CompTIA CompTIA CASP CAS-004 New Questions

Theddtool creates a bit-for-bit copy of a hard drive, preserving its contents exactly as they are. This is essential for forensic analysis, as it ensures the integrity of evidence. This aligns with CASP+ objective 5.2, which emphasizes forensic tools and techniques for preserving and analyzing digital evidence.

Step by Step Explanation:

Digital signatures provide non-repudiation, ensuring that the sender cannot deny signing a transaction. This mechanism ties the transaction to the entity through cryptographic assurance.

Federation involves identity management and authentication but does not address non-repudiation.

Key escrow is used for securely storing encryption keys and is unrelated to transaction agreements.

Salting hashes enhances password security but does not support transactional non-repudiation.

The netstat -tulpn command is used to display network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. The -tulpn options specifically show TCP and UDP connections with the process ID and the name that is listening on each port,which would provide the necessary information to identify if FTP is running and on which port without turning the service off. This information can then be used to create a precise firewall rule to prevent the FTP service from being exploited.

To prevent similar issues from occurring again, the CISO should create an effective communication plan and ensure all employees are aware of it. A clear communication plan ensures that critical security information, such as breaches or vulnerabilities, is promptly communicated to the right stakeholders (e.g., the CEO) in a timely manner, preventing situations where the media reports on breaches before internal teams are fully informed. CASP+ emphasizes the importance of having structured communication protocols during security incidents to ensure accurate and timely responses.
