Cisco 200-201 Based on Real Exam Environment

The operation described is characteristic of the fork() system call in Linux, which is used to create a new process. The fork() system call generates a new process by duplicating the calling (parent) process. If the fork() is successful, the PID of the child process is returned to the parent process, and a 0 value is returned to the child process. If unsuccessful, a negative value is returned2.

An attack vector is the method or technique that an attacker uses to exploit a vulnerability in a system or network. An attack vector can be a software, hardware, or human component that can be manipulated to gain unauthorized access, execute malicious code, or cause damage. An attack surface is the sum of all the possible attackvectors that are exposed by a system or network. An attack surface can be reduced by applying security measures such as patching, hardening, firewalling, and encrypting. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 1-4; 200-201 CBROPS - Cisco, exam topic 1.1.c

Traffic tapping involves replicating network traffic and sending it to a separate port where it can be analyzed without affecting the original traffic flow. This allows security analysts to monitor and analyze traffic for potential threats without the risk of blocking legitimate traffic.

This explanation is based on general network security concepts, as the current page does not provide specific Cisco documentation.

According to NIST SP800-61, the incident response phase called “Containment, Eradication, and Recovery” involves containing the incident, eradicating the threat, and recovering from the incident2. In the scenario described, the engineer worked on containing the DDoS attack by identifying the attacker and the technique used, which is part of the containment process. The recommendation to implement Blackhole filtering is part of the eradication process, where measures are taken to prevent the attack from happening again. Finally, restoring the server is part of the recovery process, where normal operations are resumed. Therefore, the engineer finished work during the “Containment, Eradication, and Recovery” phase. References: NIST SP800-61 Computer Security Incident Handling Guide2.
