API quotas

See references/security_tooling.md for SIEM/EDR/SOAR integration notes.

5. Vulnerability remediation engineering

Work with app and platform teams:

1. Ingest findings (scanner, pentest, bug bounty)
2. Prioritize: exploitability × asset criticality × exposure
3. Assign owner and SLA by severity
4. Implement or review fix (patch, config, code)
5. Validate with rescan or analyst sign-off
6. Track exceptions with expiry

See references/vulnerability_remediation.md for SLA table and validation steps.

6. Change and release for security systems

Security changes are production changes:

• Peer review on IaC and policy PRs
• Staged rollout (dev → stage → prod)
• Rollback plan for IdP, WAF, or SIEM parser changes
• Post-change validation within 24h
