 Social engineering attacks are techniques that exploit human psychology and behavior to manipulate or deceive people into performing actions or divulging information that can compromise the security of the organization. An example of a social engineering attack is receiving an email from human resources requesting a visit to their secure website to update contact information. This could be a phishing attempt to trick the user into clicking on a malicious link or entering their credentials on a fake website that looks like the legitimate one. References := Cisco Cybersecurity Operations Fundamentals - Module 6: Security Incident Investigations

The Zero Trust security model operates on the principle that no one is trusted by default from inside or outside the network, and verification is required from everyone trying to gain access to resources on the network. It emphasizes continuous monitoring, validation, and least-privilege access to minimize exposure to sensitive parts of the network.

A Certificate Authority (CA) is responsible for issuing digital certificates to validate the identity of the certificate holder and provide a means to establish secure communications over networks like the Internet. References := Cisco Cybersecurity Source Documents

 CDFS stands for Compact Disc File System, which is a file system used by Mac OS to store data on CDs. CDFS is also known as ISO 9660, which is a standard format for data interchange on optical discs. CDFS allows files to be accessed by different operating systems, such as Windows, Linux, and Mac OS. Therefore, an ISO file that is stored in CDFS format is data from a CD copied using Mac-based system. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 4: Network Intrusion Analysis, Lesson 4.4: File Type Analysis, Topic 4.4.1: File Systems, page 4-40.

The regular expression provided is:.\.(pd][Oo][Cc)|[Xx][LI][Ss]|[Pp][Pp][Tt]) HTTP/1 .[01]

This regular expression is designed to match file extensions for Word (.doc), Excel (.xls), and PowerPoint (.ppt) files in HTTP network sessions.

The regular expression uses character classes and alternatives to match different case variations of these file extensions.

The part.\.(pd][Oo][Cc)|[Xx][LI][Ss]|[Pp][Pp][Tt])matches the file extensions, andHTTP/1 .[01]ensures that the match is in the context of HTTP version 1.0 or 1.1.

 CIA stands for confidentiality, integrity, and availability, which are the three main objectives of information security. Confidentiality means protecting the information from unauthorized access or disclosure. Integrity means ensuring the information is accurate and consistent, and preventing unauthorized modification or deletion. Availability means ensuring the information and systems are accessible and usable by authorized users when needed. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1.0/CSCU-LP-CBROPS-V1-028093.html (Module 2: Security Concepts, Lesson 2.1: Security Principles)

To search for additional downloads of a malicious file by other hosts, the file hash value is needed. The hash value provides a unique identifier for each specific file version, enabling cybersecurity professionals to track down identical files across networks. References := Cisco Certified CyberOps Associate Overview

When analyzing Wireshark traffic for potential attacks, an engineer should look for patterns that indicate abnormal behavior, such as:

Excessive Requests: A high number of requests over a short period could suggest an attempt to overwhelm the server, known as an HTTP flood.

Status Codes: Repeated 403 Forbidden responses may indicate that the server is rejecting requests due to a security rule being triggered.

Request Types: A mix of GET and POST requests could be used in various attack scenarios, including bandwidth flooding or cache bypassing.

A sandbox is a technology on a host that is used to isolate a running application from other applications. A sandbox creates a controlled and restricted environment for the application to execute, limiting its access to system resources and data. A sandbox can prevent the application from spreading malware, stealing information, or causing damage to the host or the network. A sandbox can also be used to test and analyze the behavior of unknown or suspicious applications without risking the security of the host. Application allow list, application block list, and host-based firewall are other technologies on a host that can be used to control or restrict the execution of applications, but they do not isolate them from other applications. References:
