CASP+ (CAS-004) Domain 3: Research, Analysis, and Assessment

Domain Overview

This domain ensures cybersecurity professionals can conduct effective research, analyze security trends, assess threats, and evaluate system vulnerabilities. Critical for making strategic decisions and recommending secure solutions.

What You Will Learn

Tip: Always validate the credibility and timeliness of your intelligence sources when conducting cybersecurity research.

Threat Modeling

Threat modeling is a structured approach to identifying and prioritizing potential attack paths against critical systems. It helps organizations anticipate risks and implement effective countermeasures. Frameworks like STRIDE and PASTA are commonly used for this purpose:

  • STRIDE: Focuses on six threat categories: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege.

    Learn more about STRIDE at the OWASP Threat Modeling Guide.

  • PASTA (Process for Attack Simulation and Threat Analysis): A risk-centric methodology that aligns business objectives with technical security requirements.

    Learn more about PASTA at the ThreatModeler PASTA Overview.

Vulnerability Research

Vulnerability research involves identifying, evaluating, and reporting software and hardware vulnerabilities. This process is essential for mitigating risks and maintaining a secure environment.

  • Common Vulnerabilities and Exposures (CVE): A database of publicly disclosed vulnerabilities.

    Explore the CVE database at MITRE CVE.

  • National Vulnerability Database (NVD): Provides detailed information about vulnerabilities, including CVSS scores and mitigation strategies.

    Visit the NVD at NIST NVD.

Threat Intelligence

Threat intelligence involves gathering and analyzing data about potential or existing threats to an organization. Sources include:

  • Open Source Intelligence (OSINT): Publicly available information, such as MITRE ATT&CK and Shodan.

    Learn more about OSINT at MITRE ATT&CK.

  • Commercial Threat Feeds: Paid services like Recorded Future and Anomali provide actionable intelligence.
  • Information Sharing and Analysis Centers (ISACs): Industry-specific organizations that share threat intelligence.

Security Trend Analysis

Security trend analysis involves monitoring the evolving threat landscape, analyzing cybersecurity news, and understanding emerging technologies to anticipate and adapt defenses.

  • Threat Landscape Reports: Review reports from ENISA, Verizon, and IBM to understand the latest attack vectors and vulnerabilities.

    Explore ENISA’s threat landscape report at ENISA Threat Landscape.

  • Emerging Technologies: Understand how AI, ML, and blockchain are transforming cybersecurity.

🛡️ Vulnerability Analysis

Vulnerability analysis is a critical process for identifying, evaluating, and prioritizing security weaknesses in systems, applications, and networks. This ensures that organizations can mitigate risks effectively and maintain a strong security posture.

  • CVSS (Common Vulnerability Scoring System): A standardized framework for assessing the severity of vulnerabilities. CVSS scores help prioritize remediation efforts based on the potential impact.

    Learn more about CVSS at the FIRST CVSS Overview.

  • NVD (National Vulnerability Database): A comprehensive repository of publicly disclosed vulnerabilities. It provides detailed information, including CVSS scores, affected products, and mitigation strategies.

    Explore the NVD at the NIST National Vulnerability Database.

  • Vulnerability Scanners: Tools like Nessus, OpenVAS, and Qualys are used to automate the detection of vulnerabilities in systems and networks. These tools generate detailed reports to guide remediation efforts.

    Learn more about Nessus at the Tenable Nessus, and explore OpenVAS at the OpenVAS Official Website.

  • Patch Management: Once vulnerabilities are identified, patch management ensures timely updates to address security flaws. This process involves testing, deploying, and verifying patches across systems.

    Learn more about patch management best practices at CISA Patch Management Guide.

📈 Security Trend Evaluation

Security trend evaluation involves monitoring the evolving threat landscape, analyzing cybersecurity news, and understanding emerging technologies to anticipate and adapt defenses. This proactive approach helps organizations stay ahead of attackers and implement effective security measures.

  • Threat Landscape Reports: Regularly review reports from trusted organizations like ENISA, Verizon, and IBM to understand the latest attack vectors, threat actors, and vulnerabilities.

    Explore the latest threat landscape report at ENISA Threat Landscape.

  • Cybersecurity News and Alerts: Stay updated with real-time news and alerts from sources like CISA, Krebs on Security, and The Hacker News to identify emerging threats and vulnerabilities.

    Visit CISA’s alerts at CISA Cybersecurity Alerts.

  • Emerging Technologies: Understand how technologies like Artificial Intelligence (AI), Machine Learning (ML), and blockchain are being used in cybersecurity to enhance threat detection and response capabilities.

    Learn more about AI in cybersecurity at Gartner AI Insights.

  • Zero-Day Exploits: Monitor zero-day vulnerabilities and exploits through platforms like MITRE ATT&CK and Zero Day Initiative (ZDI) to prepare for potential attacks.

    Explore zero-day vulnerabilities at Zero Day Initiative.

  • Security Frameworks and Standards: Align your evaluations with frameworks like NIST CSF and ISO 27001 to ensure a structured approach to security trend analysis.
