Storage Area Network (SAN), which is a dedicated high-speed network that connects servers to storage devices, allowing for the sharing of storage resources. A SAN is designed to handle large amounts of data and provides a way to centralize storage management, making it an efficient solution for enterprises that require reliable and scalable storage infrastructure. It separates the storage units from the servers and the user network, which aligns with the scenario described for Timothy’s organization.

References: The concept of a SAN as a dedicated network for sharing storage resources is well-documented and aligns with industry standards and practices1234.

Asymmetric encryption, also known as public-key cryptography, involves two keys: a public key, which can be shared widely, and a private key, which is kept confidential. The public key is used for encryption, and the private key is used for decryption. This method is scalable because it allows for secure communication over an open network without the need for the parties to share secret keys in advance. While asymmetric encryption is generally slower than symmetric encryption due to the complex mathematical computations involved, it provides a high level of security and is essential for tasks such as digital signatures and establishing secure connections over the internet1234.

John should implement a Proactive security approach. This approach is part of the adaptive security strategy that is built on a 4-pronged approach — Protect, Detect, Respond, and Predict1. By being proactive, John can anticipate potential threats and vulnerabilities and take steps to mitigate them before they can be exploited. This is in contrast to reactive or retrospective approaches, which deal with threats after they have occurred. The proactive approach is aligned with the Certified Network Defender (CND) program’s emphasis on preparing network defenders to identify parts of an organization that need to be reviewed and tested for security vulnerabilities, and how to reduce, prevent, and mitigate risks in the network2345.

In Ubuntu, to terminate a specific process, you would use the kill command followed by the signal you want to send and the Process ID (PID) of the target process. The -9 signal is the SIGKILL signal, which forcefully terminates the process. The correct syntax is kill -9 [PID], where [PID] is replaced with the actual numerical ID of the process you wish to terminate.

References: This information is consistent with standard Linux documentation and practices as well as the Certified Network Defender (CND) course material, which covers system administration and security tasks including process management. The kill command is a fundamental tool for process management in Unix-like operating systems, which is covered in the CND curriculum.
