As a first responder to a suspected DoS incident, the initial step is to make an assessment of the situation. This involves analyzing the network traffic using tools like Wireshark to confirm the nature of the traffic and determine if it is indeed a DoS attack. The assessment will help in understanding the scope and impact of the incident and is crucial for deciding the subsequent steps in the response process123.

References: The importance of making an initial assessment is highlighted in various cybersecurity incident response guidelines and best practices, which recommend starting with an evaluation of the situation before proceeding with any other actions123.

SIEM (Security Information and Event Management) solutions are designed to provide a comprehensive view of an organization’s security status by collecting and analyzing security-related data from various sources. To enhance their capabilities, SIEM solutions consume threat intelligence feeds, which are streams of data that provide information about current and potential security threats. These feeds include details such as indicators of compromise (IoCs), tactics, techniques, and procedures (TTPs) used by cybercriminals, and vulnerabilities in software or systems. By integrating threat intelligence feeds, SIEM solutions can improve real-time threat detection, reduce false positives, and support proactive, intelligence-driven defense strategies. This integration allows organizations to stay one step ahead of emerging threats and advisories, providing insights intothe attacker’s TTPs and associated IoCs that can accelerate investigation and response efforts1.

References: The explanation is based on the general knowledge of SIEM solutions and their use of threat intelligence feeds to enhance security operations. For detailed and specific references, please consult the latest Certified Network Defender (CND) study materials and documents provided by the EC-Council.

Single-sign-on (SSO) is an authentication process that allows a user to access multiple applications with one set of login credentials. This is particularly useful in an environment where employees need to access a variety of systems and applications, as it simplifies the user experience and reduces the need for multiple passwords. SSO is designed to alleviate the administrative burden of managing multiple sets of credentials and toimprove security by reducing the likelihood of password fatigue, which can lead to weak password practices.

References: The concept of SSO is covered in the Certified Network Defender (CND) course, which includes understanding various types of authentication methods. SSO is mentioned as a type of authentication that allows users to be authenticated once and gain access to multiple systems without being prompted to log in again for each system1.

The RAID level that splits data into blocks and evenly writes the data to multiple hard drives without providing data redundancy is known as RAID 0. This RAID level is also referred to as striping. It requires a minimum of two drives to set up. RAID 0 enhances performance by allowing simultaneous read and write operations across the drives, but it does not offer any fault tolerance. If one drive fails, all data in the array is lost because there is no redundancy.

References: RAID 0 is defined by its ability to increase performance by striping data across at least two drives. This information is consistent with the standards and descriptions provided in the EC-Council’s Certified Network Defender (C|ND) course materials and other authoritative sources on RAID configurations123.
