This curriculum spans the design and operational enforcement of security controls across governance, identity, infrastructure, and incident response, comparable in scope to a multi-phase internal capability build for securing enterprise IT operations.

Module 1: Establishing Security Governance and Compliance Frameworks

  • Define roles and responsibilities across security, IT operations, and business units using RACI matrices to clarify accountability for incident response and access control.
  • Select and map organizational controls to regulatory standards such as NIST 800-53, ISO 27001, or GDPR based on industry sector and geographic operations.
  • Implement a formal risk assessment process that integrates with change management to evaluate security impact before system modifications.
  • Develop an audit trail retention policy that balances compliance requirements with storage costs and retrieval performance.
  • Negotiate security clauses in vendor contracts, including right-to-audit provisions and breach notification timelines.
  • Establish a security steering committee with cross-functional leadership to prioritize initiatives and allocate budget based on risk exposure.

Module 2: Identity and Access Management (IAM) Architecture

  • Design role-based access control (RBAC) structures aligned with job functions, minimizing standing privileges through just-in-time access.
  • Integrate privileged access management (PAM) solutions to enforce session monitoring and time-limited elevation for administrative accounts.
  • Implement multi-factor authentication (MFA) across remote access, cloud portals, and critical internal systems using FIDO2 or TOTP standards.
  • Automate user provisioning and deprovisioning workflows using SCIM or custom connectors between HRIS and identity providers.
  • Enforce access certification reviews quarterly, with automated reminders and escalation paths for overdue approvals.
  • Configure single sign-on (SSO) for SaaS applications using SAML 2.0 or OIDC, ensuring identity provider resiliency and failover capabilities.

Module 3: Endpoint Security and Device Hardening

  • Deploy endpoint detection and response (EDR) agents across all corporate devices with centralized telemetry aggregation and behavioral baselining.
  • Enforce disk encryption via BitLocker or FileVault with escrowed recovery keys stored in a secure, access-controlled repository.
  • Standardize OS images with security configurations applied through group policies or configuration management tools like Ansible or Intune.
  • Implement application allow-listing on high-risk systems to prevent unauthorized code execution.
  • Configure mobile device management (MDM) policies to enforce passcode strength, remote wipe, and jailbreak detection for BYOD and corporate devices.
  • Establish a patch compliance threshold requiring critical OS and application updates within 14 days of release.

Module 4: Network Security and Segmentation Strategies

  • Design network zones (e.g., DMZ, internal, management) with stateful firewall rules restricting traffic based on least privilege.
  • Deploy network intrusion detection/prevention systems (NIDS/NIPS) at key ingress/egress points with signature and anomaly-based detection.
  • Implement micro-segmentation in virtualized environments using host-based firewalls or software-defined networking policies.
  • Enforce encrypted communication (TLS 1.2+) for all internal service-to-service traffic in cloud and hybrid environments.
  • Configure DNS filtering to block known malicious domains and enforce logging for forensic analysis.
  • Establish secure remote access via IPsec or SSL VPN with MFA and endpoint posture checks before granting network access.

Module 5: Security Monitoring and Incident Response

  • Centralize logs from firewalls, servers, endpoints, and applications into a SIEM with normalized event parsing and correlation rules.
  • Develop and maintain use cases for detecting suspicious activities such as brute force attacks, data exfiltration, or lateral movement.
  • Define incident severity levels and escalation paths with documented communication protocols for internal and external stakeholders.
  • Conduct tabletop exercises quarterly to validate incident response playbooks and update based on lessons learned.
  • Integrate threat intelligence feeds to enrich alerts with indicators of compromise (IOCs) and automate blocking actions.
  • Preserve forensic evidence using write-blockers and cryptographic hashing during live system investigations.

Module 6: Cloud Security and Shared Responsibility Models

  • Map cloud provider responsibilities (e.g., AWS, Azure) to internal obligations using documented shared responsibility matrices.
  • Enable cloud-native logging and monitoring services (e.g., AWS CloudTrail, Azure Monitor) with real-time alerting on configuration changes.
  • Enforce infrastructure-as-code (IaC) scanning using tools like Checkov or Terrascan to detect misconfigurations before deployment.
  • Implement workload identity federation to avoid long-lived static credentials in cloud environments.
  • Configure storage buckets and databases with default encryption and deny public access unless explicitly justified and logged.
  • Establish cross-account roles with boundary policies to limit privilege escalation in multi-account cloud architectures.

Module 7: Data Protection and Encryption Management

  • Classify data based on sensitivity (e.g., public, internal, confidential) and apply protection controls accordingly.
  • Deploy data loss prevention (DLP) solutions at endpoints, email gateways, and cloud applications to detect and block unauthorized transfers.
  • Implement field-level encryption for sensitive data in databases using application-layer keys or HSM-backed encryption.
  • Manage encryption key lifecycle using a centralized key management system (KMS) with separation of duties for key rotation and access.
  • Enforce secure data disposal procedures for decommissioned storage media using NIST 800-88 sanitization standards.
  • Conduct regular data flow mapping to identify shadow data repositories and enforce consistent protection policies.

Module 8: Change and Configuration Security Controls

  • Integrate security checks into CI/CD pipelines using static application security testing (SAST) and dependency scanning.
  • Require peer-reviewed change approvals for production environments with rollback plans documented in the change management system.
  • Enforce configuration baselines using tools like Puppet, Chef, or Azure Policy to detect and remediate configuration drift.
  • Implement immutable infrastructure patterns for critical services to prevent unauthorized runtime modifications.
  • Log and monitor all configuration changes to network devices, servers, and cloud resources with user attribution.
  • Conduct post-implementation security reviews for high-risk changes to validate control effectiveness and update runbooks.
