Figure 1.2 Risks exist at the intersection of threats and vulnerabilities. If either the threat or vulnerability is missing, there is no risk. Figure 1.3 The NIST SP 800-30 risk assessment process suggests that an organization should identify threatsand vulnerabilities and then use that information to determine the level of risk posed by the combination of those threats and vulnerabilities. Figure 1.4 Many organizations use a risk matrix to determine an overall risk rating based on likelihood and impact assessments. Figure 1.5 In an 802.1x system, the device attempting to join the network runs aNAC supplicant, which communicates with an authenticator on the network switch or wireless access point. The authenticator uses RADIUS to communicate with an authentication server. Figure 1.6 A triple-homed firewall connects to three different networks, typically an internal network, a DMZ, and the Internet. Figure 1.7 A triple-homed firewallmay also be used to isolate internal network segments of varying trust levels. Figure 1.8 Group Policy Objects (GPOs) may be used to apply settings to many different systems at the same time. Figure 1.9 NIST divides penetration testing into four phases. Figure 1.10 The attack phase of a penetration test uses a cyclical process that gains a footholdand then uses it to expand access within the target organization.

This book will help you to assess your knowledge before takingthe exam, as well as provide a stepping-stone to further learning in areas where you may want to expand your skillset or expertise. Before you tackle the CSA , you should already be a security practitioner. CompTIA suggests that test takers have between 3 and 4 years of existing handson information security experience. You should also be familiarwith at least some of the tools and techniques described in this book. You don’t need to know every tool, but understanding how to approach a new scenario, tool, or technology that you may not know using existing experience is critical to passing the CSA exam. For up-to-the-minute updates covering additions or modifications to the CompTIAcertification exams, as well as additional study tools, videos, practice questions, and bonus material, be sure to visit the Sybex website and forum at CompTIA CompTIA is a nonprofit trade organization that offers certification in a variety of IT areas, ranging from the skills that a PC support technical needs, which are covered in theA exam, to advanced certifications like the CompTIA Advanced Security Practitioner, or CASP certification. CompTIA divides its exams into four different categories based on the skill level required for the exam and what topics it covers, as shown in the following table: Foundational Professional IT Fundamentals A Specialty Mastery CDIA CASPCloud with Virtualization CTT CSA Cloud Essentials Linux Healthcare IT Tech Mobility Network Security Project Server CompTIA recommends that practitioners follow a cybersecurity career path as shown here: As you can see, despite the A , Network , and Security falling into the Professional certification category, theCybersecurity Analyst exam is a more advanced exam, intended for professionals with hands-on experience and who possess the knowledge covered by the prior exams. CompTIA certifications are ISO and ANSI accredited, and they are used throughout multiple industries as a measure of technical skill and knowledge. In throughout multipleindustries as a measure of technical skill and knowledge. In addition, CompTIA certifications, including the Security and the CASP, have been approved by the U.S. government as Information Assuance baseline certifications and are included in the State Department’s Skills Incentive Program. The Cybersecurity Analyst Exam The CybersecurityAnalyst exam, which CompTIA refers to as the CSA , is designed to be a vendor-neutral certification for cybersecurity, threat, and vulnerability analysts. The CSA certification is designed for security analysts and engineers as well as Security Operations Center (SOC) staff, vulnerability analysts, and threat intelligence analysts. It focuses onsecurity analytics and practical use of security tools in real-world scenarios. It covers four major domains: Threat Management, Vulnerability Management, Cyber Incident Response, and Security Architecture and Tool Sets. These four areas include a range of topics, from reconnaissance to incident response and forensics, while focusing heavily onscenario-based learning. The CSA exam fits between the entry-level Security exam and the CompTIA Advanced Security Practitioner (CASP) certification, providing a mid-career certification for those who are seeking the next step in their certification and career path. The CSA exam is conducted in a format that CompTIA calls “performancebasedassessment.” This means that the exam uses hands-on simulations using actual security tools and scenarios to perform tasks that match those found in the daily work of a security practitioner. Exam questions may include multiple types of questions such as multiple-choice, fill-in-the-blank, multiple-response, dragand-drop, and image-based problems.CompTIA recommends that test takers have 3–4 years of information security– related experience before taking this exam. The exam costs 320 in the United States, with roughly equivalent prices in other locations around the globe. More details about the CSA exam and how to take it can be found at . Study and Exam Preparation Tips A testpreparation book like this cannot teach you every possible security software package, scenario, or specific technology that may appear on the exam. Instead, you should focus on whether you are familiar with the type or category Instead, you should focus on whether you are familiar with the type or category of technology, tool, process, or scenario asyou read the book. If you identify a gap, you may want to find additional tools to help you learn more about those topics. CompTIA recommends the use of NetWars-style simulations, penetration testing and defensive cybersecurity simulations, and incident response training to prepare for the CSA . Additional resources for hands-on exercises includethe following:
