CompTIA CAS-005 Exam With Confidence Using Practice Dumps

Post-Quantum Cryptography (PQC) preparation is critical to protect data against future quantum computing attacks that could break current cryptographic algorithms (e.g., RSA, ECC). According to the CompTIA SecurityX CAS-005 study guide (Domain 3: Cybersecurity Technology, 3.3), quantum computers with sufficient computational power could perform calculations (e.g., Shor’s algorithm) to decrypt data protected by traditional algorithms. PQC focuses on developing algorithms resistant to such increases in computational resources, ensuring long-term data security.

Option B:Key stretching is a technique to strengthen passwords, not related to PQC.

Option C:PQC algorithms often have higher computational costs, not improved performance.

Option D:Asymmetric encryption is not ideal for large data sets, and PQC is not specifically about this use case.

Option A:This accurately describes PQC’s purpose to safeguard data against quantum-driven decryption.

To meet the requirements of having allendpoints establish telemetry with a SIEM, integrate into an XDR platform, and allow SOC services to monitor the XDR platform, the best approach is to implement Host Intrusion Prevention Systems (HIPS) and a host-based firewall. HIPS can provide detailed telemetry data to the SIEM and can be integrated into the XDR platform for comprehensive monitoring and response. The host-based firewall ensures that only authorized traffic is allowed, providing an additional layer of security.

The hijacked administrator account was used across multiple ASNs (indicating different network locations) in a short time, despite MFA and SSO. This suggests a stolen session or token misuse. Let’s analyze:

A. Token theft detection with lockouts:Useful for detecting stolen SSO tokens, but it’s reactive and may not prevent initial misuse across networks.

B. Context-based authentication:This adds real-time checks (e.g., geolocation, IP changes) to verify login attempts. Given the rapid ASN changes, this proactively mitigates the issue by challenging suspicious logins, aligning with CAS-005’s focus on adaptive security.

C. Decentralize accounts:This removes SSO, increasing complexity and weakening MFA enforcement, which isn’t practical or secure.
