Description

This curriculum spans the full lifecycle of a corporate security systems review, comparable in scope to a multi-phase internal audit program integrating technical assessment, policy alignment, and cross-functional coordination across IT, legal, and third parties.

Module 1: Defining the Scope and Objectives of a Security Systems Review

Determine whether the review will be limited to technical controls or include procedural and administrative safeguards across departments.
Select specific regulatory frameworks (e.g., NIST, ISO 27001, GDPR) that will shape the review’s compliance benchmarks.
Identify which business units and third-party vendors must be included based on data access and risk exposure.
Decide whether the review will be announced or include unannounced assessments to evaluate real-time response capabilities.
Establish boundaries for system access during the review to prevent disruption of mission-critical operations.
Document executive-level risk tolerance thresholds to align the review’s depth and reporting with strategic priorities.

Module 2: Asset Inventory and Classification

Map all hardware, software, and cloud-based systems using automated discovery tools while validating results with manual spot checks.
Classify assets by sensitivity (e.g., public, internal, confidential) using a standardized data classification schema approved by legal and compliance.
Resolve discrepancies between IT asset management databases and actual deployed systems discovered during field assessments.
Integrate shadow IT systems identified during interviews into the official inventory with appropriate risk tagging.
Assign ownership for each critical system to a business unit manager for accountability in remediation workflows.
Update asset classification labels when systems are repurposed or decommissioned to maintain accuracy in risk models.

Module 3: Threat Modeling and Risk Assessment

Conduct STRIDE or PASTA-based threat modeling sessions with application owners to identify design-level vulnerabilities.
Adjust risk scoring based on actual threat intelligence feeds rather than relying solely on historical incident data.
Balance qualitative risk judgments from senior staff with quantitative metrics from existing SIEM and EDR platforms.
Document assumptions made during risk calculations to support auditability and future reassessment.
Decide whether to accept, transfer, mitigate, or avoid specific risks based on cost-benefit analysis and business impact.
Validate threat scenarios with red team findings or penetration test results to avoid theoretical overestimation.

Module 4: Evaluation of Access Control Mechanisms

Review role-based access control (RBAC) assignments in identity management systems for over-provisioning and segregation of duties conflicts.
Audit privileged account usage across servers, databases, and administrative consoles for unauthorized or dormant access.
Assess MFA enforcement policies across cloud applications and determine exceptions that require compensating controls.
Test just-in-time (JIT) access workflows in privileged access management (PAM) systems for reliability and user compliance.
Identify systems that still rely on shared or generic accounts and prioritize migration to individual accountability.
Evaluate integration points between on-premises directories and cloud identity providers for synchronization gaps.

Module 5: Security Control Validation and Testing

Execute vulnerability scans using authenticated and unauthenticated methods to compare exploitability under different conditions.
Verify that firewall rules align with documented network segmentation policies and remove stale or overly permissive entries.
Test endpoint detection and response (EDR) tools by simulating known attack behaviors and measuring detection and response times.
Assess patch management cycles by correlating system inventory data with vulnerability disclosure timelines.
Validate email security controls by sending controlled phishing simulations and measuring user and system response rates.
Review logging completeness across systems to ensure sufficient data is retained for forensic investigations.

Module 6: Incident Response and Recovery Preparedness

Examine incident response playbooks for alignment with current threat landscape and organizational structure.
Test communication trees and escalation procedures during tabletop exercises with legal, PR, and executive teams.
Verify backup integrity and restoration timelines for critical systems through scheduled recovery drills.
Assess whether SOC staffing and shift coverage support 24/7 monitoring requirements without alert fatigue.
Review contracts with cyber insurance providers to confirm incident reporting obligations and coverage triggers.
Document gaps in forensic tooling and data retention policies that could hinder post-breach investigations.

Module 7: Governance, Reporting, and Continuous Improvement

Define key risk indicators (KRIs) and security metrics that will be reported to the board on a quarterly basis.
Establish a remediation tracking system with SLAs for addressing findings, assigning owners, and verifying closure.
Integrate security review outcomes into the enterprise risk management framework for consolidated reporting.
Decide frequency and depth of future reviews based on system criticality and prior risk findings.
Coordinate with internal audit to align control testing schedules and avoid redundant assessments.
Update security policies and standards based on review findings and ensure version control and distribution mechanisms are effective.

Module 8: Third-Party and Supply Chain Security Integration

Assess third-party vendors with access to corporate systems or data using standardized security questionnaires and audit reports.
Review contractual clauses related to data protection, breach notification timelines, and right-to-audit provisions.
Validate that vendor-provided systems undergo the same patch and configuration management cycles as internal systems.
Map data flows between corporate systems and external partners to identify unsecured transmission points.
Monitor vendor security posture continuously using threat intelligence platforms or third-party risk management tools.
Enforce segmentation and zero-trust principles for vendor access, limiting connectivity to only necessary services.
