Q42. In which phase of Lockheed Martin’s – Cyber Kill Chain Methodology, adversary creates a deliverable malicious payload using an exploit and a backdoor?

偵察

Delivery

Weaponization

Exploitation

In the Lockheed Martin Cyber Kill Chain Methodology, the phase where an adversary creates a deliverable malicious payload using an exploit and a backdoor is known as the Weaponization phase. This is the second stage of the Cyber Kill Chain, which occurs after the initial Reconnaissance phase. During Weaponization, the attacker prepares a malicious payload that is designed to exploit vulnerabilities in the target system. This payload often includes a backdoor to allow for persistent access to the compromised system.
The Weaponization phase involves the creation of malware tailored to the target’s specific vulnerabilities discovered during Reconnaissance. The attacker uses this malware to create a weaponized deliverable, which can be transmitted to the target during the subsequent Delivery phase of the Cyber Kill Chain.
References: The EC-Council SOC Analyst course materials and study guides discuss the Cyber Kill Chain Methodology in detail, including the Weaponization phase. These resources are designed to provide SOC Analysts with the knowledge and skills necessary to identify, analyze, and respond to cyber threats effectively.
For further information, please refer to the official EC-Council Certified SOC Analyst (CSA) study guides and related course materials. Additionally, Lockheed Martin provides resources and an overview of the Cyber Kill Chain on their official website12.

Q52. Juliea a SOC analyst, while monitoring logs, noticed large TXT, NULL payloads.
What does this indicate?

Concurrent VPN Connections Attempt

DNS Exfiltration Attempt

Covering Tracks Attempt

DHCP Starvation Attempt

Juliea, the SOC analyst, noticed large TXT and NULL payloads in the logs. This is indicative of a DNS exfiltration attempt. DNS exfiltration is a type of cyber attack where an attacker uses the DNS protocol to sneak data out of a network undetected. It typically involves the use of large TXT records, which can be used to carry data out of the network. NULL payloads can be used in this context to pad the DNS queries and make them less suspicious or to bypass security controls that inspect the content of DNS queries.
The steps involved in DNS exfiltration include:
* The attacker compromises a system within the target network.
* Malware on the compromised system encodes the data it wants to exfiltrate.
* The encoded data is split into chunks that fit into DNS query sizes.
* These chunks are sent as data in DNS queries or responses, often using TXT records.
* An external attacker-controlled server receives the DNS queries and decodes the data.
参考文献
* EC-Council’s Certified SOC Analyst (CSA) course material and study guides provide detailed information on various types of cyber attacks, including DNS exfiltration.
* Online resources and practice questions for the Certified SOC Analyst (CSA) exam also cover this topic and can be used to verify the answer123.
* Additional information on DNS exfiltration techniques and detection methods can be found in security blogs and articles that discuss the subject in depth456.

Q61. Which of the following formula represents the risk?

Risk = Likelihood × Severity × Asset Value

Risk = Likelihood × Consequence × Severity

Risk = Likelihood × Impact × Severity

Risk = Likelihood × Impact × Asset Value

Risk is typically calculated as the product of likelihood, impact, and asset value. Likelihood represents the probability of a threat exploiting a vulnerability, impact refers to the potential damage or loss that could result from the threat, and asset value quantifies the importance or worth of the asset to the organization. The formula ( \text{Risk} = \text{Likelihood} \times \text{Impact} \times \text{Asset Value} ) captures the essence of risk in terms of these three factors.
References: The EC-Council’s Certified SOC Analyst (CSA) program includes training on risk assessment and management, which involves understanding how to calculate and manage risk based on various factors including likelihood, impact, and asset value. The CSA curriculum is designed to align with industry best practices and standards for security operations centers12.

Q62. Which of the following technique involves scanning the headers of IP packets leaving a network to make sure that the unauthorized or malicious traffic never leaves the internal network?

Egress Filtering

Throttling

Rate Limiting

Ingress Filtering

Egress filtering is a network security measure that involves scanning the headers of IP packets as they leave a network. The purpose of this technique is to ensure that unauthorized or malicious traffic does not exit the internal network. This is achieved by implementing rules that define which types of traffic are allowed to leave the network. By filtering outgoing traffic, egress filtering helps prevent data exfiltration and blocks the communication of malware with external command-and-control servers.
References: The EC-Council’s Certified SOC Analyst (CSA) program covers the fundamentals of SOC operations, including the importance of egress filtering in protecting a network’s perimeter. The CSA training and credentialing program provides in-depth knowledge on various SOC processes, such as log management, SIEM deployment, incident detection, and response, which includes the implementation of egress filtering as a security control12.
