Access Control Policy

Zero-Trust Architecture

Zero-trust principles: Never trust, always verify: no implicit trust (network location irrelevant, inside network = outside network, no trusted zone concept), continuous verification (every access request challenged, identity verified, device posture checked, context evaluated), least privilege (minimum necessary access, just-in-time when possible, time-limited elevated access, revoke when not needed). Assume breach: defense in depth (multiple security layers, network segmentation, application-level access controls, data encryption), lateral movement prevention (micro-segmentation, east-west traffic inspection, RBAC strictly enforced, monitor internal connections), rapid detection and response (SIEM correlation, behavioral analytics, automated containment, incident response playbooks). Verify explicitly: multi-factor authentication (something you know - password, something you have - phone/token, something you are - biometric, all authentications), contextual access (device health, location, time of day, risk score, step-up authentication for risky contexts), identity-centric (user identity primary perimeter, device identity secondary, workload identity for services, certificate-based where appropriate). Code Ninety zero-trust implementation roadmap: Phase 1 (2021-2022): MFA mandatory (100% adoption achieved Q4 2021), identity foundation (Google Workspace SSO, SAML federation, centralized directory), network segmentation (VPC isolation, security groups, VLANs). Phase 2 (2023): privileged access management (PAM pilot, break-glass procedures, session recording implemented), UEBA deployment (Splunk UEBA, behavioral baselines, risk scoring, anomaly alerts), device posture (MDM enrollment, encryption verification, compliance checks, conditional access). Phase 3 (2024): micro-segmentation (application-level firewall rules, service mesh evaluation Istio, API gateway enforcement Kong), continuous verification (risk-based authentication, step-up MFA, session re-authentication, context-aware policies). Phase 4 (2025 planned): software-defined perimeter (replace VPN with identity-aware proxy, Google BeyondCorp model, Cloudflare Access evaluation), workload identity (service accounts certificate-based auth, SPIFFE/SPIRE, mutual TLS mTLS, eliminate long-lived credentials). Maturity assessment: Forrester Zero Trust Model alignment (2024 self-assessment level 3 - defined and repeatable, target 2026 level 4 - managed and measurable), NIST SP 800-207 (Zero Trust Architecture, core principles implemented, advanced deployment underway, roadmap to maturity).

Identity and access management (IAM) framework: Identity lifecycle management: provisioning (new hire onboarding, HR system trigger BambooHR, Google Workspace account auto-created via API, access based on role template, manager approval workflow), changes (role change, transfer, promotion triggers access review, update role assignments, audit trail documented, 48-hour SLA for access changes), deprovisioning (termination/resignation, immediate account disable, password changed, access revoked all systems, email forwarded 30 days, laptop returned and wiped, exit interview security checklist). Account types: user accounts (employees 120, contractors 18, unique username firstname.lastname@codeninety.com, personalized, no shared accounts), service accounts (applications 47, APIs, automation, non-human, certificate-based or API key, rotation policy 90 days, minimal permissions), privileged accounts (admins 8, separate from user account, username-admin, MFA mandatory, session recording, emergency break-glass accounts sealed). Single Sign-On (SSO): Google Workspace IdP (identity provider, SAML 2.0, OAuth 2.0, centralized authentication, MFA enforced at IdP level), federated applications (GitHub Enterprise, AWS via IAM federation, Slack, Jira, Confluence, 18 apps integrated 2024, goal 25 by 2025), benefits (single password, reduced password fatigue, centralized access control, easier audit, faster onboarding/offboarding, MFA once per session). Directory services: Google Workspace directory (primary directory, user attributes, group memberships, organizational units, API for automation), LDAP integration (legacy systems, read-only LDAP interface, Google Cloud Directory Sync GCDS, sync frequency hourly), group management (security groups for access control, distribution groups for email, dynamic groups based on attributes, nested groups for complex permissions). Federation and trust: external IdPs (client SSO for client-side app access, SAML trust, certificate exchange, metadata updates quarterly), social login (prohibited for business applications, allowed for marketing/community, OAuth 2.0, minimal permissions requested). Identity proofing: identity verification (government ID for employees, HR verification, in-person interview, background check for Confidential+ access), account recovery (security questions, backup MFA method, help desk verification with manager approval, no email-only password reset).

Authentication standards: Password policy: complexity requirements (12 characters minimum, uppercase + lowercase + number + symbol, no dictionary words, not based on username/company name, no keyboard patterns qwerty/12345), rotation (90-day expiry, 24 password history no reuse, new employees set password on first login, service accounts exempt if certificate/key-based), storage (bcrypt hashing salt + hash, never plaintext, no reversible encryption, no transmission in clear, database encrypted at rest), compromised passwords (check against Have I Been Pwned, block commonly breached passwords, alert user if credential stuffing detected, force reset). Multi-factor authentication (MFA): mandatory MFA (100% employees since Q4 2021, 100% privileged access, 100% VPN, 100% production systems, 100% AWS console, no exceptions policy), MFA methods (authenticator apps preferred - Google Authenticator/Microsoft Authenticator/Authy, hardware tokens YubiKey for admins 8 purchased, SMS backup discouraged - SIM swap risk, push notifications Duo for VPN), enrollment (mandatory within 7 days of hire, help desk assistance, backup codes generated and secured, device registration), enforcement (account locked if MFA not enrolled after 7 days, no access until compliant, manager notified, HR escalation if persistent non-compliance). Step-up authentication: high-risk actions (AWS root account access, production database access, financial transactions >$10K, MFA re-prompt required), contextual triggers (new device, new location, unusual time, risk score threshold, additional verification), passwordless future (FIDO2 evaluation, WebAuthn, biometric, eliminate passwords long-term, 2025 pilot planned). Session management: session timeout (30 minutes idle for Confidential data access, 4 hours for general systems, re-authenticate after timeout, configurable per application), session security (secure cookies HttpOnly + Secure + SameSite, CSRF tokens, session fixation prevention - regenerate on login, concurrent session limits 3 per user), remember me (optional for low-security apps, encrypted token, 30-day max, revocable, not allowed for production/Confidential). Certificate-based authentication: use cases (service accounts, API authentication, VPN for high-security users, workload identity future), implementation (X.509 certificates, internal CA, 1-year validity, automatic renewal, revocation checking OCSP), mutual TLS (server + client certificates, API security, zero-trust workload identity, pilot with microservices 2025).

Role-Based Access Control (RBAC)

RBAC model and role definitions: Role hierarchy: 42 defined roles (organized by department and function, documented in IAM policy, approved by Security Steering Committee, annual review and update). Engineering roles: Developer (source code read/write on assigned projects, dev environment full access, staging read-only, production no access, code review submit, testing, 65 users), Senior Developer (all Developer permissions, production read-only logs/metrics, deployment approval authority, code review approve, architecture input, mentor juniors, 18 users), Tech Lead (all Senior Developer, production read-write with approval workflow, infrastructure changes with DevOps, security review participation, hiring input, 8 users), Engineering Manager (all Tech Lead, team access management approve/revoke, budget visibility, performance management, strategic planning, 4 users). DevOps/Infrastructure roles: DevOps Engineer (infrastructure access AWS/GCP, production deployment, CI/CD pipeline management, monitoring configuration, backup/restore, 6 users), Senior DevOps (all DevOps, architecture decisions, disaster recovery, security configuration, on-call escalation, 2 users), Infrastructure Admin (privileged access, root/admin on systems, emergency access, rare use break-glass, 3 users). Security roles: Security Analyst (SIEM access, log analysis, alert triage, incident investigation, vulnerability scanning, 3 users), Security Engineer (all Analyst, security tool administration, policy implementation, penetration testing coordination, 2 users), CISO (all security access, policy approval, incident commander, regulatory liaison, board reporting, 1 user). Business roles: Client Success (CRM access, client data read, project visibility, support ticket system, 8 users), Sales (CRM write, proposal tools, pricing access read-only, demo environments, 6 users), Finance (accounting software, payroll, budget access, procurement approvals, 4 users), HR (HRIS BambooHR, employee records, recruitment, performance management, 3 users), Management (cross-functional visibility, budget access, strategic planning tools, approval authority, 5 users including MD). Role assignment: job function (access based on job requirements, documented in job description, HR provides role during onboarding, manager confirms), principle of least privilege (minimum access to perform job, no excess permissions, default deny then grant needed, justify each permission), temporary roles (project-based access time-limited, contractor access revoked on contract end, secondment access during assignment period, automatic expiration). Role inheritance: role hierarchy (Manager inherits Senior, Senior inherits Developer, eliminates duplication, simplifies management), exceptions (document when inheritance broken, approval required, quarterly review of exceptions, remediate if no longer needed).

Permissions and authorization model: Permission structure: resources (AWS accounts, databases, code repositories, applications, file shares, 250+ resources cataloged), actions (read, write, execute, delete, admin, approve, deploy, granular per resource), conditions (IP restrictions, time-based, MFA required, approval workflows, device compliance). Authorization enforcement: application-level (RBAC enforced in application code, middleware authorization checks, API gateway policies Kong, deny by default), infrastructure-level (AWS IAM policies, security groups, database grants, file system ACLs, network segmentation), centralized policy (Google Workspace admin, AWS Organizations SCPs, policy as code Terraform, version controlled Git). Least privilege implementation: need-to-know (access only to required data, department boundaries, project-based access, client data segregation), minimal permissions (read-only default, write only if needed, admin rarely, execute for service accounts), time-limited (elevated access temporary, automatic expiration, re-request if needed, audit extended access). Separation of duties: financial controls (purchase order + approval different person, payment initiation + approval, dual control >$10K threshold), deployment (developer submits, senior approves, DevOps deploys, no single person all steps), security (developers don't admin, admins don't develop, independent security team, audit function separate). Just-in-time (JIT) access: temporary elevation (request privileged access, manager + security approval, time-limited 4 hours typical, auto-revoke when expires), break-glass (sealed accounts for emergency, password in envelope, change password after use, investigate all uses), use cases (production troubleshooting, emergency patches, incident response, disaster recovery). Conditional access: device compliance (MDM enrolled, encryption verified, OS patched, antivirus current, deny if non-compliant), location-based (Pakistan IPs normal, international travel requires VPN, suspicious location triggers alert, geographic impossible travel detection), risk-based (low risk normal access, medium risk MFA step-up, high risk block + investigate, continuous risk calculation). Dynamic authorization: attribute-based access control ABAC (user attributes, resource attributes, environment context, policy evaluation engine), policy language (XACML evaluation, JSON policies AWS, code-based for custom apps), real-time evaluation (every request evaluated, policies updated centrally, no client-side caching of permissions, fresh authorization).

Access request and approval workflows: Standard access request: employee requests (via help desk ticket Jira Service Desk, specify resource/reason/duration, manager approval required for Confidential+, security approval for Restricted), processing (help desk reviews, verify manager approval, security approval if needed, provision access, document in audit log, notify requester, SLA 24 hours standard / 4 hours urgent), temporary access (specify end date, automatic revocation, reminder before expiration, extend requires re-approval). Privileged access request: elevated permissions (admin, production write, Restricted data access, separate workflow from standard), approval chain (manager approval, security team approval, CISO approval if Restricted, justification documented, audited quarterly), provisioning (PAM system, time-limited, session recorded, comprehensive logging, notify on use), revocation (automatic at expiration, manual early revoke if needed, audit trail of all uses, post-access review). Bulk access requests: onboarding (new hire access bundle, role-based template, HR triggers, manager approves, auto-provision via API), project team (add multiple users to project, manager approval, time-limited to project duration, revoke at project end), annual renewals (recertify annually, manager confirms still needed, revoke if not, track in access review). Emergency access: break-glass (sealed envelopes, password inside, admin access, use only in emergency, change password after use, investigate within 24 hours), approval bypass (document reason, notify CISO, retroactive approval within 24 hours, consequences if unjustified), audit (all break-glass uses audited, root cause analysis, prevent recurrence, update procedures). Access revocation: termination (immediate upon HR notification, account disabled, password changed, access logged revoked, email forwarded 30 days then deleted, return laptop and assets), role change (access review, revoke old role, provision new role, no gap or overlap, manager approval), dormant accounts (no login 90 days triggers review, 180 days auto-disable, re-enable requires approval, annual cleanup). Audit trail: all access changes logged (who requested, who approved, what access, when granted, when revoked, SIEM ingestion), reporting (monthly access changes report, quarterly to management, annual compliance attestation, SOC 2 evidence), retention (7 years minimum, searchable, immutable logs, legal hold capable).

Privileged Access Management (PAM)

Privileged account governance: Privileged account inventory: admin accounts (8 privileged users, separate accounts username-admin, AWS root account locked, GCP org admin, database admin, network admin, documented and reviewed quarterly), service accounts (47 service accounts, API keys, certificates, non-human, rotation policy, minimal permissions, inventory maintained), break-glass accounts (3 emergency accounts, sealed envelopes, stored in safe, password changed after each use, investigated every use). Privileged account standards: separate accounts (privileged separate from standard user, no daily use of admin account, switch to privileged only when needed, audit context switch), naming convention (username-admin for personal admin, svc-appname for service accounts, bg-emergency for break-glass, consistent and identifiable), lifecycle (provision with approval, annual recertification, immediate revoke on separation, audit quarterly, document all changes). Privileged access restrictions: no standing access (just-in-time access preferred, time-limited elevation, revoke after use, re-request if needed), approval required (manager + security approval for privileged, CISO for emergency, document justification, audit trail), session recording (all privileged sessions recorded, video audit trail, searchable by user/time/system, 7-year retention, random review). Break-glass procedures: emergency scenarios (production outage, security incident, disaster recovery, primary admin unavailable, break-glass authorization), access process (retrieve sealed envelope from safe, witness required, document reason, notify CISO, change password immediately after use, return new password to envelope), accountability (investigate every break-glass use within 24 hours, root cause analysis, was it justified, preventive measures, update procedures if gap), audit (comprehensive audit trail, SIEM alert on break-glass access, post-incident review mandatory, quarterly summary to management). Privileged session monitoring: session recording (video recording all privileged sessions, keystroke logging, command logging, searchable archive, compliance requirement SOC 2), real-time monitoring (SOC monitors privileged activity, alerts on suspicious commands rm -rf, unauthorized access attempts, escalate to security team), behavioral analysis (UEBA on privileged accounts, baseline normal activity, anomaly detection, risk scoring, alert on deviations), automated alerts (failed sudo attempts, privilege escalation, unusual hours, geographic anomaly, disabled security controls, immediate investigation).

Credential management and vaulting: Password vaulting: credential vault (evaluating CyberArk vs HashiCorp Vault, centralized credential storage, encrypted at rest AES-256, access logged and audited), check-out mechanism (request credential, approval workflow, time-limited access, credential rotated after use, no permanent knowledge of password), rotation policy (privileged passwords rotated after each use, service account credentials 90 days, API keys 90 days, certificates annual renewal, emergency rotation if compromised). API key management: generation (secure random, sufficient entropy 256-bit, never transmitted in clear, stored in vault), rotation (90-day rotation, automatic via API where supported, manual for others, monitor usage before rotation, deprecated keys revoked after grace period 30 days), scope limitation (minimal permissions, specific APIs only, IP restrictions where possible, expiration date set, revocable), storage (never in source code, secret scanning GitHub, environment variables or vault, encrypted at rest, access logged). Certificate management: internal CA (private certificate authority, issue certificates for internal use, automated enrollment ACME protocol, centralized revocation), certificate lifecycle (issuance with approval, 1-year validity for servers/users, 90-day for services, automatic renewal 30 days before expiry, revocation immediate on compromise), private key protection (never leave server, HSM storage for CA keys, encrypted backups, no email transmission, destroy on decommission), monitoring (certificate expiry monitoring, alert 30/14/7 days before expiry, revocation checking OCSP, certificate transparency logs). SSH key management: key generation (strong keys RSA 4096 or Ed25519, passphrase required for user keys, no passphrase for automated if secured otherwise, regenerate annually), key distribution (no default authorized_keys, centralized key management, provision via automation, revoke on separation), bastion hosts (SSH via bastion only, no direct SSH to production, session logging, MFA for bastion access, limited source IPs), key rotation (user keys annual rotation reminder, service keys via automation, old keys revoked after grace period, audit active keys quarterly). Secrets management in code: no hardcoded secrets (secret scanning GitHub Advanced Security, pre-commit hooks, automated detection, block commits with secrets), environment variables (secrets in environment, injected at runtime, never in code/config files, encrypted in deployment systems), secrets management tools (AWS Secrets Manager for cloud, HashiCorp Vault evaluation, rotation automation, versioning and audit). Vault access control: need-to-know (vault access minimal, security team + specific admins, read access logged, write requires approval), MFA required (vault access requires MFA, no exceptions, frequent re-authentication 4 hours, risk-based step-up), audit logging (comprehensive logs, who accessed what credential when, integration with SIEM, real-time alerts, 7-year retention, immutable). Credential compromise response: detection (credential stuffing alerts, dark web monitoring, breach notification services, user reports, unusual activity), response (immediate rotation, forced password reset, session revocation, investigate usage, determine scope, notify affected), prevention (password manager encouraged 1Password corporate, unique passwords, MFA everywhere, security awareness training, phishing simulation).

Privileged access monitoring and analytics: Privileged User and Entity Behavior Analytics (UEBA): baseline establishment (normal privileged activity patterns, typical commands, systems accessed, time of day, 90-day baseline), anomaly detection (deviation from baseline, unusual commands, systems not normally accessed, off-hours activity, bulk data access, risk score calculated), risk scoring (weighted factors, severity of anomaly, context, user history, peer comparison, threshold alerts), automated response (high-risk score triggers alert, account review, suspend if extreme, investigation required, enhanced logging). Monitoring scope: command logging (all privileged commands logged, sudo logging Linux, PowerShell logging Windows, database audit logging, API calls CloudTrail), file access (privileged access to sensitive files, Confidential/Restricted data access, configuration file changes, /etc modifications Linux), network connections (privileged accounts outbound connections, SSH sessions, RDP connections, unusual destinations, command-and-control indicators), account changes (user creation/deletion, permission changes, password resets, group membership, privilege escalation). Alerting rules: failed privilege escalation (failed sudo attempts 5+, denied admin actions, repeated failures, potential attack), unusual commands (rm -rf on production, database drops, user creation, firewall rule changes, investigate context), off-hours access (privileged access 11pm-6am PKT without justification, geographic anomaly Pakistan→US in short time, holiday/weekend access unusual), bulk access (privileged account accessing large volume data, exfiltration indicators, compression/encryption, external transfer attempts). Investigation procedures: alert triage (security analyst reviews alert within SLA, gather context, check justification, interview user if needed), evidence collection (command logs, session recording, network traffic, file access logs, timeline reconstruction), determination (legitimate business need, policy violation, malicious intent, compromised account, incident or not), action (legitimate: document and close, violation: user counseling + training, malicious: incident response, compromised: credential rotation + investigation + containment). Reporting and metrics: privileged access dashboard (real-time monitoring, active privileged sessions, alerts, risk scores, SOC view), weekly reports (privileged activity summary, top users, top systems, anomalies, investigation outcomes), quarterly metrics (privileged account count, access requests, approvals, session recording coverage, alert volume, false positive rate, investigation backlog), annual attestation (privileged access program effectiveness, metrics trending, compliance status ISO 27001 A.9.2.3, SOC 2 CC6.1, continuous improvement).

Access Reviews & Continuous Monitoring

Quarterly access review process: Review scope: all Confidential/Restricted data access (quarterly review mandatory, managers certify team access, revoke unnecessary, document approval), privileged accounts (admin, production access, Restricted data, every quarter without exception, CISO approval), service accounts (API keys, automation, 90-day rotation aligns with quarterly review, re-certify or revoke), contractor access (review quarterly, contract status check, revoke if contract ended, extend if needed with approval). Review procedure: notification (managers notified via email, list of direct reports and their access, review deadline 14 days, reminder at 7 days and 1 day), review (manager reviews each user, verify access still needed for job function, check with user if uncertain, revoke if not needed, approve if appropriate), certification (manager approves or revokes, justification for keeping access, sign off electronically, audit trail documented), remediation (IT implements revocations, notify affected users, grace period 7 days if needed, verify removal). Automated workflows: access review platform (custom Jira workflow, manager dashboard, one-click approve/revoke, bulk actions, progress tracking), pre-population (auto-populated from IAM systems, group memberships, application access, saves manager time, accuracy), risk flagging (flag high-risk access, dormant accounts 90+ days no login, orphaned accounts manager changed, privilege creep multiple roles), escalation (incomplete reviews escalated to director, then MD, deadline enforcement, compliance requirement). Review metrics 2024: completion rate (98% on time Q1-Q4, 2% delayed with approved extensions, 100% completed eventually, significant improvement from 2023 92%), revocations (847 access revocations, average 212 per quarter, contractors 32%, role changes 28%, no longer needed 25%, dormant 15%), findings (14 orphaned accounts cleaned up, 23 privilege creep cases remediated, 6 contractor access expired but not revoked - corrected, 0 unauthorized access discovered). Attestation: manager attestation (certify access appropriate, accept responsibility, legal accountability, sign off), compliance documentation (SOC 2 evidence, ISO 27001 A.9.2.5, audit work papers, regulatory examination), retention (7 years, access review records, manager certifications, revocation documentation, searchable for audit).

Annual comprehensive access audit: Annual audit scope: all access across all systems (comprehensive audit, not just Confidential like quarterly, entire access inventory, 120 users + 18 contractors + 47 service accounts), all roles and permissions (verify RBAC implementation, role definitions accurate, permissions match documented, no undocumented permissions), segregation of duties (verify SoD controls, financial dual control, developer vs admin, independent security function, conflicts identified and resolved), dormant and orphaned accounts (dormant 180+ days, orphaned manager left/changed, inactive contractors, cleanup required). Audit procedure: data collection (export from all IAM systems, Google Workspace, AWS IAM, database grants, file shares, application access, consolidate), analysis (identify anomalies, dormant accounts, excessive permissions, orphaned accounts, SoD conflicts, privilege creep, undocumented access), risk assessment (rate findings by risk, critical/high/medium/low, business impact, compliance risk, likelihood of misuse), reporting (comprehensive audit report 50+ pages, findings, recommendations, remediation plan, executive summary, detailed appendices), remediation (action plan, owners assigned, due dates, track to closure, verify implementation, re-audit if needed). Annual audit findings 2024: dormant accounts (18 accounts inactive 180+ days, 12 contractors contracts ended, 6 employees on long leave, all disabled), orphaned accounts (9 accounts manager changed/left, access not reviewed, reassigned to new manager, access re-certified), privilege creep (14 users accumulated multiple roles, role change but old access not revoked, streamlined to current role only, 23 total permission removals), SoD conflicts (2 conflicts identified, developer with production admin access emergency from incident, segregated into separate accounts; finance user with both AP and payment approval, delegated approval to manager), undocumented access (5 manual access grants not in RBAC, emergency access during incident, documented retroactively, added to role definitions or revoked). Corrective actions: immediate (disable dormant accounts, revoke orphaned access, fix critical SoD conflicts, 30-day remediation all findings), preventive (automated dormant account alerts, manager change triggers access review, role change workflow improved, quarterly reviews prevent accumulation), detective (enhanced monitoring, privilege creep detection UEBA, orphaned account reports monthly, SoD violation checks automated in provisioning).

Continuous access monitoring: Real-time monitoring: authentication monitoring (failed login attempts 5+ triggers alert, brute force detection, credential stuffing, account lockout notifications, geographic anomalies impossible travel), authorization monitoring (permission denied events, repeated access denials, privilege escalation attempts, unauthorized resource access, SIEM correlation), privileged activity (all privileged access monitored real-time, sudo commands, admin console logins, production changes, database admin activity, SOC oversight). Behavioral analytics (UEBA): user baselines (establish normal behavior per user, systems accessed, data volume, working hours, peer group comparison, 90-day baseline minimum), entity baselines (service accounts, API usage patterns, systems, network connections, data transfer volume, typical vs anomalous), anomaly detection (deviation from baseline, ML algorithms, statistical analysis, risk scoring, contextual evaluation), risk-based alerting (risk score threshold, high-risk auto-alert, medium-risk queue, low-risk logged, tuning to reduce false positives, currently 8% FP rate target <5%). Automated response: account suspension (high-risk activity auto-suspend pending investigation, prevent further damage, notify user and manager, security review required to unlock), MFA step-up (suspicious activity triggers additional MFA challenge, re-authenticate, verify legitimate, block if MFA fails), session termination (risky session terminated, force logout, re-authentication required, investigate context, determine if compromise), ticket creation (auto-create security incident ticket, assign to analyst, SLA tracking, escalation if no response, document investigation). Access anomaly detection: unusual access patterns (access to systems never before accessed, unusual time of day, weekend/holiday access, volume anomaly 10x normal, geographic location unusual Pakistan→US→Pakistan in 1 hour), data access anomalies (Confidential data access by user without business need, Restricted data access without approval, bulk data download, sensitive file access, exfiltration indicators compress/encrypt/transfer), privilege anomalies (non-admin suddenly admin actions, privilege escalation, role change not documented, temporary access not revoked, orphaned high-privilege accounts). Compliance monitoring: policy compliance (password policy compliance, MFA enrollment, encryption verification device, software updates, continuous assessment), configuration compliance (CIS benchmarks, hardening standards, AWS Config rules, drift detection, auto-remediation where safe), access compliance (RBAC policy adherence, SoD enforcement, least privilege verification, quarterly review completion, privileged access approval). Monitoring metrics 2024: alerts generated (8,247 total, 156 high-risk, 892 medium, 7,199 low/info), investigations (156 high-risk investigated 100%, 287 medium investigated 32% random sample, findings: 14 policy violations training, 2 compromised credentials rotated, 0 malicious insiders), false positives (8% FP rate, tuning quarterly, finance and DevOps main sources legitimate unusual activity, improved rules Q3 reduced to 6%), MTTD mean time to detect (8 minutes for high-risk, automated detection, UEBA + SIEM).
