Final answer:
Firewall and antivirus features are not specifically required for a SAN as it operates within a controlled internal network, isolated from the public internet. User access control is critical for SAN security, however.
Step-by-step explanation:
The question pertains to the security features that are not required in a Storage Area Network (SAN). The options given are:
- Firewall
- Antivirus
- User access control
- None of the above
Storage Area Networks are high-speed, dedicated networks that provide access to consolidated block-level storage. Primarily, SANs are designed to handle large volumes of data with fast performance and uptime. When considering the security features necessary for a SAN, it is important to understand the environment in which the SAN operates.
A firewall is typically used to manage and control network traffic based on predetermined security rules, mostly at the entry and exit points of a network. An antivirus program is used to prevent, detect, and remove malware. User access control ensures that only authorized users can access certain data within the SAN. Among the options provided, a firewall and antivirus are not specifically required for a SAN because SANs are usually shielded from the public internet and operate within a controlled internal network. Therefore, user access control is a critical security feature for a SAN, while the use of antivirus and firewall is more related to protecting systems that interact with external threats. The correct answer should be that both firewall and antivirus are not required within the core of a SAN, though they might be necessary on endpoint devices that interact with the SAN.
