Secure Software Requirements
Secure Software Requirements covers eliciting, categorizing, and documenting security requirements before design begins. For CSSLP you must select appropriate elicitation techniques, derive abuse and misuse cases, map compliance scope, and classify constraints such as encryption, authentication, and data protection into the correct requirement categories.

What to know about Secure Software Requirements
You must be able to choose the right elicitation technique for a stated security goal, derive abuse cases from attacker perspective, and correctly categorize each security requirement. The single most important thing is matching the requirement type and scope to the actual system boundary and data flow.
Selecting elicitation techniques such as abuse cases, misuse cases, and attack modeling for threat identification
Deriving PCI-DSS scoping by tracing cardholder data flows through systems and trust boundaries
Classifying security constraints into functional, non-functional, and derived requirement types
Using data classification, privacy requirements, and regulatory drivers to shape security requirements
Watch out for
Common Secure Software Requirements exam traps
- ▸Treating abuse cases as ordinary functional requirements instead of attacker-goal scenarios that reveal missing controls
- ▸Assuming PCI-DSS scope equals only the payment server, ignoring connected systems that store, process, or transmit cardholder data
- ▸Labeling encryption of service-to-service traffic as functional when it is a non-functional constraint on communication

A software company is developing a cloud-based collaboration platform that will be used by government agencies. The platform must adhere to FedRAMP requirements. The security team is defining security requirements and needs to ensure that data in transit is protected. Which of the following requirements is MOST appropriate to include in the security requirements specification to meet FedRAMP requirements?
Hard2When designing a system that must satisfy both HIPAA and local privacy laws, which requirement approach is most appropriate?
Hard3You are leading a threat modeling session for a new cloud-native application. You identify a potential threat where an attacker attempts to inject malicious SQL queries into the search bar. Which technique should you employ to document this behavior during the Secure Software Requirements phase?
Medium4A stakeholder requests a feature that allows users to bypass password complexity requirements for 'internal testing accounts.' As a CSSLP, what is your first step in requirements analysis?

Hard14You are eliciting security requirements for a new online banking application. The business stakeholders are focused on features and have limited security knowledge. You need to ensure that security requirements are complete, unambiguous, and testable. Which technique is MOST appropriate to achieve this?
Hard15When updating requirements for a legacy system to improve its security posture, which THREE actions should the CSSLP prioritize?
Hard16When gathering security requirements, what is the primary challenge when dealing with 'shadow IT' within a large enterprise?
Medium17During a project migration to GDPR compliance, the development team must ensure that personal data is deleted upon user request. Where should these specific data lifecycle constraints be documented to ensure they influence the architectural design?
Hard18An application requires multi-factor authentication (MFA) for administrative access. During requirements gathering, the security team determines that SMS-based MFA is insufficient for high-risk accounts. What documentation artifact should reflect this specific requirement?
Medium19You are a security analyst tasked with reviewing a set of security requirements for a new web application. One requirement states: 'The application must be secure.' What is the PRIMARY issue with this requirement?
Easy20You are reviewing the requirements for a legacy system integration. The system currently transmits credentials over plaintext protocols. What is the priority for the security requirements phase?
Hard21Which TWO inputs are most important when developing 'Abuse Cases'?
Easy22Which TWO methods are effective for eliciting security requirements from non-technical business stakeholders?
Hard23When gathering requirements for a new healthcare application, which regulation must be consulted to ensure the proper handling of Protected Health Information (PHI)?
Easy24You are leading a requirements elicitation session for a new EHR system. A stakeholder from the legal department insists that the system must comply with HIPAA. Another stakeholder from the clinical team wants quick access to patient records for emergency situations. You need to document a security requirement that balances these needs. Which requirement BEST addresses both compliance and usability?
Hard25You are managing requirements for a distributed microservices application. You need to ensure that service-to-service communication is encrypted. Which requirement type best categorizes this constraint?
Hard26You are eliciting security requirements for an application that must comply with PCI-DSS. What is the most effective way to identify the scope of the systems requiring the highest level of security?
Easy27You are a security architect for a FinTech startup building a mobile payment app. The product owner has provided a list of functional user stories but no security requirements. You need to integrate security into the Agile development process without disrupting the sprint cadence. Which approach BEST ensures security requirements are identified and documented continuously?
Medium28A healthcare software development team is building a patient portal that must comply with HIPAA. The team has completed a risk assessment and identified several potential threats. They now need to translate these findings into actionable security requirements. Which of the following is the MOST effective approach to ensure that the security requirements adequately address the identified risks?
Medium29You are analyzing an application to prevent unauthorized API access. Which requirement elicitation technique is best suited to identify potential entry points that an attacker might exploit?
Medium30Which TWO of the following are primary benefits of including security requirements early in the SDLC?
Medium31Which of the following describes the purpose of 'misuse case' modeling?
Easy32A software development team is creating a new e-commerce application. During requirements elicitation, the security architect suggests using misuse cases to identify security requirements. Which of the following BEST describes the primary purpose of misuse cases in this context?
