• Defense-in-depth is a layered security strategy that aims to protect information and resources through multiple security measures.
• One of its key principles is the concept of least privilege, which means providing users and systems with the minimum level of access necessary to perform their job functions.
• By assigning only the necessary permissions, the attack surface is reduced, and the potential damage from a compromised account or system is minimized.
• This principle helps in mitigating the risk of unauthorized access and limits the capabilities of an attacker if they gain access to an account.

 DNS amplification is a type of Distributed Denial of Service (DDoS) attack where an attacker uses publicly accessible open DNS servers to flood a target with DNS response traffic. The goal is to overwhelm the target with traffic, causing a denial of service.

• In the Common Vulnerability Scoring System (CVSS), attack complexity refers to the conditions beyond the attacker’s control that must exist for the vulnerability to be successfully exploited.
• This includes factors such as the need for user interaction, the presence of specific configurations, or network conditions that are not easily controlled by the attacker.
• A high attack complexity means that these external factors make exploitation more difficult, while a low attack complexity indicates that fewer such conditions are required.

Social engineering is a tactic used by attackers to manipulate individuals into divulging confidential information, such as passwords. In this scenario, the attacker is impersonating a colleague by using a similar email address with a missing letter, attempting to trick the employee into revealing sensitive information.

References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course and materials provide insights into various types of cybersecurity threats, including social engineering, and how to recognize and respond to them.

 Phishing is considered a low-bandwidth attack because it does not require the use of significant network resources. Instead, it relies on social engineering to deceive individuals into providing sensitive information or clicking on malicious links, often through email or other communication methods1.

• The security scenario involves protecting the company from known issues that trigger adware and addressing a recent incident that could harm the system.
• This scenario involves identifying vulnerabilities (weaknesses in the system that can be exploited) and threats (potential harm that can exploit these vulnerabilities).
• A vulnerability is an inherent flaw in the system, while a threat is an event or condition that has the potential to exploit the vulnerability.
• The security engineer needs to assess both the vulnerabilities present and the threats that could exploit these vulnerabilities to implement effective protection measures.

 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)

 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

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
