CAS-004 Exam Dumps - CompTIA CASP Questions and Answers

Step by Step Explanation:

A: Randomizing the keypad reduces the risk of shoulder-surfing attacks by eliminating predictable patterns.

C: Randomization increases the cognitive load on users, making it harder to input numbers quickly.

D: Additional computational power is minimal and not typically a trade-off.

E and F: Remembering access numbers or weak passwords are unrelated to keypad randomization.

The incident response cycle's preparation phase includes establishing policies and procedures for reporting lost or stolen devices promptly. If an employee's device was missing for 96 hours before being reported, this indicates a lack of awareness or clear procedures on the employee's part, pointing to inadequacies in the preparation phase of the incident response.

File Integrity Monitoring (FIM) is a technology that can detect changes in files, often used to safeguard critical data. Implementing a FIM solution that generates alerts for access by unauthorized IP addresses would ensure that any unauthorized modifications to the file can be detected and acted upon. This helps in mitigating the risk of insider threats, as it would alert to any changes not made through the expected application process.

Immutable infrastructure through containers ensures that the deployed systems remain consistent and resistant to drift. Any changes require rebuilding and redeploying containers, eliminating configuration inconsistencies. This aligns with CASP+ objective 2.2, which emphasizes implementing scalable, secure system configurations.

A Virtual Desktop Infrastructure (VDI) solution meets all the listed requirements: reducing patch management, using standard configurations, allowing for custom resource configurations, and providing access from multiple device types. VDI allows centralized management of desktop environments, where patches and updates can be applied once and distributed across all virtual desktops. It also supports flexible resource configurations and secure remote access from various devices. CASP+ highlights VDI as a solution for centralized, secure desktop management that meets modern enterprise needs for mobility and security.

When conducting a risk assessment for a vendor that provides multiple products, it is important to perform the assessment at the individual product level. Each product might have different risk factors, security requirements, and vulnerabilities, so assessing each one ensures a comprehensive understanding of the risks involved. Assessing randomly or only major products could leave gaps in understanding the risks for smaller but still critical products. CASP+ emphasizes that risk assessments should be detailed and product-specific for a thorough evaluation.

The combination of DAST (Dynamic Application Security Testing) and SAST (Static Application Security Testing) would meet the developers' requirements. DAST is used for runtime testing, capable of simulating attacks like SQL injection and reflected XSS, which fulfills the first requirement. SAST analyzes the code statically to ensure that the application is not vulnerable to issues like memory leaks, fulfilling the second requirement. Implementing both will integrate security testing into the SDLC, addressing the security concerns earlier in the development cycle, as recommended in CASP+.

To securely operate the camera, the security analyst should recommend hardening the camera configuration. This involves several steps:

Changing Default Credentials: Default usernames and passwords are a common vulnerability. They should be replaced with strong, unique passwords.

Disabling Unnecessary Services and Ports: The numerous open ports and insecure protocols should be reviewed, and any unnecessary services should be disabled to reduce the attack surface.

Firmware Updates: Ensuring the camera's firmware is up to date will mitigate known vulnerabilities.

Enable Encryption: If possible, enable encryption for both data in transit and at rest to protect the video stream and other communications from interception.

This approach addresses the identified vulnerabilities directly and ensures that the device is more secure. Simply sending logs to the SIEM or isolating the camera might not fully mitigate the risks associated with default settings and open ports.

For an organization transitioning its Wi-Fi to WPA2/WPA3 Enterprise with EAP-TLS, X.509 certificates are crucial. EAP-TLS (Extensible Authentication Protocol-Transport Layer Security) is a certificate-based authentication protocol, and for it to work, both the client and server must have valid X.509 certificates. This ensures that the mobile devices can authenticate themselves securely to the wireless network. Other options like IPSec configurations or TOTP tokens are not relevant in the context of EAP-TLS wireless authentication. CASP+ highlights the importance of certificate management in secure wireless authentication protocols.

Given that the company requires all its data to be stored within the country and the provider offers only multitenant cloud hosting with minimal security measures, the first step should be to ensure that the data storage complies with legal requirements. This is particularly important because government regulations require data to be stored domestically, which is a legal requirement that takes precedence over other considerations.

Two-factor authentication (2FA) adds an additional layer of security by requiring two forms of identification before granting access to an account or system. Implementing 2FA can significantly reduce the risk of unauthorized access, even if passwords are weak or compromised.

When a security researcher identifies a vulnerability, especially one involving remote code execution, they must navigate a process that protects them legally and ethically. The best advice here is to consult with legal professionals to understand any liabilities, such as potential violations of non-disclosure agreements (NDAs) or intellectual property concerns. Legal consultation ensures that the researcher follows responsible disclosure practices and avoids legal repercussions, which aligns with CASP+ guidance on managing vulnerabilities and the responsible handling of sensitive security information. CompTIA CASP+ emphasizes the importance of adhering to legal and regulatory frameworks when reporting vulnerabilities, especially when dealing with former employers or clients.

In cloud computing models, the security of the physical data center is the responsibility of the Cloud Service Provider (CSP). The CSP is responsible for protecting the infrastructure that runs all of the services offered in the cloud, which includes the physical security of the data center.

Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. This provides users with the assurance that the software is legitimate and safe to install.
