Domain overview
This domain covers integrating security into every phase of the system development lifecycle, from requirements through disposal. ISSMP candidates must show they can govern change control, threat modeling, security documentation, and risk acceptance decisions, and that they can enforce these controls against schedule or cost pressure rather than treating security as a late-stage add-on.
Exam objectives
Selecting the SDLC phase where formal threat modeling belongs, typically design, before build begins
Identifying the document that records applicable security controls during the requirements phase, such as the system security plan or requirements specification
Applying change control so schema or code changes are tested in a staging environment mirroring production before release
Handling vulnerability findings when a project manager wants to bypass remediation because a patch may break the application
Treating threat modeling as a testing or operations activity instead of a design-phase exercise, which misses architectural flaws that are expensive to fix later
Letting a project manager accept risk unilaterally; acceptance must follow the organization's formal risk acceptance and authorization process
Allowing emergency or maintenance changes to skip staging validation and configuration control, leaving production diverging from the approved baseline

During the maintenance phase, a production database needs a schema change. The ISSMP requires that this change be tested in a staging environment that mirrors production. Which process best demonstrates compliance with the 'Separation of Duties' principle?
2What is the primary objective of a 'Security Gate' in an SDLC?
3Which document is primarily responsible for documenting the security controls applicable to a system during the SDLC's requirements phase?
4During a waterfall-to-Agile transition, the development team wants to bypass formal Security Requirements Traceability Matrix (SRTM) documentation in favor of user stories. How should the ISSMP reconcile this?
5An ISSMP is overseeing the integration of security into a new DevOps pipeline using Jenkins. Which stage of the SDLC should the ISSMP enforce the execution of SAST tools to ensure security requirements are met early?
6An ISSMP is performing a security assessment on an application using containerized microservices. The team uses Kubernetes. What is the most effective way to ensure security configurations are consistently applied across all clusters?
7An organization is adopting Infrastructure-as-Code (IaC) using Terraform. The ISSMP wants to ensure no insecure configurations (e.g., S3 buckets with public read) are deployed. What should be integrated into the CI/CD pipeline?
8An organization uses a microservices architecture. How can the ISSMP ensure that inter-service communication is encrypted and that services are authenticated to one another?
9When decommissioning an application, which action should the ISSMP prioritize to ensure data privacy requirements (e.g., GDPR) are satisfied?
10A project manager wants to bypass a security vulnerability finding because 'the patch will break the application'. What is the correct ISSMP response?
11Which phase of the SDLC is most appropriate for conducting a formal Threat Modeling exercise?
12An organization is deploying a globally distributed application. The ISSMP needs to ensure that code changes are signed to prevent tampering. Which process should be implemented in the build pipeline?
13In the context of the SDLC, what is the primary purpose of a 'Software Bill of Materials' (SBOM)?
14What is the primary role of a Change Advisory Board (CAB)?
15A company is integrating a Third-Party API into their application. What must the ISSMP ensure is included in the risk assessment process?
16Which TWO of the following are critical components of a secure SDLC (Software Development Life Cycle) implementation?
17Which THREE factors should an ISSMP consider when selecting security controls for a new system?
18An ISSMP is reviewing the 'Change Control' process for a critical system. Which of the following is an essential element for every change request?
19Which TWO mechanisms are effective for preventing 'insecure direct object references' (IDOR) in a web application during the development phase?
20Which THREE actions are necessary when preparing to decommission a cloud-based Virtual Machine (VM)?
21Which TWO items must be documented in a Change Control Log after a successful production change?
22Which THREE components should be included in an application security requirements document?
23Which THREE items are typically verified in a Security Gate check before a production deployment?
24Which TWO techniques are effective for securing the software supply chain?
25An ISSMP is defining the disposal requirements for a new system that will process regulated financial data. The system uses a combination of on-premises servers with self-encrypting drives, cloud object storage, and encrypted backup tapes. Which action best ensures that data remanence is addressed across ALL media during the disposal phase?
26An organization is initiating a project to develop a new mobile banking application. The ISSMP is tasked with ensuring that security requirements are identified and integrated from the very beginning of the systems development life cycle (SDLC). Which action should the ISSMP take FIRST to achieve this?
27A financial services firm is acquiring a SaaS-based fraud analytics platform. During the due diligence phase of the system lifecycle, the vendor provides a SOC 2 Type II report covering the last 12 months, a completed security questionnaire, and a penetration test summary dated 18 months ago. The ISSMP must decide whether to accept the vendor for integration into the production environment. Which action best satisfies the ISSMP's responsibility at this lifecycle stage?
28An organization is retiring a customer relationship management system that stored personally identifiable information. The system is scheduled for shutdown in 30 days, and the ISSMP must ensure the decommissioning aligns with lifecycle management and data protection obligations. Which action should the ISSMP prioritize?
29An ISSMP is reviewing a project that will replace the organization's customer relationship management (CRM) system. The project manager proposes to reuse the existing security test plan from the legacy CRM to save time and cost. The new CRM is a cloud-based SaaS solution with different data flows and integrations. What should the ISSMP recommend?
30During a post-implementation review of a new enterprise resource planning (ERP) system, the ISSMP discovers that the project team did not perform a security risk assessment during the design phase. The system is now in production and handles sensitive financial data. What should the ISSMP do FIRST?
31An organization is adopting a DevSecOps model and wants to ensure that security requirements are continuously validated throughout the CI/CD pipeline. The ISSMP is asked to define the security control gates. Which approach BEST integrates security into the pipeline while maintaining development velocity?
32An ISSMP is leading the security integration for a new software development project that will use agile methodologies. The project team is distributed across multiple time zones. Which TWO practices are MOST effective for ensuring security requirements are not overlooked in this environment? (Choose two.)
33An ISSMP is leading the secure acquisition of a commercial off-the-shelf (COTS) payroll system that will process employee PII. The vendor will not permit source code review but does provide a completed consensus assessment questionnaire. Which action BEST allows the ISSMP to establish assurance that the product meets the organization's security requirements before signing the contract?
34An ISSMP is reviewing the system development lifecycle (SDLC) for a new payroll application. The organization must comply with PCI DSS because the application will process employee salary payments. At which phase should the ISSMP ensure that PCI DSS requirements are identified and documented?
