Summarizing the Techniques Used in Security Assessments

In this sample chapter from CompTIA Security+ SY0-601 Cert Guide, 5th Edition, you will learn how the threat-hunting process leverages threat intelligence.

This chapter is from the book

This chapter covers the following topics related to Objective 1.7 (Summarize the techniques used in security assessments) of the CompTIA Security+ SY0-601 certification exam:

  • Threat hunting

    • Intelligence fusion

    • Threat feeds

    • Advisories and bulletins

    • Maneuver

  • Vulnerability scans

    • False positives

    • False negatives

    • Log reviews

    • Credentialed vs. non-credentialed

    • Intrusive vs. non-intrusive

    • Application

    • Web application

    • Network

    • Common Vulnerabilities and Exposures (CVE) and Common Vulnerability Scoring System (CVSS)

    • Configuration review

  • Syslog/Security information and event management (SIEM)

    • Review reports

    • Packet capture

    • Data inputs

    • User behavior analysis

    • Sentiment analysis

    • Security monitoring

    • Log aggregation

    • Log collectors

  • Security orchestration, automation, and response (SOAR)

This chapter starts by introducing threat hunting and how the threat-hunting process leverages threat intelligence. Then you learn about vulnerability management tasks, such as keeping up with security advisories and performing vulnerability scans. You also learn about the importance of collecting logs (such as system logs [syslogs]) and analyzing those logs in a Security Information and Event Management (SIEM) system. In addition, you learn how security tools and solutions have evolved to provide Security Orchestration, Automation, and Response (SOAR) capabilities to better defend your network, your users, and your organizations overall.
