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.

Indicators of Compromise (IoCs) are clues, artifacts, or evidence that suggest a potential intrusion or malicious activity within an organization's infrastructure. IoCs are used to identify and respond to security breaches and can include log entries, file hashes, unusual network traffic, or specific patterns that match known threats.

• Indicators of Attack (IoA): Focus on detecting the methods and techniques used by attackers.
• Key Risk Indicators: Metrics that indicate increased risk levels.
• Indicators of Exposure: Signs that reveal vulnerabilities or weaknesses in the system.

The zero-trust model is a security concept centered on the belief that organizations should not automatically trust anything inside or outside its perimeters and instead must verify anything and everything trying to connect to its systems before granting access. The Software Defined Perimeter (SDP) aligns with this model by creating a dynamic, context-aware, and secure boundary around network resources. SDP controls access to resources based on identity, authentication, and authorization, ensuring that only authenticated and authorized users or systems can access the services they require. This approach minimizes the attack surface by hiding network resources from unauthorized or unauthenticated users, which is a core principle of zero-trust security.

References: The information aligns with the principles of zero-trust security as outlined in the NIST 800-207 standard for Zero Trust1 and is supported by the Cloud Security Alliance’s documentation on Software-Defined Perimeter (SDP) and Zero Trust2. Additionally, the relationship between SDP and zero-trust is discussed in various industry sources, highlighting SDP as an architecture that enables the zero-trust model by providing secure and authenticated access to network resources34.
