Disabling unused services reduces the server's attack surface by eliminating unnecessary running processes that could be exploited, making it a core operating system-level hardening step performed early in secure server configuration.

A login script is a file that contains commands or instructions that are executed when a user logs into a system or network. A login script can be used to map a network drive to a user profile, which means that the user will have access to a shared folder or resource on another computer or server. A login script can be written in various languages, such as batch, PowerShell, or VBScript, and can be assigned to a user or a group using tools such as Group Policy or Active Directory . A system service (A) is a program that runs in the background and performs tasks that are essential for the operation of the system, such as security, networking, or hardware management. A system service does not map a network drive to a user profile. A network service (B) is a program that provides functionality or resources to other programs or devices over a network, such as file sharing, printing, or web hosting. A network service does not map a network drive to a user profile. A kickstart script (D) is a file that contains configuration settings and commands for automated installation of Linux operating systems. A kickstart script does not map a network drive to a user profile.

Data-at-rest encryption is a method of encrypting data while it is stored on a storage device, such as a hard drive, an SSD, or a tape library. This ensures that if the data is stolen or lost, it will be unreadable without the encryption key. Data-at-rest encryption does not protect data while it is in transit over the network, in use by the CPU or memory, or attached to an email.

Active Directory (AD) allows administrators to manage and apply Group Policies across multiple computers and users within a domain. By using AD, the senior administrator can create or modify Group Policy Objects (GPOs) to enforce restrictions, such as preventing software installation on the server in question. This approach provides centralized management and enforcement of security settings across the network.

RAID 10 would yield 2 mirrored sets of 2 drives x 200GB = 400GB
