CompTIA CySA+ Study Guide: Exam CS0-002

By: Mike Chapple, David Seidl

Overview of this book

The Cybersecurity Analyst (CySA+) certification applies behavioral analytics to improve the overall state of IT security. CompTIA CySA+ meets the ISO 17024 standard and is approved by the U.S. Department of Defense to fulfill Directive 8570.01-M requirements. It is compliant with government regulations under the Federal Information Security Management Act (FISMA). More than just test prep, this book helps you to learn skills to demonstrate your command of all domains and topics covered by the CySA+ exam. The CompTIA CySA+ Study Guide provides complete coverage of all exam objectives for the new CySA+ certification. The CySA+ certification validates a candidate's skills to configure and use threat detection tools, perform data analysis, and identify vulnerabilities with a goal of securing and protecting systems of organizations. You'll study concepts with real-world examples drawn from experts, and hands-on labs. You'll gain insight on how to create your own cybersecurity toolkit. The end-of-chapter review questions will help you reinforce your knowledge. By the end of the book, you’ll have the skills and confidence you need to think and respond like a seasoned professional.

Phases of Incident Response

Organizations depend on members of the CSIRT to respond calmly and consistently in the event of a security incident. The crisis-like atmosphere that surrounds many security incidents may lead to poor decision making unless the organization has a clearly thought-out and refined process that describes how it will handle cybersecurity incident response. Figure 5.1 shows the simple incident response process advocated by NIST.

Notice that this process is not a simple progression of steps from start to finish. Instead, it includes loops that allow responders to return to prior phases as needed during the response. These loops reflect the reality of responses to actual cybersecurity incidents. Only in the simplest of incidents would an organization detect an incident, analyze data, conduct a recovery, and close out the incident in a straightforward sequence...
