Data Security & Encryption

Data classification: Classification levels: Public (no confidentiality, marketing materials, public website, press releases, no controls beyond integrity), Internal (business use, employee directory, org charts, policies, basic access controls), Confidential (sensitive business, client data, source code, financials, encryption + access controls), Restricted (highly sensitive, PII, PHI, payment data, financial records, strict controls + audit). Handling requirements: Public (no restrictions, publish freely, verify integrity, version control), Internal (employee access only, no public sharing, basic encryption email attachments, authorized devices), Confidential (need-to-know access, encryption mandatory, MFA required, logged access, annual access review), Restricted (minimal access, encryption at rest + in transit, data masking, audit all access, quarterly review, DLP monitoring). Data labeling: electronic (metadata tags, file headers, email subject tags, automated classification tools), physical (header/footer markings, color coding, destruction requirements, locked storage). Classification ownership: data owner (business unit, determines classification, approves access, periodic review), data custodian (IT team, implements controls, monitors compliance, reports violations), data user (employees, follow handling requirements, report incidents, awareness training annual).

Encryption implementation: Data at rest: databases (RDS encrypted storage, AES-256, AWS KMS keys, automated backups encrypted), file storage (S3 default encryption, EBS volumes encrypted, snapshots encrypted, versioning encrypted), application data (application-level encryption for sensitive fields, envelope encryption, field-level encryption, tokenization for PCI data), laptops (full disk encryption BitLocker/FileVault, TPM chip, pre-boot authentication, recovery key escrow).

Encryption algorithms: symmetric (AES-256 for bulk encryption, ChaCha20-Poly1305 for mobile, GCM mode for authenticated encryption), asymmetric (RSA-2048 minimum for key exchange, ECC for performance, hybrid encryption), hashing (SHA-256 for integrity, bcrypt for passwords, Argon2 preferred, no MD5/SHA1).

Data lifecycle management: Data collection: minimize collection (collect only necessary, justify each field, progressive profiling, consent management), source validation (verify data source, authentication, integrity checks, provenance tracking), privacy notices (clear disclosure, purpose limitation, consent mechanisms, GDPR Article 13/14 compliance). Data processing: purpose limitation (process only for specified purpose, documented purposes, compatibility assessment for new uses, re-consent if incompatible), access controls (role-based, need-to-know, least privilege, logging all access, quarterly reviews), data quality (validation at input, accuracy checks, de-duplication, correction workflows). Data storage: retention schedules (by data type, legal requirements, business need, automated enforcement), storage optimization (hot/warm/cold tiers, compression, archival, cost optimization), backup (RPO 1 hour, RTO 4 hours, geo-redundant, encrypted, tested quarterly). Data sharing: internal sharing (department boundaries, access approvals, audit trail, need-to-know), third-party sharing (DPAs required, sub-processor approvals, SCCs for international, vendor security assessments), client data (client owns data, process per instructions only, no unauthorized access, return/delete on termination). Data deletion: secure deletion (multi-pass overwrite, degaussing for magnetic media, physical destruction for hardware, certificate of destruction), backup purging (90-day backup retention, purge from all backups, verify deletion, document for audit), right to erasure (GDPR Article 17, 30-day grace period, hard delete + backup purge, notify third parties).

Access Control & Identity Management

Identity and access management (IAM): User lifecycle: provisioning (onboarding checklist, HR notification triggers account creation, access based on role, approval workflows), changes (role change, transfer, promotion triggers access review, manager approval, audit trail), deprovisioning (termination/resignation triggers immediate access revocation, account disabled, password changed, email forwarded, exit interview). Account types: user accounts (employees, unique ID, personalized, MFA mandatory, password policy enforced), service accounts (applications, non-human, API keys/certificates, rotation policy, minimal permissions), admin accounts (privileged access, separate from user account, MFA mandatory, session recording, just-in-time access). Single Sign-On (SSO): implementation (Google Workspace as IdP, SAML 2.0, OAuth 2.0, centralized authentication), integrated applications (GitHub, AWS via federated, Slack, Jira, 15+ apps integrated), benefits (one password, MFA once, centralized access control, easier offboarding). Password policy: complexity (12 characters minimum, uppercase/lowercase/number/symbol, no dictionary words, not based on username), rotation (90 days expiry, 24 password history, no reuse, exceptions for service accounts with other controls), storage (bcrypt hashed, salted, never plaintext, no reversible encryption, secure password manager encouraged - 1Password corporate). Multi-factor authentication (MFA): coverage (100% employees, 100% privileged access, 100% VPN, 100% production systems access), methods (authenticator apps preferred - Google Authenticator/Authy, SMS backup, hardware tokens YubiKey for admins, biometric for mobile), enforcement (mandatory, no exceptions, grace period 7 days new employees, account locked if non-compliant).

Role-based access control (RBAC): Roles defined: Developer (source code read/write, dev environment access, no production write, code review required), Senior Developer (production read-only, deployment approval, code review authority, mentor juniors), Tech Lead (production read/write with approval, architecture decisions, security review, team lead), DevOps Engineer (infrastructure access, production deployment, monitoring, backup/restore), Security Analyst (security tools, log access, incident response, vulnerability management), Admin (privileged access, infrastructure admin, break-glass, session recorded). Permission model: resources (AWS accounts, databases, code repositories, applications, networks), actions (read, write, execute, delete, admin), conditions (IP restrictions, time-based, MFA required, approval workflows). Least privilege principle: default deny (no access by default, explicit grants only, minimal permissions to perform job), need-to-know (access only to required data, department boundaries, project-based access), separation of duties (no single person full control, deployment requires approval, financial transactions dual control), just-in-time access (temporary elevated access, time-limited, request/approval, revoked automatically). Access reviews: quarterly reviews (managers review team access, certify appropriate, revoke unnecessary, document approval), annual audits (comprehensive access audit, identify dormant accounts, cleanup unused, verify separation of duties), automated monitoring (detect privilege creep, alert on anomalous access, correlate with HR data, orphaned accounts). Privileged access management (PAM): break-glass accounts (emergency access, sealed envelope, used only in emergency, change password after use, investigate all usage), session recording (all privileged sessions recorded, video audit trail, searchable, 7-year retention), approval workflows (privileged access requires approval, manager + security, justification required, time-limited grant), credential vaulting (privileged credentials in vault - CyberArk/HashiCorp Vault, check-out mechanism, rotation after use, audit all access).

Access monitoring and anomaly detection: User and Entity Behavior Analytics (UEBA): baseline behavior (normal working hours, typical access patterns, usual locations, peer group comparison), anomaly detection (off-hours access, unusual volume, geographic anomaly, privilege escalation), risk scoring (risk score per user, weighted factors, threshold alerts, automated response), machine learning (supervised learning on labeled incidents, unsupervised for unknown threats, continuous model improvement). Access logging: comprehensive logging (all authentication attempts, authorization decisions, resource access, privileged actions), log content (timestamp, user, source IP, action, resource, result success/fail, session ID), centralized collection (SIEM, CloudWatch Logs, S3 long-term, real-time + historical analysis), retention (7 years for audit, compliance, searchable, tamper-proof). Alerting rules: failed login attempts (5 failed attempts triggers alert, potential brute force, account lockout after 10 attempts, unlock requires help desk), impossible travel (login from Pakistan then 30 minutes later from US, geographic anomaly, suspend account pending investigation), privilege escalation (non-admin suddenly admin actions, unauthorized sudo, investigate immediately), dormant account activity (account inactive 90 days then suddenly active, compromised credential risk, require password reset). Automated response: account suspension (high-risk activity auto-suspend, require investigation, prevent further damage), MFA step-up (risky action triggers additional MFA, re-authentication, confirm legitimate), notification (alert user via SMS/email, confirm if authorized, report if unauthorized), ticketing (create security incident ticket, assign to analyst, SLA tracking, escalation if no response).

Monitoring, Detection & Response

Security Operations Center (SOC): Coverage: 24/7/365 monitoring (Islamabad office 6am-6pm PKT, Rawalpindi office 6pm-6am PKT, on-call weekends/holidays, redundant coverage), staffing (3 security analysts, 1 senior analyst/SOC lead, CISO on-call escalation, 30-minute response SLA), tools (SIEM for log aggregation/correlation, EDR for endpoint visibility, SOAR for automation, threat intelligence feeds).

Alert triage: initial review (analyst reviews alert, gather context, check false positive indicators, 15-minute SLA), enrichment (OSINT lookup, threat intel correlation, similar historical incidents, user/asset context), severity assessment (CVSS scoring, business impact, data sensitivity, exploitability, assign P1-P4), escalation decision (P1/P2 escalate immediately, P3 investigate further, P4 track and monitor, on-call notification for P1). Incident classification: P1 Critical (active data breach, ransomware encryption, production down, sensitive data exfiltration, <15 minute response SLA, executive notification immediate), P2 High (breach attempt unsuccessful, malware contained, service degradation, vulnerability exploitation, <1 hour response, management notification), P3 Medium (policy violation, suspicious activity, malware detected and quarantined, non-critical service impact, <4 hour response), P4 Low (informational, failed attack attempt, security configuration issue, minor policy violation, <24 hour response). Incident metrics: mean time to detect (MTTD <8 minutes for P1, automated detection, baseline 2024), mean time to respond (MTTR <15 minutes P1, <1 hour P2, documented 2024 100% P1 SLA compliance), false positive rate (targeting <5%, currently 8%, continuous tuning, analyst feedback), escalation rate (30% of alerts escalate to incidents, 2% become P1/P2, appropriate triage).

Incident response playbooks: Playbook structure: incident type (malware, phishing, DDoS, data breach, insider threat, account compromise, 15 documented playbooks), detection (how to identify, indicators, data sources, automated alerts), triage (severity assessment, impact determination, escalation criteria, notification requirements), containment (immediate actions, isolate affected systems, prevent spread, preserve evidence), eradication (remove threat, patch vulnerability, restore from clean backup, verify clean), recovery (restore services, verify functionality, monitor for reoccurrence, return to normal), post-incident (lessons learned, root cause analysis, documentation, preventive measures). Example playbook - Ransomware: detection (EDR alert file encryption, user report cannot access files, ransom note observed, suspicious process behavior), triage (identify patient zero, determine encryption scope, data backup status, business impact assessment), containment (isolate infected systems - network disconnect, disable user account, block C2 IPs, preserve forensic image), eradication (identify ransomware variant, check decryption availability, malware removal, vulnerability patching), recovery (restore from immutable backups, verify data integrity, malware scan, phased restore - critical first), post-incident (root cause - phishing email?, user training, email filtering rules, immutable backup validation).
