 Agent-based protection is a type of endpoint security that uses software agents installed on the devices to monitor and protect them. Agent-based protection can collect and detect all traffic locally, which means it can operate without relying on a network connection or a centralized server. Agent-based protection can also provide more granular and comprehensive visibility and control over the devices. 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 2.3: Endpoint Security)

Privileges required is a metric in the Common Vulnerability Scoring System (CVSS) that measures the level of access needed to launch a successful attack. The higher the privileges required, the lower the severity of the vulnerability. The privileges required metric has three possible values: none, low, and high. None means that the attacker does not need any privileges to exploit the vulnerability. Low means that the attacker needs privileges that provide basic user capabilities. High means that the attacker needs privileges that provide significant or administrative control over the target. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 2-17; 200-201 CBROPS - Cisco, exam topic 1.3.c

 Tap and SPAN are two methods of capturing network traffic for analysis. Tap (Test Access Point) is a hardware device that is inserted between two network devices and sends a copy of all traffic to a monitoring device. SPAN (Switched Port Analyzer) is a software feature that allows a network switch to replicate traffic from one or more source ports to a destination port, where a monitoring device is connected. Both methods provide visibility into network traffic, but Tap is more reliable and less intrusive than SPAN, as it does not affect the network performance or introduce errors. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 68.

NAT (Network Address Translation) and PAT (Port Address Translation) are technologies that modify the IP address information in packet headers as they pass through a router or firewall, making it difficult to trace the communication back to the originating end-device.

 A denial-of-service attack represents the evasion technique of resource exhaustion, where the attacker overwhelms a system’s resources, making the system unusable and unable to handle legitimate requests. References := Cisco Cybersecurity Source Documents

Exploitation - The targeted Environment is taken advantage of triggering the threat actor's code

Installation - Backdoor is placed on the victim system allowing the threat actor to maintain the persistence.

Command and Control - An outbound connection is established to an Internet-based controller server.

Actions and Objectives - The threat actor takes actions to violate data integrity and availability

 The attack surface is the sum of all paths for data into and out of the environment, such as network interfaces, applications, services, protocols, ports, and user accounts. The attack surface represents the exposure of the environment to potential threats and attacks. A vulnerability is an exploitable weakness in a system or its design that can allow an attacker to compromise the system or its data. A vulnerability is a subset of the attack surface, as not all paths for data are vulnerable. References: [Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Module 1: Security Concepts]

The regular expression c(rgr)+e matches strings where “rgr” occurs one or more times between “c” and “e”. The string “crgrrgre” fits this pattern as it has the sequence “rgr” repeated twice between “c” and “e”. The plus sign (+) in the regular expression indicates that the preceding element must appear one or more times for a match to occur

A threat agent is the entity that is responsible for initiating a threat action that exploits a vulnerability. A threat agent can be a person, a group, an organization, or a system. In this scenario, the threat agent is the foreign government that hacked the defense contractor and stole the intellectual property. The threat agent’s motivation, capability, and resources determine the level of threat they pose to the target. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 1-3; 200-201 CBROPS - Cisco, exam topic 1.1.b
