CompTIA Updated CAS-004 Exam Questions and Answers by melanie

The developer would most likely implement a Root CA in the autonomous vehicle’s software. A Root CA is the top-level authority in a PKI that issues and validates certificates for subordinate CAs or end entities. A Root CA can be self-signed and embedded in the vehicle’s software, which would reduce the need for external communication and verification. A Root CA would also enable the vehicle to use digital signatures and encryption for secure communication with other vehicles or infrastructure. Verified References:

MITRE ATT&CK is a threat management framework that provides a comprehensive and detailed knowledge base of adversary tactics and techniques based on real-world observations. It can help security analysts to identify, understand, and prioritize potential threats, as well as to develop effective detection and response strategies. MITRE ATT&CK covers the entire lifecycle of a cyberattack, from initial access to impact, and provides information on how to mitigate, detect, and hunt for each technique. It also includes threat actor profiles, software descriptions, and data sources that can be used for threat intelligence and analysis. MITRE ATT&CK is the most likely resource that a security analyst would adopt to implement the most up-to-date and effective security methodologies for their clients. Verified References:

Threat emulation is the method that should be used to test an incident response playbook for insider attacks. Threat emulation is a technique that simulates real-world attacks using realistic scenarios, tactics, techniques, and procedures (TTPs) of threat actors. Threat emulation can help evaluate the effectiveness of an incident response plan by testing how well it can detect, respond to, contain, eradicate, recover from, and learn from an attack.

The tools that can be used to provide key information in the risk register are SCAP scanner and vulnerability scanner. SCAP stands for Security Content Automation Protocol, which is a set of standards and specifications for automating the management of security configuration, vulnerability assessment, and compliance evaluation. SCAP scanner is a tool that can scan systems and networks for security issues based on SCAP content. Vulnerability scanner is a tool that can scan systems and networks for known vulnerabilities and weaknesses. These tools canhelp the security analyst identify and prioritize the risks associated with the systems and networks, as well as provide possible remediation actions. Verified References:
