The exhibit shows an event log file with fields like date time action protocol src-ip dst-ip src-port dst-port etc., which are typical in Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS). These systems monitor network traffic for suspicious activity or violations of policies and produce reports as seen in the exhibit.Reference:Cisco Certified CyberOps Associate Overview

Traffic mirroring is a technique that copies the traffic from a source port or VLAN to a destination port or VLAN, where it can be analyzed by a security device or tool. Traffic mirroring does not affect the original traffic flow and does not introduce any latency or modification to the packets. Inline traffic interrogation is a technique that forwards the traffic directly to the security device or tool, where it can be inspected and modified before being sent to the destination. Inline traffic interrogation can introduce latency and affect the performance of the network.Reference:

A man-in-the-middle attack is a type of cyberattack where an attacker intercepts and alters the communication between two parties who believe they are directly communicating with each other. In this case, the attacker is impersonating mail.google.com and presenting a fake certificate to the endpoint device. The endpoint device detects that the certificate is not issued by a trusted authority and displays an error message. The attacker can then monitor or modify the traffic between the endpoint device and mail.google.com.Reference:

A regular expression (regex) is a sequence of characters that defines a search pattern for text. A regex can be used to extract custom properties from log messages or events in a SIEM platform. In this case, the regex that matches the phrase ''File: Clean'' exactly is ^File: Clean$. The ^ symbol indicates the beginning of the line and the $ symbol indicates the end of the line. The regex ensures that no other characters are before or after the phrase.Reference:

Availability is one of the three pillars of the CIA triad, a model that defines the principles of information security. Availability describes the concept of data consistently and readily being accessible for legitimate users. Availability ensures that the network and systems are operational and resilient to disruptions, such as denial-of-service attacks, hardware failures, or natural disasters. Availability also involves maintaining backup and recovery procedures, load balancing, and redundancy mechanisms.Reference:

The file that is extractable via TCP stream within Wireshark is the one that has the Content-Type header set to application/octet-stream, which indicates binary data. This header is present in frames 7, 14, and 21, which are part of the same TCP stream. The other frames have different Content-Type headers, such as text/html or image/jpeg, which are not extractable as binary files.Reference:= Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 3: Network Intrusion Analysis, Lesson 3.2: Analyze Data from Common TCP/IP Protocols, Topic 3.2.3: HTTP

When a company workstation is compromised, the stakeholders that must be involved are the ones who are responsible for the security incident response process. According to the table, these are Employee 4 (Security Operation Center Analyst), Employee 6 (Head of Network and Security Infrastructure Services), and Employee 7 (Technical Director). The other employees have different roles that are not directly related to the incident response process, such as accounting, financial management, or system administration.Reference:= Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 1: Security Concepts, Lesson 1.4: Security Monitoring, Topic 1.4.1: Security Operations Center

An attack surface is the sum of all the points where an attacker can try to enter or extract data from an environment. It includes all the hardware, software, network, and human components that are exposed to potential threats. An attack vector is the path or means by which an attacker can exploit a vulnerability in the attack surface. It describes the type, source, and technique of an attack, such as phishing, malware, denial-of-service, etc.Reference:= Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 1: Security Concepts, Lesson 1.1: The CIA Triad and Security Concepts, Topic 1.1.3: Threats, Vulnerabilities, and Exploits

TOR is a network that enables anonymous communication over the internet by routing the traffic through a series of relays or nodes. TOR alters the data content during transit by encrypting it and the destination information over multiple layers, using a technique called onion routing. Each layer of encryption can only be decrypted by a specific relay in the network, which reveals the next destination. This way, no single relay knows the complete path or the content of the data, making it difficult to trace or monitor the communication.Reference:= Cisco Cybersecurity Operations Fundamentals, Module 2: Security Monitoring, Lesson 2.1: The Network as a Sensor, Topic 2.1.3: Network Data Exfiltration Techniques
