Summary
This course covers network defense and incident response methods, tactics, andprocedures that are in alignment with industry frameworks such as NIST 800-61r2(Computer Security Incident Handling Guide), US-CERT's National Cyber IncidentResponse Plan (NCIRP), and Presidential Policy Directive (PPD)-41 on Cyber IncidentCoordination. It is ideal for candidates who have been tasked with the responsibilityofmonitoring and detecting security incidents in information systems and networks, andforexecuting standardized responses to such incidents. The course introduces tools,tactics, and procedures to manage cybersecurity risks, identify various types of commonthreats, evaluate the organization's security, collect and analyze cybersecurityintelligence, and remediate and report incidents as they occur. This course providesacomprehensive methodology for individuals responsible for defending the cybersecurityoftheir organization.

This course is designed to assist students in preparing for the CertNexus CyberSecFirst Responder (Exam CFR-310) certification examination. What you learn andpractice in this course can be a significant part of your preparation.

In addition, this course and subsequent certification (CFR-310) meet all requirementsfor personnel requiring DoD directive 8570.01-M position certification baselines:
• CSSP Analyst
• CSSP Infrastructure Support
• CSSP Incident Responder

Prerequisites
To ensure your success in this course, you should meet the following requirements: •At least two years (recommended) of experience or education in computer networksecurity technology or a related field. •The ability or curiosity to recognize information security vulnerabilities andthreats in the context of risk management. •Foundational knowledge of the concepts and operational framework of commonassurance safeguards in network environments. Safeguards include, but are notlimited to, firewalls, intrusion prevention systems, and VPNs. •General knowledge of the concepts and operational framework of common assurancesafeguards in computing environments. Safeguards include, but are not limited to,basic authentication and authorization, resource permissions, and anti-malwaremechanisms. •Foundation-level skills with some of the common operating systems for computingenvironments. •Entry-level understanding of some of the common concepts for networkenvironments, such as routing and switching. •General or practical knowledge of major TCP/IP networking protocols, including,but not limited to, TCP, IP, UDP, DNS, HTTP, ARP, ICMP, and DHCP.

Audience
This course is designed primarily for cybersecurity practitioners preparing for orwhocurrently perform job functions related to protecting information systems by ensuringtheir availability, integrity, authentication, confidentiality, and non-repudiation.Itis ideal for those roles within federal contracting companies and private sector firmswhose mission or strategic objectives require the execution of Defensive CyberOperations (DCO) or DoD Information Network (DoDIN) operation and incident handling.This course focuses on the knowledge, ability, and skills necessary to provide forthedefense of those information systems in a cybersecurity context, including protection,detection, analysis, investigation, and response processes. In addition, the course ensures that all members of an IT team—regardless of size,rank,or budget—understand their role in the cyber defense, incident response, and incidenthandling process.

Topics
In this course, you will understand, assess, and respond to security threats and operatea system and network security analysis platform.
• Compare and contrast various threats and classify threat profiles.
• Explain the purpose and use of attack methods and techniques.
• Explain the purpose and use of post-exploitation tools and tactics.
• Given a scenario, perform ongoing threat landscape research and use data toprepare for incidents.
• Explain the purpose and characteristics of various data sources.
• Given a scenario, use real-time data analysis to detect anomalies.
• Given a scenario, analyze common indicators of potential compromise.
• Given a scenario, use appropriate tools to analyze logs.
• Given a scenario, use appropriate containment methods or tools.
• Given a scenario, use appropriate asset discovery methods or tools.

QUESTION 2
A secretary receives an email from a friend with a picture of a kitten in it. The secretary forwards it to the
~COMPANYWIDE mailing list and, shortly thereafter, users across the company receive the following message:
“You seem tense. Take a deep breath and relax!”
The incident response team is activated and opens the picture in a virtual machine to test it. After a short
analysis, the following code is found in C:
\Temp\chill.exe:Powershell.exe –Command “do {(for /L %i in (2,1,254) do shutdown /r /m Error! Hyperlink
reference not valid.> /f /t / 0 (/c “You seem tense. Take a deep breath and relax!”);Start-Sleep –s 900) } while(1)”
