CompTIA Updated CAS-004 Exam Questions and Answers by kaylan

Step by Step Explanation:

Data labeling enables metadata tagging for data classification, which allows systems to filter, act, and enforce policies based on the labels.

Data mapping is used for understanding data flows but does not support automation.

Log scraping and resource tagging are unrelated to enabling system actions based on data classification.

One of the known security concerns with the Distributed Network Protocol version 3 (DNP3), which is used in SCADA systems, is the lack of built-in security features, including authentication. This means that by default, it does not verify the identity of the entities communicating, making it susceptible to unauthorized access and commands.

In the context of a private cryptographic key suspected to be exposed, the best immediate action is to revoke the certificate associated with that key. Revoking the certificate ensures that it cannot be used toestablish new secure sessions, which prevents attackers from using the potentially compromised key to impersonate or decrypt communications. The revocation process typically involves updating the Certificate Revocation List (CRL) or leveraging the Online Certificate Status Protocol (OCSP), both of which are used by clients to check the validity of certificates.

A risk-based threat modeling approach is the best recommendation to prevent the recurrence of major process issues during the development lifecycle. Threat modeling identifies potential security threats, vulnerabilities, and design flaws early in the development process by focusing on the specific risks posed to the system. By proactively identifying and addressing security concerns before they escalate, the development team can avoid the need for significant rewrites and ensure that security is embedded into the design of new projects. CASP+ emphasizes threat modeling as a critical activity to improve secure development practices.
