The RAID level used here is RAID 1, which is also known as disk mirroring. In this setup, all the data written to one disk is automatically copied to another disk, creating an exact duplicate of the data. This ensures that if one disk fails, the data is still available on the other disk, providing redundancy and protecting against data loss. RAID 1 is a common choice for systems where data availability and integrity are critical.

References: This explanation is consistent with the principles outlined in the EC-Council’s Certified Network Defender (CND) course materials, which describe RAID 1 as a configuration that duplicates data across multiple disks to ensure redundancy and data availability1.

The countermeasures to deal with future malware incidents involve a multi-layered approach that includes:

• Complying with the company’s security policies: Ensuring that all security policies are followed can prevent malware incidents by maintaining a secure network environment.
• Implementing strong authentication schemes: Strong authentication can prevent unauthorized access, reducing the risk of malware being introduced by attackers.
• Implementing a strong password policy: Robust password policies can deter attackers by making it more difficult to gain access through brute force or other password-related attacks.
• Install antivirus software: Antivirus software is essential for detecting, preventing, and removing malware from the network.

These measures align with the Certified Network Defender (CND) program’s emphasis on a defense-in-depth strategy, which includes protecting endpoints, data, and networks, as well as continuous threat monitoring and response123.

 In Public Key Infrastructure (PKI), the Certificate Authority (CA) is responsible for issuing digital certificates. The CA validates entities and binds their public keys with their respective identities through a process of registration and issuance of certificates. This process can be automated or carried out under human supervision. The Registration Authority (RA) often assists the CA by handling the vetting of certificate requests and authenticating the entity making the request, but it does not issue certificates. The CA maintains the integrity of the binding by ensuring that the certificates are issued according to industry norms and best practices, and it also manages the revocation of certificates when necessary.

References: The explanation is based on the standard roles and responsibilities defined within a PKI as outlined in various sources, including the Internet Engineering Task Force’s RFC 36471, which details the functions of an RA and clarifies that only a CA has the authority to issue certificates2345.

SRAM, or Static Random-Access Memory, is known for its low access time, typically around 20 ns, which makes it suitable for applications requiring high speed, such as cache memory in computers or, in this case, a RAID system. SRAM is faster than DRAM because it does not need to be refreshed as often, which is why it’s used where speed is critical. Although SRAM is more expensive and has less density compared to other types of RAM, its speed advantage makes it the preferred choice for Brendan’s RAID system requirements.

References: The characteristics of SRAM are well-documented in computer architecture and hardware literature, aligning with the Certified Network Defender (CND) course’s focus on understanding different types of memory for network security purposes. The ECCouncil’s CND materials and study guides provide information on various hardware components and their relevance to network security, which includes the selection of appropriate RAM types for different systems123.
