Description

This curriculum spans the design, integration, and governance of security architecture across enterprise systems, comparable in scope to a multi-phase advisory engagement supporting the implementation of a centralized security program across hybrid environments.

Module 1: Defining Security Architecture Frameworks and Standards

Selecting between ISO/IEC 27001, NIST SP 800-53, and CIS Controls based on organizational compliance requirements and industry sector.
Mapping existing security controls to a chosen framework while identifying gaps in policy coverage and technical enforcement.
Integrating architecture standards with enterprise IT governance bodies to ensure alignment with change management processes.
Customizing baseline control sets to account for legacy systems that cannot support modern cryptographic requirements.
Documenting architectural decisions in a security standards register accessible to audit and operations teams.
Establishing version control and review cycles for security policies to reflect evolving threat landscapes and regulatory updates.

Module 2: Threat Modeling and Risk Assessment Integration

Conducting STRIDE-based threat modeling during system design phases to influence architecture decisions before development.
Assigning ownership for threat model validation to application architects while ensuring security team oversight.
Integrating threat intelligence feeds into risk scoring models to adjust likelihood ratings for specific threat actors.
Using attack trees to quantify potential impact of data exfiltration scenarios on customer trust and legal liability.
Aligning risk treatment options (accept, mitigate, transfer) with business unit risk appetite thresholds.
Documenting residual risks in architecture review boards and obtaining formal risk acceptance from business stakeholders.

Module 3: Identity and Access Management Architecture

Designing role-based access control (RBAC) structures that balance least privilege with operational usability in large enterprises.
Implementing just-in-time (JIT) privileged access for third-party vendors with time-bound approval workflows.
Integrating multi-factor authentication (MFA) across hybrid environments including on-premises and SaaS applications.
Enforcing attribute-based access control (ABAC) policies for data access in cloud data lakes with dynamic tagging.
Managing identity lifecycle synchronization between HR systems and IAM platforms to ensure timely deprovisioning.
Architecting fallback authentication mechanisms for critical systems during directory service outages.

Module 4: Secure Network and Cloud Infrastructure Design

Segmenting network zones using micro-segmentation in virtualized environments to limit lateral movement.
Designing secure hybrid connectivity between on-premises data centers and multiple cloud providers using IPsec and SD-WAN.
Implementing DNS filtering and egress proxy controls to prevent data exfiltration via covert channels.
Configuring cloud security groups and network ACLs to follow zero-trust network access principles.
Deploying inline decryption for TLS inspection at network boundaries while managing privacy and performance trade-offs.
Validating network security policies through automated configuration drift detection and enforcement.

Module 5: Data Protection and Encryption Strategies

Selecting between application-level, database-level, and storage-level encryption based on data sensitivity and access patterns.
Managing encryption key lifecycle using hardware security modules (HSMs) with role-based access and split knowledge.
Implementing tokenization for payment card data in transaction systems to reduce PCI DSS scope.
Designing data masking rules for non-production environments to prevent exposure of PII during testing.
Enforcing data classification policies at rest and in motion using DLP agents and metadata tagging.
Planning for cryptographic agility to support migration from SHA-1 to SHA-256 and future post-quantum algorithms.

Module 6: Security Automation and Orchestration

Integrating SIEM with SOAR platforms to automate incident response playbooks for common attack patterns.
Developing custom parsers for non-standard log formats to ensure consistent event correlation.
Implementing automated vulnerability scanning pipelines that feed into ticketing systems with severity-based SLAs.
Orchestrating containment actions such as host isolation and user account suspension via API integrations.
Validating automation workflows in staging environments to prevent unintended service disruptions.
Designing feedback loops to update threat detection rules based on false positive analysis from automated responses.

Module 7: Governance, Audit, and Continuous Monitoring

Establishing continuous control monitoring using automated compliance checks against CIS benchmarks.
Configuring audit trails for privileged operations with immutable logging in centralized repositories.
Coordinating internal audit schedules with external certification bodies to minimize operational disruption.
Responding to audit findings by updating architectural controls and tracking remediation in issue management systems.
Implementing real-time dashboards for security posture metrics accessible to executive leadership.
Conducting architecture review boards to assess security implications of major infrastructure changes.

Module 8: Incident Response and Architecture Resilience

Designing network architectures to support rapid forensic data collection during active incidents.
Implementing immutable backups and air-gapped recovery systems to counter ransomware threats.
Integrating endpoint detection and response (EDR) telemetry into incident playbooks for faster triage.
Conducting tabletop exercises that validate architectural assumptions under simulated breach conditions.
Architecting redundant command-and-control channels for incident response teams during network outages.
Updating architecture diagrams and runbooks post-incident to reflect lessons learned and control improvements.
