CompTIA SecurityX (CAS-005) Practice Exam

CompTIA SecurityX (CAS-005) Practice Exam

CompTIA SecurityX (CAS-005) is a high-level cybersecurity certification designed for experienced professionals who want to handle advanced security responsibilities. It focuses on practical and hands-on security skills needed to protect businesses from modern cyber threats. Instead of just knowing theory, this certification ensures you can design, implement, and manage secure systems across complex environments.

This certification is especially useful for professionals working in enterprise-level security or managing large networks. It prepares individuals to think strategically about risk management, incident response, cloud security, and advanced threat defense. With cyberattacks becoming more sophisticated, SecurityX proves that you have the expertise to lead security teams and safeguard organizations effectively.

Course Outline

The CompTIA SecurityX (CAS-005) Exam covers the following topics -

1. Governance, Risk & Compliance (20%)

• Implement governance components: policies, procedures, standards, and guidelines.
• Conduct risk management: impact analysis, risk assessment, prioritization, third-party and privacy risks.
• Understand compliance strategies: frameworks like PCI DSS, ISO/IEC 27000, NIST CSF, CSA, benchmarks, and privacy laws (GDPR, CCPA, etc.).
• Execute threat modeling: actor characteristics, attack patterns, frameworks (ATT&CK, CAPEC, STRIDE), and attack surface analysis.
• Address AI-related security challenges: model threats (e.g., poisoning, prompt injection, deepfakes) and data governance.

2. Security Architecture (27%)

• Design resilient systems and integrate security throughout the system lifecycle (e.g. secure SDLC, CI/CD pipelines).
• Embed security controls: data classification, DLP, hybrid/third-party systems.
• Build access and authentication systems: IAM, federation, PKI, SSO, deprovisioning.
• Secure cloud environments: CASB, shadow IT detection, shared-responsibility, container/orchestration, API security.
• Implement Zero Trust: microsegmentation, segmentation, SASE, SD WAN, identity attestation.

3. Security Engineering (31%)

• Troubleshoot IAM issues: federated identity, MFA, tokens, certificates, biometric systems.
• Secure endpoints and servers: EDR, application control, privilege management, MDM, browser isolation.
• Address complex network security: IPS/IDS, DNSSEC, email security (DKIM/SPF/DMARC), TLS, PKI, DDoS.
• Implement hardware security: TPM, HSM, Secure Boot, tamper detection, firmware security.
• Protect legacy and specialized systems: OT/ICS, IoT, embedded systems.
• Automate security: scripting (PowerShell, Python, Bash), IaC, SOAR, AI-assisted workflows.
• Employ advanced cryptographic concepts: post-quantum cryptography, homomorphic encryption, forward secrecy, envelope encryption.
• Apply cryptographic use cases: data at rest/in transit, digital signatures, tokenization, lightweight crypto.

4. Security Operations (22%)

• Analyze data for monitoring and response: SIEM, event analysis, correlation, baselines, error handling, dashboards.
• Reduce attack surface: vulnerability/attack analysis, mitigations, patching, least privilege, secrets management.
• Leverage threat intelligence and hunting: OSINT, dark web feeds, ISACs, TIPs, IoC sharing (STIX/TAXII), behavioral analytics.
• Conduct incident response: malware analysis, sandboxing, forensic techniques, timeline reconstruction, cloud workload forensics, insider threats.
