The best way is to perform a Software Assurance Maturity Model (SAMM) assessment. SAMM
provides a structured framework to evaluate current software security maturity across people,
process, and technology. The assessment highlights gaps and generates a roadmap tailored to the
organizations development environment.
Option B (threat modeling) only applies to specific applications, not the entire SDLC process. Option
C risks misalignment with technical practices by relying only on CISO goals. Option D (OWASP secure
coding manual) is useful but provides guidelines, not a maturity-based roadmap.
CAS-005 stresses leveraging maturity models for structured, measurable improvements. SAMM
directly addresses this by producing a customized, actionable roadmap for secure coding practices.
Question # 9
A security engineer receives the following findings from a recent security audit:
Data should be protected based on user permissions and roles.
User action tracking should be implemented across the network.
Digital identities should be validated across the data access workflow.
Which of the following is the first action the engineer should take to address the findings?
A. Implement continuous and context-based authentication and authorization B. Use an enhanced user credential provisioning workflow and data monitoring tools C. Improve federation services for digital identities and data access D. Deploy OpenID Connect for API authentication
Answer: A Explanation: The first action is to implement continuous and context-based authentication and authorization (A). Traditional authentication validates users only at login, which creates gaps during active sessions. Continuous authentication ensures validation throughout the data access workflow, incorporating contextual factors like device state, geolocation, and behavioral analysis. This directly aligns with audit findings requiring protection by role, identity validation, and action tracking. Option B improves onboarding and monitoring but does not enforce continuous access control. Option C improves identity federation but does not provide session-by-session validation. Option D secures APIs but is too narrow for organization-wide identity workflows. CAS-005 stresses Zero Trust and context-aware IAM, making continuous authentication and authorization the top priority.
Question # 10
A security analyst is developing a threat model that focuses on attacks associated with the
organization's storage products. The products:
Are used in commercial and government user environments
Are required to comply with crypto-export requirements
Include both hardware and software components that are developed by external vendors in Europe
and Asia
Which of the following are the most important for the analyst to consider when developing the
model? (Select two).
A. Contractual obligations B. Legal hold obligations C. Trust boundaries D. Cloud services enumeration E. Supply chain access F. Homomorphic encryption usage
Answer: C,E Explanation: The most critical considerations are trust boundaries (C) and supply chain access (E). Trust
boundaries define where sensitive data crosses between systems or organizations, requiring strict
cryptographic protections”especially important in government and commercial environments
subject to crypto-export controls.
Supply chain access is also critical because hardware and software are sourced from external
vendors. If suppliers are compromised, attackers could introduce malicious code, backdoors, or
tampered firmware, endangering customers worldwide.
Option A (contractual obligations) and B (legal hold) are compliance-related but not direct security
threats. Option D (cloud services enumeration) is irrelevant unless the storage is cloud-based. Option
F (homomorphic encryption) is an advanced technology but not required for base threat modeling.
CAS-005 highlights modeling adversary capabilities at trust boundaries and accounting for supply
chain risks, making C and E the most important.
Question # 11
A company is migrating from a Windows Server to Linux-based servers. A security engineer must
deploy a configuration management solution that maintains security software across all the Linux
servers. Which of the following configuration file snippets is the most appropriate to use?
A.-------name: deployment hosts: linux_servers remote_user: root tasks: - name: Install security software ansible.builtin.apt: B. linux_servers Linux 3.1 true com.canonical.io C. {"name":"deployment", "hosts":"linux_servers", "remote_user":"Administrator",
"tasks":{"name":"Install security software", "com.microsoft.store.latest"} } D. {"task":"install", "hosts":"linux_servers", "remote_user":"root", "se_linux":"false", "application":"AppX"}
Answer: A Explanation:
The correct snippet is Option A, which shows an Ansible YAML playbook designed to deploy and
maintain security software on Linux servers. Ansible is a configuration management tool widely used
in enterprise environments, and the ansible.builtin.apt module specifically manages package
installation on Debian/Ubuntu-based Linux distributions. This ensures consistent security software
deployment across multiple servers.
Option B is XML-based and does not represent a valid configuration management script. Option C
incorrectly uses JSON format and Reference Microsofts store (com.microsoft.store.latest), which
is irrelevant for Linux. Option D also uses JSON syntax with œAppX,which applies to Windows
applications, not Linux.
CAS-005 emphasizes infrastructure as code (IaC) and automation as best practices for secure system
configuration. YAML-based playbooks in Ansible provide repeatability, auditability, and scalability,
making Option A the most secure and appropriate solution
Question # 12
A game developer wants to reach new markets and is advised by legal counsel to include
specific age-related sign-up requirements. Which of the following best describes the legal
counsel's concerns?
A. GDPR B. LGPD C. PCI DSS D. COPPA
Answer: D Explanation: The correct regulation is COPPA (Childrens Online Privacy Protection Act). COPPA is a U.S. law that requires organizations to obtain parental consent and implement specific protections before collecting personal data from children under the age of 13. Since the legal counsel is advising about age-related sign-up requirements, the concern clearly points to COPPA compliance. GDPR (A) is a European regulation governing privacy and data protection but is broader and not specifically tied to childrens age verification, though it has related provisions. LGPD (B) is Brazils data protection law, similar in scope to GDPR. PCI DSS (C) is focused on protecting cardholder data in payment environments, unrelated to age-related concerns. CAS-005 covers the importance of aligning software platforms with legal and regulatory frameworks. For gaming and online services, COPPA compliance is crucial to avoid fines and reputational harm, ensuring the platform properly handles childrens data.
Question # 13
A security administrator needs to review the efficacy of the detection rules configured on the SIEM
by employing real-world attacker TTPs. Which of the following actions should the security
administrator take to accomplish this objective?
A. Perform an internal penetration test. B. Use adversary emulation. C. Execute an internal vulnerability assessment. D. Perform a threat hunt exercise. E. Ingest new threat intelligence feeds.
Answer: B Explanation: The best option is adversary emulation. Adversary emulation involves simulating real-world attacker Tactics, Techniques, and Procedures (TTPs) based on frameworks like MITRE ATT&CK. Unlike penetration tests, which primarily focus on identifying exploitable vulnerabilities, adversary emulation specifically tests the effectiveness of detection and response capabilities against known adversarial behaviors. Option A (penetration testing) provides value but may not align test cases with SIEM detection rules. Option C (vulnerability assessment) identifies weaknesses but does not test detection rules. Option D (threat hunting) is proactive analysis but does not validate existing SIEM rule coverage in a structured manner. Option E (threat feeds) enrich SIEM data but do not test its efficacy.
CAS-005 identifies adversary emulation as a key strategy for validating detection and response
coverage. It provides measurable results about what alerts are triggered and where detection gaps
exist, enabling organizations to tune SIEM rules for improved efficacy.
Question # 14
A security manager at a local hospital wants to secure patient medical records. The manager needs
to:
Choose an access control model that clearly defines who has access to sensitive information.
Prevent those who enter new patient information from specifying who has access to this data.
Which of the following access control models is the best way to ensure the lowest risk of granting
unintentional access?
A. Rule-based B. Attribute-based C. Mandatory D. Discretionary
Answer: C Explanation: The best option is Mandatory Access Control (MAC). In MAC, access decisions are centrally controlled by the system or administrators, not by individual users. This ensures that healthcare staff who enter patient information cannot grant access to others, thereby preventing accidental or malicious disclosure. MAC enforces strict policies based on data sensitivity and user clearance, which aligns with compliance requirements like HIPAA. Option A (rule-based) defines access through specific rules but is not as rigidly enforced as MAC. Option B (attribute-based) is flexible but could still allow dynamic grants of access. Option D (discretionary) explicitly allows users to assign access rights, which is exactly what must be avoided in this scenario. CAS-005 stresses using centralized, non-discretionary controls when protecting sensitive medical data, making MAC the correct choice for hospitals.
Question # 15
Consultants for a company learn that customs agents at foreign border crossings are demanding
device inspections. The company wants to:
Minimize the risk to its data by storing its most sensitive data inside of a security container.
Obfuscate containerized data on command.
Which of the following technologies is the best way to accomplish this goal?
A. SED B. eFuse C. UEFI D. vTPM E. MicroSD HSM
Answer: A Explanation: The best solution is to use Self-Encrypting Drives (SEDs). SEDs automatically encrypt all data stored on the disk and can be rapidly sanitized or obfuscated by deleting or altering the encryption keys. This provides immediate and secure protection if customs agents demand device access, as the sensitive data inside containers becomes unreadable without the decryption key. Option B (eFuse) and C (UEFI) are hardware mechanisms unrelated to dynamic data protection. Option D (vTPM) provides virtualized key storage but does not obfuscate data quickly under inspection conditions. Option E (MicroSD HSM) is useful for key storage but does not protect all data at scale. CAS-005 highlights hardware-based encryption solutions like SEDs for protecting sensitive data during travel, ensuring both regulatory compliance and rapid response capabilities under hostile conditions.
Question # 16
An organization is developing an in-house software platform to support capital planning and
reporting functions. In addition to role-based access controls and auditing/logging capabilities, the
product manager must include requirements associated with archiving data and immutable backups.
Which of the following organizational considerations are most likely associated with this
requirement? (Select two)
A. Crypto-export management controls B. Supply chain weaknesses C. Device attestation D. Quality assurance E. Legal hold compliance F. Ransomware resilience
Answer: E,F Explanation: The requirements for archiving data and immutable backups directly align with legal hold compliance (E) and ransomware resilience (F). Legal hold compliance ensures that organizations can retain data in a tamper-proof manner when required for litigation, regulatory mandates, or audits. Immutable backups satisfy this by preventing unauthorized changes or deletion, ensuring evidence and records are preserved. Ransomware resilience is also a key factor. Immutable backups allow recovery from ransomware attacks, as attackers cannot encrypt or delete data stored in read-only or write-once media. This reduces downtime and supports business continuity. Options A (crypto-export), B (supply chain), C (device attestation), and D (quality assurance) do not relate directly to data archiving or immutable storage. CAS-005 stresses aligning security controls with business continuity and compliance requirements. By focusing on legal and ransomware-related considerations, the organization ensures both regulatory and operational resilience
Question # 17
A company's Chief Information Security Officer learns that the senior leadership team is traveling to
a country accused of attempting to steal intellectual property saved on laptops. Which of the
following is the best method to protect against this attack?
A. Configure Measured Boot to report any firmware changes. B. Use sanitized devices with remote connections to VDI. C. Deploy self-encrypting drives to protect company data. D. Install tamper-evident stickers over any laptop screws.
Answer: B Explanation: The best option is to provide sanitized devices with remote connections to a Virtual Desktop Infrastructure (VDI). This ensures that no sensitive intellectual property is stored locally on the laptops carried across borders. Even if the devices are inspected, seized, or tampered with, attackers cannot access corporate data since all sensitive files remain within secure, centralized infrastructure. Option A (Measured Boot) reports firmware tampering but does not prevent data theft if the device
is compromised. Option C (self-encrypting drives) protect data at rest but can be bypassed if
customs
agents demand login credentials. Option D (tamper-evident stickers) provide only physical inspection
indicators and are ineffective against sophisticated data theft attempts.
CAS-005 emphasizes secure remote access strategies and temporary œclean laptops for high-risk
travel scenarios. Sanitized laptops with VDI access minimize exposure while maintaining productivity,
making this the strongest mitigation.
Question # 18
A Chief Information Security Officer requests an action plan to remediate vulnerabilities. A security
analyst reviews the output from a recent vulnerability scan and notices hundreds of unique vulnerabilities. The output includes the CVSS score, IP address, hostname, and the list of
vulnerabilities. The analyst determines more information is needed in order to decide which
vulnerabilities should be fixed immediately. Which of the following is the best source for this
information?
A. Third-party risk review B. Business impact analysis C. Incident response playbook D. Crisis management plan
Answer: B Explanation: The correct source is the Business Impact Analysis (BIA). A BIA provides context about which systems and applications are most critical to business operations, regulatory compliance, and customer obligations. While CVSS scores indicate severity in technical terms, they do not reflect the business impact of exploitation. For example, a medium-severity vulnerability on a critical payment system may pose more business risk than a high-severity vulnerability on a test server. Option A (third-party risk review) focuses on vendor security posture, not internal remediation priorities. Option C (incident response playbook) guides response during active incidents, not vulnerability prioritization. Option D (crisis management plan) addresses executive-level communications during crises, not technical risk assessment. By combining vulnerability scan data with BIA context, security teams can prioritize remediation efforts based on business-critical systems, ensuring the highest-risk vulnerabilities are remediated first. This aligns with CAS-005s guidance on risk-based prioritization of remediation efforts.
Question # 19
Engineers at a cloud service provider can now access newly deployed customer environments from
their personal laptops. The engineers are concerned that unmanaged systems may present unknown
vulnerabilities to customer environments, which might become a significant liability to the service
provider. Which of the following deployments provides the most secure solution to prevent access
through non-authorized endpoints?
A. Modifying MDM policies to provide device attestation on all devices connecting to the cloud service's management console B. Requiring that a corporate-licensed and -managed EDR solution is installed on employee-owned laptops C. Configuring the device's certificate-based authentication on the corporate VPN and requiring that all activity in customer environments be performed using the VPN D. Implementing host checking on remote desktop sessions to jump boxes used for managing customer environments
Answer: B Explanation: The best way to reduce liability and secure customer environments is to require that all employeeowned laptops have a corporate-licensed and managed Endpoint Detection and Response (EDR) solution installed. This ensures that devices accessing sensitive customer infrastructure are monitored for malware, unauthorized processes, and suspicious behaviors. EDR provides visibility into endpoint security posture and enforces corporate security baselines, which unmanaged personal devices typically lack. Option A (MDM with attestation) works well for corporate-owned devices but is difficult to enforce reliably across personally owned laptops. Option C (VPN with certificate authentication) ensures encrypted access but does not validate whether the device is secure. Option D (host checking to jump boxes) reduces exposure but still allows unmanaged endpoints to connect indirectly. CAS-005 emphasizes endpoint controls and assurance mechanisms for environments with third-party or bring-your-own-device (BYOD) risk. Deploying managed EDR ensures visibility, consistent policies, and rapid response across all devices, making this the most secure and practical option.
Question # 20
A manufacturing plant is updating its IT services. During discussions, the senior management team
created the following list of considerations:
Staff turnover is high and seasonal.
Extreme conditions often damage endpoints.
Losses from downtime must be minimized.
Regulatory data retention requirements exist.
Which of the following best addresses the considerations?
A. Establishing further environmental controls to limit equipment damage B. Using a non-persistent virtual desktop interface with thin clients C. Deploying redundant file servers and configuring database journaling D. Maintaining an inventory of spare endpoints for rapid deployment
Answer: B Explanation: The best solution is to use a non-persistent virtual desktop infrastructure (VDI) with thin clients (B). Thin clients are inexpensive, easy to replace, and resilient in harsh environments where traditional endpoints may be damaged. With non-persistent VDI, employee desktops are virtualized and reset to a clean state after logout, reducing risks from turnover, malware persistence, or user misconfiguration. Centralized management ensures consistent patching and security updates while minimizing downtime, since damaged thin clients can be swapped quickly with minimal disruption. Option A (environmental controls) may reduce equipment damage but does not address turnover or regulatory retention requirements. Option C (redundant servers and journaling) improves data integrity but does not solve endpoint-related risks or staffing issues. Option D (maintaining spare endpoints) mitigates hardware failures but still relies on managing and configuring full systems, which is inefficient for high-turnover environments. CAS-005 emphasizes virtualization and centralization strategies in environments where operational resilience, rapid recovery, and compliance are critical. Non-persistent VDI with thin clients provides
the most comprehensive solution here.
Question # 21
After discovering that an employee is using a personal laptop to access highly confidential data, a
systems administrator must secure the company's data. Which of the following capabilities best
addresses this situation?
A. OCSP stapling B. CASB C. SOAR D. Conditional access E. Package monitoring
Answer: D Explanation: The best solution is Conditional Access (D). Conditional access policies enforce access requirements based on contextual signals such as device compliance, user identity, location, or risk profile. In this case, the administrator can configure conditional access to ensure that only managed, corporateapproved devices are allowed to access confidential data. If an employee attempts to use a persona laptop, the access request will be blocked or redirected to a secure process (e.g., virtual desktop).
Option A (OCSP stapling) relates to certificate revocation checking and does not control device
access. Option B (CASB) provides cloud access visibility and control but is broader and less precise
than enforcing direct device-level conditional policies. Option C (SOAR) orchestrates responses but is
not primarily designed for access enforcement. Option E (package monitoring) detects software
changes but does not prevent unauthorized device usage.
Conditional access is a core principle in Zero Trust and modern IAM, making it the best solution for
ensuring that sensitive data can only be accessed from trusted devices
Question # 22
A company notices that cloud environment costs increased after using a new serverless solution
based on API requests. Many invalid requests from unknown IPs were found, often within a short
time. Which of the following solutions would most likely solve this issue, reduce cost, and improve
security?
A. Using digital certificates for known customers and performing API authorization through those certificates B. Defining request rate limits and comparing new requests from unknown IPs with a list of knownmalicious IPs C. Setting authentication processes for the API requests as well as proper rate limits according to
regular usage D. Only allowing API requests coming from regions with known customers
Answer: C Explanation:
The best solution is to implement authentication for API requests and apply appropriate rate limiting
(C). Authentication ensures that only authorized customers or systems can access the API, while rate
limiting helps prevent denial-of-service (DoS)-like conditions and cost inflation from excessive or
malicious requests. This addresses both the security (unauthorized access) and cost issues (serverless
billing based on execution).
Option A (digital certificates) is a strong control for authentication but may introduce unnecessary
complexity and does not address rate abuse directly. Option B (rate limits with IP reputation checks)
is useful but insufficient”malicious actors may rotate through new IPs not yet flagged. Option D
(regional restrictions) might reduce some noise traffic but risks blocking legitimate global users and
is not scalable for a modern cloud service.
CAS-005 highlights securing APIs with authentication, authorization, and throttling as best practices.
Thus, the combined approach of API authentication plus rate limiting is the most comprehensive and
effective solution.
Question # 23
An organization would like to increase the effectiveness of its incident response process across its
multiplatform environment. A security engineer needs to implement the improvements using the organization's existing incident response tools. Which of the following should the security engineer use?
A. Playbooks B. Event collectors C. Centralized logging D. Endpoint detection
Answer: A Explanation: The correct answer is Playbooks (A). In incident response, playbooks are structured workflows that define step-by-step actions for specific incident types (e.g., ransomware, phishing, insider threats). They allow SOC analysts to standardize responses across multiple platforms and tools, ensuring consistency and faster mitigation. By leveraging playbooks, organizations integrate existing incident response tools into automated or semi-automated processes, improving efficiency and reducing human error. Option B (event collectors) consolidate logs but do not directly improve response processes. Option C (centralized logging) enhances visibility but does not provide a framework for action. Option D (endpoint detection) expands detection capabilities but does not enhance the process effectiveness of incident response. CAS-005 emphasizes structured response through automation and orchestration. Playbooks, often implemented via SOAR platforms, allow integration of detection, triage, and remediation steps, making them the most effective way to increase incident response maturity.
Question # 24
A threat intelligence company's business objective is to allow customers to integrate data directly to
different TIPs through an API. The company would like to address as many of the following objectives
as possible:
Reduce compute spend as much as possible.
Ensure availability for all users.
Reduce the potential attack surface.
Ensure the integrity of the data provided.
Which of the following should the company consider to best meet the objectives?
A. Configuring a unique API secret key for accounts B. Publishing a list of IoCs on a public directory C. Implementing rate limiting for each registered user D. Providing a hash of all data that is made available
Answer: D Explanation: The best solution is to provide a hash of all data made available (D). Hashing ensures the integrity of the threat intelligence data provided to customers. Clients can verify that the data received via API matches the published hash, ensuring no tampering occurred in transit or at rest. This supports customer trust and aligns with the objective of protecting data integrity while maintaining availability. Option A (API secret keys) improves authentication and reduces attack surface but does not address integrity or compute efficiency. Option B (publishing IoCs publicly) increases attack surface and reduces control over distribution, which conflicts with security objectives. Option C (rate limiting) helps availability and cost control but does not guarantee data integrity.
By providing hashes, the company ensures customers can validate authenticity regardless of delivery
method, reducing the risk of manipulated IoCs. This approach also minimizes compute spend since
hashing is lightweight compared to continuous verification processes.
Therefore, the strongest alignment with all stated objectives”availability, reduced spend, reduced
attack surface, and integrity”is achieved by providing hashes of all threat intelligence data.
Question # 25
A company is adopting microservice architecture in order to quickly remediate vulnerabilities and
deploy to production. All of the microservices run on the same Linux platform. Significant time was
spent updating the base OS before deploying code. Which of the following should the company do to
make the process efficient?
A. Use Terraform scripts while creating golden images B. Create a cron job to run apt-update every 30 days. C. Use snapshots to deploy code to existing compute instances. D. Deploy a centralized update server.
Answer: A Explanation: The best approach is to use Terraform scripts while creating golden images (A). Terraform is an
Infrastructure as Code (IaC) tool that allows organizations to automate infrastructure deployment
consistently across environments. A golden image is a pre-configured, patched, and hardened
system image used as a standard baseline. By creating golden images via Terraform scripts, the
company ensures that every microservice instance is deployed on an already-updated and secure OS.
This eliminates the need for repeatedly patching the base OS before code deployment.
Option B (cron job with apt-update) applies patches but introduces delays (every 30 days) and lacks
consistency across new deployments. Option C (snapshots) saves deployment states but risks
replicating outdated or unpatched images. Option D (centralized update server) is useful but still
requires updates post-deployment, which slows the rollout of microservices.
By automating golden image creation through Terraform, the company gains efficiency, repeatability,
and security assurance, aligning with DevSecOps principles and CAS-005 cloud-native best practices.
