CAS-004 Exam Dumps - CompTIA Advanced Security Practitioner (CASP+) Exam

Due care refers to the effort made by an ordinarily prudent or reasonable party to avoid harm to another party. By not reporting the gaps in the inventory system, the assessor is neglecting their responsibility and not exercising the due care that is expected of them, which could lead to legal ramifications for non-compliance or other security breaches.

Using digital certificates for authentication is a secure method to control access to laptops and other devices. A device certificate can serve as an authenticator by providing a means for the device to prove its identity in a cryptographic manner. This certificate-based authentication is commonly used in enterprise environments for strong authentication.

Signed applications ensure the integrity of the application by verifying that the source code has not been tampered with. Digital signatures provide a cryptographic guarantee that the software is exactly as the developer released it.

The best approach to reduce the company's risk is to segregate the enterprise IT servers and supervisory industrial systems. Creating a new network segment and using a Next-Generation Firewall (NGFW) to enforce a strict segmentation policy will help to isolate the systems and protect against potential attacks. Additionally, implementing a Wireless Intrusion Detection System (WIDS) can help monitor the spectrum for unauthorized devices or interference.

Digitally signed third-party certificates provide greater security assurance because they are verified by trusted Certificate Authorities (CAs) and offer protection against on-path (man-in-the-middle) interception. Private-key Certificate Signing Request (CSR) signage helps ensure that communication cannot be intercepted or modified by malicious actors. Self-signed certificates, on the other hand, are not trusted outside the local environment and do not provide the same level of protection against on-path attacks. CASP+ emphasizes the security benefits of using third-party-signed certificates for securing communications over public networks.

High availability ensures continuous operation despite hardware failures by leveraging redundant components like clustered firewalls or failover systems. This aligns with CASP+ objective 3.1, which focuses on implementing availability and redundancy mechanisms in disaster recovery planning.

A machine-learning-based data security service provides dynamic discovery, anomaly detection, and behavioral analysis. It effectively identifies changes and suspicious activity across large-scale environments, such as object storage in the cloud. This aligns with CASP+ objective 4.3, emphasizing the use of advanced analytics and ML to improve data security.

To meet the mobile platform security requirements, the manufacturer should implement the following technologies:

eFuse: This hardware feature helps track and prevent unauthorized firmware by physically "blowing" fuses to record events, such as firmware tampering, making it impossible to revert to older, unapproved firmware.

Secure boot: This ensures that only trusted and authorized firmware can be loaded during the boot process, preventing malicious or unauthorized software from running.

Secure enclave: A secure enclave is used to store sensitive information like biometric data in a hardware-isolated environment, protecting it from tampering or unauthorized access.

These three solutions provide the tamper resistance, secure firmware validation, and protection of sensitive data required for the platform. CASP+ emphasizes the use of hardware-based security features for protecting sensitive information and enforcing secure boot processes in embedded and mobile systems.
