In the PaaS (Platform as a Service) cloud service model, the cloud provider manages the infrastructure, including network, servers, operating systems, and storage. The organization’s responsibility is primarily at the application level, which includes the data, interfaces, and the applications themselves. This means the organization must ensure the security and compliance of their data, manage the applications they develop or deploy, and handle the interfaces that connect their applications to other services or users. References: The Certified Network Defender (CND) course by EC-Council discusses the shared responsibility model in cloud services, emphasizing the division of responsibilities between the cloud provider and the consumer123.

Disaster Recovery (DR) is a subset of business continuity planning which focuses on the IT systems and operations of a business after a disaster. It’s a comprehensive approach that ensures all critical business functions can be resumed quickly and effectively in the event of a crisis. DR is not just about data or security; it encompasses all aspects of the business that are necessary to continue operations and protect the interests of stakeholders.

References: The explanation aligns with the objectives and documents of the EC-Council’s Certified Network Defender (CND) program, which emphasizes the importance of business continuity and disaster recovery as part of a defense-in-depth security strategy. This includes protecting endpoints, data, and networks, as well as continuous threat monitoring and response12345.

The SOC manager reviewing logs in AlienVault USM to investigate an intrusion is employing a reactive approach. This approach is characterized by actions taken in response to an event or incident that has already occurred. In this context, the SOC manager is analyzing the logs to understand the intrusion after it has been detected, which is a form of reactive security measure.

References: The use of AlienVault USM for log review and intrusion investigation is a common practice in Security Operations Centers (SOCs) as part of their incident response procedures, which is a reactive approach to cybersecurity threats1.

A packet filtering firewall operates at the network layer of the TCP/IP model. It analyzes the headers of IP packets, which include source and destination IP addresses, protocol information, and port numbers, to determine whether to allow or block the packets based on predefined rules and access control lists (ACLs). This type of firewall does not perform deep packet inspection but rather checks the packet headers against the ACLs to make decisions1234.

References: The explanation aligns with the core functions of packet filtering firewalls as described in various sources, including the Enterprise Networking Planet and NordLayer articles, which detail how these firewalls interact with the IP layer to filter traffic12. GeeksforGeeks also confirms that packet filtering firewalls work at the network layer of the OSI model, which corresponds to the IP layer in the TCP/IP model4.
