Explanation
The server is infected with a virus and SELinux is enabled on the server are most likely causing the issue of unauthorized services running on the server. A virus is a type of malicious software that infects a system and performs unwanted or harmful actions, such as creating, modifying, deleting, or executing files. A virus can also create backdoors or open ports on a system to allow remote access or communication with external sites.
SELinux (Security-Enhanced Linux) is a security module for Linux systems that enforces mandatory access control policies on processes and files. SELinux can prevent unauthorized services from running on a server by restricting their access to resources based on their security context. However, SELinux can also cause problems if it is not configured properly or if it conflicts with other security tools.

Teaming is a technique that can be configured on a server for network redundancy. Teaming involves combining two or more network adapters into a single logical unit that acts as one network interface. This way, if one network adapter fails, another one can take over without disrupting network connectivity. Teaming can also improve network performance by load balancing traffic across multiple network adapters. Clustering is a technique that involves grouping two or more servers together to act as one system for high availability and fault tolerance. Virtualizing is a technique that involves creating multiple virtual machines on a single physical server to optimize resource utilization and flexibility. Cloning is a technique that involves creating an exact copy of a server's configuration and data for backup or migration purposes. References:

Components of a Data Loss Solution
Reference:
The best way to protect the data from leaking is to install a DLP solution. A DLP (Data Loss Prevention) solution is a software that helps businesses prevent confidential data from being leaked or stolen by unauthorized parties. A DLP solution can identify, monitor, and protect data as it moves across networks and devices, such as endpoints, email, web, cloud applications, or removable media. A DLP solution can also enforce security policies based on content and context for data in use, in motion, and at rest. A DLP solution can detect and prevent data breaches by using various techniques, such as content inspection, contextual analysis, encryption, blocking, alerting, warning, quarantining, or other remediation actions.

The write cache is a feature of some RAID controllers that allows them to temporarily store data in a fast memory buffer before writing it to the disk drives. This improves the performance and efficiency of write operations, especially for random and small writes. However, if the battery on the controller goes bad, the controller may disable the write cache to prevent data loss in case of a power failure. This can degrade the disk drive performance significantly, as every write operation will have to wait for the disk drives to complete.
