Pass the CompTIA CompTIA CASP CAS-005 Questions and answers with CertsForce

The application allows users to input URLs, which the application then fetches using requests.get(url). This functionality can be exploited if not properly validated, leading to potential security vulnerabilities such as Server-Side Request Forgery (SSRF).

Implementing a code scanner as part of the development pipeline can help identify insecure coding practices, such as unsanitized user inputs and improper handling of external requests. Code scanners analyze the source code for known vulnerabilities and coding errors, enabling developers to remediate issues before deployment.

For a distributed workforce needing access to compliance-bound on-premises systems, VPN access ensures encrypted, authenticated connectivity while limiting exposure. SecurityX CAS-005 emphasizes using VPNs for secure remote access when direct migration to cloud is not possible.

Moving legacy systems to cloud (B) violates the compliance constraints.

SDN security controls (C) are beneficial but do not inherently provide secure remote connectivity.

Microsegmentation (D) is useful for internal lateral movement control but does not solve remote access needs.

To mitigate the identified vulnerabilities, the followingsolutions are most appropriate:

A. Implementing data loss prevention (DLP): DLP solutions help prevent the unauthorized transfer of data outside the organization. This directly addresses the exfiltration of intellectual property by monitoring, detecting, and blocking sensitive data transfers.

E. Enabling modern authentication that supports Multi-Factor Authentication (MFA): This significantly enhances security by requiring additional verification methods beyond just passwords. It addresses the issue of weak user passwords by making it much harder for unauthorized users to gain access, even if they obtain the password.

Other options, while useful in specific contexts, do not address all the vulnerabilities mentioned:

B. Deploying file integrity monitoring helps detect changes to files but does not prevent data exfiltration or address weak passwords.

C. Restricting access to critical file services improves security but is not comprehensive enough to mitigate all identified vulnerabilities.

D. Deploying directory-based group policies can enforce security policies but might not directly prevent data exfiltration or ensure strong authentication.

F. Implementing a version control system helps manage changes to files but is not a security measure for preventing the identified vulnerabilities.

G. Implementing a CMDB platform (Configuration Management Database) helps manage IT assets but does not address the specific security issues mentioned.

Step by Step Explanation:

Understanding the Scenario: The question describes a proactive security measure where an organization maintains a registry of software dependencies and their corresponding hashes. This registry is used to verify the integrity of software packages.

Analyzing the Answer Choices:

A. Supply chain attack: This type of attack involves compromising the software supply chain by injecting malicious code into legitimate software packages.

A crisis management plan defines coordinated communication and response strategies for high-profile incidents that may harm an organization’s public reputation and shareholder confidence. CAS-005 GRC content includes crisis communication planning for regulatory compliance and public relations in the wake of breaches.

A Data Subject Access Request (A) addresses individual data rights, not overall crisis handling.

Business Impact Analysis (B) helps assess potential operational and financial impacts but does not manage public perception during an incident.

Supply chain management (C) is preventative for vendor risks, not responsive to current crises.

Building playbooks for different scenarios and performing regular table-top exercises directly addresses the issues identified in the lessons-learned review. Here's why:

Lost important information for further analysis: Playbooks outline step-by-step procedures for incident response, ensuring that team members know exactly what to document and how to preserve evidence.

Did not utilize the chain of communication: Playbooks include communication protocols, specifying who to notify and when. Regular table-top exercises reinforce these communication channels, ensuring they are followed during actual incidents.

Did not follow the right steps for a proper response: Playbooks provide a clear sequence of actions to be taken during various types of incidents, helping the team to respond in a structured and effective manner. Regular exercises allow the team to practice these steps, identifying and correcting any deviations from the plan.

Investing in better forensic tools (Option A) or requiring certifications (Option C) are also valuable, but they do not directly address the procedural and communication gaps identified. Publishing and enforcing the incident response policy (Option D) is important but not as practical and hands-on as playbooks and exercises in ensuring the team is prepared.

The user-agent string can providevaluable information to distinguish between legitimate and bot-related traffic. It contains details about the browser, device, and sometimes the operating system of the client making the request.

Why Use User-Agent String?

Identify Patterns: User-agent strings can help identify patterns that are typical of bots or legitimate users.

Block Malicious Bots: Many bots use known user-agent strings, and identifying these can help block malicious requests.

Anomalies Detection: Anomalous user-agent strings can indicate spoofing attempts or malicious activity.

Other options provide useful information but may not be as effective for initial determination of the nature of the request:

B. Byte length of the request: This can indicate anomalies but does not provide detailed information about the client.

C. Web application headers: While useful, they may not provide enough distinction between legitimate and bot traffic.

D. HTML encoding field: This is not typically used for identifying the nature of the request.

Attack surface reductionfocuses on minimizingunnecessary services, open ports, and vulnerabilities, reducing the exposure to potential adversaries. This aligns withzero trust and least privilege principles.

Secure Boot (A)helps ensure system integrity but does not minimize exposed services.

Disabling third-party integrations (C)may help, but broader attack surface reduction is the best first step.

Limiting access (D)is important but does not directly reduce exposed services.

A. Implementing allow lists: Allow lists (whitelisting) restrict network communication to only authorized devices and applications, significantly reducing the attack surface by ensuring that only pre-approved traffic is permitted.

F. Implementing a site-to-site IPSec VPN: A site-to-site VPN provides a secure, encrypted tunnel for data transmission between the OT systems and the vendor, protecting the data from interception and tampering during transit.

Other options:

B. Monitoring network behavior: While useful for detecting anomalies, it does not proactively reduce the risk of compromise or sabotage.

C. Encrypting data at rest: Important for protecting data stored on devices, but does not address network communication risks.

D. Performing boot integrity checks: Ensures the integrity of the system at startup but does not protect ongoing network communications.

E. Executing daily health checks: Useful for maintaining system health but does not directly reduce the risk of network-based compromise or sabotage.

In a federated environment divided by region, if user identities are not synchronized across regions, authentication may be slow or fail when employees travel. CAS-005 IAM guidance states that identity synchronization ensures user attributes and credentials are consistently available in all regions, reducing latency and login issues.

Option A creates separate identities, which breaks single identity management.

Option C is unrelated to the login performance issue.

Option D may resolve SSO appliance sync but not cross-region identity data availability.
